Answer:
Should be Product of two expression is (6x-y)(2x-y)=12x^2-8xy+y^2
Actual cost of the TV = $175.95
Percentage of discount given on the TV = 20%
Then
Amount of discount on the TV = (20/100) * 175.95 dollars
= 175.95/5 dollars
= 35.19 dollars
So cost of the TV after discount = (175.95 - 35.19) dollars
= 140.76 dollars
Now
Percentage of sales tax that needs to be added = 6%
Then
Amount of sales tax that needs to be added = (6/100) * 140.76 dollars
= 844.56/100 dollars
= 8.45 dollars
Then
Price of TV after adding sales tax = (140.76 + 8.45) dollars
= 149.21 dollars
So the cost of the TV after deducting the discount and adding the sales tax is $149.21
Answer:
Mean-17
Median-3
Mode-3
Range-47
Greatest Value-47
Least Value-0
Step-by-step explanation:
Mean= Add every number up then divide by how many numbers there are
Median= It has an even number in total when ordered from least to greatest. So take the two middle numbers together and divide them by 2.
Mode= The number that occurs more often
Range= The difference between the highest and the lowest number.
47-0=47
Greatest and lowest value= the highest and lowest number in a data set.
Answer: He will pay $630 over the course of the loan.
Step-by-step explanation:
Formula for simple interest :
S.I. = PRT, where P=principal amount , R =rate of interest ( in decimal), T=time (in years)
As per given ,
P = $1,400 , t = 5 years , r = 9% = 0.09
Simple interest = (1400) x (0.09) x (5)
⇒ Simple interest = $ 630
Hence, he will pay $630 over the course of the loan.
Answer:
w = 
Step-by-step explanation:
We can find the formula for the width by isolating w:
V = lwh
Divide each side by lh to isolate w:
= w
