You will need to use this formula:
Years = log (total/principal) / n * log (1 + (rate / n))
where "n" is the number of compounding periods per year.
Years = log (9,000/4,790.23) / n * log (1 + (.038 / n))
Years = log (

) / 2 * log (1.019)
Years = 0.27388614314 / 2 * 0.0081741840064
Years = 0.27388614314 /

Answer:
Step-by-step explanation:
EI = IG . . . . . . . . . . . .diagonals of a rectangle bisect each other
2x +7 = 6x -13 . . . . . substitute given expressions
20 = 4x . . . . . . . . . . add 13-2x
5 = x . . . . . . . . . .. . . divide by 4
EI = 2x+7 = 2·5 +7 = 17
FH = 2·EI = 2·17
FH = 34
__
∠IGF = ∠IFG = ∠IEH = ∠IHE = 59° . . . . mirror symmetric angles are congruent
∠EIH = 180° -∠IEH -∠IHE = 180° -2(59°)
∠EIH = 62°
The total to be paid is 909.5.
You must do 7% of 850 which is 59.5 and add it to 850 which is 909.5
Answer:
3 assignments incomplete.
Step-by-step explanation:
context: 75% can be rewritten as 0.75
12 × 0.75 = 9 assignments completed.
The above equation shows the amount of assignments that have been already completed. In order to find out how many assignments she has yet to have completed, we need to subtract these amounts.
12 - 9 = 3 assignments incomplete.
Answer:
12 sales
Step-by-step explanation:
Let x represent the number of sales each man had.
For Salesman A, he earns $65 per sale; this is 65x.
For Salesman B, he earns $40 per sale; this is 40x. We also add to this his weekly salary of $300; this gives us 40x+300.
Since their pay was equal, set the two expressions equal:
65x = 40x+300
Subtract 40x from each side:
65x-40x = 40x+300-40x
25x = 300
Divide both sides by 25:
25x/25 = 300/25
x = 12
