Answer:
Step-by-step explanation:
256^ 3/4
(256)^ 3/4
4,194, 304
10. The constant of proportionality would be 0.07 because in the equation y=kx 0.07 is substituted for k which stands for the constant of proportionality.
11. The equation is t=45d because for every hour you travel 45 miles (or 90/2, 135/3, etc.)
Answer:
Step-by-step explanation:
(a) Option B cost less at 120 miles driven
The cost difference at 120 miles between option A and option B is $15
(b) Option A and B cost the same at driving 60 miles.
Option B would cost more if you drive less than 60 miles.
Answer:
20/3
Step-by-step explanation:
5/k=15/20
5/k=3/4
5 x 4/3 = k
k=20/3
