Answer:
6/5 hours
Step-by-step explanation:
GIVEN :-
Lets say ,
Pump A takes 2 hours to fill the tank alonePump B takes 3 hours to fill the tank aloneTO FIND :-
Time taken by both pumps to fill the tank when used togetherPROCEDURE :-
In 2 hours , Pump A fills the whole tank.
⇒ In 1 hour , Pump A will fill 1/2 part of tank. (By using Unitary method)
In 3 hours , Pump B fills the whole tank.
⇒ In 1 hour , Pump B will fill 1/3 part of tank. (By using Unitary method)
In 1 hour , when both pumps will be used together , they will fill =
(Part of tank filled by A in 1hr) + (Part of tank filled by B in 1hr)
⇒ [tex]\frac{1}{2} + \frac{1}{3}[/tex]
[tex]=> \frac{5}{6}[/tex] part of tank
5/6 part of tank will be filled by both the pumps in = 1 hour.
Using unitary method, multiplying both the sides with 6/5 -
⇒ 5/6 × 6/5 part of tank will be filled by both the pumps in = 1 × 6/5 hours
⇒ Total tank (or 1 whole tank) will be filled by both the pumps in = 6/5 hours
∴ Both the pumps will take 6/5 hour to fill the tank , when used together.
A company sells widgets. The amount of profit, y, made by the company, is related to the selling price of each widget, x, by the given equation. Using this equation, find out what price the widgets should be sold for, to the nearest cent, for the company to make the maximum profit.
y = -x^2 + 99x - 932
Answer:
$49.5
Step-by-step explanation:
y = -x^2 + 99x - 932
The maximum point is :
dy/dx = 0
Take the first derivative of y
dy/dx = - 2x + 99
Put - 2x + 99 = 0
-2x = - 99
x = 99 / 2
x = 49.5
Hence, To make maximum profit, widget should be sold at $49.5 per widget.

SARAH makes $43,000 per year, is single, and lives in Connecticut. She has $19,000 in subsidized loans and $8000 in unsubsidized loans.
Answer:
The standard repayment plan.
Step-by-step explanation:
Here is the complete question :
SARAH makes $43,000 per year, is single, and lives in Connecticut. She has $19,000 in subsidized loans and $8000 in unsubsidized loans. Which repayment plan will be the cheapest for her in total?
The standard repayment plan is a repayment plan where a fixed sum is paid monthly for 10 years. This makes a total of 120 payments. The advantage of the standard repayment plan over the federal repayment plan is that less interest is paid and payment is made over a shorter period
Because unsubsidized loans accrue a higher interest expense when compared to subsidized loans, Sarah should pay off her unsubsidized loan first. This would minimise interest payment

Step-by-step explanation:
Find the length of the rectangle.
A. 10 in.
B. 20 in.
C. 27 in.
D 70 in.
Answer:
length = 10 inches
Step-by-step explanation:
We know that the perimeter of a rectangle:
P = 2(L + W), where p= perimeter, L = length, W= width, so:
34 = 2(L + 7)
=> 34 = 2L + 14
=> 20 = 2L
=> 20/2 = L
=> 10 = L

Calebs puppy weighs 2250 grams. If the puppy weighed 600 grams at his last visit to the vet, what is the percent increase in the puppies weight
Answer:
275%
Step-by-step explanation:
Given that,
Initial weight of the puppy = 600 grams
Final weight of the puppy = 2250 gram
We need to find the percent increase in the puppy's weight.
Increase in weight = 2250 gram - 600 grams
= 1650 grams
The percentage of increase in weight,
[tex]\%=\dfrac{1650}{600}\times 100\\\\=275\%[/tex]
So, the required increase in puppy's weight is equal to 275%.

A store sells gas and containers. One customer buys 2 containers and 8 gallons of gas for $38.06. Another customer
buys 1 container and 3 gallons of gas for $15.76.
Enter the price ,in dollars, of 1 container
Answer:
$5.95
Step-by-step explanation:
Given :
Let containers = c ;Gallon of gas = g
2c + 8g = 38.06 - - - (1)
c + 3g = 15.76 - - - - (2)
From (2) :
c = 15.76 - 3g
2(15.76 - 3g) + 8g = 38.06
31.52 - 6g + 8g = 38.06
2g = 6.54
g = 6.54 / 2
g = 3.27
Recall :
c = 15.76 - 3g
c = 15.76 - 3(3.27)
c = 5.95
