I got 71%, by finding out the individual percents and adding them up. Don’t know if that’s how you solve it, but it’s an answer choice, so makes enough sense to me.

Answer:

1st Question

A. 85

2nd Question  

B. 71

Step-by-step explanation:

1st Question

<em>{90 + 94 + 96 + 90} = 370/4 = 92.5</em>

<em>{95 + 99}                  = 194/2 = 97</em>

<em>{87 + 75 + 82 + 85} = 329/4 = 82.25</em>

<em>{71}                =  71/1               = 71</em>

<em>.20(92.5) +.25(97) +.30(82.25) +.25(71) = 85.175  Rounded-up = 85</em>

____________________________________________________

2nd Question

<em>.10(95) +.20(80) +.50(67) +.20(60) = 71</em>

Anyone know this geometry question? Will give brainiest

The opposite angles equal each other, so X and Z are equal
 using that we solve for x by setting them equal:

6x-60 = 2x+68

subtract 2x from each side:

4x -60 = 68

add 60 to each side:

4x = 128
 divide both sides by 4
x = 128/4
x = 32

now we know x so we can solve everything else by replacing x with 32

WY = 3x+5 = 3(32)+5 = 96+5 = 101

angle Z = 2x+68 = 2(32)+68 = 64+132

the answer is C

The volume of a cylinder is 225π cubic inches,
aleksklad [387]

The value of the height of the cylinder is 25cm.

According to the statement

we have to find that the height pf the cylinder with the given value of the volume.

So, For this purpose we know that the

The volume of a cylinder is the density of the cylinder which finds that the amount of material it can carry. Cylinder's volume is given by the formula, πr^2h.

From the given information:

The volume of a cylinder is 225π cubic inches, and the radius of the cylinder is 3 inches.

Then

volume = πr^2h

225π = π3^2h

Now, solve it then

225 = 9h

h = 25.

The value becomes 25.

So, The value of the height of the cylinder is 25cm.
