2/5 of the students at kennedy high are girls. there are 1482 boys in the school. how many student are at kennedy high?

1 answer:

8 0

Let, the number of student = x
Fraction of boys = 1 - 2/5 = 3/5

So, it would be: x * 3/5 = 1482
x = 1482*5 / 3
x = 7410/3
x = 2470

Thus, There are total 2470 students

Hope this helps!

The area of the top face of a cube is 16 square inches. Use 8 of these cubes to make a rectangular

KengaRu [80]

Answer:

The volume of the rectangular prism is 512 inches³

Step-by-step explanation:

Any cube has 6 square faces

Area of any square = L × L, where L is a length of each side

The volume of the cube = L × L × L

∵ The area of the top face of a cube = 16 inches²

→ Find which number multiply by itself = 16

∵ 16 = L × L

∵ 16 = 4 × 4

∴ L = 4 inches

Let us find the volume of 1 cube

∵ The volume of the cube = L × L × L

∵ L = 4 inches

∴ The volume of each cube = 4 × 4 × 4

∴ The volume of each cube = 64 inches³

∵ We will use 8 of this cube to make a rectangular prism

→ That means the volume of the rectangular prism is 8 times

the volume of 1 cube

∴ The volume of the prism = 8 × volume of 1 cube

∵ The volume of each cube = 64 inches³

∴ The volume of the prism = 8 × 64

∴ The volume of the prism = 512 inches³

The volume of the rectangular prism is 512 inches³

isaac has a piece of rope that is 5 yards long. into how many 1/2 yard pieces of rope can isaac cut the rope

marusya05 [52]

What you have to do is figure out how many half inches you need to have to figure out how many half inches equal 5 yards. Therefore if there are 12 inches in a foot, then that would be 24 half inches. So..... three feet equal 1 yards. So multiply 3 by 24. 3x24=72 so you would need 72 half inches

Question is DOWN↓ PLS ANSWER I WILL MARK BRAINLIEST.....

Sonja [21]

Answer: Anita's

Step-by-step explanation:

Anita's shape would have the longest sides because she only has 4 total sides, while the others have 5, 6, and 10

This means that if the total perimeter for each of the shapes was 10 units,

Anita's shape would have side lengths of about 2.5 units while the others would have side lengths of 2, 1.6, and 1 units.

This means Anita's shape has the longest sides

What is the equation, in slope-intercept form, of the line parallel to -5x + y = 2 that passes through the point

larisa [96]

Answer:

y = 5x + 11

Step-by-step explanation:

- first rearrange -5x + y = 2 and you'll have y = 5x + 2

- the slopes of parallel lines are equal so the slope of the line is 5

so far we have y = 5x + b

- to get b, replace the values in the equation by the values of the given point

(1) = 5(-2) + b

- rearrange and calculate, b = 11

y = 5x + 11
