Pls help! What's the answer?

Answer:

The answer is b = 8a

Step-by-step explanation:

As, 0 x 8 = 0

2 1/2 = 5/2, 5/2 x 8 = 20

5 x 8 = 40

7 1/2 = 15/2, 15/2 x 8 = 60

10 x 8 = 80

13 1/2 = 27/2, 27/2 x 8 = 108

So all variables "a" when multiplied by 8 will give us the value in "b"

So b = 8a

Please help I’ll mark you as brainliest if correct
Alecsey [184]

Answer:

153.94 is your answer.

Step-by-step explanation:

I believe it would be the last one, but let me explain. So to find the area of a circle with just the diameter, the formula would be 1 /4 π d2. Which is one fourth times pie, multiplied with the diameter to the second power. So if we put 14 in the equation would look like this 1/4*π*14*2. So if we use this formula, we get 153.94. Or something close to that. I hope this helps! Good luck!! ;)

Write the equation that describes the following variation. Don't forget "k"!
rosijanka [135]

Answer:

x=(k√x)/(w^2)(cube√z)

x varies directly with square root of y is:

x = k √y

And inversely with the square of w and cube root of s is:

/(w^2)(cube√z)

Now put those together:

x=(k√x)/(w^2)(cube√z)

The formula is:

x=ky/wz but add the specific info like square, roots, or etc

How much heat is released when 12. 0 grams of helium gas condense at 2. 17 K? The latent heat of vaporization of helium is 21 J/
aleksandr82 [10.1K]

The amount of heat released when 12.0g of helium gas condense at 2.17 K is; -250 J

The latent heat of vapourization of a substance is the amount of heat required to effect a change of state of the substance from liquid to gaseous state.

However, since we are required to determine heat released when the helium gas condenses.

The heat of condensation per gram is; -21 J/g.

Therefore, for 12grams, the heat of condensation released is; 12 × -21 = -252 J.

Approximately, -250J.
