Please help me with this geometry problem
Natalka [10]
You're looking for the volume of the prism.  The dead giveaway there is that you're looking for "cubic" measurement.  Cubic measures are indicators that the volume is being determined, just like "square feet" or inches, etc indicates area is being determined.  The volume for this prism is found by multiplying the length times the width times the height.  In decimal form, 45×30×40=54,000.  But that is in cubic inches and we want cubic feet.  So we will use dimensional analysis to convert that.  Setting up the DA looks like this, keeping in mind that there are 12 cubic inches in 1 cubic foot:  54,000in^3* \frac{1ft*1ft*1ft}{12in*12in*12in}.  The label of cubic inches cancels out leaving us with cubic feet, and doing the division there gives us 54,000/(12*12*12) which is 31.25 cubic feet.

If a person invested half of her money at 9% and half at 7% and received $160 interest, find the total amount of money invested.
mr Goodwill [35]

Answer:

$2000

Step-by-step explanation:

let x be the money she invested

lets assume this was for 1 year

0.09(x/2) + 0.07(x/2) = 160

multiply each side by 2 to cancel the denominators:

0.09x + 0.07x = 320

0.16x = 320

x = 2000

25 Points!! What is the volume of the prism 1 1/2ft 3 1/2ft 2 1/2 ft? Please answer when you have the time to.
Vladimir79 [104]

Answer:

The first one: 13.125 ft³

The second one: 67.5 ft³

Step-by-step explanation:

For the first one:

The volume of a prism is length x width x height.

So, in this shape, the length is 3 1/2, the width is 2 1/2, and the height is 1 1/2.

However, you can conver 1/2 to .5, to make it easier to multiply.

So, 3.5 x 2.5 x 1.5 = 13.125

Make sure to add ft³, the ft is the unit, feet, and the ³ is used to denote volume, because volume is 3  dimensional.

For the second one, same formula:

Length = 6, width = 2 1/2, and height = 4 1/2

6 x 2.5 x 4.5 = 67.5

Again, make sure to add ft³, the ft is the unit, feet, and the ³ is used to denote volume, because volume is 3 dimensional.
