Principal Amount = P = $250
Interest Rate = r = 9% = 0.09
Time in years = t = 15 years
Value of investment = A = ?
The formula to calculate the value on investment as a result of annual interest is:
Using the values in the above formula, we get:
Thus, at the end of 15 years the value of the investment will be $ 910.62.
Answer:
(a) The minimum Edward would have to spend is $31.24
(b) The maximum Edward could spend is $33.34
Step-by-step explanation:
(a) Edward would spend a minimum of $31.24 if he gets either 10 zinnias, 8 pansies and 8 marigolds or 10 marigolds, 8 pansies and 8 zinnias.
(b) Edward could spend a maximum of $33.34 if he gets 10 pansies, 8 zinnias and 8 marigolds.
Answer:
It would take 4 weeks
Step-by-step explanation:
We can solve this problem most easily by forming it into an equation. We could represent weeks as <em>w.</em>
Since you train 5 more minutes every week, we could represent that as 5<em>w</em>, showing that you work 5 minutes times the number of weeks you worked out.
The constant would be adding 10, since you started out working 10 minutes a day. Now lets just write the equation!
10+5<em>w</em>=30
All we have to do is solve.
Subtract 10 on both sides to cancel out the positive 10.
5<em>w</em>=20
Now just divide both sides by 5 to isolate the <em>w</em>.
w=4
It would take him 4 weeks
Hope this helps!
Volume of a cylinder= (height) x area of the base (circle)
We know the height = 160 cm (given), let's find the radius of the base.
The circumference of the base = 87.92 = 2πR==> R=87.92/(2π) =13.993 cm
Area of circle = πR²=π(13.993)² = 615.128 cm²
Hence the volume of the cylinder = 615.128 x 160 = 92,420.48 cm³
