a duck travels from point A to point B. if the duckj flies 3/4 of the way, walks 1/9 of the way, and swims the remaining 10 kilometers of her trip, what is the total distance in kilometers traveled by the duck

Step-by-step explanation:

Given

Required

Determine the total distance travelled

First, we need to calculate the fraction of the distance where the duck swim, using the following equation:

Collect Like Terms

Take L.C.M

This means that the duck swim 5/36 of the journey.

So, we have:

Multiply through by

Hence, the duck travelled 72km

the 3rd option is right

step-by-step explanation:

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.
