Answer:
300 %
Step-by-step explanation:
Length of the larger cube =4 cm
So volume 
Length of the smaller cube = 1 cm
Volume of the smaller cube 
So total number of smaller cube 
Surface area of the larger cube 
Surface area of the 64 smaller cube 
So percentage increase in surface area
%
Answer:
$38.25
Step-by-step explanation:
Perimeter of a rectangle = 2W + 2L
(where W is the width and L is the length)
Given:
- width = 2.5 yd
- length = 6 yd
⇒ perimeter = (2 x 2.5) + (2 x 6)
= 5 + 12
= 17 yd
Given:
- cost of fence = $2.25 per foot
⇒ total cost = 17 x 2.25
= $38.25
The statement first, and the statement second are correct because the number of dimes is 34, and the number of quarters is 66
What is a linear equation?
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
We have:
0.1x + 0.25y = 19.9 and
x + y = 100
Let x = number of dimes
y = number of quarters
After solving the above system of equations by substitution method.

y = 66

x = 34
Thus, the statement first, and the statement second are correct because the number of dimes is 34, and the number of quarters is 66
