A regular-size box of cereal measures 3 1/2 inches by 8 1/2 inches by 15 inches. The manufacturer also sells an individual-size
Phoenix [80]

The individual-size box of cereal is a rectangular prism with a volume of 44.625 inches³.

<h3>What is the volume of a rectangular prism?</h3>

The volume of rectangular prism of length l, width w and height h is given by:

V = lwh.

In this problem, the standard dimensions are:

  • l = 3(1/2) = 3 + 0.5 = 3.5 inches.
  • w = 8(1/2) = 8 + 0.5 = 8.5 inches.
  • h = 15 inches.

The individual-size box has a 1/10 of the volume of the original box, hence:

V = 0.1 x 3.5 x 8.5 x 15 = 44.625 inches³.

A recipe for trail mix calls for 3/4 cup dried fruits, 1/2 cup mixed nuts, and 1/3 cup granola. How many cups of trail mix does

Hello! I would love to help!

Alright, we need to add all the fractions the problem gives us in order to find the answer. However, first, we need to find a common denominator.


So, what number can 2, 4, and 3 all go into?

The lowest number is 12. So, let's call 12 our common denominator.

Now, let's turn all the fractions to 12 as the denominator.

3/4= 9/12

1/2= 6/12

1/3 =4/12


Okay! Let's add the new fractions!

9/12+6/12+4/12=19/12


Let's turn it into a mixed number!

1 7/12

That's the answer!


Hope this helps! Comment if you have any questions!

Scientific notation 20,000+3,400,000= an example to would be helpful
Viefleur [7K]
20 000 is as much as 20 * 1 000, so we can write it as: 20 * 10^3
3 400 000 is as much as 34 * 100 000, so we can write it as: 34 * 10^5

The sum in scientific notation would look like this:

20 * 10^3 + 34 * 10^5

I hope that's what you meant :)
