Nathan does push ups for the same amount everyday. he does 9 minutes of push ups for 3 days. how many minutes of push ups does nathan do in 7 days?

21 minutes

work: okay, so to solve this we need to find the unit rate, or number of minutes he spends doing pushups each day, to be ale to see how many he does in 7 days.

so, to find the unit rate, divide the number of minutes by days.

9/3 = 3

so, this means he spends 3 minutes a day on pushups.

to find out how many he completes in 7 days, multiply how many minutes he spends a day (3) by the number of days (7)

3 x 7 = 21

so, he spends 21 minutes doing pushups in 7 days.

answer: city needs 2.4 inches of rainfall more to match the record of 40 inches.

step-by-step explanation:

since we have given that

total annual rainfall a city record = 40 inches

this year, total rainfall recorded = 37.6 inches

number of inches of rainfall   is needed to match the record of 40 inches is given by

hence, city needs 2.4 inches of rainfall more to match the record of 40 inches.

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
