Answer:
Alina had at the beginning
cookies
Step-by-step explanation:
we know that
c-----> represent 30% of all the cookies Alina had
Let
x-----> the 100% of all the cookies Alina had
by proportion
![\frac{c}{30\%} =\frac{x}{100\%}\\ \\x=100*c/30\\ \\x=\frac{10}{3}c](https://tex.z-dn.net/?f=%5Cfrac%7Bc%7D%7B30%5C%25%7D%20%3D%5Cfrac%7Bx%7D%7B100%5C%25%7D%5C%5C%20%5C%5Cx%3D100%2Ac%2F30%5C%5C%20%5C%5Cx%3D%5Cfrac%7B10%7D%7B3%7Dc)
Answer:
1.98m
Step-by-step explanation:
First, find the area of the reptile room and the aquarium. A=l*w=72*83=5,976
Second, find the area of ONLY the reptile room. A=l*w. l=72-52=20 w=83-32=51
A=20*51=1,020
Third, find the area of the Amphibian room and the aquarium. A=l*w=72*83=5,976
Fourth, subtract the area of the reptile room from the area of the Amphibian room. 5, 976 - 1,020=4,956=Amphibian room area.
Fifth, add the area of the amphibian room to the area of the reptile room and the aquarium.
4,956+5,976=10,932 ft^2 is the total area of both rooms and the aquarium.
