Original Price $69.80 Percent of Discount 60% Sale Price = ?

Answers

Answer:

$27.92

Step-by-step explanation:

To find the sale price, multiply the original price by 0.4:

69.8(0.4)

= 27.92

So, the sale price is $27.92

The amount for sale is $27.92.

What is mean by Percentage?

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

Given that;

Original Price = $69.80

And, Percent of Discount = 60%

Hence, Sale price is find as;

Sale price = $69.80 - 60% of 69.80

                = $69.8 - 60/100 × 69.80

                = $69.80 - $41.88

                = $27.92

A restaurant offers three sizes of coffee and four differerſt types of coffee.
Coffee can be ordered with or without cream and with or without sugar.
The restaurant also has six bagel options. A bagel can be ordered plain, with
butter, or with cream cheese. How many different ways can you choose a
coffee and bagel at this restaurant?

Answers

Answer:  864

=======================================================

Work Shown:

There are,

3 sizes of coffee4 types of coffee2 choices for cream (you pick it or you leave it out)2 choices for sugar (same idea as the cream)

This means there are 3*4*2*2 = 12*4 = 48 different coffees. We'll use this value later, so let A = 48.

There are 6 bagel options. Also, there are 3 choices in terms of if you order the bagel plain, with butter, or with cream cheese. This leads to 6*3 = 18 different ways to order a bagel. Let B = 18.

Multiply the values of A and B to get the final answer

A*B = 48*18 = 864

There are 864 ways to order a coffee and bagel at this restaurant.

--------------

If you're curious why you multiply the values out, consider this smaller example.

Let's say you had 3 choices of coffee and 2 choices for a bagel. Form a table with 3 rows and 2 columns. Place the different coffee choices along the left to form each row. Along the top, we'll have the two different bagel choices (one for each column).

This 3 by 2 table leads to 3*2 = 6 individual table cells inside. Each cell in the table represents a coffee+bagel combo. This idea is applied to the section above, but we have a lot more options.

The production cost to make 10 shirts is modeled by the expression 1.By + 5.5, where y represents the number of meters of fabric needed to make the shirts. Which
expression represents the production cost for one shirt?
A.0.18y +0.55
B.0.18y +5.5
C.1.8y +0.55
D.18y +55y

Answers

Answer:

 The answer is 0.18y+5.5

Step-by-step explanation:                

because the only thing you had to do is move the decimal.

The expression which represents the production cost for one shirt is, 0.18y +0.55. So Option A is correct

What are expressions?

An expression is a sentence with at least two numbers or variables having mathematical operation. Math operations can be addition, subtraction, multiplication, division.

For example, 2x+3

Given that,

The production cost to make 10 shirts is modeled by the expression,

Total Cost = 1.8y + 5.5,

where y represents the number of meters of fabric needed to make the shirts

So, for one shirt cost,

Cost of 1 shirt = Total Cost/10

                       = 1.8y + 5.5/10

                       =  0.18y + 0.55

Thus, the expression is  0.18y + 0.55

Answers

Answer:

1/2

Step-by-step explanation:

So we multiply 2 by 6, and get 12.

Then we multiply 1 by 3, and get 3.

Next we give both terms new denominators

So now our fractions look like this:

12/18-3/18

Since our denominators match, we can subtract the numerators.

12 − 3 = 9

So the answer is:

9/18

So we reduce it:

9/18divided by 3=3/6

so since it’s equivalent we reduce it again

3/6divided by 3 which equals 1/2

and that’s our final answer 1/2

2.25(a+1.3)=20.7 What is the value of a?

Answers

Answer:

a=7.9

Step-by-step explanation:

2.25(a+1.3)=20.7 *Distribute (multiply) the 2.25 throughout the parenthesis

2.25a+2.925=20.7 *Subtract 2.925 from both sides

2.25a=17.775 *DIvide by 2.25

a=7.9

The solution of the equation 2.25 (a + 1.3) = 20.7 will be 7.9.

What is the solution to the equation?

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

The equation is given below.

2.25 (a + 1.3) = 20.7

Simplify the equation, then we have

2.25 (a + 1.3) = 20.7

(a + 1.3) = 9.20

a = 9.20 - 1.3

a = 7.9

The solution of equation 2.25 (a + 1.3) = 20.7 will be 7.9.
