The correct question is

Ellie made a cube-shaped cardboard box with side-length s. The area of cardboard she used is given by the formula A = 6s2￼, where s represents the side length of the cube.

Which equation correctly solves the formula for s?

we know that

A = 6s²---------> clear the variable s

s²=A/6------> applying square root both members

s=√(A/6)--------> s=(1/6)*√(6*A)

**the answer is**

**s=(1/6)*√(6*A)**

Question

Which situation involves descriptive statistics? A. The survey shows that 1 in 3 moviegoers would attend a midnight showing.
B. A recent survey of the cost of new homes in the United States shows that the median price of a new home is up $15,000 since last year.
C. A reporter surveys some commuters in a city to estimate what percent of city’s commuters spend 45 minutes or more getting to work.
D. Eighty percent of the recipes in a cookbook require salt.

Solution 1

Descriptive statistics give short descriptions of the sample and the measure of the data provided.

Based on this B would be descriptive because it explains the the price of homes is up from last year

Based on this B would be descriptive because it explains the the price of homes is up from last year

Question

92.4 is 150% of what number?

Solution 1

**Answer:**

** Number is 61.6**

**Step-by-step explanation:**

Given : 92.4 is 150%.

To find : what number.

Solution : We have given 92.4 is 150%.

Let the number = x

**According to question :**

**150% of x = 92.4 **

= 92.4

On multiplying both sides by 100

150 x = 92.4 * 100.

150 x = 9240

On dividing both sides by 150 .

x = .

x = 61. 6

**Therefore, Number is 61.6**

Solution 2

1. We assume, that the number 92.4 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 92.4 is 100%, so we can write it down as 92.4=100%.

4. We know, that x is 150% of the output value, so we can write it down as x=150%.

5. Now we have two simple equations:

1) 92.4=100%

2) x=150%

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

92.4/x=100%/150%

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 150% of 92.4

92.4/x=100/150

(92.4/x)*x=(100/150)*x - we multiply both sides of the equation by x

92.4=0.666666666667*x - we divide both sides of the equation by (0.666666666667) to get x

92.4/0.666666666667=x

138.6=x

x=138.6

now we have:

150% of 92.4=138.6

2. We assume, that x is the value we are looking for.

3. If 92.4 is 100%, so we can write it down as 92.4=100%.

4. We know, that x is 150% of the output value, so we can write it down as x=150%.

5. Now we have two simple equations:

1) 92.4=100%

2) x=150%

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

92.4/x=100%/150%

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 150% of 92.4

92.4/x=100/150

(92.4/x)*x=(100/150)*x - we multiply both sides of the equation by x

92.4=0.666666666667*x - we divide both sides of the equation by (0.666666666667) to get x

92.4/0.666666666667=x

138.6=x

x=138.6

now we have:

150% of 92.4=138.6

Question

Solution 1

That would be 152.24 to nearest hundredth

Solution 2

The answer is 152.2.

Question

How many vertices does a convex polyhedron have if it has 14 faces and 24 edges? A) 8
B) 11
C) 12
D) 10

Solution 1

The correct answer is C) 12

Euler's formula states that the number of vertices subtracted by the number of edges and added to the number of faces of a polyhedron always equals 2:

V - E + F = 2

We have 24 edges and 14 faces:

V - 24 + 14 = 2

Combining like terms,

V - 10 = 2

Add 10 to both sides:

V - 10 + 10 = 2 + 10

V = 12

Euler's formula states that the number of vertices subtracted by the number of edges and added to the number of faces of a polyhedron always equals 2:

V - E + F = 2

We have 24 edges and 14 faces:

V - 24 + 14 = 2

Combining like terms,

V - 10 = 2

Add 10 to both sides:

V - 10 + 10 = 2 + 10

V = 12

Question

Solve for A
R=x(A+B)

Solution 1

Use the distributive property

R=Ax+Bx

Ax=R - Bx

A =(R - Bx)/x

The answer is A =(R - Bx)/x

R=Ax+Bx

Ax=R - Bx

A =(R - Bx)/x

The answer is A =(R - Bx)/x
