Answer:
It's app. 50.24
Step-by-step explanation:
The area of a circle is A = pi * r ^2

in the question it says to use 3.14 for pi instead
so multiply 16 * 3.14 = 50.24
Answer:
x = 3
Step-by-step explanation:
We need it in factorized form to get x.
If the quadratic equation can be divided by a-2 the first part is:
(a-2)
Now to get a², the a must be multpilied by itself. So
(a-2)(a)
To get -10, -2 must be multiplied by 5. So:
(a-2)(a+5)
we can expand to get x
a² + 5a - 2a -10
a² + 3a - 10
a² + ax - 10
x = 3

Retail Price = $155
Step-by-step explanation:
The retail price is 55% MORE than the manufacturer buying price.
The manufacturer buying price is $100. So the retail price would be 55% MORE.

55/100 = 0.55
Now 55% of 100 is:
0.55 * 100 = $55
So, the retail price is $55 MORE, so the retail price is:
100 + 55 = $155
Retail Price = $155
31/50 is the correct answer. It began at 62/100 but you must reduce
