The answer will be 8.39 because the third number (8) is above 5 so you have to round up. Good luck!
The answer is -2. The line is going from left to right which makes it negative. Then if you look at the line and do change in y(rise) over change in x(run).
Sales tax rate for the above sweater is charged at the rate of 8%
Step-by-step explanation:
Sweater’s cost initially- 28$
Cost of Sweater after 30.24$
Sales tax rate deducted?
Analysing the above-provided details we conclude that an increase in the cost was probably due to the addition of sale tax.
Sales tax charged= Cost of the sweater after charging- initial cost
= 30.24$-28$
=2.24$
Percentage of sales tax charged= (sales tax charged/initial cost) *100
Substituting the values of the sales tax and initial cost in the above-provided equation-
= (2.24/28) *100
=8%
Hence the Sales tax charged at the sweater was 8%
Roberto overtakes Juanita at the rate of (7.7 mi)/(11 h) = 0.7 mi/h. This is the difference in their speeds. The sum of their speeds is (7.7 mi)/1 h) = 7.7 mi/h.
Roberto walks at the rate (7.7 + 0.7)/2 = 4.2 mi/h.
Juanita walks at the rate 4.2 - 0.7 = 3.5 mi/h.
_____
In a "sum and diference" problem, one solution is half the total of the sum and difference. If we let R and J be the respective speeds of Roberto and Juanita, we have
R + J = total speed
R - J = difference speed
Adding these two equations, we have
2R = (total speed + difference speed)
R = (total speed + difference speed)2 . . . . . as computed above
