3) You are selling raffle tickets. You sell tickets to adults and children. You sell a
total of 475 tickets. Adult tickets cost $3 per ticket and children tickets cost $2
per ticket. You earn a total of $1200. How many adult tickets and how many
children tickets were sold?
Answer:
Step-by-step explanatiox
x+y = 475
3x + 2y = 1200
3(-y + 475) = 1200
-3y + 1425 = 1200
-3y = -225
y= 75 kids
x = 350

Question 4(Multiple Choice Worth 6 points)
(03.04 LC)
Write the equation of the graph shown below in factored form.
the graph starts at the bottom left and continues up through the x axis at negative two to a maximum around y equals eight and goes back down through the x axis at one to a minimum around y equals negative four and back up through the x axis at three
f(x) = (x + 2)(x − 1)(x − 3)
f(x) = (x − 2)(x + 1)(x + 3)
f(x) = (x + 2)(x + 1)(x + 3)
f(x) = (x − 2)(x − 1)(x − 3)

=================================================
Explanation:
Points R, O, and A are midpoints of sides XY, YG, and XG respectively.
Because of this, we know that the points cut those sides into two equal halves.
To elaborate, we know the following three facts:
Point R is the midpoint of XY, so XR = RYPoint O is the midpoint of YG, so YO = OGPoint A is the midpoint of XG, so XA = AGThe diagram shows that YO = 14, so OG must be 14 units long as well.
The diagram also shows XA = 8. Since XA = AG, we know that AG = 8.
-----------------------------
Use this information to find the perimeter of triangle XYG.
Perimeter of XYG = sum of all the sides
Perimeter of XYG = (XY) + (YG) + (XG)
Perimeter of XYG = (22) + (YO+OG) + (XA+AG)
Perimeter of XYG = 22 + (14+14) + (8+8)
Perimeter of XYG = 66
-----------------------------
Then we cut this in half to get the perimeter of triangle ROA.
We do this because each segment of ROA is half that of the corresponding segment of XYG. The midsegments (RA, RO, AO) are cut in half and are parallel to the opposite side.
So,
Perimeter of ROA = (1/2)*(Perimeter of XYG)
Perimeter of ROA = (1/2)*(66)
Perimeter of ROA = 33

the radius of a circle is 18 in what is the area and circumference
Answer:
324 pi . and 36 pi
Step-by-step explanation:
Area is pi r squared, so 18x18 is 324, times pi which is 324 pi
Circumference is 2 pi r, which is 2 times 18 which is 36, times pi which is 36 pi

Show that the ratios 10 20 and 30 60 form a proportion by finding a common multiplier. Show that the ratios in part (a) are equal by writing them in simplest form. Show that the ratios 10 20 and 30 60 form a proportion by finding a common multiplier. Show that the ratios in part (a) are equal by writing them in simplest form.
Answer:
Common multiplier = 10, Equal simplest forms = 1/2
Step-by-step explanation:
Ratio 10 / 20 & 30 / 60 have common multiplier 10.
As 10, 20, 30, 60 are all multiples of 10.
These ratios are equal, as 10/20 = 30/60 = 1/2 (their simplest form)

Suppose that when a skunk sprays, the odor has a half-life stink potency of
8 hours. This means that the skunks spray would have a stink odor of 100%
when it is first sprayed. Then, after 8 hours, it would smell half as bad (and
be at 50% of its potency). What percent potency would still exist after 1
day? Explain/show your work.
Answer:
12.5% Potency
Step-by-step explanation:
8 x 3 = 24 hours in 1 day so 3 half lifes would progress in 24 hours.
100% Hour 0 Spray (Half Life 0)
50% Hour 8 Spray (Half Life 1)
25% Hour 16 Spray (Half Life 2)
12.5% Hour 24 Spray (Half Life 3)
Answer:
12.5%
