Answer:

4,050 cubic feet

Step-by-step explanation:

Split into a cube and a pyramid, calculate volume of each, then add together for total volume.

Volume of a cube is V=lwh

Volume of a pyramid is V=

$\frac{lwh}{3}$

so cube first...

15×15×15=3,375

now pyramid...

15×15×9=2,025

2,025/3=675

Now add both together for total volume...

3,375+675=4,050

2 5/7 as a decimal. How do you figure out?

weqwewe [10]

2 5/7 as a decimal is approximately 2.70

We know that the ones place will be a two. That doesn’t change when you convert. Next you need to divide 100 by 7, which equals 14. Then you need to do 14 times 5, which equals 70. So, now you know the values after the decimal point (.70). Combine that with the whole number 2 to get 2.70.

I need this to be simplified

umka2103 [35]

Answer:

$\frac{x+2}{3x-1}$

Explanation:

→ $\frac{(x^2-9)(x+2)}{(3x^2 +8x -3)(x-3)}$

→ $\frac{\left(x+3\right)\left(x-3\right)\left(x+2\right)}{\left(3x^2+8x-3\right)\left(x-3\right)}$

→ $\frac{\left(x+3\right)\left(x+2\right)}{3x^2+8x-3}$

→ $\frac{\left(x+3\right)\left(x+2\right)}{\left(3x-1\right)\left(x+3\right)}$

→ $\frac{x+2}{3x-1}$

PLEASE HELP MEeeeeee D:

pav-90 [236]

Okay so i’m not 100% but i think it’s 37 is the first number then it’s 37/9 x 9/2 which is 18.5 or 18 1/2

but you find it by first doing 4x9 and adding the 1 and then you do keep change flip when dividing fractions and solve it out so i think that’s how you do it :)
