Karim wants to buy a shirt that normally sells for $46.50. It is on sale for One-third off. How much does Karim need to pay to buy the shirt on sale?
Answers
Answer:
Step-by-step explanation:
First I took the original price of the shirt (46.50) since it is going one third off I divided it by 3 (46.50/3=15.50)
I took away the one third I divided from it (46.50-15.50=31)
I got 31 dollars as my final answer.
Now Karim needs to buy the shirt for $31.
Answer:
$31
Step-by-step explanation:
Price of the shirt normally: $46.50
Deduction in the price when it's 1/3 off: 1/3 * $46.50 = $15.50
amount that Karim needs to pay to buy the shirt:
Price of the shirt normally - Deduction in price when it's 1/3 off =
$46.50 - $15.50 = $31.00

the perimeter of a square can be found using P = n + n + n + n, where n is the length of one side of the square. Which equation could also be used to find the perimeter of a square
Answers
Answer:
P = 4n
Step-by-step explanation:
P = n + n + n + n
If you combine all the like terms you end up with:
P = 4n
The equation to find the perimeter of a square can also be expressed as 4n, where n is the side.
What is Square?A square is a two dimensional figure which has four vertices, four sides and four angles.
Perimeter of a geometrical figure is the sum of the lengths of the boundary of shape.
Given that n is the length of one side of a square.
Perimeter is the sum of the side lengths.
Since a square has four sides,
Perimeter = 4 times the length of side
= 4n
Hence the perimeter of a square can also be expressed as 4n.

1 sack of flour contains 21 cups. It takes 3 cups of flour to make a batch of cookies. How many batches of cookies can you make with TWO sacks of flour?
Answers
1 sack = 21 cups.
so 2 sacks would equal 42 cups because 21x2= 42
and it takes 3 cups of flour to make ONE batch of cookies. So 42 divided by 3 is 14. And that’s how you get your answer.
Answer:
14 batches
Step-by-step explanation:
If 1 sack of flour = 21 cups, and 1 batch of cookies need 3 cups, all you have to do is find out how many batches can be made with 1 sack and double the number:
3 × _ = 21
21 ÷ 3 = 7
7 × 2 = 14
You can make 14 batches of cookies with 2 sacks of flour.

a. The proportion of subjects assigned to take St. John wort is found as follows;
The total number of subjects = 27 + 27 + 37 + 16 + 26 + 13 + 70 + 56 + 66 = 338 subjects
The number of subjects assigned to take St. John wort = 27 + 16 + 70 = 113
The proportion of subjects assigned to take St. John wort = 113/338
b. The distribution of change in depression response using relative frequency is found as follows;
Total full response = 27 + 27 + 37 = 91
Total partial response = 16 + 26 + 13 = 55
No response = 70 + 56 + 66 = 192
