Answer:
9 words per minute
Step-by-step explanation:
Theres 72 words in 8 minutes, so to get her words to minute ratio you do 72 divided by 8 to get 9, words per minute.
Factored form: 2(x^2 + 4x + 3)
Answer:
25*pi or
78.5 square units.
Step-by-step explanation:
If there was no shaded area, the area of the circle would be pi * r^2
r = 10
Area = pi * 10^2
Area = 100 * pi
Since there is a shaded area, the shaded part looks to be 1/4 of the whole. There's no indication of what it actually is, but 1/4 should be close enough.
Area_shade = 1/4 (100*pi)
Area_shade = 25 * pi
That's one answer.
Another is 25 * 3.14 = 78.5 square units
Here is a proportion
5/2 = x/8
2x = 40
/2 /2
x = 20
Hope this helps
Y =1/3x - 1 so slope = 1/3
if <span>perpendicular, slope = -3
passing thru (4,-2) then
y = mx +b
-2=-3(-2) + b
-2=6+b
-2-6 = b
so b = -8
equation:
y = -3x - 8</span>
