The perimeter of a rectangle is 88, and the length is 1 less
than 2 times the width. What is the length?
O 29
O24
O 32
O 15
Answer:
29
Step-by-step explanation:
Given:
P = 88
Let's assume, that the length is x and the width is y
x = (2y - 1)
Let's write an equation for the perimeter:
2x + 2y = 88
2 × (2y - 1) + 2y = 88
4y - 2 + 2y = 88
6y = 88 + 2
6y = 90 / : 6
y = 15
We found the width, now we can find the length:
x = 2 × 15 - 1 = 30 - 1 = 29
A bag contains 8 red marbles, 3 blue marbles, and 4 green marbles. What is the probability
. Carlos draws a green marble, does not replace it, and then draws another green marble?
4/15
16/225
54/210
2/35
To solve this problem, we use the rule of conditional probability which states that the probability of the joint event A and B happening is equal to the probability of A happening multiplied by the probability of B happening given that A has already happened.
So, the probability of drawing a green marble on the first draw is 4/15, since there are 4 green marbles out of a total of 15 marbles.
If the first marble drawn is green and not replaced, there are now 14 marbles remaining in the bag, out of which 3 are green.
Thus, the probability of drawing another green marble given that the first one was green is 3/14.
Therefore, the probability of drawing two green marbles without replacement is:
(4/15) * (3/14) = 2/35
So the answer is 2/35.
One leg of a right triangle is twice the length of the other leg. The length of the hypotenuse is √45 centimeters. Let x represent the length of the shorter leg. Use the Pythagorean Theorem to write and solve an equation to find the length of the legs.
Answer:
Let's use the Pythagorean Theorem, which states that in a right triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the lengths of the other two sides.
In this case, we are given that one leg (let's call it the shorter leg) is twice the length of the other leg. So, if we let x represent the length of the shorter leg, then the longer leg has a length of 2x.
We are also given that the length of the hypotenuse is √45 centimeters. We can simplify this by noticing that √45 = √(9 × 5) = √9 × √5 = 3√5. So the length of the hypotenuse is 3√5 centimeters.
Now we can write the Pythagorean Theorem equation:
x^2 + (2x)^2 = (3√5)^2
Simplifying, we get:
x^2 + 4x^2 = 45
5x^2 = 45
x^2 = 9
x = 3
So the shorter leg has a length of 3 centimeters, and the longer leg has a length of 2x = 2(3) = 6 centimeters.

Nyssa made the table below to show the relation between the side length and the areas of various poster boards
The relation between the area (a) and the side length (s) in the table is:
A. a = s²
What is an area?
To see this relationship, we can observe that the areas of the poster boards are the square of their respective side lengths. For example, when the side length is 2 feet, the area is 4 square feet (2²).
Similarly, when the side length is 4 feet, the area is 16 square feet (4²). This pattern holds true for all the side lengths listed in the table. Therefore, we can conclude that the area of each poster board is equal to the square of its side length.
Calculation:
Side Length (s) | Area (a)
1 | 1
2 | 4
3 | 9
4 | 16
As we can see, the area of each poster board is equal to the square of its side length. Thus, the relation between the area (a) and the side length (s) in the table is a = s².

Let ²-13x - 30 = (x+p) (x+q). If the absolute value of p is greater than the absolute
value of q, which number, p or q, is a negative integer? Explain your answer.
Answer: We can use the fact that the sum and product of the roots of a quadratic equation are related to its coefficients, and use this relationship to find the values of p and q.
Given the equation ²-13x - 30 = (x+p)(x+q), we can see that the coefficient of the x^2 term is 1, the coefficient of the x term is -13, and the constant term is -30.
By comparing the coefficients with the formula for the sum and product of the roots of a quadratic equation, we have:
p + q = -(-13)/1 = 13
p*q = -30/1 = -30
Since the absolute value of p is greater than the absolute value of q, we know that either p is positive and q is negative, or p and q are both negative. We can eliminate the possibility of p being positive and q being negative, since their product would be negative, and we know that p*q = -30. Therefore, both p and q must be negative integers.
We also know that the sum of p and q is 13, which means that the absolute value of q is less than the absolute value of p. Since p and q are both negative, this means that q has a larger absolute value (i.e., is farther from zero) than p. Therefore, q is the negative integer in this case.

claims filed under auto insurance policies follow a normal distribution with mean 19,400 and standard deviation 5,000. what is the probability that the average of 25 randomly selected claims exceeds 20,000?
To find the probability that the average of 25 randomly selected claims exceeds 20,000, we need to first determine the mean and standard deviation of the sample distribution.
Given:
- Mean of the population (μ) = 19,400
- Standard deviation of the population (σ) = 5,000
- Sample size (n) = 25
Step 1: Calculate the mean of the sample distribution (μ_sample)
Since the sample mean is an unbiased estimator of the population mean, μ_sample = μ = 19,400.
Step 2: Calculate the standard deviation of the sample distribution (σ_sample)
σ_sample = σ / √n = 5,000 / √25 = 5,000 / 5 = 1,000
Now, we need to find the probability that the sample mean exceeds 20,000. We can do this using the Z-score formula:
Z = (X - μ_sample) / σ_sample
where X is the sample mean we want to find the probability for (20,000 in this case).
Step 3: Calculate the Z-score
Z = (20,000 - 19,400) / 1,000 = 600 / 1,000 = 0.6
Step 4: Find the probability
Now, we need to find the area to the right of the Z-score in the standard normal distribution table or use a calculator/software that provides the probability.
The area to the right of Z = 0.6 is approximately 0.2743. So, the probability that the average of 25 randomly selected claims exceeds 20,000 is approximately 0.2743 or 27.43%.

The surface area of the frustum is approximately 68.49 cm^2 and the volume is approximately 105 cm^3.
How to solveTo calculate the surface area and volume of the frustum of a pyramid, we first need to determine the slant height of the frustum, which we can do using the Pythagorean theorem.
Calculate the slant height of the frustum:
Let s1 and s2 be the side lengths of the top and bottom squares, and h be the height of the frustum.
The slant height (l) can be calculated using the Pythagorean theorem:
l = sqrt(h^2 + ((s2 - s1)/2)^2)
l = sqrt(5^2 + ((6 - 3)/2)^2)
l = sqrt(25 + 1.5^2)
l = sqrt(25 + 2.25)
l = sqrt(27.25)
l ≈ 5.22 cm
Calculate the surface area of the frustum:
Surface area = top square area + bottom square area + lateral surface area
Top square area = s1^2 = 3^2 = 9 cm^2
Bottom square area = s2^2 = 6^2 = 36 cm^2
Lateral surface area = 0.5 * (s1 + s2) * l = 0.5 * (3 + 6) * 5.22 ≈ 23.49 cm^2
Total surface area ≈ 9 + 36 + 23.49 = 68.49 cm^2
Calculate the volume of the frustum:
We can use the following formula to calculate the volume of a frustum:
Volume = (h/3) * (A1 + A2 + sqrt(A1 * A2))
Where A1 and A2 are the areas of the top and bottom squares, respectively:
A1 = 3^2 = 9 cm^2
A2 = 6^2 = 36 cm^2
Volume = (5/3) * (9 + 36 + sqrt(9 * 36))
Volume = (5/3) * (45 + sqrt(324))
Volume = (5/3) * (45 + 18)
Volume = (5/3) * 63
Volume ≈ 105 cm^3
So, the surface area of the frustum is approximately 68.49 cm^2 and the volume is approximately 105 cm^3.

The answer is C) +18 ÷ +3 = +6. Micheal's 50-meter freestyle time was 24.73 meters faster than his 100-meter freestyle time.
What is speed?Measure of how far an object travels in a certain amount of time. Speed is calculated by dividing the distance traveled by the time it took to travel that distance.
The answer is C) +18 ÷ +3 = +6.
This is because Alvin decreased his training by 18 miles over a period of 3 weeks.
Dividing the decrease by the number of weeks gives us 6 miles, which is the average weekly change in his training.
That is 18/3= 6.
To answer the second question, Micheal's 50-meter freestyle was 24.73 meters faster than his 100-meter freestyle.
To calculate this, we subtract the time of the 50-meter freestyle (23.04 seconds) from the time of the 100-meter freestyle (47.77 seconds) to get 24.73 seconds.
We then multiply this time by the speed of a meter per second (1 meter/second) to get 24.73 meters.
Therefore, Micheal's 50-meter freestyle time was 24.73 meters faster than his 100-meter freestyle time.

(round your answer to the nearest tenth of a percent.)
The probability that the married couple will have adjacent desks is 0.72.
Probability means how likely an event is to occur. In many real-life situations, we may have to predict the outcome of events. We may or may not be fully aware of the outcome of the event. In this case, we say it will happen or not. The result often has good applications in sports, business as a result of forecasting, and the result is also widely used in the field of new intelligence.
Mathematically, the number of ways to assign 6 desks to 6 employees is equal to 8!
Now,
the number of ways the couple can interchange their desks is just 2 ways
Thus,
the number of ways to assign desks such that the couple has adjacent desks is 2(6!)
The number of ways to assign desks among all six employees randomly is 7!
Thus, the probability that the couple will have adjacent desks would be ;
2(6!)/7! = 2/7

jane is planning to offer a groupon for inner tube rentals that she will distribute on hot, sunny, summer days by the river that runs through her town. based on her past experience with groupon, she has assigned the following probability distribution to the number of tubes she will rent on a randomly selected day. if jane would like her expected revenue to be at least $390 per day, what should the groupon price be? (round your answer up to the nearest whole dollar amount.)
The price of Groupon for revenue of $300 is $4 if the expected revenue is at least $390 per day.
Probability is assigned as
x =30, 60, 120, 180
P(x) = 0.10,0.40, 0.40, 0.10
Expected sales volume:
Number of tubes x =30, 60, 120, 180
Probability P(x)= 0.10,0.40, 0.40, 0.10
Expected values are 3, 24,48,18
Total = 93 tubes
Groupon price = $390/$93 = $4.19
Jane's price for each Groupon is the daily rental income divided by the expected number of tubes rented per day. The expected number of tubes is derived by multiplying the expected number of each tube by its probability and then summing the results.

Create a real life example that includes function composition in it and solve it?
how can you multiply binomial with a trinomial? Give an example about it and solve it.
For instance: Let f(x) = 2x + 1 and g(x) = x^2. Find (f ∘ g)(3). First, we need to find g(3) which is 3^2 = 9. Then we plug this value into f: f(g(3)) = f(9) = 2(9) + 1 = 19. Therefore, (f ∘ g)(3) = 19.
What is the description of a function composition?Function composition is a mathematical concept that is used to combine two or more functions into a single function. This concept is widely used in real life situations, such as in computer programming, engineering, and physics.
For example, in computer programming, function composition is used to break down complex programs into smaller, more manageable parts. By using function composition, programmers can create complex programs that are easier to read and maintain. Therefore, function composition is a powerful tool that is used in various fields to simplify complex problems and create more accurate models of the world around us.

Suppose a new cross section was created in each solid, both at the same height, using some scale factor k. How would the areas of these 2 cross sections compare? Explain your reasoning.
The areas of the two cross-sections would be proportional to k².
If a new cross-section was created in each solid, both at the same height using a scale factor k, the areas of the two cross sections would be proportional to k².
The reason for this is that when a scale factor is applied to a two-dimensional figure, the area of the resulting figure increases by a factor of k². This is because the linear dimensions of the figure (length and width) are multiplied by k, and since the area is calculated by multiplying length and width, the area of the figure is multiplied by k².
Therefore, if the two cross sections are created at the same height and are scaled by the same factor k, their areas will be proportional to k². For example, if k=2, the area of each cross-section will be four times the original area; if k=3, the area of each cross-section will be nine times the original area, and so on.

Write a proportion comparing the rise to the run for each of the similar slope triangles and find the numeric value.
The proportion of the rise to the run for each of the similar slope triangles is given by:
h / b = mh' / mb' = mh / b
What is proportion?
A proportion is a statement that two ratios or fractions are equal. It is commonly written in the form of two fractions separated by an equal sign, such as a/b = c/d.
To write a proportion comparing the rise to the run for each of the similar slope triangles, we can use the fact that the ratio of corresponding sides of similar triangles is the same.
Let's say we have two similar triangles with corresponding sides of length a, b, and c, and a', b', and c', respectively. Then we can write the following proportion:
a / a' = b / b' = c / c'
Now, let's apply this to finding the proportion of the rise to the run for each of the similar slope triangles.
In a right triangle, the slope is defined as the ratio of the rise (vertical change) to the run (horizontal change). Let's say we have two similar right triangles with slopes m and m', respectively, and the rise and run of the first triangle are h and b, respectively. The rise and run of the second triangle are then mh and mb', respectively.
We can write the proportion of the rise to the run for each triangle as:
h / b = mh' / mb'
Simplifying this proportion, we can cancel out the common factor of b:
h / b = mh' / mb'
h / 1 = mh' / m'
h = bmh'
Therefore, the proportion of the rise to the run for each of the similar slope triangles is given by:
h / b = mh' / mb' = mh / b
The numeric value of this proportion will depend on the specific values of the rise and run for each triangle and the slope of the triangles.

Figure A
123456
Figure B
Answer:
A)
Step-by-step explanation:
just look at the picture.
what must have happened to figure A to turn into figure B ?
is B more to the right or to the left of A ?
well, right. isn't it obvious ?
and when you look at the coordinates of a vertex, it is 3 units to the right of A.
and if the shift to the right had not happened - the 2 figures would be a mirrored image of each other with the x-axis being the mirror.
that is why A) is the right answer.
