Manita's computer installed the software 48 minutes before than Humi's computer.
What is unit rate?A unit rate means a rate for one of something.
Given that, Manita's computer takes 3 minutes to download a program 15% and Humi's computer install it in 68 minutes 100%.
Manita's computer;-
15% in 3 min
1% in 1/5 minutes
100% in 1/5x100 = 20 minutes.
Whereas, Humi's computer took 68 minutes to install the same program.
This mean, Manita's computer was faster than Humi's.
68-20 = 48
Hence, Manita's computer installed the software 48 minutes before than Humi's computer.

You decide to buy a refurbished computer for $550.00 plus 6% sales tax. BB Electronics allow you to take out a no-interest loan for 12 months, and after that the interest rate is a 13.25% APR. You must make payments of $25/month, and if you miss one payment you are assessed a late fee of $29.00 plus 13.25% APR interest beginning from the date of purchase.
You missed the second payment. What is the amount of interest of the bill you will receive?
The interest on the bill will be calculated as follows:
Amount of Loan = $550
Sales Tax = 6% of $550 = $33
Total Loan = $550 + $33 = $583
Interest = 13.25% APR x $583 = $77.13
Late fee = $29
Total Interest = $77.13 + $29 = $106.13

Find the quadratic equation whose parabola has vertex (3, –2) and y-intercept (0, 16). Give your answer in vertex form, and show your work.
Please Help!!
Answer:
y = 2(x-3)^2-2
Step-by-step explanation:
We can find the quadratic equation by using the vertex form. The vertex form of a quadratic equation is:
[tex]y=a(x-h)^2+k[/tex], where x and y are any point on the parabola, a is the constant (indicating whether the parabola opens up or down), and h and k are the coordinates of the vertex.
Since we already have the y-int (an x and y coordinate lying on the parabola) and the vertex, we can plug in both to find a:
[tex]16=a(0-3)^2-2\\16=a(-3)^2-2\\16=9a-2\\18=9a\\2=a[/tex]
Thus, the equation is:

You withdraw $375 from your bank account. You receive a stack of 24 bills consisting of $5, $10, and $20 bills. The number of $5 bills is one-half the number of $10 bills. How many of each type of bill do you receive?
The number of $ 5 bills = 3
The number of $ 10 bills = 6
The number of $ 20 bills = 15
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the total amount be = $ 375
Let the total number of bills = 24
Let the number of $ 5 bills be = x
Let the number of $ 10 bills be = y
Let the number of $ 20 bills be = z
The total number of $ 5 bills x = ( 1/2 ) x number of $ 10 bills
So , x = y/2
Now , the equation will be
The total number of bills = x + y + z
So , x + y + z = 24 be equation (1)
And ,
The total amount = 5x + 10y + 20z
So , 5x + 10y + 20z = 375
Divide by 5 on both sides , we get
x + 2y + 4z = 75 be equation (2)
On simplifying equation (1) and equation (2) , we get
x + y + z = 24
Substituting the value of y , we get
x + 2x + z = 24
3x + z = 24 be equation (3)
And ,
x + 2y + 4z = 75
x + 4x + 4z = 75
5x + 4z = 75 be equation (4)
Multiply equation (3) with 4 , we get
12x + 4z = 96 be equation (5)
Subtract equation (4) from equation (5) , we get
7x = 21
Divide by 7 on both sides , we get
x = 3
Therefore , the number of $ 5 bills is 3
Substitute the value of x , we get
y = 2x
y = 6
Therefore , the number of $ 10 bills is 6
Substitute the value for x and y in equation (1) , we get
x + y + z = 24
3 + 6 + z = 24
z + 9 = 24
Subtract 9 on both sides , we get
z = 15
Therefore , the number of $ 20 bills is 15
Hence ,
The number of $ 5 bills = 3
The number of $ 10 bills = 6
The number of $ 20 bills = 15

On Saturday, the Milleman Family had dinner at a restaurant. They ordered 3 pizzas and 2 cheeseburgers for $41.50. The following weekend, the Anderson Family had dinner at the same restaurant where they ordered 2 pizzas and 5 cheeseburgers for $43.25. Which system of equations can be used to determine the cost of one pizza (p) and one cheeseburger (c)?
Answer: $8.64 and $7.79 respectively.
Step-by-step explanation: To determine the cost of one pizza and one cheeseburger, we can set up the following system of equations:
3p + 2c = 41.50
2p + 5c = 43.25
The first equation represents the total cost of the Milleman Family's meal, where 3p represents the cost of 3 pizzas, 2c represents the cost of 2 cheeseburgers, and 41.50 represents the total cost of the meal. The second equation represents the total cost of the Anderson Family's meal, where 2p represents the cost of 2 pizzas, 5c represents the cost of 5 cheeseburgers, and 43.25 represents the total cost of the meal.
By solving this system of equations, we can determine the cost of one pizza and one cheeseburger. For example, we can use the elimination method to solve the system of equations as follows:
First, we can multiply the first equation by 5 and the second equation by 3 to get the following equations:
15p + 10c = 207.50
6p + 15c = 129.75
Next, we can subtract the second equation from the first equation to eliminate the c terms and find the value of p as follows:
15p + 10c = 207.50
6p + 15c = 129.75
9p = 207.50 - 129.75
9p = 77.75
p = 77.75 / 9
p = 8.64
Finally, we can substitute the value of p that we found into one of the original equations to find the value of c as follows:
3p + 2c = 41.50
3(8.64) + 2c = 41.50
25.92 + 2c = 41.50
2c = 41.50 - 25.92
2c = 15.58
c = 15.58 / 2
c = 7.79
Therefore, the cost of one pizza is $8.64 and the cost of one cheeseburger is $7.79.

How to solve the double integral?The double integral is solved in two steps, first the inner integral is solved, and then the result of the inner integral is used to calculate the outer integral.
Considering the function and the region, the complete integral in this problem is given as follows:
[tex]\int_{-4}^{2}\int_{-4}^{2} (3x + y)dxdy[/tex]
Then the inner integral in this problem is given as follows:
[tex]I = \int_{-4}^{2} (3x + y)dx[/tex]
We are integrating the variable x, then the variable y is a constant, as thus the result is given as follows:
I = 1.5x² + xy, from x = -4 to x = 2.
Then, applying the Fundamental Theorem of Calculus, the result is given as follows:
I = 1.5(2)² + 2y - 1.5(-4)² + 4y = 6y - 18.
Then the outer integral is calculated as follows:
[tex]O = \int_{-4}^{2} 6y - 18[/tex]
Then the result is given as follows:
O = y² - 18y, from y = -4 to y = 2.
