Answer:
Step-by-step explanation:
The formula of the volume of a cube is 
where "a" would correspond to the length of an edge/side/height/etc.
If we insert our value into the formula, we get the following result:

Yes it is equivelant because if u use ditributive property is will give u the same answer
Multiply both sides of the second equation by 100 to get rid of the decimals:
0.05<em>n</em> + 0.10<em>d</em> = 1.50
==> 5<em>n</em> + 10<em>d</em> = 150
Multiply both sides of the first equation by -5:
<em>n</em> + <em>d</em> = 21
==> -5<em>n</em> - 5<em>d</em> = -105
Add the two equations together:
(5<em>n</em> + 10<em>d</em>) + (-5<em>n</em> - 5<em>d</em>) = 150 + (-105)
Notice that the terms containing <em>n</em> get eliminated and we can solve for <em>d</em> :
(5<em>n</em> - 5<em>n</em>) + (10<em>d</em> - 5<em>d</em>) = 150 - 105
5<em>d</em> = 45
<em>d</em> = 45/5 = 9
Plug this into either original equation to solve for <em>n</em>. Doing this with the first equation is easiest:
<em>n</em> + 9 = 21
<em>n</em> = 21 - 9 = 12
So Donna used 12 nickels and 9 dimes.
Answer:
Step-by-step explanation:
Area of parallelogram=base*height
So 1.75*1.5=2.625cm²
There are 8 marks on the line and the first line is 3 long while the second is 2 long
c. 3/8+2/8=5/8
