try using a sphere calculator next time its a lot easier and saves time
Answer:
x = 39
Step-by-step explanation:
We know that PRQ is a right triangle, so we use the pythagorean theorem to solve the problem. The theorem states that a^2 + b^2 = c^2. Let's assume that the length of RP is c, the length of PQ is a and x is b. We plug the lengths into the equation and solve it:
80^2 + x^2 = 89^2
6400 +x^2 = 7921
x^2 = 1521
x = 
x = 39
Yes, that should be correct, I am not to sure so don't take my answer as a full yes, but I think that looks correct.
Your original price would have been $16.23
Explaination:
Take the new markup price and divide it by the percent it was marked up
17.85 / 1.10 = 16.227
1.10 represents 110%
Round your ending number cause there are only two place holders after the decimal for calculating prices. By doing this we change $16.227 to $16.23.
Answer:

Step-by-step explanation:
<u>Area of a rectangle</u>
A rectangle of width W and length L has an area of:
A = W.L
The given rectangle has a length of L=10 inches and a width of W=8 inches, thus its area is:
A = 8*10 = 80

If each corner is cut by a square of x*x, then the total area will be:

The new area is
square inches
