Answer:
approximately 11 years
Step-by-step explanation:
Use the compound interest formula:
A = P(1+r)^n, where r is the annual interest rate as a decimal fraction and t is the number of years.
Here we have:
(10000 pounds) = (6500 pounds)(1 + 0.04)^t and must find the value of t.
Solve for (1.04)^t by dividing both sides of this equation by (6500 pounds):
1.5385 = 1.04^t
Take the log of both sides:
log 1.5385 = t*log 1.04, or
log 1.5385
t = -------------------- = (0.1871)/0.0170 = 10.98, or approximately 11 years
log 1.04
The answer is (1,-2). Here’s the work
Answer:
B. 5 inches
Step-by-step explanation:
This is because of the triangle inequality theorem which states "The sum of the lengths of any two sides of a triangle is greater than the length of the third side." So, since 5+9 is 14 it has to be less than 14. Also, because 5+2 is 7 and that is not greater than 9 it has to be 5 inches.
P= 2.5m + 35 (replace p with 115)
115= 2.5m + 35 (subract 35 from each side)
115 - 35 = 2.5m
80 = 2.5m (divide 2.5 from each side)
80/2.5= 2.5m/2.5
32 = m
The price of the materials is $32
