here is the question:

Answer: the rate of the water level in the cone falling when it is 5cm from the bottom of the cone is -0.1768 cm/sec

Step-by-step explanation:

Given the data in the question;

H/h = R/r

10/5 = 6/r

r 1 = 30/10 = 3

Also

10/h = 6/r

r2 = 6h/10 = 3/5 × h

Volume = 1/3πr²h

V = 1/3 × π × (3/5 × h)² × h

V =  1/3 × π × 9/25 × h³

V = 3π/25 × h³

Now

dv/dt = 3π/25 × 3 × h² × dh/dt

-5 = 3π/25 × 3 × 25 × dh/dt

-5 = 3π × 3 × dh/dt

-5 = 9π × dh/dt

dh/dt = -5/9π

dh/dt = -0.1768 cm/sec

therefore, the rate of the water level in the cone falling when it is 5cm from the bottom of the cone is -0.1768 cm/sec

Answer:

Step-by-step explanation:

(5.9k+9.3m) + (3.6k−3.9n) + (3.5n+3.4m) = 9.5k + 12.7m -0.4n

Hi there!

[tex]\large\boxed{5n(n + 2)}[/tex]

Factor the polynomial by finding the GCF from each term:

5n² + 10n

Both terms share "5n", so we can factor this out of the expression:

5n(n) + 5n(2)

5n(n + 2)

Answer:

C, 60 degrees

Step-by-step explanation:

Since "8" is the largest length on the triangle, that must mean that 90 degrees is the largest angle of the triangle. Plus, we know that whenever an angle is 90 degrees, no other measure of the triangle can be < 90 degrees. Therefore the answer cannot be B. Since "8" and "7" are very close (7 and x are a "pair" just like 8 and 90 degrees were), we can guess that x must be relatively close to 90 degrees. Therefore the closest answer to 90 degrees without being greater than 90 is C, 60 degrees.

Step-by-step explanation:

-6x +18 < 30

-6x < 12

x> -2

Answer:

its c

Step-by-step explanation: you subtract 18 from the left and add it to the right so you add 18 to 30 which gets you 48 then you divide 48 by -6 and reverse < to > since your dividing this by a negative

hopefully you understand give me a rate please!

Step-by-step explanation:

[tex] = 12 + {4y}^{2} - 7[/tex]

[tex] = 12 + {4(3)}^{2} - 7[/tex]

[tex] = 12 + 4(9) - 7[/tex]

[tex] = 12 + 36 - 7[/tex]

[tex] = 48 - 7[/tex]

[tex] = 41[/tex]

Answer:

x=4 and y=2

Step-by-step explanation:

I'm not 100% sure but I substituted different numbers into the equation:

If x=4 and y=2 then 4+2=6 and 3x2=6 so it would be 6=6

Another option is x=7 and y=3 then 7+2=9 and 3x3=9 so it would be 9=9

I'm more confident with x=4 and y=2 because of the small size of the triangle.

I hope this helps! Good luck! :)

Sheldon makes a profit of $8.

The ratio of profit share in a partnership is always constant irrespective of the amount of profit.

Given,

Sheldon makes $2 in profits for every $5 that Leonard makes.

Therefore, ratio of profits of Sheldon and Leonard is 2/5.

If Leonard makes profit of $20

Then,  Sheldon's profit / Leonard's profit = 2/5

           Sheldon's profit / 20 = 2/5

           Sheldon's profit  = $8

Hence, Sheldon makes a profit of $8 If Leonard makes $20 profit.

Answer:

223.34 m/s

Step-by-step explanation:

Given :

Travel time = 11 :23 pm to 1:00 a. M = 1 hour 37 minutes = (60 + 37) = 97 minutes = (97 * 60) = 5820 seconds

Distance between Seattle and San Francisco is

807.7 miles (culled from the internet)

807.7 miles = 1299867.1 meters

Average speed = Distance covered / Time taken

Average speed = 1299867.1 m / 5820 s

Average speed = 223.34486

Average speed = 223.34 m/s

Step-by-step explanation:

The equivalent value of {x} is equivalent to 2.046.

The cosine function (or cos function) in a triangle is the ratio of the adjacent side to that of the hypotenuse.

Given is the expression as -

cos(47) = x/3

We have the expression as -

cos(47) = x/3

{x} = 3 cos(47)

{x} = 3 x 0.682

{x} = 2.046

Therefore, the equivalent value of {x} is equivalent to 2.046.

Answer:

56°

Step-by-step explanation:

Given that:

Height of flagpole = 18

Length of shadow = 12

The angle of elevation of tbe sun at the time of the day = θ

Uding trigonometry :

Tanθ = opposite / Adjacent

Tan θ = height of flagpole / length of shadow

Tan θ = 18 / 12

Tan θ = 1.5

θ = tan^-1 (1.5)

θ = 56.309

θ = 56° (nearest degree)

Answer:

Step-by-step explanation:

2) x - y = 2/3

         [tex]x = \frac{2}{3} + y[/tex]

3) 3x +2y = 6

          3x = 6 - 2y

Divide the equation by 3

[tex]\frac{3x}{3}=\frac{6}{3}-\frac{2y}{3}\\\\x = 2 - \frac{2}{3}y[/tex]

4)

[tex]\frac{1}{4}x + y = 2\\\\ y = 2 - \frac{1}{4}x[/tex]

5) 4x - 3y = -33

         -3y = -33 - 4x

Divide the equation by (-3)

[tex]\frac{-3}{-3}y=\frac{-33}{-3} - \frac{4}{-3}x\\\\ y = 11 + \frac{4}{3}x[/tex]

1) Yes, it was easy to solve one variable in terms of the other.

2) Yes, it was easy to solve for y in terms of x. Coefficient of x was a fraction.

3) It will be easy if we take the value of x as multiples of 3

Example: if x = 3,

[tex]y = 11 + \frac{4}{3}*3 \\\\y = 11 + 4\\\\y = 15[/tex]
