Answer:

76 quarters and 83 dimes

Step-by-step explanation:

From the information given, you can write the following equations considering that a quarter represents $0.25 and a dime $0.10:

y=x+7 (1)

0.25x+0.10y=27.30 (2)

x is the number of quarters

y is the number of dimes

Now, you can replace (1) in (2):

0.25x+0.10(x+7)=27.30

0.25x+0.10x+0.7=27.30

0.35x=27.30-0.7

0.35x=26.6

x=26.6/0.35

x=76

Then, you can replace the value of x in (1) to find the value of y:

y=76+7

y=83

According to this, the answer is that there are 76 quarters and 83 dimes in the jar.

in the figures below the cube shaped box is 6 inches wide and the rectangular box is 10 inches long 4 inches wide and 4 inches h
IRINA_888 [86]
<span>The cube’s sides measures 6 inches and the measurement for the rectangular box is that it is 10 inches long, 4 inches thick and 4 inches high. To compute for the volume of a cube you must use the formula of V = a3 and for the rectangular prism is V = l x w x h.</span>
<span>Cube:    V = 6^3
</span>              <span>V = 216 inches^3</span>
<span>Rectangular Prism:       V = 10 x 4 x 4</span> <span>             
                                       V = 160 inches^3</span>
To identify how much greater the volume the cube from the rectangular box we subtract their volumes.
N = C – R where N stands for the unknown C for the volume of cube and R for the volume of Rectangular Box <span>
N = 216 inches^3 – 160 inches^3
</span> <span>N = 56 inches^3</span> <span>
So the cube is 56 inches3 greater than the rectangular box.</span>
