Ms. Hernandez gave her students a math test

Mathematics
1 answer:
emmainna [20.7K]2 years ago
7 0

Answer:

85-86%

Step-by-step explanation:

Make it an equation

You want to find the percent out of a hundred, so 42 is 100 since it is all of the questions and 36 is the unknown percent X

36/42 = X/100

36             X

42             100

Cross multiply

Do math and solve for X

36 x 100 = 42 x X

3600=42X

X=85.71

A cylindrical tank holds 352 cu. ft. of water. The height of the tank is 7 ft. Find the
Rzqust [24]

Answer:

0.3334 ft

Step-by-step explanation:

Measure the height and radius of the tank. The radius is the distance from the center of the tank to its outer edge. Another way to find the radius is to divide the diameter, or width, by two. Square the radius by multiplying the radius times itself and then multiply it by 3.1416, which is the constant pi.

  1. Given height and volume: r = √(V / (π * h)),
  2. Given height and lateral area: r = A_l / (2 * π * h),
  3. Given height and total area: r = (√(h² + 2 * A / π) - h) / 2,
  4. Given height and diagonal: r = √(h² + d²) / 2,
  5. Given height and surface-area-to-volume ratio: r = 2 * h / (h * SA:V - 2),
  6. Given volume and lateral area: r = 2 * V / A_l,
  7. Given base area: r = √(A_b / (2 * π)),
  8. Given lateral area and total area: r = √((A - A_l) / (2 * π)).
