Answer: a=x represents sinks
b=the amount of money he will spend overall on the sink and sealent
c= 100x represents 100 sinks
d=joe will have to charge 85 dollars per sink
Step-by-step explanation:
Surface area o fthe ball = 4 * 3.14 * radius^2
if diameter = 1.680 then radius = 1/2 * 1.680 = 0.84
so surface area = 4 * 3.14 * 0.84^2 = 8.862
Consider
.
Given:

To find:
The length of BC.
Solution:
We have,

We know that the corresponding parts of congruent triangles are congruent (CPCTC).
(CPCTC)

The length of BC is 5 m. Therefore, the correct option is A.
We can turn this word problem into the following equation:
x^2 + 85 = (x - 17)^2
x^2 + 85 = x^2 - 34x + 289
-85 -85
_______________________
x^2 = x^2 - 34x + 204
+34x +34x
_______________________
x^2 + 34x = x^2 + 204
-x^2 -x^2
____________________
34x = 204
Divide 34 on both sides
x = 6.
The number is 6.
