Nick has $7.00. Bagels cost $0.75 each, and a small container of cream cheese cost $1.29. Write an inequality to find the number
mestny [16]
If you buy 1 container of cream and an unknown number of bagels, x will represent the number of bagels you buy. 
1.29+0.75x<=7.00

I say less than or equal to because you cannot buy more than 7 dollars worth of things.

A retailer buys TV's fro $175 and marks them up 225%, what is the new cost
jonny [76]

Answer:

   $568.75

Step-by-step explanation:

To find the markup, we multiply the original price by the percentage of markup

Markup = 175 * 225%

             =175 * 2.25

              =393.75

The new price is the markup  plus the original price

New price = markup+ original price

                  =393.7+175

                   =568.75

Which of these is the area of a sector of a circle with r = 18”, given that its arc length is 6π?
koban [17]
The formulas for arc length and area of a sector are quite close in their appearance.  The formula for arc length, however, is related to the circumference of a circle while the area of a sector is related to, well, the area! The arc length formula is AL= \frac{ \beta }{360} *2 \pi r.  Notice the "2*pi*r" which is the circumference formula.  The area of a sector is A s= \frac{ \beta }{360}  * \pi r ^{2}.  Notice the "pi*r squared", which of course is the area of a circle.  In our problem we are given the arc length and the radius.  What we do not have that we need to then find the area of a sector of the circle is the measure of the central angle, beta.  Filling in accordingly, 6 \pi = \frac{ \beta }{360} *2 \pi (18).  Simplifying by multiplying by 360 on both sides and then dividing by 36 on both sides gives us that our angle has a measure of 60°.  Now we can use that to find the area of a sector of that same circle.  Again, filling accordingly, A_{s} = \frac{60}{360} * \pi (18) ^{2}, and A_{s} =54 \pi.  When you multiply in the value of pi, you get that your area is 169.65 in squared.
