Answer:

Step-by-step explanation:

If the radius, r, is given, then the area of the circle is A = πr².

If the diameter, d, is given, then the circle area is A = π(d/2)², or A = πd² / 4.

marysya [2.9K]
First you must combine like terms, the two terms I this expression are x, and xy. So by adding -2xy to -2xy you get -4xy. Next you must add 3x to 3x. This gives you the simplified expression -4xy+6x. Hope this helps

If m angle abf=7b-24 and m angle abe=2b find m angle ebf
cricket20 [7]

angle ABE is equivalent to the whole angle, and it measures 2b. <span>
while the angle ABF is only a portion of angle ABE, and it measure 7b - 24. 

<span>since we know the measure of the whole angle and a part of the angle, we can then subtract to find the left over angle (angle EBF), so

Angle EBF = Angle ABE - Angle ABF </span></span>

Angle EBF = 2b – (7b – 24)

<span>Angle EBF = 24 – 5b</span>

We have $8.50 an hour gross minus $2.15 an hour tax and bennys.  Then $3.75 daily expense.  In one week our net take-away y after x hours is

y = x(8.50 - 2.15) - 5(3.75)

That's the answer, or we can simplify it to

Answer: y = 6.35 x - 18.75

Answer: The slope, 6.35, is the net dollars per hour <em>before weekly expenses.</em>

Answer: The y intercept, -18.75, is the weekly expense, negative because it's an expense.

To make $120 in a week, we solve for x where y=120

120 = 6.35x - 18.75

138.75 = 6.35 x

x = 138.75 / 6.35 = 21.8503937007874

That wasn't the nice round number I was expecting/hoping for.  I don't see a mistake so let's go with

Answer: 21.85 hours to make $120
