Answer:306 = 80-q is the answer

**Answer:**

A 5 feet

**Step-by-step explanation:**

divide 100 feet by 20 seconds to find how many feet per second it fell

9514 1404 393

**Answer:**

x = 12

**Step-by-step explanation:**

Sides of similar figures are proportional, so ...

AB/FE = BC/EC

x/6 = 10/5

x = 6·(10/5) . . . multiply by 6

** x = 12**

**Answer:**

**Area=60**

**Step-by-step explanation:**

Area of a triangle:

**A=1/2*h*b**

Substitute:

Height = h = **15**

Base = b = **8**

**A=1/2*8*15**

Solve: **A=60**
