Answer:yes
Step-by-step explanation:
Answer:
$400 dollars in five dollar tickets then $399 dollars in seven dollar tickets.
so you do $400+$399=799
Step-by-step explanation:
You do $400÷5=80 then you do $395R4÷7=55 Then you do 55+80=$135.
so 55 adult tickets and then 80 student tickets.
Mixing the two concentrations would give a new concentration which is in between 50 - 60% .
D. 63% cannot be obtained
Answer:
5/6 is greater
Step-by-step explanation:
Divide each, and change to decimal:
5/6 = ~0.83
1/4 = 0.25
0.83 > 0.25 ∴ 5/6 is greater

Think: (distance traveled by faster car) - (distance traveled by slower car) = 35 mi.
Using the formula distance = rate times time, we get for the faster car:
(55 mph)(t)
and for the slower car we get (50 mph)(t), so that
(55 mph)(t) - (50 mph)(t) = 35 mi. This can be simplified as follows:
(5 mph)(t) = 35 mi. Dividing both sides by 5 mph, we get t = (35 mi) / (5 mph).
Then t = 7 hours. The two cars will be 35 miles apart, going in the same direction, after 7 hours.
