Answer: divide by 100 is .0937
Step-by-step explanation:
The volume of the gallon is 6000 gallon
the rate of water flow per min is f(t)=300t^2
a] amount of water that flowed in the first 7 minutes=7/60 hours will be:
f(7)=300(7/60)^2
solving the above we get
f(7)=7/12 gallons
b] The time taken for the tank to be empty will be as follows:
amount of water that will flow out for the tank to be empty will be 6000 gallons
thus,
6000=300t^2
this can be simplified to
20=t^2
t^2-20=0
solving this we get:
t=-2√5 or 2√5
the time taken for the tank to be empty will be t=2√5 hours=5.4721 hours
The answer is 3y=1+2x
i say this because if the answer ain't telling you to solve for x the you just do this
-2x+3y=1
+2x =1+2x which all u have to do now is drop the positive 3y
which gives you 3y=1+2x
Answer:
D. 1/44
Step-by-step explanation:
divide both sides by the # in front of X - in this case its 6. you should get x= 3/22 ÷ 6 and get your answer there by plugging in the calculator. or on paper-
do 3/22 × 1/6 which is also reduced to --> 1/22 × 1/2 and that is 1/44 but you should be able to jist plug 3/22÷ 6 in if you take middle/highschool math anyways
Answer:
b is the answer it is right I'm sure
