The grounds keeper of Estofer Park has to mow 14,623 sq. ft. of grass. He can mow 13 sq. ft of grass in one minute. How many min
MA_775_DIABLO [31]

Answer: 1,124\frac{11}{13}\ minutes

Step-by-step explanation:

Let be "x" the time in minutes that will take him to mow the entire park.

You know that he can mow 13 square feet in 1 minute and he has to mow 14,623 square feet.

Then, you can write the following proportion:

\frac{1}{13}=\frac{x}{14,623}

Solving for "x", you get:

x=\frac{14,623}{13}\ min

To write that improper fraction as a mixed number:

- The quotient when you divide the numerator by the denominator of the fraction obtained, is 1,124 (This will be the whole number).

- The remainder of that division is 11  (This will be the numerator of the fraction).

- The denominator does not change.

Then:

x=1,124\frac{11}{13}\ min

What similarity property, if any, can be used to show that the following two triangles are similar ?
Natalka [10]

Answer:

A) SSS

Step-by-step explanation:

We have,

\frac{AC}{DF}=\frac{10}{15}=\frac{2}{3}\\\frac{AB}{DE}=\frac{12}{18}=\frac{2}{3}\\\frac{BC}{EF}=\frac{8}{12}=\frac{2}{3}\\\text{Thus,}\\\frac{AC}{DF}=\frac{AB}{DE}=\frac{BC}{EF}\\

Since the sides are in proportion, the two triangles are similar by the SSS test.
