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

Answer:
Bl^2+4Bl*Fh
Step-by-step explanation:
I'm not quite certain what "draw a net" means here. But for part b, we are doing the formula. The bottom part is a square(assumingly so take this with a grain of salt), thus making the base equal to 3*3 cm or 9 cm^2. The triangular faces are each 3*2.24 cm or 6.72 cm^2. We then multiply this by 4 to get 26.88. Thus, the equation is Bl^2(Base length squared)+Bl*Fh(Face height, I forgot the official name sorry about that)*4 for part b.
ABF= 28 degrees
BCD= 28 degrees since vertical angle are congruent
ABC= 180 -28 = 152 degrees
