Find the probability of neither showing
multiple of 3 nor multiple of 4 on the second die
Answers
Answer:
the probability of neither showing a multiple of 3 nor a multiple of 4 on the second die is 17/36, or approximately 0.4722
Step-by-step explanation:
To find the probability of neither showing a multiple of 3 nor a multiple of 4 on the second die, we need to first determine the sample space of possible outcomes.
The sample space of rolling two dice is given by all possible pairs of numbers from 1 to 6, which has a total of 6 x 6 = 36 possible outcomes.
Out of these 36 possible outcomes, there are 12 outcomes where the second die shows a multiple of 3 (namely 3, 6, and 9), and 9 outcomes where the second die shows a multiple of 4 (namely 4 and 8).
However, we must note that there are two outcomes where the second die shows both a multiple of 3 and a multiple of 4, namely (3,4) and (6,4). We need to subtract these two outcomes from our total count.
Therefore, the number of outcomes where the second die shows a multiple of 3 or a multiple of 4 or both is 12 + 9 - 2 = 19.
The number of outcomes where the second die does not show a multiple of 3 or a multiple of 4 is the complement of the above count, which is 36 - 19 = 17.
Therefore, the probability of neither showing a multiple of 3 nor a multiple of 4 on the second die is 17/36, or approximately 0.4722.

Answers
Answer:
don't copy this word for word, but here's the answers and reasons you can use
also mark me brainliest if this helps pls
Step-by-step explanation:
Part A:
The area covered by a circle is given by the formula:
A = πr^2
where r is the radius of the circle.
For two-way radio A, the radius is 3 miles. So we have:
A = π(3)^2
A ≈ 28.27 square miles
Therefore, two-way radio A covers approximately 28 square miles.
Part B:
For two-way radio B, the radius is 6.44 kilometers. However, the formula for the area of a circle uses the squared value of the radius, so we need to square 6.44:
A = π(6.44)^2
A ≈ 130.23 square kilometers
Therefore, two-way radio B covers approximately 130 square kilometers.
Part C:
To compare the two areas, we need to convert the area covered by two-way radio A to kilometers:
1 mile = 1.61 kilometers
So 3 miles is equivalent to:
3 miles x 1.61 kilometers/mile = 4.83 kilometers
The area covered by two-way radio A in square kilometers is:
A = π(4.83)^2
A ≈ 73.03 square kilometers
Comparing the areas, we see that two-way radio B covers the larger area.
Part D:
The scale factor relationship between the radio coverages is the ratio of their radii. Using the given conversion factor, we can convert the radius of two-way radio A to kilometers:
3 miles x 1.61 kilometers/mile = 4.83 kilometers
So the scale factor relationship is:
4.83 km (radius of two-way radio A) / 6.44 km (radius of two-way radio B)
= 0.75
This means that the coverage area of two-way radio B is approximately 0.75 times the coverage area of two-way radio A.
Given that A couple of two-way radios were purchased from different stores. Two-way radio A can reach 3 miles in any direction. Two-way radio B can reach 6.44 kilometers in any direction.
A) two way radio A can cover 28 square miles. (using area of circle)
B) two way radio B can cover 132 square kilometer. (using area of circle)
C) Area of coverage of radio B is more.
D) Using the radius of each circle, the scale factor relationship between the radio coverages of A and B is 3:4.
Area of a circle is given by the formula [tex]\pi r^2[/tex].
A) radius of radio A = 3 miles
Area of coverage = [tex]\pi r^2 = 3.14 *3*3 = 28.26[/tex] sq miles
B) radius of radio B = 6.44 km
Area of coverage = [tex]\pi r^2 = 3.14 *6.44*6.44 = 130.22[/tex] sq km
C) 1 mile = 1.61 km
1 sq mile = 1.61 km * 1.61 km = 2.5921 sq km
Area of coverage of radio A = 28.26 sq miles = 28.26 *2.5921 = 73.25 sq km
On comparison, area of coverage of radio B is more.
D) 1 mile = 1.61 km
radius of radio A = 3 * 1.61 = 4.83 km
scalar factor relationship between radio A and B = [tex]\frac{4.83}{6.44} = 3:4[/tex]

Zahra cuts out a rectangle that has a perimeters of 22 inches and a length of 9 inches she cuts another rectangle that is the same length and twice as wide.
Answers
Answer:
The first rectangle that Zahra cuts out has a perimeter of 22 inches and a length of 9 inches. To find the width of this rectangle, we can use the formula for the perimeter of a rectangle:
Perimeter = 2(length + width)
Substituting in the given values, we have:
22 = 2(9 + width)
Simplifying and solving for width, we get:
width = 2 inches
Therefore, the dimensions of the first rectangle are 9 inches by 2 inches.
Zahra then cuts another rectangle that is the same length (9 inches) but twice as wide as the first rectangle. Therefore, the width of this second rectangle is:
2 x 2 inches = 4 inches
So, the dimensions of the second rectangle are 9 inches by 4 inches.
In summary, Zahra has cut out two rectangles with dimensions as follows:
- Rectangle 1: Length = 9 inches, Width = 2 inches
- Rectangle 2: Length = 9 inches, Width = 4 inches

0.8
0.83repeating
1.2
0.67
1.3
1.33
Answers
Answer: To determine which fraction and decimal cards have the same value, we can convert each fraction to a decimal and then compare them to the decimal cards:
2/3 = 0.666... (repeating)
6/8 = 0.75
5/4 = 1.25
5/6 = 0.833... (repeating)
0.6 repeating = 0.666... (repeating)
1.5 = 1.5
0.75 = 0.75
1.3 repeating = 1.333... (repeating)
1.25 = 1.25
0.83 = 0.83
0.8 = 0.8
0.83 repeating = 0.833... (repeating)
1.2 = 1.2
0.67 = 0.67
1.3 = 1.3
1.33 = 1.33
From this list, we can see that Bill can choose the following two cards that have the same value:
2/3 and 0.666... (repeating)
0.6 repeating and 0.666... (repeating)
Step-by-step explanation:
Bill has a range of card pairs that all have the same value at his command. The fraction card 2/3 and the decimal card 0.67 are one such pair because both cards show the value of two-thirds. The fraction card 6/8 (which may be written as 3/4) as well as the decimal card 0.75 are another pair that could be used as both of them reflect the value of three-quarters.
Since both cards show the value of five-sixths, Bill may either select the fraction card 5/6 and the repeating decimal card 0.83 repeating. The fraction card 1.25 and the decimal card 1.25 are another pair that may coexist as both of them represent the sum of one and one-quarter.
Also, Bill has the choice to pick either the fractional card 0.75 or the decimal card 0.75, both of which denote the value of three-fourths. He might also select the decimal card 1.33, which reflects the amount of one and one-third, and the fraction card 1.3 repeating, which is similar to 4/3.
Bill has a choice of card pairs to select from, all of which reflect the same number in both fractional and decimal form.

Answer: B. 70 square units
Step-by-step explanation:
To find the area, we will use this formula :
(A = area, L = length, W = width)
A = LW
We need to find the distance of the length and width, then we will substitute what we know and solve for the area. See attached and below.
A = LW
A = (7)(10)
A = 70 square units
➜ Note that the scale of this coordinate plane is by 2's, not 1's.
70 unit²
Step-by-step explanation:Firstly, we can observe that 1 unit is equal to 2.
So, we can use this formula to find the area of a rectangle.
Area of a rectangle = Length * Breadth
Length of the rectangle = 5 units = 5 * 2 = 10
Breadth of the rectangle = 3.5 units = 3.5 * 2 = 7
Area of the rectangle = 10 * 7
= 70 unit²

Aliya deposits $300 into a college savings account that earns simple interest at a rate of 10%. If she makes no withdrawals, how much total interest has Aliya's college savings account earned after 7 years?
(Include the $ symbol)
Answers
Answer:
after 7 years is $210.
Step-by-step explanation:
To calculate the total interest earned by Aliya's college savings account, we need to use the formula:
I = P * r * t
where I is the total interest earned, P is the principal (initial amount deposited), r is the interest rate (as a decimal), and t is the time (in years).
In this case, Aliya deposited $300, the interest rate is 10% or 0.1, and the time is 7 years. Plugging in these values, we get:
I = $300 * 0.1 * 7 = $210
the total interest earned by Aliya's college savings account after 7 years is $210.

A tart contains either 3 white, or 4 red, or 5 black cherries. A tray of 20 tarts contains 89 cherries. How many red cherries are on the tray if it contains 3 tarts with white cherries?
Answers
- x be the number of tarts with white cherries
- y be the number of tarts with red cherries
- z be the number of tarts with black cherries
From the problem, we know that each tart can only have one type of cherry. So we can set up the following system of equations:
x + y + z = 20 (the total number of tarts is 20)
3x + 4y + 5z = 89 (the total number of cherries is 89)
We also know from the problem that each tart with white cherries contains 3 cherries. So the total number of white cherries is 3x. We are looking for the number of red cherries, which is 4y.
To solve for y, we can use substitution. We can rearrange the first equation to get:
z = 20 - x - y
Then we substitute this expression for z in the second equation:
3x + 4y + 5(20 - x - y) = 89
Simplifying this equation, we get:
2x - y = -3
Now we can solve for y by isolating it on one side of the equation:
y = 2x + 3
We know that each tart with white cherries contains 3 cherries, so the total number of white cherries is 3x. We also know that each tart with black cherries contains 5 cherries, so the total number of black cherries is 5z. So we can rewrite the equation for the total number of cherries as:
3x + 4y + 5(20 - x - y) = 89
Simplifying this equation, we get:
2x - y = -3
Now we can solve for y by isolating it on one side of the equation:
y = 2x + 3
We know that each tart with white cherries contains 3 cherries, so the total number of white cherries is 3x. We also know that each tart with black cherries contains 5 cherries, so the total number of black cherries is 5z. So we can rewrite the equation for the total number of cherries as:
3x + 4y + 5(20 - x - y) = 89
Simplifying this equation, we get:

Daniel opens a new savings account and makes an initial deposit of $1,200. If the account earns 2.5% annual interest, which equation shows how much money is in the account in 9 months?
1. x=1,200+1,200(0.025)(0.75)
2. x=1,200+1,200(0.25)(9)
3. x=1,200+1,200(0.025)(9)
4. x=1,200+1,200(0.25)(0.75)
Answers
Answer:
x = 1,200 + 1,200(0.025)(0.75)
Step-by-step explanation:
The initial deposit of $1,200 is added to the total amount in the account after 9 months, so we start with 1,200 + ?
The annual interest rate is 2.5%, but we need to calculate the interest earned in 9 months. To do this, we can multiply the annual rate by the fraction of the year represented by 9 months, which is 0.75 (9/12). So the interest earned is 1,200(0.025)(0.75).
Adding the interest earned to the initial deposit gives us the total amount in the account after 9 months, which is x.
Answer:
C
Step-by-step explanation:
Seeing has his initial deposit is 1200
We first convert 2.5% to a decimal making it 0.025 because we moved the decimal 2 places back seeing as 100 percent only has 2 0s
It's also asking us how much money is in his account in 9 months meaning we have to times it by 9 and not 0.75
