Answer:
Step-by-step explanation:
What are we calculating ??? If it is volume of a cone=1/3πr^2h
1/3×3.142×4×4×6
=100.54units cube
To calculate volume of cylinder=πr^2h
V=3.142×4×4×6
V=301.63 units cube
Answer:
.2 <em>or </em>1/5
Step-by-step explanation:
First, calculate the total points by adding the two half's totals together.
7 + 18 = 25
Now, divide the number of points Mary scored by the total.
5 / 25 = 1/5

Answer: The book costs $10 and the pen costs $4✔️
Step-by-step explanation:
Let B the cost of the book and let P the cost of the pen.
Then we know:
The book and the pen cost $14:
B + P = $14 } Equation 1
We also know:
The cost of the book is two dollars more than twice the cost of the pen.
B = 2P + $2 } Equation 2
Now we can substitute the value of B from the equation 2 in the equation 1:
2P + $2 + P = $14
3P = $14 - $2 = $12
P = $12/3 = $4 , cost of the pen
Since we know the value of B from the equation 2, we can calculate B:
B = 2P + $2 = 2x$4 + $2 = $8 + $2 = $10 , cost of the book
Answer: The book costs $10 and the pen costs $4✔️
<h3>Verify </h3>
We can substitute these values in equations 1 and 2 and check the results:
B + P = $14 } Equation 1
$10 + $4 = $14 ✔️check!
B = 2P + $2 } Equation 2
$10 = 2x$4 + $2 = $8 + $2 = $10 ✔️check!
