8 divided by 12 times 30 = 20.
A quicker way is to realise 12 and 30 are multiples of 6. So you can divide 8 by 2 (4) and multiply by 5 = 20.
Answer:
14449 inches^3
Step-by-step explanation:
length+girth=116 inches
w + 4x= 116
volume=x^2*w
w=116-4x
V=x^2* (116-4x)
for max value, dv/dx=0
dv/dx= 232x-12x^2
232x-12x^2=0
x=19.3333
w=116-4(19.33)
=38.67
V=19.33^2*38.67=14449 inches^3
Answer:
4
Step-by-step explanation:
Answer:
Explanation:
f(x) = 3x+2
g(x) = x^3
(f • g)(x) = (3x+2)(x^3)
(f • g)(x) = 3x^4 + 2x^3
(f • g)(-5) = 3(-5)^4 + 2(-5)^3
(f • g)(-5) = 3(625) + 2(-125)
(f • g)(-5) = 1875 - 250
(f • g)(-5) = 1625
Answer:
80 minutes per 10 miles
Step-by-step explanation:
Because 1 mile is 8 so you first multiply 8 times 10 to get the answer
