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:
2 one
Step-by-step explanation:
62+76=138
180-138=42 which is the angle of x
meaning if you substitute 42 in the second equation it will all make sense
42+138=180
Answer:
30 =z
Step-by-step explanation:
-15 = z/-2
Multiply each side by -2 to isolate z
-2 * -15 = z/ -2 * -2
30 =z
Answer:
.25x+1.75=15 and x=53
Step-by-step explanation:
first subtract 1.75 from both sides
then divide by .25 on both sides
and you will get x=53
