Answer:
B
Step-by-step explanation:
Answer:
80 degrees
Step-by-step explanation:
the angles in a triangle all add up to 180 degrees
This situation can be represented by
y = 33x + 223
y = 32x + 239
I still like substitution, so let’s plug in 33x + 223 into the second equation
33x + 223 = 32x + 239
Move the terms into appropriate sides
33x - 32x = 239 - 223
Combine like terms
x = 16
Then plug in x for any equation
y = 32(16) + 239
y = 751
Erin will have to swim 16 laps for a total of 751 meters
Volume
= 1/3 x Area x Height
= 1/3 x 110(Approximately) x 16
≈ 588.8 m^3
Answer is 588.8 m^3.
Hope it helps
Area is equal to the radius^2 • pi. So if you half the diameter and get 6, you then square it and multiply by pi. So your answer is C, 36pi
