Answer:
d = 4
Step-by-step explanation:
C = 2*pi r or C = pi * d
Area = pi *r^2= pi (d/2)^2 = pi * d^2 /4
So if they are numerically equal, you get
pi * d = pi * d^2 / 4 Divide both sides by pi
d = d^2 / 4 Multiply both sides by 4
4*d = d^2 Divide both sides by d
4 = d
Answer:
1/3
Step-by-step explanation:
4/15 + 1/15 = 5/15
simplified its 1/3
3x² + xy2 – 3xy-y? >> 3x² - xy - y
line 1: = (3x² + xy2)+(-3xy – y?)
ANS 3x² - xy - y 《Correct》
line 2: = x(3x + y2) - y(3x – y2)
ANS 3x² - xy +2y²
line 3: = (x-y) (3x +y?)
ANS 3x² - 2xy - y²
If it incorrect, I'm sorry.
Answer:
The ratio of dogs to animals
.
Step-by-step explanation:
If the shelter captures 9 dogs they also catch 7 cats.
So,
the total number of Animals = Total number of Dogs + Total number of Cats
= 
=
Therefore,
The ratio of dogs to animals = Number of Dogs / Total number of animals
= 
2000+1400+1000+2300+1900=8600, so the answer would be about 8600 miles. Sorry, I couldn't see the picture if that is what it was. I did not see any multiple choices. If you can, comment the choices.
