Answer:
answer b (0.73)
Step-by-step explanation:
"Triple" means to increase in size by a factor of 3.
Thus, B = (1 + r)^2 becomes
3 = (1 + r)^2. Our task is to determine the value of r, the annual interest rate.
Taking the square root of both sides, we get
√3 = 1 + r, which yields √3 - 1 = r.
This is approx. 1.732 - 1.000, or 0.732. Answer b) is closest.
Answer:64
Step-by-step explanation:
You have the other 3 box's with 20 left which is 60 so all you gotta do is 20-16 which is 4
Simplify brackets
10x - 4 = 8x + 14
Add 4 to both sides
10x = 8x + 14 + 4
Simplify 8x + 14 + 4 to 8x + 18
10x = 8x + 18
Subtract 8x from both sides
10x - 8x = 18
Simplify 10x - 8x to 2x
2x = 18
Divide both sides by 2
x = 18/2
Simplify 18/2 to 9
<u>x = 9</u>
Answer:
C
Step-by-step explanation:
y = mx +b The b is where the graph crosses the y axis. If you look a the graph it is crossing at 5. The m is the slope. It is the change in y over the change in x. If you start at 5 and go up10 and over 1, you will be on the line. So our slope is 10/1 which is just 10
