If 2 inches equal 40 miles, 4 inches would equal 80. You don’t have to do anything else because you can eliminate all the other answers. The only one it could be is B. 82.5 miles.
1.
mean=average of all them
(a+b+c+d+e+f+g+h)/8=75
a+b+c+d+e+f+g+h=600
(a+b+c)/3=60
a+b+c=180
subsitute
a+b+c+d+e+f+g+h=600
180+d+e+f+g+h=600
minus 180 both sides
d+e+f+g+h=420
divvide both side by 5
(d+e+f+g+h)/5=84
the mean is 84
2.
1/3 are increased by 6
that means 30 of them are increased by 6
30*6=180
adds 180 to total
180/90=2
increases mean by 2
47+2=49
new mean is 49
c.
v=hpir^2
h=50ft, or 12*50in or 600in
r=1
v=600pi1^2
v=600pi
use 3.14
v=1884 cubic inches
I think it is -8. Subsitute the value. 2(-8) +1=-15 which is less than 0. When you plug -8 for x^2 -1 you get 64-1 which is 63. 63 is offcourse greater than 0.
Answer:
bot 2
Step-by-step explanation:
first find out how many clicks they do in 1 second
16 ÷ 2 = 8
30 ÷ 3 = 10
so know we know that bot 2 clicks 2 more rimes in a second than bot 1
so if we times both the numbers by 10 to find out how many times they click in 10 secs
so bot 1 clicks 80 times
bot 2 clicks 100
Answer:
False
Step-by-step explanation:
The coefficients (numbers in front) don't matter, but the exponents do.
Like terms have exactly the same exponents on the same variables.
are not like terms.
Example: 
<u>are</u> like terms--same exponents on the x's, same exponents on the y's.
