To solve this problem, we use the formula given, which states that SA=6s^2, where SA is the surface area and s is the edge length of the cube.
We were given that the edge length of the cube is 3 1/2 feet, and that we are trying to find the surface area of the cube, so let’s plug these values into our formula.
SA=6(3 1/2)^2
To make this easier to simplify, we are going to replace 3 1/2 with its equal improper fraction, 7/2.
SA=6(7/2)^2
Now, following the order of operations, we are going to simplify what is inside the parenthesis by squaring it.
SA=6(49/4)
Now, we are going to multiply our last two terms together, to get:
SA= 294/4
This number simplifies to 147/2 when we divide both the numerator and denominator by their greatest common factor of 2.
However, the problem asks for your answer as a mixed number in simplest form, which we get when we divide out this improper fraction.
Your final answer is 73 1/2 ft^2.
I hope this helps!
Answer:
$70.34
Step-by-step explanation:
The total before the coupon and tax is:
$54.99 + $21.99 = $76.98
Now apply the 15% coupon:
Since the total price is 100% of the price, when you apply a 15% coupon, you pay 100% - 15% = 85% of the price. We need to find 85% of $76.98
85% * $76.98 =
= 0.85 * $76.98
= $65.43
The price after the 15% coupon, but before the tax, is $65.43
Now the total $65.43 is considered 100% of the price. The tax is 7.5%.
100% + 7.5% = 107.5%
Now we find 107.5% of $65.43
107.5% of $65.43 =
= 1.075 * $65.43
= $70.34
