There are 36 in in a yard

36 in ------> 1 yd


99 in ------> x

x = (99)(1)/36
x = 2.75
 99 inches equals 2.75 yards and that is the amount of trim that Mandy needs to go around the entire quilt

To find the perimeter just add all the sides together. Since it's a square, we can do 99*4. That gives us 396 inches
But wait! They want us to answer in yards. Since there are 3 feet in a yard and 12 inches in a foot, there are 36 inches in a yard. 396/36 is 11, making the answer 11 yards

A population of 1,750 cheetahs decreases by 10% per year. How many cheetahs will there be in the population after 11 years? Roun
Triss [41]

Answer:

The answer is C. 546.

If a population decreases by 11%, that means that 89% (100% - 11% = 89%) of cheetahs remains each number. 89% can be expressed as 0.89, so to calculate the change of the population, we must each year multiply the number of cheetahs by 0.89.

After 1 year:     1750 * 0.89 ≈ 1558

After 2 years:  1558 * 0.89 ≈ 1387

After 3 years:  1387 * 0.89 ≈ 1234

After 4 years:  1234 * 0.89 ≈ 1098

After 5 years:  1098 * 0.89 ≈ 977

After 6 years:  977 * 0.89 ≈ 870

After 7 years:  870 * 0.89 ≈ 774

After 8 years:  774 * 0.89 ≈ 689

After 9 years:  689 * 0.89 ≈ 613

After 10 years:  613 * 0.89 ≈ 546
