Joey is buying a new flat-screen TV for $359.99. Sales tax in Joey's state is 8.25%. Calculate the amount of sales tax that Joey will pay for the purchase
A. $2.97
B. $389.69
C. $29.70
D. $43.64
The amount of sales tax that Joey will pay for the purchase is $29.70.
This can be calculated by multiplying the price of the TV by the sales tax rate:
$359.99 * 0.0825 = $29.70
So the correct answer is C. $29.70.
A package of 6 pairs of sock costs $5.16. How will the rate per pair change if the price for the package decreases to $4.50
A.The price decreases by $0.66 per pair.
B.The price decreases by $0.11 per pair.
C.The price decreases by $0.75 per pair.
D. The price decreases by $0.09 per pair.
To find the rate per pair, we need to divide the total price of the package by the number of pairs in the package.
The initial price for the package is $5.16 for 6 pairs.
Rate per pair = $5.16 / 6 = $0.86 per pair.
If the price decreases to $4.50 for the package, then the new rate per pair would be:
$4.50 / 6 = $0.75 per pair.
Therefore, the rate per pair would decrease by $0.11.
The correct answer is B. The price decreases by $0.11 per pair.
If the measure of one angle is x degrees, which equation represents the relationship between x and its supplementary angle, y, in degrees
A. x = 180 + y
B. x + y = 180
C. x = 360- y
D. x - y =180
The relationship between an angle and its supplementary angle is that the sum of their measures is 180 degrees.
Therefore, the equation representing the relationship between x and its supplementary angle y would be:
B. x + y = 180.
The table below shows the relationship between x, the number ofminutes Jackson has been reading, and y, the total number of pages he has read
minutes(x) total pages ( y)
10 5
15 7.5
20 10
25 12.5
Which equation represents the realationship in the table?
A. y=2x-15
B. y= x-5
C. y= 2x
D. y= 0.5x
The relationship between x (minutes) and y (total pages) in the table is that the number of pages read is equal to half of the number of minutes.
Therefore, the equation representing the relationship is:
D. y = 0.5x.
