Julie paid $43 for 8 shirts. At this rate, how much will she pay for 12 shirts?
Answers
Answer:
$64.56
Step-by-step explanation:
If she paid 43 dollars for 8 shirts, then that means she paid about 5.38 dollars each for one shirt. (43/8 = 5.375)
Because we are finding the price for 12 shirts, multiply the price of one shirt ($5.38) by the total number of shirts (12) we are buying so, 5.38*12 = $64.56
Our answer is $64.56. :D
Answer:
$64.50
Step-by-step explanation:
To find the unit rate: 43/8=5.375
To find how much for 12 shirts: 12 x 5.375 = 64.50.

Wendy has 10 ½ pounds of potato salad. She wants to divide the potato salad into containers, each of which holds 1 ¼ pounds. How many containers does she need? Show your work and answer in a complete sentence.
Answers
Answer:
9 containers
Step-by-step explanation:
Since Wendy wants to divide the 10 [tex]\frac{1}{2}[/tex] pounds of the potato salad into 1 [tex]\frac{1}{4}[/tex] pounds for each container, You just divide 10 [tex]\frac{1}{2}[/tex] by 1 [tex]\frac{1}{4}[/tex] using the following method:
Convert 10 [tex]\frac{1}{2}[/tex] into an improper fraction:
[tex]\frac{21}{2}[/tex]
Convert 1 [tex]\frac{1}{4}[/tex] into an improper fraction:
[tex]\frac{5}{4}[/tex]
Then finally divide [tex]\frac{21}{2}[/tex] by [tex]\frac{5}{4}[/tex] :
[tex]\frac{21}{2}[/tex] ÷ [tex]\frac{5}{4}[/tex]
This is the same as [tex]\frac{21}{2}[/tex] times the reciprocal of [tex]\frac{5}{4}[/tex]:
[tex]\frac{21}{2}[/tex] × [tex]\frac{4}{5}[/tex] = [tex]\frac{42}{5}[/tex] = 8.4
Since we cannot have 8.4 containers, we round it up to 9 containers, because for 8 containers, there will still be some pounds of potato salad left.

A rectangle has its diagonal length increased from 5 cm to 25 cm. The new rectangle is similar to the original one. The original perimeter was 14 cm. What is the measure of the new perimeter?
Answers
Answer:
The measure of the new perimeter is 70cm.
Step-by-step explanation:
I thought putting up a picture would be easier than explaining it all. The picture is how you would write out the problem.
The original rectangle's measures were 5cm and 14cm. The new rectangles measures are 25 cm and X (We don't know yet.) So write it out. 5cm is to 14cm as 25cm is to X.
5cm/14cm = 25cm/X
Cross multiply. (The arrows I drew. Multiply diagonally.)
You should get
350 = 5X
We need to get X by itself, so divide both sides by 5.
5X/5 leaves X left
350/5 leaves 70
70 = X
