Percent Error =
|Experimental Value − Actual Value|
Actual Value × 100
Answer:
The Percent Error is 6%
Experimental Value 17.8mL Actual Value 17.2mL
17.2x100=1720mL

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
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
