12 feet. if you divide 84 by 7 you get 12. if you want to check your work all you have to do is multiply 7 by 12 and you'll get 84 again.
Answer:
for two lines to be perpendicular m2 = -1/m2
using the formula y= mx+c
m1 = 0
for the lines to be perpendicular to each other(m2 = -1/0 )
Note: -1/0 is undefined
using the formula y-y1 = m(x-x1)
y -6 = -1/0(x-2)
cross multiply
0 = -1(x-2)
0 = -x+2
x =2(equation of the line)
Answer:
B) skirt 1, white
skirt 1, black
skirt 2, white
skirt 2, black
Step-by-step explanation:
You can wear skirt type 1 in white or black, or skirt type 2 in white or black
B) skirt 1, white

skirt 2, black
X + 5
———
3x+2
Steps:
Factor 3x^2 + 13x - 10: (3x -2)(x + 5)
(3x -2)(x+5)
= —————
9x^2 - 4
Factor 9x^2 - 4 (3x - 2)(3x-2)
Assuming that the population follows an exponential function, the it will take the form:
y=a(bˣ)
where:
a=initial value
b=growth factor
x=time
thus plugging our values in the equation we get:
y=40000(1.1ˣ)
thus the population in 2011 when t=3 will be:
y=40000(1.1³)
y=53240
