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.
Answer:
Similar but not congruent
Step-by-step explanation:
They look to be the same shape, but they aren't the same exact size so they cant be congruent. To be congruent they would have to be the same size and shape, but they are only the same shape, different sizes.
Answer:
0.0000016
Step-by-step explanation:
(8×10^-3)×(2×10^-4)
=8×10^-3 × 2×10^-4
= (8×2) × (10^-3 × 10^-4)
=16 × 10^(-3) + (-4)
= 16 × 10^ (-3-4)
=16× 10^(-7)
= 0.0000016
