4/3⋅92−29=A cylindrical-shaped water tank has a diameter of 4 feet and is 12 feet tall. Which is closest to the volume of this t
Nookie1986 [14]

Answer:

Actual volume: 150.8

Step-by-step explanation:

the equation to find the volume of a cylinder is:

V= pi (r)^2 (h)

r= radius

h= height

To get the radius, you divide the diameter by 2.

when you plug in the numbers is looks like this:

V= pi (2)^2 (12)

you'll get 150.8 ft^3

I'm not really sure which volume would be the closest, but it should be around the answer I provided

WILL MARK BRAINLIEST! PLEASE HELP!
vodomira [7]

The formula y = mx + b sometimes appears with


different symbols.


For example, instead of x, we could use the


letter C. Instead of y, we could use the letter F.


Then the equation becomes


F = mC + b.


All temperature scales are related by linear


equations. For example, the temperature in


degrees Fahrenheit is a linear function of degrees Celsius.

Water freezes at: 0°C, 32°F


Water Boils at: 100°C, 212°F


Hope this helps!

If you doing straight-line depreciation rate

(P-s)÷N

(24000-18000)/5=1200

where p is cost, s is sold or salvage value, N is number of years

Un equipo de futbol esta compuesto por 13 personas, contando el entrenador y el masajista. Tras jugar un partido, reciben para t
AleksandrR [38]

Answer:

Ok, tenemos que el cheque es de 16_41.

Y también sabemos que podemos dividir este numero entre 13 personas, de acá podemos concluir que este numero es un múltiplo de 13.

Sea el dígito faltan igual a x

Sabemos que un numero es divisible por 13 cuando la suma de los productos de las  unidades, decenas, centenas,...  De dicho número  por los dígitos contenidos en la lista {1, –3, –4, –1, 3, 4 } (en ese orden) es  0  o múltiplo de 13.

Entonces, tenemos:

16x41:

1*1 + 4*(-3) + x*-4 + 6*-1 + 1*3 = 1 - 12 -4x - 6 + 3

=-14 - 4*x  

entonces, -14 - 4*x tiene que ser igual a 0, 13 o algún múltiplo de 13.

Como ambos términos son negativos, no podemos tener esta igualdad igual a 0 o a 13, entonces apuntamos por el siguiente múltiplo de 13 después de -13 (es decir, 13*-2 = -26)

-26 = -14 - 4*x

-26 + 14 = -4*x

-12 = -4*x

-12/-4 = 3 = x

Entonces nuestro dígito es igual a 3, y nuestro numero es:

16341.

Ahora podemos probar:

16241/13 = 1257

Es decir, cada miembro recibe 1257.
