Answer:
Step-by-step explanation:
<h3>Given</h3>
- Price = $79,
- Sales tax = 5%.
<h3>Solution</h3>
Find 5% of $79:
- 79 * 5/100 =
- 395/100 =
- 3.95
By the Pythagorean Theorem, the length of x is
a^2 + b^2 = c^2 Pythagorean Theorem
6^2 + b^2 = 10^2 Substitute known variables
6^2 + b^2 - 10^2 = 0 Subtract 10^2 from each side
6^2 - 10^2 = b^2 Subtract b^2 from each side
√6^2-10^2 = √b^2 Take square root of each side
8 = b Simplify
So, the length of x is 8. I hope this helps!
Answer:
m1=12 and m2=168
Step-by-step explanation:

Answer:
Width = 18 inches
Perimeter = 99 inches
Area = 567 square inches
Step-by-step explanation:
The sides of a rectangle are in the ratio 4:7. Then
Width
in
Length
in.
If its longer side is 31.5 in, then
Length = 31.5 in
and

So,
Width 
The perimeter is

The area is
