Answers

Answer:

28

Ward is planning to install a new countertop in his kitchen. The new countertop costs $42.50 per square foot. What will be the cost of the new countertop

Answers

Answer:

$1105

Step-by-step explanation:

The area of the shape is 26 square feet.

This is a composite shape. It is made up of a trapezoid at the top and two identical parallelograms on the sides.

Here are the formulas for the area of each.

Trapezoid:

0.5(2)(6 + 8) = 14

Parallelogram:

2(3) = 6

Now, just add up the 3 parts:

14 + 6 + 6 = 26 sq ft

26 * 42.50 = $1105

A group of 3 friends went to a movie. They paid $15 for a bucket of popcorn. All the
movie tickets were the same price. They paid $51.75 total. Which equation represents
the cost of the tickets?

Answers

Answer:

51.75- 15= 36.75

36.75/3= 12.25 per ticket

Answer:

51.75 - 15 / 3

Step-by-step explanation:

$15 for a bucket of popcorn is separate from the tickets, so you subtract that from the sum.

Then you should have 36.75.

36.75 / 3 = 12.25
