The diagram shows a row of four identical tiles, each in the shape of an isosceles trapezoid. What is the area of one tile?

The area of one tile is 80 sq.

Step-by-step explanation:

We are given a a row of four identical tiles, each in the shape of an isosceles  trapezoid.

The two isosceles  trapezoid makes a parallelogram

Base of parallelogram =16 inch

Height of parallelogram = 10 inch

Area of parallelogram =

Area of parallelogram =

Area of 2 trapezoid = 160 sq. in.

Area of 1 trapezoid =

Hence the area of one tile is 80 sq.in.

4 times

Step-by-step explanation:

1 quart is equivalent to 32 fluid ounces.

If each eruption consumes 8 fluid ounces of vinegar. Assuming that the amount of vinegar required per eruption is constant, the number of times Tanvi can make her volcano erupt is:

Tanvi can make her volcano erupt 4 times  with 1 quart of vinegar.
