A.) if 4oz is drank every 4 hours, and there are 24 hours in a day, then there are 6 times during each day that the baby drinks formula. Knowing this, multiply 6 and 4 to get 24oz of formula each day
b.) if 1 can = 91fl oz, and, let's say 30 days in a month, then 24 multiplied by 30 will gives us how much is drank each month which is equal to 720fl oz. Divide 720 by 91 to get approximately 8 cans for one month.
c.) Go back to sub-problem a to find that the new amount per day is now equal to 16oz (6oz/4hrs ... 24/6 = 4 ... 4*4 = 16). Now take 30 and multiply it by 16 to get 480fl oz. Divide 480 by 91 to get approximately 5 cans for one month.
Answer:
the buses are at 50 mph and 60 mph
the distance = 210 miles
Step-by-step explanation:
r1 = rate of bus 1
r2 = rate of bus 2
r1 = r2+10 (The speed of one of the buses was 10 mph greater than the speed of the other bus.)
distance = rate * time
for bus 1
distance = r1 * (3.5)
bus 2 was 1/6 short of making it to town b
so it made it 5/6 of the way
5/6 distance = r2 * (3.5)
multiply by 6/5 on each side
distance = 6/5 * r2 * 3.5
set the distances equal
r1 * (3.5)=6/5 * r2 * 3.5
r1 = 6/5 * r2
now set rate 1 equal (r1 = r2+10)
6/5 * r2 = r2 + 10
solve for r2 by subtracting r2 on each side
6/5 r2 -r2 = 10
6/5 = 1.2
1.2 r2 - r2 =10
.2 r2 = 10
divide by .2 on each side
r2 = 10/.2
r2 = 50
r1 = 50 + 10
r1 =60
to find the distance
distance = r1 * (3.5)
distance = 60 * 3.5
distance = 210 miles
Answer:
IDK if correct but I also think the first
Answer:
Step-by-step explanation:
Given in the number of hours a group of contestants spent preparing for a quiz
The list shows as follows:
60 25 86 56 45 48 90 75 30 67 90 36 80 15 32 65 61
In ascending order this becomes
x 15 25 30 32 36 45 48 56 60 61 65 67 75 80 86 90
F 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 2
Thus we have mode =90
All other entries have frequency 1 except 90
