Sand falls onto a conical pile at the rate of 10 cubic feet per minute. The radius of the pile is always equal to one half it altitude. How fast is the altitude of the pile increasing when the pile is 5 feet high?
Answer:
Either one of these.
Step-by-step explanation:
volumepile=1/3 (PI r^2)h
but r=h/2, so
volume=1/12 PI h^3
dv/dt=10 ft^3/min
but dv/dt=1/12 PI 3h^2 dh/dt
solve for dh/dt
This assumes you mean by "altitude" the height. If you mean altitude as slant height, you have to adjust the fromula
_______________________________________________
given: r = h/2
V = (1/3)π r^2 h
= (1/3)π (h/2)^2 (h)
= (1/12) π h^3
dV/dt = (1/4)π h^2 dh/dt
for the given data ...
10 = (1/4)π(25)dh/dt
dh/dt = 10(4)/((25π) = 1.6/π feet/min

7x - y = 3
Group of answer choices
(1 , 4)
(-1 , -4)
(-1 , 4)
(1 , -4)
Answer:
(1, 4)
Step-by-step explanation:
subsitute y=x+3 into the 2nd equation, which you will get 7x-(x+3)=3
get rid of the (), which you will get 7x-x-3=3
combine like terms and get 6x-3=3
move 3 to the other side and divide both sides by 6 and get x=1
use the first equation y=x+3 and subsitude 1 for x and get y=1+3

Answer:
quadrant 3
Step-by-step explanation:
The number of DVDs sold at a store in a month was 925 and the number of DVDs sold decreased by 12 per month. The number of Blu-ray discs sold in the same store in the same month was 507 and the number of Blu-ray discs sold increased by 26 per month. Let d represent the number of discs sold and t represent the time in months.
Write a system of equations by filling in the blanks:
d= _ t+ _
d= _ t+ _
Solve the system of equations using the substitution method. Complete the sentence to describe the solution.
There will be _ DVDs and Blu-Ray discs sold per month in _ months
Answer:
See belowStep-by-step explanation:
DVDs
d = 925 - 12tBlu-rays
d = 507 + 26tSolve the system:
925 - 12t = 507 + 26t26t + 12t = 925 - 50738t = 418t = 418/38t = 11Number of disks sold in 11 months:
925 - 12*38 = 469There will be 469 DVDs and Blu-Ray discs sold per month in 11 months

C. [tex]-2\frac{3}{8}[/tex] < -8/6 < -0.85 < 0.8 < 4/3 < 140% in ascending order.
What is ascending and descending order ?In ascending order we write numbers from smaller to greater and in descending order we write numbers from greater to smaller.
According to the given question we have list of fractions decimals and percentages and we have to write them in ascending order.
given [tex]-2\frac{2}{8}[/tex], - 0.85, 4/3, 140%, -8/6, 0.8.
Now let convert all these into one form we choose to convert them in percentage.
[tex]-2\frac{3}{8}[/tex] is -19/8 = -2.375 = -237.5 %.
-0.85 = - 85%.
4/3 = 133%.
140% = 140%
-8/6 = -133%
0.8 = 80 %.
∴ [tex]-2\frac{3}{8}[/tex] < -8/6 < -0.85 < 0.8 < 4/3 < 140%.

Answer:
20.34 % of annual net income is spend on food.
Step-by-step explanation:
Amount spend on food = $7104
Annual net income = $ 34,910
We need to find what percent of their annual net income is the amount spend on food.
The Formula used will be:
[tex]Percentage=\frac{Amount\:spend\:on\:food}{Annual\:net\:income}\times 100[/tex]
Putting values of amount spend on food and Annual net income and finding percentage
[tex]Percentage=\frac{7104}{34910}\times 100\\Percentage=0.2034 \times 100\\Percentage=20.34\%[/tex]
So, 20.34 % of annual net income is spend on food.

Answer:
The graduate will have $4,084.97 when he cashes in the CD at the end of the 36-months.
Step-by-step explanation:
This can be determined using the formula for calculating the future value (FV) formula as follows:
FV = PV * (1 + r)^n ................................. (1)
Where;
FV = Future value or the amount the graduate will have at end of 36 months = ?
PV = Present value or the total amount invested = Cash gifts from friends and relatives + Amount of 3 scholarships he received = $900 + $250 + $300 + $1,400 = $2,850
r = daily interest rate = 1% / 360 = 0.01 / 360 = 0.0000277777777777778
n = number of days = 36 months * 360 days = 12,960
Substituting the values into equation (1), we have:
FV = $2,850 * (1 + 0.0000277777777777778)^12,960
FV = $2,850 * 1.43332224806396
FV = $4,084.96840698229
Approximating to the nearest cent as required, we have:
FV = $4,084.97
Therefore, the graduate will have $4,084.97 when he cashes in the CD at the end of the 36-months.

4x - 3y = 11
2x - 5y = 25
solve using elimination and substitution method
Answer:
hope it helps forget about my writing
Answer:
(-1.43, -5.57)
Step-by-step explanation:
Elimination:
First we need to line up x or y to be the opposite so they can be eliminated:
4x - 3y = 11
-2( 2x - 5y = 25) which is
-4x + 10y = -50
Next step we cancel out the x but adding both equations which would isolate the y:
7y = -39
y = -5.57
After finding y, plug it back into the equation to find x:
4x - 3(-5.57) = 11
4x + 16.71 = 11
4x = -5.71
x = -1.43
To ensure it is correct, we can plug it back into both equations:
4(-1.43) - 3(-5.57) = 11
2(-1.43) - 5(-5.57) = 25
John is going camping, and he needs to buy a tent. The outdoor store has one that cost $90, but it's on sale for 25% off. What is the sale price?
A.$22.50
B.$65.00
C.$67.50
D.$112.50
Answer:
A
Step-by-step explanation:
Okay so, im not the best at explaining, but so we have a percentage. its 25%. you want to take the 25% and put it over 100 because a percentage is a number or ratio expressed as a fraction of 100. so it will be written as 25%/100
divide 25 by 100 and you get 0.25, correct? so that's one step further towards the answer.
then we write x/90 because we don't know (well we do) what we're gonna put. but, we're gonna multiply 0.25 by 90 and we get 22.5, which is equivalent to 22.50.

B) is the right answer.
Answer:
B
Step-by-step explanation:
We want to solve the inequality:
[tex]\displaystyle \sec\Big(\frac{x}{3}\Big)+4>2-\sec\Big(\frac{x}{3}\Big )[/tex]
First, we can add sec(x/3) to both sides:
[tex]\displaystyle2 \sec\Big(\frac{x}{3}\Big)+4>2[/tex]
Subtracting 4 from both sides yields:
[tex]\displaystyle 2\sec\Big(\frac{x}{3}\Big)>-2[/tex]
And dividing both sides by 2 yields:
[tex]\displaystyle \sec\Big(\frac{x}{3}\Big)>-1[/tex]
Therefore, we can graph the following two functions:
[tex]\displaystyle y=\sec\Big(\frac{x}{3}\Big)\text{ and } y=-1[/tex]
Where our solutions will be all the intervals where y = sec(x/3) is above the line y = -1.
