brian family drinks a gallon of milk in three days how much gallons of milk will brian family drink in five days
Otrada [13]

To calculate this, we have to establish a proportion :

If 1 gallon of milk is drunk in 3 days,​

X gallons will be drunk in 5 days​

X gallons = 1 gallon*5days/3days = 1.66 gallons will drink in 5 days.​

​We can round to the first decimal place 1.66 ≈ 1.7 gallons approximately.

Answer : 1.7 gallons will Brian family drink in five days, approximately.​

​Hope this helps!​​​​

What percent of 92 is 11.5?<br> (this is supposed to be middle school level)
KatRina [158]

Answer: 12.5%

Step-by-step explanation:  

So we can do 11.5/92 with x/100 cross multiply with 100 and 11.5,

11.5 x 100 = 1150

Next we divide 1150 by 92,

1150/92 = 12.5

Therefore we get 11.5/92 = 12.5/100!

What is the total cost of 1.2 Cubic yards of soil if it sells for $24 per cubic yard?
Kaylis [27]

Answer:

$28.80 I hope that helps if not I'm sorry if it's wrong

Step-by-step explanation:

we write "dollars per cubic yard" as "dollars/yd^3" so that the units "yd^3" will cancel when multiplying by "1.2 yd^3", leaving an answer in units of dollars

24 dollars / yd^3 * 1.2 yd^3 = 28.80

the cost would be $28.80
