Answer:

  • See below

Step-by-step explanation:

<u>Dimensions given:</u>

  • l = 2 1/4 ft, w = 1 ft, h = 1 1/4 ft

A small cube has side of 1/4 ft

Find the number of small cubes can fit in each dimension of the prism.

<u>Length</u>

  • 2 1/4 : 1/4 = 9/4 * 4 = 9

<u>Width</u>

  • 1 : 1/4 = 1 *4 = 4

<u>Height</u>

  • 1 1/4 : 1/4 = 5/4 * 4 = 5

Part A

<u>Number of small cubes would be:</u>

  • 9*4*5 = 180

Part B

<u>Each small cube has volume:</u>

  • V = (1/4)³ = 1/64 ft³

The volume of the prism in terms of small cubes is 180 as we found above.

<u>The volume in terms of unit cube:</u>

  • V = 180*1/64 = 180/64 = 2 52/64 = 2 13/16 ft³ or 2.8125 ft³

bicycle costs $150. It is advertised on sale for 32% off. What is the cost savings? Solve using two different methods.
alina1380 [7]
The savings is the amount taken off or 32% of 150

32% of 150 is 0.32 times 150=48

savings is $48


or you can do
150/100=x/32
cross multiply to get
x=48


so savings is $48

stira [4]
<h3>Given:</h3>
  • Radius of 50 point region= 3 in
  • Width of other regions= 4 in
<h3>To find:</h3>

The area of the target which earns 30 points on a throw.

<h3>Solution:</h3>

\huge\boxed{Formula: a= \pi{r}^{2}}

4+3

=7

Let's solve

We have to find the answer in terms of π so, we'll just have to multiply the radius by itself.

a={7}^{2}

\large\boxed{a= 49 \pi\: {in}^{2}}

<u>Hence,</u><u> </u><u>the</u><u> </u><u>area</u><u> </u><u>of</u><u> </u><u>the target which earns 30 points on a throw</u><u> </u><u>is</u><u> </u><u>4</u><u>9</u><u>π</u><u> </u><u>square</u><u> </u><u>inches</u><u>.</u>

Find each difference.<br><br> (2x2-5x-7)-(7x2+3)<br><br> PLEASE HELP!!!
Natasha2012 [34]

Answer: -5x^{2} -5x-10

Step-by-step explanation:

(2x^{2} -5x-7)-(7x^{2} +3)  

subtract by terms.

2x^2 - 7x^2 = -5x^2  

-5x  is the only term so leave it alone

-7-3= -10

-5x^2 -5x -10
