Which quantity is proportional to 65⁄5? check all that are true. 13⁄1 260⁄10 195⁄15 130⁄15 130⁄10

Step-by-step explanation:

we have the ratio

step 1

Divide both sides (numerator and denominator) by 5

therefore

is proportional to

step 2

Multiply both sides (numerator and denominator) by 3

therefore

is proportional to

step 3

Multiply both sides (numerator and denominator) by 2

therefore

is proportional to

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)

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.
