It takes 3 1/3 kilometers of thread to make 3 1/2 boxes of shirts. How many kilometers of thread will it take to make 6 boxes?
Julli [10]

Answer:

5 5/7 km

Step-by-step explanation:

We assume the length of thread is proportional to the number of boxes of shirts. If L is the thread length required, then that assumption means

... L/(6 boxes) = (3 1/3 km)/(3 1/2 boxes)

Multiplying the equation by (6 boxes), we get

... L = (3 1/3 km)(6/(3 1/2)) = (10/3 km)(6/(7/2))

... = (10/3 km)(12/7) = 40/7 km = 5 5/7 km

On a loan of $1200 at 15% annual interest, Shirley had to pay $135 interest. For how many months did she have the loan?
natulia [17]

Answer:

<u><em>9 months</em></u>

Step-by-step explanation:

Principal= P= $1200

Rate=R= 15%

Interest= I= $135

Time= T= ?

I=P*R*T/100

135= 1200*15*T/100

135*100=18000*T

13500/18000=T

T= 0.75 years

T= 0.75*12= 9 months
