The logarithm expression is approximately 4.6.
How to evaluate the expression with which logarithmic identity?To evaluate 9㏒₉⁵ - ㏒₃3⁵, we can use the logarithmic property that states:
㏒ₐ(b^c) = c x ㏒ₐ(b)
Using this property, we can simplify the expression as follows:
9㏒₉⁵ - ㏒₃3⁵
= ㏒₉(95^9) - ㏒₃(35)
= ㏒₉(1423892081) - ㏒₃(35)
We can evaluate these logarithmic terms using the change of base formula, which states:
㏒ₐ(b) = log(b) / log(a)
Using this formula, we get:
㏒₉(1423892081) = 8.032
㏒₃(35) = 3.432
Substituting these values back into the expression, we get:
9㏒₉⁵ - ㏒₃3⁵ = 8.032 - 3.432
= 4.6

Answers
The area of the Tri-Tri-Again board game is 3 1/8 square feet.
To calculate the area of a triangle, we need to know the length of its base and its height. In this case, Bridget's Tri-Tri-Again board game is in the shape of a triangle with a base of 1 1/4 feet and a height of 2 1/2 feet. To find the area of the triangle, we can use the formula for the area of a triangle, which is 1/2 x base x height.
We first convert the mixed numbers to improper fractions. The base is 5/4 feet and the height is 5/2 feet. We can then substitute these values into the formula to get:
Area of triangle = 1/2 x 5/4 feet x 5/2 feet
Area of triangle = 25/8 square feet
We can simplify the answer by dividing the numerator and denominator by the greatest common factor of 25 and 8, which is 1. This gives us:
Area of triangle = 25/8 square feet
Area of triangle = 3 1/8 square feet
Therefore, the area of the Tri-Tri-Again board game is 3 1/8 square feet.

What is the possible range for sizes x when u have 4.1 and 1.3
Answers
The possible range of x in the triangle is (2.8,∞)
According to the triangle inequality theorem, any two sides' sums in a triangle must be bigger than the length of the third side. If a, b, and c are the lengths of a triangle's sides, then the sum of a and b's lengths is greater than c's length. Similar to how a+ c > b, b + c > a.
By applying the triangle inequality theorem, which asserts that if the sides have lengths a, b, and c, then a + c > b, it is feasible to determine the range of sizes for x. Let a = 4, 1, and 3 and c = x. Our range of values for x is as follows because measurements of length and distance can never be negative:
a + c > b 4.1 + x > 1.3 x > -2.8
Hence, x's potential size range is (-2.8, infinity).

Lola has 4 1/2 cups of rice. She uses 3/4 of the rice to make sushi rolls for dinner. She uses the rest of the rice to make rice pudding for dessert. How much rice does Lola use for the rice pudding?
Answers
Lola has 9/8 cups of rice left to use for the rice pudding.
What is fraction?
A fraction is a mathematical term that represents a part of a whole or a ratio between two quantities.
To find out how much rice Lola uses for the rice pudding, we need to first determine how much rice she used for the sushi rolls.
Lola used 3/4 of the 4 1/2 cups of rice for the sushi rolls. To calculate this, we can multiply:
4 1/2 cups x 3/4 = (9/2) x (3/4) = 27/8 cups
So Lola used 27/8 cups of rice for the sushi rolls.
To find out how much rice Lola has left for the rice pudding, we need to subtract the amount she used for the sushi rolls from the original amount of rice she had:
4 1/2 cups - 27/8 cups = 36/8 cups - 27/8 cups = 9/8 cups
Therefore, Lola has 9/8 cups of rice left to use for the rice pudding.

a random sample of 100,000 credit sales in a department store showed an average sale of $87.25. from past data, it is known that the standard deviation of the population is $20.00. what is the 95% confidence interval of the population mean?
Answers
The 95% confidence interval of the population mean for the given sample is between $86.96 and $87.54.
To calculate the confidence interval, we need to use the formula:
CI = [tex]\bar{X}[/tex] ± Zα/2 * σ/√n
where,
[tex]\bar{X}[/tex] = sample mean = $87.25
Zα/2 = the Z-score for 95% confidence level = 1.96
σ = population standard deviation = $20.00
n = sample size = 100,000
Plugging these values in the formula, we get:
CI = 87.25 [tex]\pm[/tex] 1.96 * (20/√100,000)
CI = 87.25 [tex]\pm[/tex] 0.098
Therefore, the 95% confidence interval of the population mean is between $86.96 and $87.54. This means that we can be 95% confident that the true population mean lies within this interval.

Answers
a) The smallest number of people required to satisfy the conditions is 10.
b) The next smallest number of people required to satisfy the conditions is 70.
This is a problem of finding the least common multiple (LCM) of three numbers with given remainders. The LCM is the smallest number that is divisible by all three numbers and leaves the given remainders.
Let's call the number of people "n". We know that
n ≡ 1 (mod 3)
n ≡ 2 (mod 4)
n ≡ 3 (mod 5)
To find the LCM, we can use the Chinese remainder theorem or a simpler method is to use trial and error starting from the given remainders.
Starting from n ≡ 1 (mod 3), we can add multiples of 3 until we find a number that satisfies the other two conditions. Trying n = 4, 7, 10, ... we find that n = 10 satisfies all three conditions
10 ≡ 1 (mod 3)
10 ≡ 2 (mod 4)
10 ≡ 3 (mod 5)
Therefore, the smallest number of people required to satisfy the conditions is 10.
To find the next smallest number, we can add the LCM of 3, 4, and 5 to 10. The LCM of 3, 4, and 5 is 60, so the next smallest number is 70
70 ≡ 1 (mod 3)
70 ≡ 2 (mod 4)
70 ≡ 3 (mod 5)
Therefore, the next smallest number of people required to satisfy the conditions is 70.

What is a hexagon?A hexagon is a six-sided polygon in geometry.
Any simple hexagon has 720° of internal angles in total.
In geometry, a hexagon is a six-sided polygon.
Each internal angle and the side length of a regular hexagon are both 120 degrees.
Hexagon is one of many nouns in science and mathematics that has Greek roots.
The concept of a six-sided shape is derived from the Greek word hexágnon, where the word gonia mean "angle."
This makes sense because a hexagon includes not only six sides, but also six angles, or vertices.
So, we know we have equilateral triangles:
Area = 1/2 * base * height
Insert values as follows:
Area = 1/2 * base * height
Area = 1/2 * 7 * 7
Area = 1/2 * 49
Area = 24.5 cm²
Then, the area of the hexagonal tile:
24.5 * 6 = 147 cm²
Then, 147/7 = 21 cm²

The appropriate theorem used to solve this inequality is the subtraction property of inequalities, which states that if a < b, then a - c < b - c for any real number c. In this case, we subtracted 7 from both sides of the inequality to isolate m.
What is the inequalities theorem?It says [tex]"7+m < 6=200"[/tex] which has an equal sign in between 6 and 200, which does not make sense. I will assume that the inequality you meant to provide is:
[tex]7+m < 6[/tex]

Simplifying the left-hand side and the right-hand side, we get:
[tex]m < -1[/tex]
Therefore, the solution to the inequality [tex]7+m < 6[/tex] is:
m < -1
We can verify this solution by plugging in a value of m that is less than -1, such as -2, into the original inequality:

Answers
Answer:
5
Step-by-step explanation:
Cost of bagels = 50 - 1.75 - 33.5 = 14.75
No. of bagels = 14.75/2.95 = 5
Answer:
You bought 5 bagels.
Step-by-step explanation:
Since you buy a coffee every day and it says "after 10 days" you multiply the price of the coffee by 10: $3.35 * 10 = $33.5
It also says that the remaining balance on the gift card is $1.75. So you need to subtract that from the original balance, 50: $50- $1.75 = $48.25 - this is the amount of money you spent.
Next, you subtract the price of all the coffees you bought from the amount of total money you spent over the course of 10 days. $48.25 - $33.5 = $14.75
This remaining money is for the bagels that you bought on some days. The last step should be to divide $14.75 by the price of one single bagel:
$14.75 / 2.95 = 5
You bought 5 bagels.

a . (–4 + i) + 4i = –4 + (i + 4i).The associative property of addition states that the grouping of the numbers being added does not change their sum.
In option (a), the expression on the left-hand side can be grouped as (–4 + i) + 4i, and the expression on the right-hand side can be grouped as –4 + (i + 4i). Both expressions result in the same sum of –4 + 5i. Therefore, option (a) demonstrates the associative property of addition.
The associative property of addition is a mathematical property that states that the grouping of the numbers being added does not affect their sum. In other words, when adding three or more numbers, the order in which the numbers are grouped for addition does not affect the result. Mathematically, the associative property of addition can be expressed as:
(a + b) + c = a + (b + c)
This property holds for any real numbers a, b, and c. The associative property of addition is a fundamental property of arithmetic and is used extensively in algebraic manipulations to simplify expressions and solve equations.

what is interest ?The sum of money that even a lender charges a loan for the usage of money over a certain period of time is known as interest. It is frequently represented as a proportion of the sum lent or borrowed and can be either simple or compound. Simple interest is determined by that of the principal amount alone, while interest expense is determined by the principal amount and the total amount of interest that has accrued. A key idea in banking, interest is utilised in a number of credit derivatives, including bonds, savings accounts, and loans.
given
May would save on interest costs if she chose a 15-year simple interest mortgage because the loan would be repaid sooner. Using the same technique as before but with n = 15 years, we can determine the interest costs for a 15-year mortgage:
PV is equal to PMT* [1 - (1 + r/12)(-n*12)] / (r/12)
Inputting the values provided yields:
355000 = PMT * [1 - (1 + 0.595%/12)^(-15*12)] / (0.595%/12)
PMT = $3,208.59
Over the course of the loan, the following would be paid in interest:
I equals PMT*n - PV.
I = $3,208.59 * 15 - $355,000
I = $177,279.15
May would therefore save $621,470.85 in interest costs if she opted for a 15-year simple interest mortgage ($798,750 - $177,279.15).

Substituting the values given in the problem, we have:
60 = 2(x + 3x)
Simplifying, we get:
60 = 8x
Dividing both sides by 8, we get:
x = 7.5
Now that we know the length, we can find the width:
width = 3x = 3(7.5) = 22.5
Therefore, the width of the rectangle is 22.5.
Answer:
Answer: 22.5
Step-by-step explanation:
Let L be the length of the rectangle, and W be the width.
From the problem, we know that:
The perimeter of the rectangle is 60, which means that:
2(L + W) = 60
L + W = 30
The width is 3 times the length:
W = 3L
Substituting W = 3L into the first equation, we get:
L + 3L = 30
4L = 30
L = 7.5
Therefore, the width is:
W = 3L = 3(7.5) = 22.5
So, the width of the rectangle is 22.5. Answer: 22.5

A)In 30 minutes, Bobby's dog can cover x miles.(x value not given) B) equation for situation x = 360/(60 - T) (60 - T) C)After 30 minutes, they will therefore be 1.5 times as far apart from one another.
Describe miles?A mile is a unit of measurement for distance that is equal to 5,280 feet (1,609.344 meters) or 5,280 ft. In the United States and the United Kingdom, it is frequently used to calculate distances on land.
A)
If Bobby's cat moves at a speed of x mph and Bobby's dog moves at a speed of 2 mph, then Bobby's cat moves at x mph.
Bobby's dog can run a certain distance in 30 minutes according to the following formula:
Distance is determined by speed and time.
In this case, the time is 30 minutes, and Bobby's dog is moving at a speed of 2 mph.
30 minutes are converted to hours, giving us:
60 hours / 30 minutes=0.5 hours.
Bobby's dog can cover the following distance in 30 minutes:
miles are calculated using the formula distance = speed time (2x) (0.5).
Hence, in 30 minutes, Bobby's dog can cover x miles.
B)
If Bobby's cat moves at a speed of x mph and Bobby's dog moves at a speed of 2 mph, then Bobby's cat moves at x mph.
Imagine if after 30 minutes Bobby's dog and cat were 6 miles apart.
Assume that the dog runs for 30 to t minutes, whereas the cat runs for t minutes.
The cat's journey's mileage is then:
Distance = speed x (t/60) = time (xt/60 miles)
Similar to how the dog travelled, the distance is:
(Speed - Time)/60 = x(30 - T)/30 miles; distance = speed - time - 2x;
After 30 minutes, they were 6 miles apart, thus we can write:
The sum of the distances covered by the dog and the cat is six.
xt/60 + x(30 - t)/30 = 6
When we multiply both sides by 60, we obtain:
xt + 2x(30 - t) = 360
When we simplify the equation, we obtain:
xt + 60x - 2xt = 360
60x - xt = 360
x(60 - t) = 360
x = 360/(60 - t) (60 - t)
Hence, we can formulate the equation for this circumstance as follows:
x = 360/(60 - t) (60 - t)
C)
If Bobby's cat moves at a speed of x mph and Bobby's dog moves at a speed of 2 mph, then Bobby's cat moves at x mph.
If the dog and cat begin to flee from one another, their relative speed is:
relative speed is calculated as follows: cat + dog
= x + 2x
= 3x mph
After 30 minutes, their distance may be calculated using the following formula:
Distance is determined by speed and time.
The time is 30 minutes, and the relative speed is 3x mph.
30 minutes are converted to hours, giving us:
60 hours/ 30 minutes= 0.5 hours.
As a result, after 30 minutes, they will be separated by the following distance:
1.5 miles= 3 times the speed times .
After 30 minutes, they will therefore be 1.5 times as far apart from one another.

Trapezoids and Kites proving trapezoid theorems
Answers
Therefore, the diagonal that connects the midpoints of the other two sides of the kite bisects the other diagonal.
What is trapezoid?A trapezoid is a quadrilateral with at least one pair of parallel sides. The parallel sides are called the bases of the trapezoid, and the non-parallel sides are called the legs. A trapezoid can have two pairs of parallel sides, in which case it is called a parallelogram.
Here,
First, let's define what a trapezoid and a kite are:
A trapezoid is a quadrilateral with at least one pair of parallel sides. The parallel sides are called the bases of the trapezoid.
A kite is a quadrilateral with two pairs of adjacent sides of equal length.
Now, let's look at some common trapezoid theorems and how to prove them:
The bases of a trapezoid are parallel.
To prove this theorem, we can use the fact that opposite angles of a parallelogram are equal. Since the bases of a trapezoid are parallel, we can draw a line segment that connects the endpoints of the non-parallel sides to form a parallelogram. The opposite angles of the parallelogram are equal, so the opposite angles of the trapezoid are also equal. Therefore, the bases of a trapezoid are parallel.
The legs of a trapezoid are congruent.
To prove this theorem, we can use the fact that a trapezoid can be divided into two triangles by drawing a diagonal. Since the bases of a trapezoid are parallel, the diagonal divides the trapezoid into two congruent triangles. Therefore, the legs of a trapezoid are congruent.
The diagonals of a trapezoid bisect each other.
To prove this theorem, we can use the fact that a trapezoid can be divided into two triangles by drawing a diagonal. Since the bases of a trapezoid are parallel, the diagonal divides the trapezoid into two congruent triangles. The diagonals of the trapezoid connect the midpoints of the non-parallel sides of the triangles, which are also the midpoints of the legs of the trapezoid. Therefore, the diagonals of a trapezoid bisect each other.
Now, let's look at some common kite theorems and how to prove them:
The diagonals of a kite are perpendicular.
To prove this theorem, we can use the fact that a kite can be divided into four right triangles. Since two pairs of adjacent sides of a kite are equal in length, the right triangles that share a common vertex have one leg that is perpendicular to the other leg. Therefore, the diagonals of a kite are perpendicular.
One diagonal of a kite bisects the other diagonal.
To prove this theorem, we can use the fact that a kite can be divided into four triangles. Since two pairs of adjacent sides of a kite are equal in length, the diagonal that connects the non-adjacent vertices of the kite divides the kite into two congruent triangles.
