At the beginning of the school year, Jayden's mother put $80 in his cafeteria account. Each time Jayden orders lunch, it deducts $2.75 from his account balance.

Answers

Answer 1

Answer:

[tex]y = 80 - 2.75n[/tex]

Step-by-step explanation:

Given

[tex]Beginning = 80[/tex]

[tex]Rate = 2.75[/tex]

Required

Model the situation using an equation

Represent the number of orders with n

Represent the balance with y

y is calculated as:

[tex]y = Beginning - Rate * n[/tex]

We used minus because the amount is being deducted

[tex]y = 80 - 2.75* n[/tex]

[tex]y = 80 - 2.75n[/tex]

Write an
algebraic expression to represent the area of the shaded region:
2y
4y + 3

Answers

Answer:

4y^{2}+3y  

Step-by-step explanation:

First you need to distribute the values.  

(4y+3)(2y) Using the "Rainbow Method" to multiply the polynomials  

You Should get  

8y^{2}+6y  

Since this is the area of the rectangle and we need to find the area of the shaded region you need to dived 8y^{2}+6y in half because the shaded region is half of the rectangle.  

8y^{2}+6y/2  

Doing this you will get  

4y^{2}+3y

3. Ana's bedroom measures 8-feet by 12-feet. She
wants to set up a corner of her room for arts and
crafts and wants to use one fourth of the dimensions
of her room for it. What will be the area of her arts
and crafts corner?

Please help me! Show work please. Sorry:(

Answers

If she wants one fourth of the dimensions of the room for the corner, that means the area will be 1/16 (one fourth squared) of the whole bedroom. The area of the whole bedroom is 8 x 12 = 96. The area of the corner would be 96 / 16 = 6 sq ft.

Or you can do (one fourth of 8) x (one fourth of 12) = 2 x 3 = 6 sq ft.

I think a fair argument for the green marbles is that it will be chosen 15/100 times, because if you add all marbles up you get 20 marbles in total, with 3 being green. If you multiply this by five you will get 15/100, therefore this is a reasonable prediction.

If my function rule is 4x, what is the OUTPUT if the input is 5?

So ,

⠀⠀⠀⠀⠀‎─━━━━━━━━━━━━─

Hαppч Sσlvíng !¡ :)

The output of the function rule is 20 for the input is 5.

What is a function?

The function is defined as a mathematical expression that defines a relationship between one variable and another variable.

What are Arithmetic operations?

Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.

The operator that performs the arithmetic operations is called the arithmetic operator.

* Multiplication operation: Multiplies values on either side of the operator

For example 4*2 = 8

We have been given that function rule = 4x.

To determine the output for the input is 5

The input given is 5, hence we must substitute x with 5.

So, the output of the function rule = 4(5) = 20.

Therefore, the output of the function rule is 20 for the input is 5.

Answer:

12 turtles

Step-by-step explanation:

First, if the ratio of fish to turtles is 20:3 and there are 80 fish, then we know that you have to divide 80 by 4 to get the answer 20. However, to find out how many turtles there are you need to do the opposite and multiply instead of dividing. So you do 3 x 4, which get you your answer.
