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 minutes will it take him to mow the entire park. give your answer as a mixed number in simplest form.

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:

Solving for "x", you get:

To write that improper fraction as a mixed number:

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

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

- The denominator does not change.

Then:

no, because the sides are not congruent

1gm = 1000mg so 0.1gm = 1000mg

first, convert the weight to kg

160lb * 1kg/2.2lb = 72.7kg

next, the dose

72.7kg * 100mg/kg = 7270mg
