Answer:

97.6

Step-by-step explanation:

V=πr2h=π·22·8≈100.53096

V≈100.53

V=πr2h

3=π·22·0.7

3≈2.93215

V≈2.93

100.53-2.93= 97.6

Answer:

180.6 cubic inches. (Nearest tenth is the same as 1 decimal place)

Step-by-step explanation:

The volume of a cylinder formula is:

The diameter is

inches, well half of the diameter is

inches which is the radius. Radius is half of the diameter.

If you want the diameter back, just double it.

So we can now plug the numbers into the formula.

)

(

2.3

)

(

)

(

2.3

)

(5 Squared =25)

57.5

But if you didn't want it in terms of

, so you multiply:

57.5

3.14

=180.55

but rounding that to the nearest tenth is the same as rounding to

1 decimal place so you get

180.6 cubic inches.

The slope of the linear equation is 20 and the y-intercept is 150

<h3>What is a Slope?</h3>

Slope measures how steep a straight line is. It is described as rise over run.

The slope of the linear equation can be found as follows;

He opens the account with $150 and he plans to save $20 each week. Therefore,

let

x = number of weeks

Therefore,

y = 20x + 150

where

y = amount in his account after x number of weeks.

Using the slope intercept equation,

<h3>Slope intercept equation:</h3>

y =mx + c

where

m = slope

c = y-intercept

Therefore, the slope of the linear equation is 20 and the y-intercept is 150

Step-by-step explanation:

(k): 65k=c is true if Yutaka was to walk and burn only 48 calories then k then is x= walk and y = run 8x+7y>= c 8x+7y>= 8(48) + 7(65) >= 839

Which expression is equivalent to (x Superscript one-half Baseline y Superscript negative one-fourth Baseline z) Superscript neg

Darina [25.2K]

By using exponent properties, we will get the simplified expression:

$x^{-1}*y^{1/2}*z^2$

<h3>How to simplify the given expression?</h3>

Here we have the expression:

$(x^{1/2}*y^{-1/4}*z)^{-2}$

Remember the exponent properties:

$(a^n)^m = a^{n*m}$

And:

$(a*b)^n = (a^n)*(b^n)$

So using these two properties, we can rewrite:

$(x^{1/2})^{-2}*(y^{-1/4})^{-2}*(z)^{-2}\\\\(x^{-2*1/2})*(y^{-2*-1/4})*(z^{-2}})\\\\x^{-1}*y^{1/2}*z^2$

So we conclude that the completely simplified expression is:

$x^{-1}*y^{1/2}*z^2$
