100 because a straight line angle is 180
Answer:
<em> (∞, 3]</em>
Step-by-step explanation:
Given the inequality 4x−1<11
We are to find the solution set;
4x−1<11
Add 1 to both sides
4x−1+1<11+1
4x < 12
Divide both sides by 4
4x/4 = 12/4
x < 3
<em>Hence the solution set of the inequality is (∞, 3]</em>
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.
