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

The answer is 70 maybe?

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.

Step-by-step explanation:

Write the number 4 2/3 as an improper fraction.

Answers

14/3! First you start with multiplication from the denominator to the whole number. 3x4 is 12. Now, you add the numerator. In this case that is 2, so 12+2=14. Now it has to be a fraction, so you take the denominator, in this case 3. So, your answer should be 14/3.

The improper fraction 14/3.

To convert the mixed number 4 2/3 to an improper fraction, we need to find the equivalent fraction where the whole number and fraction parts are combined.

Step 1: Multiply the whole number (4) by the denominator of the fraction (3):

4 * 3 = 12

Step 2: Add the product from Step 1 to the numerator of the fraction (2):

12 + 2 = 14

Step 3: Write the result from Step 2 as the numerator, keeping the same denominator (3):

The improper fraction is 14/3.

Therefore, the mixed number 4 2/3 can be expressed as the improper fraction 14/3.

To understand the result, imagine dividing a whole into 3 equal parts. With 4 wholes, you have 12 parts (4 * 3 = 12). Adding the 2 extra parts (2/3) gives a total of 14 parts out of 3 wholes, which is represented by the improper fraction 14/3.
