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.

Answer:
Step-by-step explanation: the first is m the second one is 15x+5
Either a student passes an exam or fails it. that means the percentage of students who pass plus the percentage of students who fail must add to 100%. this also means that if 22% pass, then 78% fail. there are 68 students total and 78% fail so the number of students failing is:
(78/100)(68) = 53.04 which is approximately 53 students.
