Answer:
Joey has 18 nickles and 27 dimes in his piggy bank.
Step-by-step explanation:
1 nickle = 5 cents
1 dime = 10 cents
$1 = 100 cents
$3.15 = 135 cents
Let
n represent the number of nickles, n>=0
d represent the number of dimes, d>=0
Joey counted a total of 45 coins that added up to $3.15:
n + d = 45
5n + 10d = 315
n = 18 nickles
d = 27 dimes
To solve this problem you you would use 3.14 and multiply it by your radius squared, then multiplied by 4. You would end up getting 452ft cubed.

Step-by-step explanation:
By applying section formula we got that y-coordinate of the point that divides the directed line segment from J to K into a ratio of 5:1 is 
<h3>What is section formula ?</h3>
Let point P(x,y) cuts line joining point
and
in
then coordinate of point P is equal to 
Here given that point divides line segment from J to K into a ratio 5:1
So

Now we have to fin y coordinate of point that divides the directed line segment from J to K into a ratio of 5:1
We can calculated y coordinate by applying section formula as :
