Answer:
$75
Step-by-step explanation:
Answer:
$28.83
Step-by-step explanation:
We will use: and then use cross multiplication.
Let's solve the first sale
We have:
percent = 25%
whole = $200
we want to solve for "part". Lets set the equation up before we plug anything in
now plug everything in:
part = $50
what does this mean?
Well it actually means $50 is the amount of money we take away from our original price of $200.
So we subtract that from our total.
$200 - $50 = $150
Next we will do the second sale.
percent = 50%
whole = $150
Use the same equation as above:
part = $75
Answer:
A
Step-by-step explanation:
Answer:
Volume = 42 units^2
x = 5 units
Total Surface Area = 96 units
Step-by-step explanation:
Volume
V = bh, where b = 1/2 * 3 * 4 and h = 7,
= 6 * 7 = 42 units^2
x
You can solve for this variable by using the pythagorean theorem;
a^2 + b^2 = c^2, where a = 3 and b = 4,
9 + 16 = x^2
= 25 = x^2
= x = 5 units
Total Surface Area
You can solve this by multiplying the perimeter of the base (3 + 4 + 5) by the height and adding that to two times the area of the base:
7 * (3 + 4 + 5) + 2(1/2*3*4)
= 7*12 + 12
= 96 units
