Answer:
$67.50
Step-by-step explanation:
To find the new price of the sneaker, you would multiply 54.00 by 1.25. (it's 1.25 because to do percents you would divide them by 100 to put them in decimal form.)
Answer:
5 inches
Step-by-step explanation:
Since the length of the sides of a cube are all equal,
volume of cube
= side ×side ×side
= (side)³
125= (length of side)³
Cube root both sides:
Length of each edge
![= \sqrt[3]{125}](https://tex.z-dn.net/?f=%20%3D%20%20%5Csqrt%5B3%5D%7B125%7D%20)
= 5 inches
Answer:
S(x) = x² + 390224/x
Step-by-step explanation:
Volume of the open box = V = 97556 cm³
Material needed:
Let´s call x the side of the square base then the area of the base is
A(b) = x²
For the sides of the box, we have 4 sides each one with area of x*h
where h is the height of the box
The volume of the box V(b) = 97556 = x²*h then h = 97556/x²
S(x,h) = x² + 4*x*h*
The surface area of the box as function of x is:
S(x) = x² + 4*x*97556/x²
S(x) = x² + 390224/x
divide the amount added to the price by the amount the item costs you to buy to find the markup rate expressed as a decimal.
mark up% = selling price - cost/cost • 100
