Answer:

A) SSS

Step-by-step explanation:

We have,

$\frac{AC}{DF}=\frac{10}{15}=\frac{2}{3}\\\frac{AB}{DE}=\frac{12}{18}=\frac{2}{3}\\\frac{BC}{EF}=\frac{8}{12}=\frac{2}{3}\\\text{Thus,}\\\frac{AC}{DF}=\frac{AB}{DE}=\frac{BC}{EF}\\$

Since the sides are in proportion, the two triangles are similar by the SSS test.

What is the solution to the inequality?

ddd [48]

Solving inequalities is just like solving equations, except you have < or > instead of =, so:
7x + 18 > -3
- 18
7x > -21
÷ 7
x > -3
So your answer is A, x > -3. I hope this helps!

4. The Ferris Wheel Problem:

hoa [83]

Answer: the answer is when the wheel is at 70.43° after 7.82seconds from when you ride on it

Step-by-step explanation:

Rule of 3

65ft center meaning the top point at 90° will be at 115ft since the diameter of the wheel is 50ft

If the 90° gets you at 115ft, at what degree will you reach 90ft?

90°----115ft

X°------90ft

(90x90) ÷ 115 = 70.43°

Then if 360° takes 40seconds which is the complete turn

360°----40s

70.43°--X

(70.43 x 40) ÷ 360 = 7.82s
