You would have to set the equation to the profit Jennifer got, which you know to be 63 dollars:
63=0.5e-5
To begin solving for e, which represents the number of erasers sold, add five to each side to get e alone.
68=0.5e
Multiply each side by two to get a whole x value on the right side
136=e
Jennifer sold 136 erasers
Answer: $6828
Step-by-step explanation:
James annual income = $85350
Income tax = 8%
The amount of income tax in dollars and cents that James has to pay will be calculated by multiplying the income tax by his annual income. This will be:
= 8% × $85350
= 8/100 × $85350
= 0.08 × $85350
= $6828
Answer:
2=p
Step-by-step explanation:
-5p+7=5p-13
+5p +5p
7=10p-13
+13 +13
20=10p
÷10 ÷10
2=p
Answer:
2√3
Step-by-step explanation:
Given the following information,
Long = 3 = Adjacent
Angle of elevation =30 degrees
Required
Hypotenuse
Using SOH CAH TOA identity
Cos theta = adj/hyp
Cos 30 = 3/hyp
hyp = 3/cos30
hyp = 3/√3/2
hyp = 3* 2/√3
hyp = 6/√3
hyp = 6/√3 * √3/√3
hyp = 6√3/3
hyp = 2√3
Hence the hypotenuse is 2√3
