Answer:

D

Step-by-step explanation:

The amount of plastic needed to cover the globe is the surface area of the globe. Since a globe is a sphere, the formula is SA = 4/3 πr³. Substitute r= 3 inches.

SA = 4/3 π(3)³ = 4/3 π * 27 = 36π

Terrence gets a loan with a $50 processing fee. The loan is for $700 with an interest rate of 8% for one
agasfer [191]

Answer:

15.14%

Step-by-step explanation:

The formula for APR is stated thus:

APR=fees+interest/principal/n*365*100

principal is the loan amount of $700

fees is the processing fees on the loan which is $50

interest amount=principal*interest %=$700*8%=$56

n is the number of days of the loan which is a year i.e 365 days

APR=($50+$56)/$700/365*365*100

APR=$106/$700/365*365*100

APR=0.151428571 /365*365*100

APR=0.151428571 *100=15.14%

The annual percentage rate on the loan is 15.14% which represents the actual cost on the loan not just the interest cost of 8% annually

Find the perimeter of squared garden if its area is 1369m2​
irina [24]

Answer:

the perimeter is of 148 m

Step-by-step explanation:

the perimeter is the sum of all sides so an square has all sides equal so we have

P = x+x+x+x = 4x

and the area is

A=x^2=1369m^2

so we find x

\sqrt{x^2}=\sqrt{1369}\\\\x=37

and now the perimeter

P=4x\\\\P=4(37)\\\\P=148
