Answer: True
Step-by-step explanation:
The area of a trapezoid is ((b1+b2)/2)*h.
Because this trapezoid is an isosceles trapezoid, we can find the base of the right triangles: 4. Then, using Pythagorean theorem we can get the height of the trapezoid, the square root of 33, or about 5.75. Then plugging the values into the formula, we get 86.25, which is close to 86.2.

The 10 tons should have 37.9% cement.
Let the 25% mixture be x tons
Then the 68% mixture will be (10 -x) tons.
Using formula for mixtures:
Let p for percentage and w for weight in tons.
p₁w₁ + p₂w₂ = pw
25*x + 68*(10-x) = 37.9*10
25x + 680 - 68x = 379
680 - 43x = 379
680 - 379 = 43x
301 = 43x
43x = 301
x = 301/43
x = 7
Recall that x, was for the 25% mixture, 7 tons.
a) For the 68% mixture, = 10 - x = 10 -7 = 3 tons.
b) For the 25% mixture = x = 7 tons.
