Answer:
10) x=90
9) x=20
Step-by-step explanation:
x+2x=180
3x=180
divide 180 by 3x=90
straight lines add up to 180 degrees.
9) x+8x=180
9x=180, thus 20.
Answer:
V = Π (4)2*12
V = 603.19 cm3
Step-by-step explanation:
A soup can is a cylinder.
The formula for volume of a cylinder is the following: V= Πr2h.
We are given the height which is 12 (h=12) and the diameter which is 8 (d=8).
The formula asks for radius so we divide the diameter by 2.
r =8/2 = 4.
Now we can just plug the numbers into the formula
V = Π (4)2*12
V = 603.19 cm3
Since the units of measure are in centimeters, the volume will be measured in cubic centimeters.
The easiest way to compare fraction is to make them all have the same denominator and then you can just compare the numerators...
-1/6, (5/3)(2/2), -5/6
-1/6, 10/6, -5/6 so from least to greatest
-5/6, -1/6, 10/6
-5/6, -1/6, 5/3
You round 4020 to 4000
round 16 to 20
then divide 4000 by 20
once you divide the answer is 200
