2 answers:
The expression 18 - 0.25(18) can be used to find the new price of pillow.
Step-by-step explanation:
Given,
Cost of pillow = $18
Mark down = 25% =
To find the amount of mark down, we will multiply it with cost of pillow;
Amount of Mark down = 0.25*18
The new price of pillow can be determined by subtracting amount of mark down from the original cost of pillow.
New price = Original Cost of pillow - Amount of mark down
New price = 18 - 0.25(18)
The expression 18 - 0.25(18) can be used to find the new price of pillow.

<em><u>Solution:</u></em>
Given that, Mrs Franklin's speedometer said she was driving at a rate of 48 miles per hour
When checking the accuracy of her speedometer, an Automotive Specialist recorded her speed at 50 miles per hour
<em><u>The percent error is given by formula:</u></em>
Percent error is the difference between a measured and known value, divided by the known value, multiplied by 100%
From given,
Experimental value = 50
Theoretical value = 48
<em><u>Substituting the values in formula, we get,</u></em>
Thus the percent error is 4.167 %
First we need to convert our fractions into decimals, it's just a lot easier to work with.
2 1/2 is equal to 2.5
2 1/4 is equal to 2.25
Then we plug our numbers into the formula used to find the volume of a rectangle:
V=L*W*H
Volume equals Length times Width times Height.
V=2.5*4*2.25
V=22.5
22.5 is already in decimal form, or if you'd rather have a mixed number, your answer is 22
