The result of the expression (x / m^2 - 2x / m)(3x^2y / m) is (3x^3y / m^3) - (6x^3y / m^2)
The given expression is
(x / m^2 - 2x / m)(3x^2y / m)
Here we have to apply distributive property
The distributive property states that multiplying the sum of two or more variable by a number gives the same result as when each variable is multiplied individually by the number and the products are added together.
The distributive property of subtraction is
A(B-C) = AB - AC
Apply the distributive property
(x / m^2 - 2x / m)(3x^2y / m)
= (x / m^2)(3x^2y / m) - (2x / m)(3x^2y / m)
Multiply the terms
= (3x^3y / m^3) - (6x^3y / m^2)
Hence, the result of the expression (x / m^2 - 2x / m)(3x^2y / m) is (3x^3y / m^3) - (6x^3y / m^2)

The ratio of the heights of similar cones is 5:2. If the base area of the small cone is 64pi cm^2, find the base area of the large cone. Thanks!
Answers
Answer: 400π
Explanation:
From the information given, the ratio of the heights is 5:2. This means that the scale factor is 5:2. This means that the ratio of the areas is
(5/2)^2 = 25/4 = 25:4
Thus,
base area of large cone/base area of small cone = 25/4
Given that base area of small cone is 64π, it means that
base area of large cone/64π = 25/4
By cross multiplying,
base area of large cone = 25/4x 64π
base area of large cone = 400π

If f(x) = 2x - 9, which of the following are correct? Select all that apply. f(-1) = -11 f(2) = 5 f(3) = -3 f(0) = -9 f(-3) = 15
Answers
The correct options are f(-1) = -11, f(3) = -3 and f(0) = -9.
Given equation:-
f(x) = 2x - 9
We have to find which of the following are correct:-
f(-1) = -11 ,f(2) = 5 ,f(3) = -3 ,f(0) = -9 and, f(-3) = 15
Putting x = -1 in the given equation, we get:-
f(-1) = 2*(-1) - 9 = -2 - 9 = -11
Hence, this is true.
Putting x = 2 in the given equation, we get:-
f(2) = 2*(2) - 9 = 4 - 9 = -5
Hence, this is false.
Putting x = 3 in the given equation, we get:-
f(3) = 2*(3) - 9 = 6 - 9 = -3
Hence, this is true.
Putting x = 0 in the given equation, we get:-
f(0) = 2*(0) - 9 = 0 - 9 = -9
Hence, this is true.
Putting x = -3 in the given equation, we get:-

What is the ratio of the area of a tile in the model to the area of an actual tile? Use pencil and paper. Describe two ways to find each ratio. The ratio of the length of a tile in the model to the length of an actual tile is?
Answers
Ratio of the length of a tile in model to length of actual tile is 1/9 and Ratio of Area of tile to area of actual tile is 1/ 81
Given,
Length of each tiles = 2/3 in
Width of each tiles = 1/2 in
The actual tiles have length = 1/2 ft = 6 in {1 foot = 12 inch }
Width of actual tiles = 3/8 ft = 4.5 in
Ratio of length of tile in the model to the length of an actual tile =
length of tile / length of an actual tile
= [tex]\frac{2/3}{6} = \frac{1}{9}[/tex]
Area of tiles = area of rectangle = length × width
= 2/3 × 1/2
= 1/3 in²
Area of actual tile = 6 × 4.5 = 27 in²
Ratio of the area of a tile in the model to the area of an actual tile =
Area of tile / area of actual tiles
= [tex]\frac{1/3}{27} = \frac{1}{81}[/tex]
Another way of finding ratio is by Dilation ,
Ratio of lengths = 1 / 9

Ben paid $1200 for a sofa. The price of the sofa Juana purchased was ⅔ the price that Ben paid. How much did Juana pay for her sofa?
Answers
Answer:
800
Step-by-step explanation:
You are at a grocery store and the cost of your groceries is $32.75. You need to add the sales tax, which is 6%. You have one $20 bill, two $10 bills, one $5 bill, five $1 bills, and some pennies.
How much is your total bill including tax?
How much should you give the cashier so you do not get back any pennies?
What denominations will you use for this?
Answers
1. The total bill including sales tax is $34.72.
2. The amount the purchaser should pay the cashier is $34.72.
3. The denominations for the payment should be one $20 bill, one $10 bill, four $1 bills, and 72 cents (pennies).
How is the total cost determined?The total cost payable to the grocery store cashier is the cost of the groceries plus the sales tax.
The cost for groceries = $32.75
Sales tax = 6%
Total cost = cost plus sales tax
= $34.72 ($32.75 x 1.06)
We can check the sum as follows:
Unit Bill Amount
1 $20 $20
1 $10 10
4 $1 4
Cents 0.72
Total $34.72
Thus, the grocery purchaser will be spending $34.72, including the sales tax.

for the lines to be perpendicular the product of slope should be -1,

We have the next information
A submarine Is at a depth of 350 feet below sea level means -350
First, it goes down 150 feet. means -150
Next, it goes up 132 feet. means +132
Then, it goes down 179 feet. means -179
Finally, it goes down 145 feet means -145
then we have the next operations
-350+(-150)+132+(-179)+(-145)=-692
The sing minus means that It is below the sea level
therefore the correct choice is
A It is 692 feet below sea level, because -350 + (-150) + 132 + (-179) + (-145) = -692.
