Answers

6 is a number that goes into both 18 and 42 if that helps, you can divide 18 by 6 and you get 3, then 42 by 6 and get 7, and that is how you simplify that part. I hope that helped :)

Find the angular velocity in radians per second of a wheel turning at 25 revolutions per minute.

Answers

(25 rev/minute) x (2 pi radian/rev) x ( minute / 60 sec) = 2.618 rad/sec (rounded)

1 revolution= 2π radians= 6,28 radian
1 minute= 60 s
25 rev=50π=157 radian

$(25)/(1)* (6,28)/(60)=2,62 (rad)/(s)$

Help please I give thanks

Answers

1.) Gather all the sides (length, width, and height)
V=l×w×h

2.)Plug in the correct and appropriate volume:
V=8×6× $(1)/(3)$

3.)Multiply all of them:
V=8×6× $(1)/(3)$
=48× $(1)/(3)$
= $(48)/(3)$
=16 (after simplifying)

4.) State the answer in a sentence:

The volume of the rectangular prism is 16 $cubic^(2)$ .

Hope this helps!

Why do fractions need to have a common denominator before you add or subtract them?

Answers

The denominator of a fraction tells you the relative size of thepieces. For instance, 1/2 is bigger than 1/4 because it only takes 2pieces to make a whole, as opposed to 4 pieces to make a whole. Onemight connect the need for a common denominator to the need for havingcommon units before adding or subtracting (you wouldn't add 12 inches to12 feet and get 24 for an answer). Therefore, the reason fractions needa common denominator before adding or subtracting is so that the numberof pieces you are adding/subtracting are all the same size. By the way,the numerator of a fraction just tells you how many pieces you have ofthat size.

Fractions need to have a common denominator because it tells how many pieces the whole is divided into. If one whole is divided into two parts, and another whole the same size is divided in to three parts, one out of the two parts will not be the same size as one out of the three parts.
If we use a common denominator, it ensures each piece is the same size.

if 18 inches is equal to 1 1/2 feet, how many feet long is a 36 inch board? A 72 inch board? A 144 inch board?
