24-1 = 23

6-1/4 = 5 3/4

23/5 3/4 = 4

The constant is 4, so Vanessa is correct

The answer is:

D. Vanessa is correct because the quotient when dividing the values in the bottom row by the values in the top row is always 4.

The height of the right circular cylinder shown below is 10 feet and its base has a radius of 4 feet. A. B. C. D.

poizon [28]

Answer:

502.4ft^3

Step-by-step explanation:

Given data

Height= 10ft

radius= 4 ft

Hence the volume for the cylinder can be gotten as

v= πr^2h

v= 3.14*4^2*10

v=3.14*16*10

v=502.4ft^3

Therefore the volume of the cylinder is 502.4ft^3

12x-9=10x-15 Help me answer this please

zvonat [6]

Answer:

x = -3

Step-by-step explanation:

Given:

12x - 9 = 10x - 15

Now, let's add 15 to both sides of the equation.

12x + 6 = 10x

Now, let's subtract 12x from both sides of the equation.

6 = -2x

Now, let's divide both sides by -2.

-3 = x

The radius of the base of a cylinder is increasing at a rate of 777 millimeters per hour. The height of the cylinder is fixed at

Tatiana [17]

Answer:

252π or 791.7 mm³/h

Step-by-step explanation:

The volume of a cylinder is given by

$V = \pi r^2h$

We desire to find the volume rate, that is, $\dfrac{dV}{dt}$

$\dfrac{dV}{dt} = \dfrac{dV}{dr}\cdot\dfrac{dr}{dt}$

dr/dt is the rate of change of the radius which is 7 mm/h.

dV/dr is derived by differentiating the volume equation, yielding

$\dfrac{dV}{dt} = 2\pi rh$

At r = 12 mm and h = 1.5 mm,

$\dfrac{dV}{dt} = 2\pi\times12\times1.5\times7 = 252\pi = 791.7$
