The volume of a frustum of a cone is given by
.. V = (1/3)*π*h*(R^2 +r^2 +R*r)
We will assume the diameter at the bottom is 1 1/2 inch. Then the slanted part has volume
.. V = (1/3)*π*4*(2.5^2 +.75^2 +2.5*.75) ≈ 36.39 . . . . in^3

The volume of the 1-inch cylinder at the bottom is
.. V = π*(1/2)^2*1 = π/4 ≈ 0.79 . . . . in^3

Then the total volume of the cone is approximately 37.18 in^3.

Ilia_Sergeevich [38]
The correct answer for the question that is being presented above is this one: "<span>The missing digit is 3."</span>

The missing digit is represented by A  ⇒  $1A2, where A represents a whole number from 0 to 9.

Try substituting any number from 0 to 9 for A (the middle digit or tens place) , then divide by 11 members.

<span>Option 2:  A = 3  ⇒  $1 </span><span>3 </span>2
$ 132 ÷ 11 = $12

The only one-digit that gives a whole number quotient when it takes the place of tens digit in $1 __2  is<span> 3.</span><span>   Because $ 132 ÷ 11 = $ 12. (Option 2)</span>

The missing digit is 3.

What is 469.82 plus 8.5 sales tax
alekssr [168]
Hey!


The first step to solving this problem would be to multiply 469.82 by 0.085.

<em>New Equation :</em>
469.82 × 0.085 = ?

<em>Solution {New Equation Solved} :</em>
469.82 × 0.085 = 39.9347

Ignore the forty seven at the end of the solution. You're only going to need 39.93. Now we'll add 469.82 and 39.93. This is the sales tax plus the regular price. Which will then bring us to our total.

<em>New Equation :</em>
469.82 + 39.93 = ?

<em>Solution {New Equation Solved} :</em>
469.82 + 39.93 = 509.75

<em>So, 469.82 plus 8.5 sales tax is</em>  509.75.

Hope this helps!

Emma has 18 yellow flowers and 30 white flowers. She wants to split them into vases in equal groups. What is the largest number
likoan [24]

Answer:

Flowers, yellow flowers, white flowers, group, GCF

For this case we have 18 yellow flowers and 30 white flowers, we must find a number that represents the largest number of groups of flowers that can be formed, bearing in mind that each group must contain the same number of yellow and white flowers. To do this, we must find the GCF (Greatest Common Factor) of yellow flowers and white flowers.

We look for the factors of 18, that is, the numbers for which 18 is divisible, these are:

18, 9, 6, 3, 2 and 1

We look for the factors of 30, that is, the numbers for which 30 is divisible, these are:

30, 15, 10, 6, 5, 3, 2, 1

Thus, we can see that GCF of both numbers is 6.

Then we can form 6 groups of flowers. To know the amount of flowers of each color in each group, we divide:

Thus, 6 groups of flowers can be formed with 3 yellow flowers and 5 white flowers each.

Answer:

The largest number of groups that can be done is 6.

stealth61 [152]

Answer:

Gross profit formula= 3x

x= number of units sold

Step-by-step explanation:

Giving the following information:

Unitary variable cost= $2

Selling price per unit= $5

<u>To calculate the profit earned, we need to use the unitary contribution margin formula</u>. The contribution margin is a product's price minus all associated variable costs (sales- variable costs), resulting in the incremental profit earned for each unit sold.

Unitary contribution margin= 5 - 2 = 3

<u>Now, the profit formula:</u>

Gross profit formula= number of units*unitary contribution margin

Gross profit formula= 3x

x= number of units sold
