Answer:
Step-by-step explanation:
We translate the phrase into an equation:
Then we simplify:
Step-by-step explanation:
1/3πr^2h
{(1/3)×(22/7)×2^2×6}m^3
[(1/3)×(22/7)×4×6)}m^3
{528/21}m^3
=25.1 m^3
NOTE:r=diameter divided by 2
Answer:
The expression 35 - m is used to determine the number of gallons left in the tank after m minutes.Solution:Given that a tank containing 35 gallons of water is leaking at a rate of gallon per minute. Let "m" represent the number of minutes spent Number of gallons left in the tank = initial amount of water present – leaked amount of water
Number of gallons of water left = 35 gallons – number of minutes spent rate of leakage.
Number of gallons of water left = 35 gallons – m minutes 1 gallons per minute Hence, the required expression is 35 – m
C=pid
Since d=9m and pi=3.142, C=3.142*9m=28.278
Rounded to 1 decimal point =28.3
Answer:
8
Step-by-step explanation:
x=pizza
y= breadsticks
3x+2y=30
2x+3y=25
first we myltiply the top equation with 3 and then w emultiply the lower equation with -2 so it is
9x+6y=90
-4x-6y= -50
now we can add them together and the y contracts
5x=40
now we divide it by 5
x=8
So pizza costs 8
