Answer:
$7803.72
Step-by-step explanation:
We have been given that a silo is in the shape of a cone. The silo is 8 meters tall and it's base has a diameter of 3 meters. Soybeans cost $414 per cubic meter. We are asked to find the total cost to fill the silo with soybeans.
First of all, we will find the volume of silo using volume of cone formula.
, where,
r = radius
h = Height
We know that radius is half the diameter, so radius of silo would be 
.
Now we will multiply total volume by $414 to find total cost.\
Therefore, it will cost $7803.72 to fill the silo with soybeans.
Answer:
Jeremy Will have more than just $200 to spend on Christmas presents.
Explanation :
He has a total of $1200.
He spends a $120 for car insurance. (1)
He needs to spend $25 a week for lunch. He has to do this for 16 weeks so 25*16 = $400. (2)
He needs to spend $20 a week for entertainment. For 16 weeks that'll be 20*16 = $320 (3)
adding (1) (2) and (3)
We get Jeremy's total spending will be $840. Jeremy has $1200.
1200-840 = $360
So Jeremy will have $360 to spend on Christmas present.
Answer:
Step-by-step explanation:
let one diagonal=x
other diagonal=3x
area=1/2 (x±3x)=3/2 x²=54
x²=54×3/2=81
x=9 cm
3x=3×9=27
sum of diagonals=x+3x=4x=4×9=36 cm

Answer:
D = $8637.45
Step-by-step explanation:
Rate = 3.65% = 0.0365
Principal = 5000
Time (t) = 15 years
N = 12 (since its compounded monthly)
Compound interest (A) = P(1 + r/n)^nt
A = 5000(1 + 0.0365 / 12)^15*12
A = 5000(1 + 0.00304)¹⁸⁰
A = 5000(1.00304)¹⁸⁰
A = 5000 * 1.7269
A = 8634.86
The investment would worth $8634.86
Note: the final answer may vary slightly from the answer in the options due to ± from approximation
