You will want to find the area of the whole refuge first. A=b x h. A=650x450. A=292,500. The area of each refuge region is A=25x25. A=625. To find out how many birdhouses you would need you would set up the equation 292,500=625 times x. x=number of bird houses. You would divide 625 from 292,500 getting 468 and that equals x. They will install 468 birdhouses.
Find the length of the diagonal:
1.2 + 1.2 = 2.4 m
Find the length of the other diagonal:
0.9 + 0.9 = 1.8 m
Find area:
2.4 x 1.8 = 4.32 m²
Answer: Area = 4.32 m²
Answer:
the purple on is right
Step-by-step explanation:
Answer:
Only the second one represent a function because the x does not repeat.
For the first and last functions the x is repeating; therefore they are not functions.
Answer:
So the maximum amount of gasoline the tank can contain is 13 gallons and there are already 7 gallons of gasoline in the tank. Therefore, we want to make sure that the amount of gasoline put in the tank doesn't reach any higher than 13 gallon.
The amount of gasoline that Lou bought with x dollars is x/2.50 gallons.
We have the inequality:
x/2.50 + 7 ≤ 13
*If you solve it, x should be smaller or equal to $15.
