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

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%

A car travels at a constant speed of 65 mi/hr. How far will it have traveled
in 4 hours?
Answer:
260miles
Step-by-step explanation:
because the car travels 65 miles an hour and it is traveling for 4 hours u have to multiply the miles per hour by 4
Answer:
260 miles
Step-by-step explanation:
if it travels 65 miles/hr, the we would do 65 x 4 to see how far it would travel in 4 hours
I hope this helps, have a great day! :)

=================================================
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

4f – 15s + 16f – 20 + 17 – 12f
Answer:
8f-15s-3
Step-by-step explanation:
Combine the like terms. 4f plus 16f is 20f. 20f minus 12f is 8f. There are no like terms for 15s so it stays. Finally, combine -20 and 17 and you get -3. So the answer is 8f - 15s - 3.
Answer:
8f−15s−3

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)

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)
