Answer: $49.75
Step-by-step explanation:
$53.50 is with the added 7%.
we want to find what the price is without the 7%
take that $53.50 is 100%
1% - 53.50/100 = 0.535
7% - 0.535 x 7 = 3.745
$53.50 - 3.75 = $49.75
9/10 = z/8
cross multiply
9/10(10)(8) = z/8(8)(10)
9(8) = z(10)
72 = 10z
Isolate the z, divide 10 from both sides
72/10 = 10z/10
z = 72/10
z = 7.2
7.2, or D) is your answer
hope this helps

Answer: 20.5
Step-by-step explanation:
From the measure of the length of the sides of the triangle, 9, 40 and 41 we can infer that the triangle is a right angled triangle. 9-40-41 is a Pythagorean triplet.
In a right angled triangle, the circumradius is half the hypotenuse.
In the given triangle, the hypotenuse = 41.
Therefore, the circumradius is 41÷2= 20.5 units.
