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?
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
What should the following rate be divided by to convert it to a unit rate?
6 inches
________
12 hours
Answer:
Unit rate is a rate that has 1 as denominator.
Given the rate: 6 inches / 12 hours, we have to divide numerator and denominator by 12 to transform the denominator in 1, as follows:
\frac{6}{12} = \frac{6/12}{12/12} =
12
6
=
12/12
6/12
= 0.5 inches/hour

Guys I'm completely lost... Can you please show your work so I know how to get the answer for future problems like this!!
Answer:
0
Step-by-step explanation:
(b+13)/2=5b/1.5
We move all terms to the left:
(b+13)/2-(5b/1.5)=0
We add all the numbers together, and all the variables
(b+13)/2-(+5b/1.5)=0
We get rid of parentheses
(b+13)/2-5b/1.5=0

Put the following fractions in order from least to greatest, 1/8 2/5, 3/5, 1/6 1/4, 2/3, 1/3
Answer:
Order from Least to Greatest
1/8 < 1/6 < 1/4 < 1/3 < 2/5 < 3/5 < 2/3
Step-by-step explanation:
A fraction is a way to describe a part of a whole. The given fractions can be arranged as shown below.
What is a Fraction?A fraction is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25.
In order to put the following fractions in order from least to greatest, we need to take the LCM of the fraction so that all the fractions have the same denominator.
1/8, 2/5, 3/5, 1/6, 1/4, 2/3, 1/3
Since the LCM of 3, 4, 5, 6, and 8 is 120. Therefore, the fractions can be written as,
1/8 = (1/8) × (15/15) = 15/120
2/5 = (2/5) × (24/24) = 48/120
3/5 = (3/5) × (24/24) = 72/120
1/4 = (1/4) × (30/30) = 30/120
2/3 = (2/3) × (40/40) = 80/120
1/3 = (1/3) × (40/40) = 40/120
Now, the fractions can be arranged as,
15/120 < 30/120 < 40/120 < 48/120 < 72/120 < 80/120
Rewriting the fraction in there original form,
1/8 < 1/4 < 1/3 < 2/5 < 3/5 < 2/3

Sammy buys his clothes at SuperDuper Discount Store. On Saturday, he bought shoes regularly priced at $40 for 25% off, and a jacket regularly priced at $100 for 30% off. What is the total amount that he will have to pay? (Omit sales tax.)
Step-by-step explanation:
I know, that's probably a lot to take in! :D
40 × 25% = 10
40 - 10 = 30
The final price of the shoes is $30.
100 × 30% = 30
100 - 30 = 70
The final price of the jacket is $70.
30 + 70 = 100
A N S W E R:
The total price of the items Sammy bought (no including sales tax) is $100.
