There are 9 bicycles and some trictckes at the repair shop. There 42 total wheels on all the bicycles and tricycles. How many tricycles are in the shop

Step-by-step explanation:

No of bicycles = 9

No of bicycle wheels = 9 x 2 = 18

Total wheels = 42

No of wheels remaining = 42 - 18 = 24

Each tricycle has 3 wheels so 24 ÷ 3 = 8

The answer is 8 tricycles

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.
