Two researchers are studying the decline of orangutan populations. In one study, a population of 784 orangutans is expected to d

ecrease at a rate of 25 orangutans per year. In a second study, the population of a group of 817 orangutans is expected to decrease at a rate of 36 per year. After how many years will the two populations be the same?

Let X be the number of years
784-25x.....equation A
817-36x.....equation B

Equation A=Equation B
784-25x=817-36x
Move terms
36x-25x=817-784
Solve for x
11x=33
Divide both sides by 11
X=33/11
X=3 years

Hope it helps!

8^x times 2^(4-x) = 1<br> Find x.<br> With detailed steps.
Dafna1 [17]

Answer: x= -1

Step-by-step explanation:

In mathematics when you have bases that are the same while multiplying you add the powers. In this case we do not have the same bases so we are going to make it look like 8 is 2. So we sort of simplify it. So we get 8 and put into like 2^4. We do not eliminate the power x that was already there though. So we will have 2^4x × 2^4-x. So like I said earlier we add the powers. Soo we will have

  1. 4x +4-x
  2. 4x-x=1
  3. 3x+4-4 =1-4
  4. 3x/3 = -3/3
  5. x= -1

This drawing shows an Isosceles triangle. Work out the size of angle a. ​
antiseptic1488 [7]
50 degrees

All triangles have 180 degrees total.

Since it’s an isosceles triangle, the 2 bottom angles are congruent; thus, they have the same angle measurement.

Now just subtract the two angles from 180 to get the third angle.

180 - 65 - 65 = 50
