The answers are as follows:
Box 1) D
Box 2) .02D
Box 3) D + .02D
The formula for an area of a circle is
A=pi times radius squared
there for you do pi times 9.5 to the power of two/squared (radius is half of the diameter so 19 divided by 2 is 9.5)
pi times 9.5 squared
= 283.5
I rounded to the nearest tenths
Answer:
33<x for not being frozen water
Step-by-step explanation:
Answer:
m=10
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
−7(2m−6)+21=−77
(−7)(2m)+(−7)(−6)+21=−77(Distribute)
−14m+42+21=−77
(−14m)+(42+21)=−77(Combine Like Terms)
−14m+63=−77
−14m+63=−77
Step 2: Subtract 63 from both sides.
−14m+63−63=−77−63
−14m=−140
Step 3: Divide both sides by -14.
-14m/-14=-140/-14
m=10
C, I think
