A child is hopping along a sidewalk. The ratio table below shows the comparison between the number of hops and the distance traveled. Hopping Number of hops Distance traveled (ft)
20 30
50 75
80 120
120 ? Which statement correctly explains how to find the distance traveled after 120 hops? Subtract 120 – 75 to get 45, then add that number to 120. Add 30 + 75 + 120. 20 multiplied by 6 is 120, so you can multiply 30 times 6 to find the distance. 30 multiplied by 4 is 120, so you can multiply 20 times 4 to find the distance.

c = [tex]\sqrt{45}[/tex]

Step-by-step explanation:

According to the Pythagoras' Theorem, the square of the hypotenuse of a right triangle is equal to the sum of the squares of the two other sides.

Since the other two sides are 6 and 3,  [tex]c^{2}[/tex] = 6 squared + 3 squared.

So, c = the square root of 6 squared + 3 squared

What is the best estimate of the sum of the fractions?

StartFraction 31 over 4 EndFraction + StartFraction 17 over 3 EndFraction + StartFraction 8 over 18 EndFraction

Answers

Answer:

Let's add the fractions first and then we can estimate the sum.

= 31/4 + 17/3 + 8/18

change to common denominators

= 279/36 + 204/36 + 16/36

add numerators only

= 499/36 or 13 31/36 or 13.86

ANSWER: (B) 13 is the best estimate of the answer. Normally we round up to 14 with a number like 13.86, but since that is not a choice, we can estimate 13 as the answer.

Given the similar triangles shown in the diagram below :

A) set up an equation and solve for x

B) find the length of side AB
C ) find the side length of side AC

Answers

Answer:

a.) (x-3)(x-3) = 25 + (x-4)(x-4)

x^2 - 6x + 9 = 25 + x^2 - 8x + 16

-6x + 9 = -8x + 41

2x + 9 = 41

2x = 32

x = 16

b.) 16 - 4 = 12

AB = 12

c.) 16 - 3 = 13

AC = 13

[btw I don't know if this is the method your teacher wants as it does not use the similar triangle :/ but it is still correct :) so good luck bro]
