Answer:
here you go
Step-by-step explanation:
First: work out the difference (increase) between the two numbers you are comparing.
Increase = New Number - Original Number.
Then: divide the increase by the original number and multiply the answer by 100.
% increase = Increase ÷ Original Number × 100.

Which of the following is a step in multiplying 3/4 by 3/5? 2 А Adding 3 and 3 B. Finding the lowest common denominator of 4 and 5 C Multiplying 3 and 3 D Multiplying 3 and 5
=================================================
Explanation:
When you multiply fractions, you multiply the numerators together. So in this case we multiply 3 and 3 getting 9 as the updated numerator.
We also multiply the denominators together. The updated denominator is 4*5 = 20.
Overall, (3/4)*(3/5) = (3*3)/(4*5) = 9/20
The fraction 9/20 cannot be reduced because 9 and 20 do not have any common factors other than 1.
We don't have to worry about getting the LCD (lowest common denominator) since that is only applicable for adding and subtracting fractions.

A rectangular prism is 15 inches long, 8 inches wide, and 6 inches high. What is the volume of a pyramid that has the same height as the prism.
Answer:
[tex]240 in^3[/tex]
Step-by-step explanation:
I'm assuming the pyramid base has to fit the prism, else the answer would be "as big as you want.
Now if you compare the formulas for the volume of a pyramid and a prism, you notice that the only difference is a factor of 1/3 (it will take 3 pyramids to fill a prism).
Volume of the prism is the product of the sides, ie [tex]15\cdot8\cdot6 = 720 in^3[/tex]. Volume of the pyramid will be 1/3rd of that, or [tex]240 in^3[/tex]

A container of rain water is evaporating 1.2 centimeters a week. After 8 weeks what will be the change in rain water levels
Answer:
8.667
Step-by-step explanation:
After 8 weeks, the change in rainwater levels will be 9.6 centimeters.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
PEMDAS rule means the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.
A container of rainwater is evaporating 1.2 centimeters a week.
After 8 weeks, the change in rainwater levels will be given as,
⇒ 1.2 x 8
⇒ 9.6 centimeters
After 8 weeks, the change in rainwater levels will be 9.6 centimeters.

A tourism agency can sell up to 1500 travel packages for the Sugar Bowl college football postseason game in New Orleans. The package includes airfare, weekend accommodations, and the choice of two types of flights: a nonstop flight or a two-stop flight. The nonstop flight airplane can carry up to 150 passengers, and the two-stop flight airplane can carry up to 100 passengers. The agency can locate no more than 12 planes for the travel packages. The tourism company makes a profit of $1100 for each non-stop flight airplane sold and $800 for each two-stop flight airplane sold. Assume that each plane will carry the maximum number of passengers.
Define the variables for this situation.
Write a system of linear inequalities to represent the constraints.
Graph the system of linear inequalities and shade the feasible region that shows the area of the graph representing valid combinations of nonstop and two-stop flight packages. Be sure to label your axes with correct increments.
Write an objective function that maximizes the revenue for the tourism agency.
Find the maximum revenue for the given constraints and give the combination of flights that achieves this maximum.
The maximum revenue would be _______________ and would be achieved using _____ nonstop flights and _____ two-stop flights.
The maximum revenue would be $9600 and would be achieved using 0 nonstop flights and 12 two-stop flights.
How to define the variablesLet x = number of non-stop airplanes
Let y = number of two-stop airplanes
The system of linear inequalitiesUsing the variables in (a), we have the following constraints
Total passenger constraint: 150x + 100y <= 1500
Total Airplanes constraint: x + y <= 12
Graph the feasible region.In (b), we have the following system of linear inequalities
150x + 100y <= 1200
x + y <= 12
See attachment for the graph
The objective functionThe objective function of the constraints is:
Max z = 1100x + 800y
The maximum revenueFrom the graph of the function, the optimal solution is:
(x,y) = (0,12)
So, the maximum revenue is:
z = 1100x + 800y
z = 1100*0 + 800*12
z = 9600
Hence, the maximum revenue is $9600

Eddie and Janice are buying school supplies. Eddie buys 5 notebooks and 6 binders for a total of $25.45. Janice buys 4 notebooks and 8 binders for $30.60. What is the cost of each item?
Answer:
Notebook $1.25
Binder $3.20
Step-by-step explanation:
5n + 6b = 25.45
4n + 8b = 30.6
Multiply the first equation by -4.
Multiply the second equation by 5.
Add the equations.
-20n - 24b = -101.8
20n + 40b = 153
16b = 51.2
b = 3.2
5n + 6(3.2) = 25.45
5n + 19.2 = 25.45
5n = 6.25
n = 1.25
Answer:
Notebook $1.25
Binder $3.20
