Is 7/11 and 42/60 proportional?

Melissa's family is on vacation.they spend $125 per day on food and entertainment.they have a budgeted only up to $750 for food

jeyben [28]

Melissa's family can afford 6 days of vacation.

Reason:

You need to divide the budget by the money they spend everyday.

$750 ÷ $125 = 6 days that the family can afford to pay for vacation.

Hope this helps you!

Algebra one help please?

During the first hour . . .

5% of the 1,000 bacteria die. At the end of the hour, 95% of them are left.

 95% of 1,000 = 950

Then 100 are added : 950 + 100 = 1,050

1,050 bacteria swimming around in the soup as the second hour begins.

During the second hour . . .

5% of the 1,050 bacteria die. At the end of the hour, 95% of them are left.

 95% of 1,050 = 997.5

Then 100 are added : 997.5 + 100 = 1,097.5 . . . . . 1,098 rounded

===================================

Playing with this some more:

If the same process continues, and the result at the end of each hour
is rounded to the nearest whole number, then the number of bacteria
steadily increases, but only for 88 hours. At the end of the 88th hour,
there are 1991 of the little critters, and after that, the population stays
constant at 1991. That's because the 5% loss during each hour after
that is (5% of 1,991) = 99.55 , which rounds to 100, and those are
replaced by the 100 new ones.

You want to put some money in a simple interest account. It pays 6% interest annually for 2 years. You would like to earn $750 i

poizon [28]

Let present value = P
interest rate, i = 0.06
time = 2 years
interest amount = 750
then
750 = Pin = P(0.06*2)
Solve for P
P=750/(0.06*2) = $6250

Answer: $6250 must be deposited to earn the desired interest.

the alexander family and jenkins family each used their sprinklers last summer. the water output rate for the alexander familys

Mumz [18]

Answer:
Alexanders family sprinkler used for 35.25 hours
And the Jenkins family sprinkler was used for 29.75 hours.

Step-by-step explanation:

Lets start with 2 assumptions, what if we only used the Alexander's family sprinklers, We can define X as the variable
$20x=1450$
$x= 72.5$
If we just used the Alexanders it would of took 72 hours and 30 minutes.

Now lets look at the Jenkins family sprinkler, lets define it as Y.
$25y=1450$
$y = 58$
With only the Jenkins it would of took 58 hours.

Now, if they just of shared the work equally among the two sprinklers, the Alexanders family doing 725 L and the Jenkins with the other half.
It would of took the Alexanders
$20x= 725$
$x=36.25$

Jenkins
$25y=725$
$y=29$

Making it a combined time of 65.25 hours. 15 minutes long of our 65 hour time.

Now the Jenkins sprinkler generates 5 more L than Alexanders per hour. Which means it would only take the Jenkins family 1 hours to make 25 liters but Alexanders would take $\frac{5}{4}$ hours. We know that 1 hour contains 60 minutes, which means $\frac{1}{4}$ of a hour contains 15 minutes.

So it would take Alexanders family sprinkler 15 minutes more to produce the same amount per hour that the Jenkins does.

So from this we can conclude that if the Jenkins family sprinkler was used more we can cut the extra 15 minutes off, making the answer That the

Alexanders family sprinkler used for 35.25 hours
And the Jenkins family sprinkler was used for 29.75 hours.
