Answer:

The answer should be 3 cubic cm

Step-by-step explanation:

First you have to get the area of the right triangle base 1/2 bh. That would be 2x3/2=3

To find volume, you plug the area in the volume formula

v=1/3 ah

v=1/3 (3)(3)

1/3(9) would be 3 cubic cm

I need answers!!!!!!!!

Answer:

a) 4.4583 b) Fiona

Step-by-step explanation:

First find the average of the numbers by adding them all together then dividing them by the amount of numbers given:

$(85 + 88 + 90 + 91 + 93 + 96 + 97 + 97 + 98 + 98 + 99 + 105)\div12= 1137\div12= 94.75$

Then find the difference between each number and the answer you got

$(85 - 94.75) + (88 - 94.75) + (90 - 94.75) + (91 - 94.75) + (93 - 94.75) + (96 - 94.75) + (97 - 94.75) + (97 - 94.75) + (98 - 94.75) + (98 - 94.75) + (99 - 94.75) + (105 - 94.75)\div12$

Which is

$(9.75) + (6.75) + (4.75) + (3.75) + (1.75) + (1.25) + (2.25) + (2.25) + (3.25) + (3.25) + (4.25) + (10.25)\div12$

Which comes out to

$\frac{53.5}{12}=4.4583$

Using words, how do you solve for x? -20 = x + 16

nadya68 [22]

-20 = x + 16.....subtract 16 from both sides
-20 - 16 = x....combine like terms
-36 = x

5(n+4)/3=n-8 A.-24 B.24 C.22 D.-22 PLEASE HELP

arsen [322]

Start with

$\dfrac{5(n+4)}{3} = n-8$

Multiply both sides by 3:

$5(n+4) = 3(n-8)$

Expand both sides:

$5n+20 = 3n-24$

Subtract $3n$ from both sides:

$2n+20 = -24$

Subtract 20 from both sides:

$2n = -44$

Divide both sides by 2:

$n = -22$
