Answer:
Total items = $39.90
Sales tax amount = $3.7905
Total cost = $43.691
The clerk's error is using 9.5 as sales tax amount instead of finding 9.5% of the total items
Step-by-step explanation:
Dress = $24.95
Skirt = $14.95
steps the clerk completed.
Step 1: 24.95 + 14.95 = 39.90
Step 2: 39.90 +9.5 = 49.40
Correct steps:
Total items = dress + skirt
= $24.95 + $14.95
= $39.90
Sales tax = 9.5%
Sales tax amount = 9.5% of total
= 9.5/100 × $39.90
= 0.095 × 39.90
= $3.7905
Total cost = Total + sales tax amount
= $39.90 + $3.7905
= $43.6905
To the nearest hundredth
= $43.691
Sales tax is the amount of money imposed by government on the sales of some items
Total cost is the cost of all items including sales tax
For this case we have that by definition, the circumference of a circle is given by:
![C = \pi * d](https://tex.z-dn.net/?f=C%20%3D%20%5Cpi%20%2A%20d)
Where:
d: It is the diameter of the circle
They tell us that:
![d = \frac {35} {2}\\\pi = \frac {22} {7}](https://tex.z-dn.net/?f=d%20%3D%20%5Cfrac%20%7B35%7D%20%7B2%7D%5C%5C%5Cpi%20%3D%20%5Cfrac%20%7B22%7D%20%7B7%7D)
Substituting:
![C = \frac {22} {7} * \frac {35} {2}\\C = \frac {770} {14}\\C = 55 \ cm](https://tex.z-dn.net/?f=C%20%3D%20%5Cfrac%20%7B22%7D%20%7B7%7D%20%2A%20%5Cfrac%20%7B35%7D%20%7B2%7D%5C%5CC%20%3D%20%5Cfrac%20%7B770%7D%20%7B14%7D%5C%5CC%20%3D%2055%20%5C%20cm)
Thus, the circumference of the circle is 55 centimeters.
Answer:
Option B
This is actually a trick question if you were to take this question head on. Say for instance you are cutting all the pieces from the same sheet of metal, the equation would NOT be 8 times 5 equals 40 minutes, but rather 7 times 5 equals 35 minutes. this is because on the 7th cut, it takes that from 6 sheets of metal to 8 because you get 2 from that cut. Take for instence, a Hersheys candy bar. It is 3 bars thick, but it only takes 2 breaks to sever the 3 strips. So, that being said, sam will make 7 cuts and those 7 cuts will make a times of 35 minutes.
