A box of cereal states that there are 87 calories in a 3​-4cup serving. What is the unit rate for calories per​ cup? How many calories are there in2 cups of the​ cereal?

Answers

Answer: for 2 cups, There are 232 Calories.

Step-by-step explanation:

Step 1

Let the calories in one cup be represented as C

 Therefore

3/4 x C = 87 calories

C = 87 X 4 / 3 = 116

unit rate is 116 calories per cup.

Step 2- Solving the number of calories in 2 cups

1 cup serving = 116 calories

2 cups servings = 116 x 2= 232 calories

What is Algebra?

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

Variables are the name given to these symbols because they lack set values.

In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Given:

Ratio of diamonds to emeralds = 1:4.

Total = 16 emeralds

let the common ratio be x.

Emeralds = 4x and Diamonds = x

So, 4x = 16

x= 4

Thus, number of diamonds

= 4

Hence, there are 4 diamonds.

help

Answers

Answer:

The correct option is 72.

Step-by-step explanation:

To calculate this, we first let x represent the number games that must be played to make at least $45.

Based on this, we can have an in equality equation as follows:

2.50x - 135 ≥ 45

We can now solve for x as follows:

2.50x ≥ 135 + 45

2.50x ≥ 180

x ≥ 180 / 2.50

x ≥ 72

This implies that at leats 72 games must be played to make at least $45. Therefore, the correct option is 72.

Step-by-step explanation: reason being is because the figure didnt grow/shrink like it would for a dilation so that gets rid of A. And C. And its not D.

The image A'B'C' is formed by an isometric transformation because all of the vertices moved 2 units right and 2 units down, the correct option is B.

What is Transformation?

Transformation is the process of changing the graph to a new graph by Rotation, Reflection, Translation, and Dilation.

Rotation is a type of transformation of an object on an x-y plane, when an object is turned clockwise or anticlockwise by a certain angle, the object is said to be rotated.

Reflection is creating a mirror image of the object, which is same in shape and size but only the coordinates have been changed.

Translation is moving the object, up, down, left or right on the coordinate axis.

Dilation is changing the size of the object, the original object is either enlarged or compressd by certain scale factor.

The object ABC shown in the image has coordinates A ( -2, 5), B (-5, -3), C(1, -3) and,

The image has the cooridnates A'(0,3), B'(-5,-3) , C'(3, -5).

The coordinates have been transformed by translation.

The transformation is an isometric transformation could have been applied because all of the vertices moved 2 units right and 2 units down.

Sustitute n = 4

= 28 - 12 √(4 ÷ 2)

= 28 - 12√2

= 28 - 12 x 1.414

Evelyn is buying a motorcycle that costs $14,000. The tax rate is 6.75%, and she plans to make a down payment of $1,500. The sales tax is
added before the down payment is applied. She is considering a three-year loan

Answers

Answer:

449.10

Step-by-step explanation:

Her monthly payment, if she is considering a three-year loan is $373.47

Given the cost of the motorcycle to be $14000

If the tax rate is 6.75%, the total cost plus tax is expressed as:

Final cost = 14000+(0.0675 * 14000)

Cost of motorcycle = 14000 + 945

Cost of motorcycle = $14945

If she plans to make a down payment of $1,500 before the sales tax is applied, then;

Balance = 14945 - 1500

Balance = $13,445

If she considers  a three-year loan, her monthly payment will be ;

Monthly payment = 13,445/36

Monthly payment = $373.47

Hence her monthly payment if she is considering a three-year loan is $373.47
