Find the volume between the cone
X= sqrt(y^2 + z^2) and the sphere
x^2 + y^2 + z^2 = 16.
The volume between the cone and the sphere is approximately 23.55 cubic units.
We are given that;
[tex]X= sqrt(y^2 + z^2)[/tex]
[tex]x^2 + y^2 + z^2 = 16.[/tex]
Now,
To find the volume between the cone and the sphere, we can use a triple integral in spherical coordinates.
The cone corresponds to the equation [tex]$\rho = 2\cos(\phi)$[/tex], where [tex]$\rho$[/tex] is the radial distance, [tex]$\phi$[/tex]is the polar angle, and [tex]$\theta$[/tex] is the azimuthal angle. The sphere corresponds to the equation [tex]$\rho = 4$[/tex]. The limits of integration are:
[tex]$0 \leq \theta \leq 2\pi$$0 \leq \phi \leq \frac{\pi}{4}$$2\cos(\phi) \leq \rho \leq 4$[/tex]
The volume element in spherical coordinates is [tex]$\rho^2\sin(\phi)d\rho d\phi d\theta$[/tex]
Therefore, the volume is:
[tex]$V = \int_{0}^{2\pi}\int_{0}^{\frac{\pi}{4}}\int_{2\cos(\phi)}^{4}\rho^2\sin(\phi)d\rho d\phi d\theta$[/tex]
Evaluating this integral, we get:
[tex]$V = \frac{32}{3}\pi - 8\sqrt{2}\pi + 16\pi$[/tex]
Therefore, by volume of cone the answer will be 23.55 cubic units.

2c +10 = 30
How can I solve this?
Step-by-step explanation:
2c+10=30
2c+10−10=30−10
2c=20
2c÷2=20÷2
Answer: c=10
Answer:
10
Step-by-step explanation:
2c + 10 = 30
so we take 10 to the other side to become - 10.
Therefore 2c = 30 - 10
= 20
Divide both sides by the coefficient of c that's 2
2c = 20
c = 10
HELP PLEASE! IS THIS PROPORTIONAL??
Answer:
Porportional
Step-by-step explanation:
-1 x = -15 y
-7 x -15 = -105, correct
-9 x -15 = -135, correct
Because all are correct, this is porportional. This means that there is a unit rate and if this were graphed, the line would be straight.

Exercise 12-4 Pooling overhead cost LO 12-2 Stuart Manufacturing Company produced 2,600 units of inventory in January 2018. It expects to produce an additional 8,700 units during the remaining 11 months of the year. In other words, total production for 2018 is estimated to be 11,300 units. Direct materials and direct labor costs are $82 and $66 per unit, respectively. Stuart expects to incur the following manufacturing overhead costs during the 2018 accounting period:
Production supplies $ 6,200
Supervisor salary 188,000
Depreciation on equipment 134,000
Utilities 29,000
Rental fee on manufacturing facilities 224,750 Required
1. Combine the individual overhead costs into a cost pool and calculate a predetermined overhead rate assuming the cost driver is number of units. 2. Determine the cost of the 2,600 units of product made in January.
Answer:
Results are below.
Step-by-step explanation:
Giving the following information:
Total number of units= 11,300
Total overhead= 6,200 + 188,000 + 134,000 + 29,000 + 224,750= $581,950
To calculate the predetermined manufacturing overhead rate we need to use the following formula:
Predetermined manufacturing overhead rate= total estimated overhead costs for the period/ total amount of allocation base
Predetermined manufacturing overhead rate= 581,950 / 11,300
Predetermined manufacturing overhead rate= $51.5 per unit
Now, we can calculate the total cost of making 2,600 units:
Total cost= (82 + 66 + 51.5)*2,600
Total cost= $518,700

Find the area of a square with side length x when x is equal to the given value. Is the area of a square and the length of its side directly proportional? Justify your answer.
1. x=15 ft.
2. x=10 in.
3. x=3 in
Answer:
x = 3 in
Step-by-step explanation:
Since it's a square, to find the area, all you have to do is multiply one side of the square by another. Since this is a square, all the sides are equal. so 3x3 = 9. 9 sq. in.
Erin has quarters and nickels for a total of 16 coins. The value of his coins is $2.60. Let represent the number of quarters and y represent the number of nickels
Note: Consider we need to find each type of coins he has.
Given:
Erin has quarters and nickels for a total of 16 coins.
The value of his coins is $2.60.
To find:
The number of each type of coins.
Solution:
Let x represent the number of quarters and y represent the number of nickels.
According to the question,
Total coins : [tex]x+y=16[/tex] ...(i)
Total value : [tex]0.25x+0.05y=2.60[/tex] ...(ii)
Multiply equation (i) by 0.25 and subtract the result from (ii).
[tex]0.25x+0.05y-0.25(x+y)=2.60-0.25(16)[/tex]
[tex]0.25x+0.05y-0.25x-0.25y=2.60-4[/tex]
[tex]-0.20y=-1.40[/tex]
Divide both sides by -0.20.
[tex]y=7[/tex]
Put y=7 in (i).
[tex]x+7=16[/tex]
[tex]x=16-7[/tex]
[tex]x=9[/tex]
Therefore, the number of quarters is 9 and number of nickels is 7.

Step-by-step explanation:
a gold mine extracted 500,000 ounces. gold is priced at present time at $460 per ounce. the mine holds gold for 3 years. if inflation (for gold) is 5.17% per year, how much money will they receive for selling in 3 years all 500,000 ounces in actual dollars
Answer:
$267,536,000Step-by-step explanation:
Step one:
given data
total ounces=500,000
cost per ounce= $460
total amount of the ounce= 500,000*460= $230000000
Time t=3years
rate= 5.17%= 0.0517
Step two:
The inflation we have a compounding effect on the amount
$230000000
A=P(1+r)^t
A=230000000(1+0.0517)^3
A=230000000(1.0517)^3
A=230000000*1.1632
A=$267,536,000
They will receive a total of $267,536,000
It cost $3.45 to buy 3/4 lb of chopped walnuts. How much will it cost to buy 7.5 lbs of walnuts?
Answer:
$34.5
Step-by-step explanation:
Turning the 3/4 into a decimal would be .75, .75 can go into 7.5 10 times. You would multiply 10 by the cost $3.45 and you would get $34.5 for 7.5 lbs of walnuts.

Answer:
106.33
Step-by-step explanation:
after decimal you have .3 tenths 2 hundredths 7 thousandths
to round to the nearest hundredths look at thousandths 7 becasuse is greater then 5 then you round up
106.327 is rounded to 106.33
Answer:
your answer is 106.3
Step-by-step explanation: so first you do this
[tex]106.327\\3 =tenths\\2= hundredths[/tex]
so when you round if it is 5 or above you round up if it is 4 or below leave it alone
so the final answer is 106.3
when you round the 27 is removed and this is what you have left.

Answer:
2
Step-by-step explanation:
given f(x) = 4x-10
to find f(3), we simply substitute x = 3 into the function:
f(x) = 4x-10
f(3) = 4(3)-10
= 12-10
= 2
Answer:
2
Step-by-step explanation:
Since f(3), replace all the x's with 3s
f(3) = 4(3) - 10
