X times .3=12 So X equals 12/.3 which is 40. Another way of solving it is dividing 12 by 3 which is 4 then multiply by ten.
Answer:
$81
Step-by-step explanation:
To find this, we have to use various steps.
Each day, she works 4.5 hours and 12 dollars each hour.
So: 4.5x12= 54
She works 5 days a week

She deposits 70 percent So she saves 30%.
So: 270x.3= 81
Answer:
87.5cm²
Step-by-step explanation:
area of trapezium = 1/2 (a+b)h
1/2 × (10 + 15) ×7
1/2 × 25 × 7
1/2 × 175 = 87.5
Answer:
A=$538.82
Step-by-step explanation:
We're going to use the compounded interest formula:
A=P(1+r/n)^n*t
Where,
A = the future value of the investment/loan, including interest
P = the principal investment amount (the initial deposit or loan amount)
r = the annual interest rate (decimal)
n = the number of times that interest is compounded per unit t
t = t is the amount of time at which you're checking how much it's worth (yrs)
Using this information, we can use:
A=500(1+0.025/4)^3*4
A=500(1+0.00625)^12
A=500(1.00625)^12
A=500(1.07763259886)
A=538.82
A=$538.82....
