After staring at this for a few seconds, I think the equation
![-5\sqrt{10}\cdot\sqrt{15}=[1]\sqrt{[2]}](https://tex.z-dn.net/?f=-5%5Csqrt%7B10%7D%5Ccdot%5Csqrt%7B15%7D%3D%5B1%5D%5Csqrt%7B%5B2%5D%7D)
is asking you to simplify the left hand side so that it has a form matching the right hand side, and [1] and [2] are placeholders. My guess is that they're supposed to be integers.
Notice that
Then multiplying by -5, we have
so I believe [1] = -25, and [2] = 6.
Answer:
1. c. 628 cubic cm
2. c. 502 cubic inches
Step-by-step explanation:
1.) 3.14 x 5^2 x 8
3.14 x 25 x 8 = 628
2.) 3.14 x ( 8/2 )^2 x 10
3.14 x 4^2 x 10
3.14 x 16 x 10 = 502.4
Answer:
3 quarts
Step-by-step explanation:
4/1 = 12/3 so 12 cups =3 quarts
Answer:
3
Step-by-step explanation:
When finding the volume of a cube, you would multiply the length x width x height. To find the volume, you would cube the length of one of the sides. For this problem, think of it as working backward because you're starting with the volume but need to know the length of a side. To do the opposite (or inverse) of cubing, you would instead find the cube root of the volume. The cube root of 3,944.312 cubic cm would give you 15.8 cm.
The formula for the volume of a cylinder is <em>v =
. </em>Take the numbers you are given in the problem and put them into the equation to get: <em>v +
. </em>After calculation this equation, you will get an answer of 160.8495. Just round to the nearest tenth to get 160.8.
