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

Hello!
In order to find how many boys there are in the class simply subtract 67 from 146:
146-67= 79
There are 79 boys in the class
I hope it helps!

Answer:
The correct option is 3.
Step-by-step explanation:
The HL theorem states that 'if the hypotenuse and one leg of a right triangle are congruent to the hypotenuse and one leg of another right triangle, then the triangles are congruent.'
From the given figure it is noticed that triangle ABC and triangle EDC. In triangle  ABC and triangle EDC, hypotenuses of triangles are AB and DE respectively.
To use HL hypotenuse and one leg of triangles must be equal.
 (hypotenuse)
                             (hypotenuse)
 (leg)
                             (leg)
 (leg)
                              (leg)
Therefore the additional information   will allow you to prove the triangles congruent by the HL Theorem. Option 3 is correct.
