Answer:
height is 4ft.
Step-by-step explanation:
I used pathagorus theorem .All explaination is in the pic below.
1.) v=(l)(w)(h)
V=(9)(9)(9)
V=(81)(9)
V=729in^3
2.) (I forget if this is the real equation to this but this would give you the same answer)
V=(l)(w)(h)
————
2
V=(8)(6)(12)
————-
2
V=576/2
V=288cm^3
Its not a negative number but a positive number
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%
