Jodie bought a refrigerator on sale for 35% off the original price, for $97. What was the price of the refrigerator before the sale?

Answers

$97 = (Original Price) - (35% of Original Price)

$97 = (Original Price) - (0.35 of Original Price)

$97 = (1 - 0.35) of (Original Price)

$97 = (0.65) of (Original Price)

$97 = 0.65 · (Original Price)

Divide each side by 0.65 .

$97/0.65 = Original Price

$149.23 = Original Price

1) Mrs. Clason wants to buy a wireless speaker for her husband. She has narrowed down her choice to two stores:

• Kohls is selling the speaker for $60.00. Mrs. Clason has a Friends and Family discount coupon for 30% off.

• Target purchased the speaker for $38.00 and marked it up by 35% to sell in the store

2) How much would Mrs. Clason be paying for the speaker at Kohl’s? Show your work!

3) Which store would Mrs. Clason get the best deal and by how much is it better? Show

How much would Mrs. Clason pay for this speaker at Target? Show your work

Answers

Answer:

Kohl = $42

Target = $51.30

Best deal is at Kohl's

Step-by-step explanation:

Given ;

At Kohl's:

Selling price = $60

Friend's and family discount = 30% off

(100 - 30)% * $60

0.7 * 60 = $42

At target :

Purchase price = $38

Markup = 35%

Selling price = (100 + 35)% * $38 = 1.35 * 38 = $51.3

Mrs. Clason will get the best deal at Kohl's.

There are 7 red marbles and 9 blue marbles in a bag. What is the ratio of all marbles in the bag to blue marbles? What is the ratio of red marbles to blue marbles?

Answers

Answer:

Answer to the 1st question is: 16/9 or 16:9 (whichever form you use)

Answer to the 2nd question is: 7/9 or 7:9

Step-by-step explanation:

Key skills needed: Number theory, Ratios, and Fractions

1) Let's look at the first question. A ratio is usually a number of something over a number of another thing. One such example is 5 apples : 4 oranges (or 5 apples/ 4 oranges - whichever form you write in).

Based on that let's look at the first problem. We want to find the ratio of all the marbles in the bag to the blue marbles. So it would be --> the total # of marbles over the number of blue marbles. The total number of marbles is 7+9= 16. This would be our first number, or the numerator. The number of blue marbles is 9. This would be our 2nd number, or the denominator of the ratio.With this information --> The ratio would be 16/9 or 16:9                                              

2) Now let's look at the 2nd question. The number of red marbles to the number of blue marbles is the ratio we need to find.  

The number of red marbles is 7. This would be our first number or the numerator. The number of blue marbles is 9. This would be our second number or the denominator. Therefore, the ratio would be --> 7/9 or 7:9

Answer:

f(15,055) is the number of pages in a book with 15,055 words.

Step-by-step explanation:

f(w) = length of book (in pages).

w = number of words

Thus, from the options given, the only true statement about the function is that:

f(15,055) = number of pages of a book that has 15,055 words.

"f(15,055)" is the length of a book consisting of 15,055 words. It does not imply that there are 15,055 pages.

Which expression is equivalent to 5st + 40t

Answers

Answer: 5(1st+8t)

Step-by-step explanation:You factor 5st + 40t  using GCF .And the GCF of 5 and 40 is 5 .So you take 5st and you divide it by 5 and also you take 40 t and divide it by 5 too.And after you take 5st and you divide it by 5 ,you get 1 st .To add on,after you take 40 t and divide it by 5 you get 8t .Finally ,you take the GCF which is 5 and place  Parentheses next to it and you take 1st and 8t and you add them together .

So your expression that is equivalent to 5st + 40t ,is 5(1st+8t) .

What is Equation?

Two expressions with equal sign is called as equation.

We need to change the sentence "The sum of five times a number and seven is equal to twelve" to equation.

In the equation, times represent multiplication and sum represents addition.

five times a number=5n

The sum of five times a number and seven= 5n+7

The sum of five times a number and seven is equal to twelve=5n+7=12.

Therefore option A is correct. The sum of five times a number and seven is equal to twelve is 5n + 7 = 12

The average of the first five multiple of 7 is
a. 7
b. 14
c. 21
d. 28
n innings In the tenth innings he sco​

Answers

Answer:

b. 21

Step-by-step explanation:

The first five mutiples of 7 are: 7, 14, 21, 28, 35. You can get these by multiplying 7 to any integer.

7x1 = 77x2 = 147x3 = 217x4 = 287x5 = 35

In order to get the average of these numbers, you have to add them and divide the sum to the total number of multiples.

Let's add first.

7+14+21+28+35 = 105

Let's divided 105 by 5, which is the number of the multiples of 7.

105÷5 = 21

The answer is 21.

Who walked at a faster rate?

Answers

Well, both Alden and Kira walked at the same rate.
The reason for that is because 2 miles : an hour is the same thing as 1 mile : half an hour.
For example, when you take 2 miles : an hour and you divide them by half or two, you get the answer of 1 mile : half an hour or 30 minutes.
So, in conclusion, both Alden and Kira walked at the same rate.
