Answer:

x = 4
y ≈ 10.8

Step-by-step explanation:

In this geometry, the triangles are similar. That means corresponding sides are proportional:

short side/long side = x/10 = 10/25

x = 100/25 = 4 . . . . multiply by 10

hypotenuse/short side = y/x = (x+25)/y

y² = 4(29) = 116 . . . . . use 4 for x; cross multiply

y = √116 ≈ 10.8

Answer:

A. y = 3x; 30 feet

Step-by-step explanation:

The person travels 75 feet in 25 seconds, meaning that he will travel 3 feet per second.

75/25 = 3

This means that the equation will be y = 3x. To find the the feet traveled after 10 seconds, plug 10 into the given equation and solve for y.

y = 3x

y = 3(10)

y = 30

The person will travel 30 feet.

Paul [167]

Given:

Jerome ate 1/2 of the sandwich , Kevin ate 1/3 of the sandwich, and Seth ate the rest.

To find:

The ratio of jerome's share to kevin's share to seth's share.

Solution:

Jerome ate 1/2 of the sandwich. So,

Jerome's share = $\dfrac{1}{2}$

Kevin ate 1/3 of the sandwich. So,

Kevin's share = $\dfrac{1}{3}$

Seth ate the rest. So,

Seth's share = $1-\dfrac{1}{2}-\dfrac{1}{3}$

= $\dfrac{6-3-2}{6}$

= $\dfrac{1}{6}$

The ratio of jerome's share to kevin's share to seth's share is:

$\dfrac{1}{2}:\dfrac{1}{3}:\dfrac{1}{6}$

To simplify the ratio multiply the ratio by 6.

$\dfrac{1}{2}\times 6:\dfrac{1}{3}\times 6:\dfrac{1}{6}\times 6$

$3:2:1$

Therefore, the ratio of jerome's share to kevin's share to seth's share is 3:2:1.
