Answer:
-q^2 -q + 72
Step-by-step explanation:
(9+ q)(8-q)
=9(8-q)+ q(8-q)
=72 - 9q +8q -q^2
= -q^2 -q + 72
If the family walked 2/5 of a mile in 2/7 of an hour their MPH would be 2.8mph
Step-by-step explanation:
given Tony can type at a constant rate of 110 words every 2 minutes.This means tony can type 55 words in every minute.
A- Tony can type W words in T minutes. W*T=M (M=Minutes Tony typed)
B- Tony can type 1100 words in 20 minutes. as 55*20=1100.
C- Yes, Tony can type the essay. Why: because in this equation w=55 and t=30 minutes so t*w=30*55=1650 so yes, Tony can write the essay.
The value of tan3x must be greater than the value of cos3x, because it is subtractable by a lesser value.
Answer:
188π in^2
Step-by-step explanation:
Surface area of the rocket = surface area of the cone + surface area of the cylinder
Surface area of a cone = πr(r+h^2+r^2)
r = 8/2 = 4 in
4π( 4 + 3^2 + 4^2) =
4π ( 4 + 9 + 16) = 116π in^2
Surface area of a cylinder = 2πrh+2πr^2
(2 x n x 4 x 5) + (2 x n x 16)= 72π in^2
116 + 72 = 188π in^2
