John has a cylindrical propane tank that measures 8" in diameter and 8" tall If John
kirza4 [7]

Answer:

2 times as large

Step-by-step explanation:

For the original cylinder, we can say that the volume of a cylinder is equal to V= πr²h. For this cylinder, we can say that  V = π * radius² * height. The radius is equal to 1/2 of the diameter, so the original radius is 8/2 = 4. Therefore, the volume of the original cylinder is V = π * radius² * height = π * 4² * 8 = π * 16 * 8 = π * 128

For the new cylinder, "twice as wide" means that the diameter is twice as big as the original one. Half the height means that the height is halved. The new diameter is therefore 8 * 2 = 16 (meaning that the new radius is 16/2=8) while the new height is 8/2 = 4. The new volume is thus

V = π * radius² * height = π * 8² * 4 = π * 64 * 4 = π * 256

To see how much larger the new tank volume is, we can divide (new tank volume) by (old tank volume), resulting in

π * 256 / (π *128) = 2

Which expression is equivalent to 1/8x- 1/2?
pychu [463]
This is done by factoring.  1/8 is smaller than 1/2, so we can factor a 1/8 out of 1/2.  This is what that looks like: \frac{ \frac{1}{2} }{ \frac{1}{8} }, because factoring after all is a form of division.  When we divide a fraction by a fraction, we bring the lower fraction up and flip it to multiply, giving us this: \frac{1}{2} * \frac{8}{1}.  This of course reduces to 4.  So when we factor out 1/8, what we will have then is \frac{1}{8} (x-4), choice D from above.

Which value from the set {3,10,90,108} will make the equation 3x + 3 = 33 true ?
Alja [10]

Answer:

x = 10 will make the equation true

Step-by-step explanation:

Given

\{3,10,90,108\}

3x +3= 33

Required

Which is true for x

We have:

3x +3= 33

Collect like terms

3x= 33 - 3

3x= 30

Solve for x

x = 30/3

x = 10

Due soon!! <br>Find the measure of GE¯¯¯¯¯¯¯¯. A. 14 B. 20 C. 15 D. 16
Nataly_w [17]

Answer:

D. 16

Step-by-step explanation:

GH^2 = GF \times GE

12^2 = 9 \times (9+x - 2)

144= 9 \times (7+x)

\frac{144}{9}= (7+x)

16= 7+x

16-7=x

9=x

GE = 9 + x - 2 = 9 + 9 - 2 = 18 - 2

GE = 16
