Parker just started a running plan where he runs 7 miles the first week and then increases the number of miles he runs by 10% each week. If he keeps up this plan for
15 weeks, how many total miles would Parker have run, to the nearest whole
number?

Parker would have run 29 miles in the 15th week.

Step-by-step explanation:

Since Parker just started a running plan where he runs 7 miles the first week and then increases the number of miles he runs by 10% each week, to determine, if he keeps up this plan for 15 weeks, how many total miles would Parker have run, to the nearest whole number, the following calculation should be performed:

7 x 1.1 ^ 15 = X

7 x 4.1772 = X

29.24 = X

Therefore, Parker would have run 29 miles in the 15th week.

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
