The given cylindrical
7nadin3 [17]

Answer:

30.54

Step-by-step explanation:

Here is the complete question used in answering this question

he given cylindrical container r =3 inches and height= 8in is used to fill the rectangular prism fish tank 24 , 24 and 12 inches with water. What is the least number of full cylindrical needed to completely fill the fish tank?

Number of cylinders needed = volume of prism / volume of cylinder

volume of prism = width x height x length = 24 x 24 x 12 = 6912

volume of a cylinder = nr^2h

n = 22/7

r = radius

(22/7) x (3^2) x 8 = 226.29

6912 / 226.29= 30.54

ivolga24 [154]

In a triangle, the sum of the interior angles is 180.

So, you have

A+B+C=180

Plug the values for angles A and C:

75+B+20=180 \iff 95+B=180 \iff B=180-95=85

Twenty times the square of a non-zero number is equal to 20 times the number ! What is the number ?
Shkiper50 [21]
X-the number

20 · x² = 20 · x    |divide both sides by 20

x² = x    |subtract x from both sides

x² - x = 0

x(x - 1) = 0 ⇔ x =0 or x - 1 = 0

Answer: x = 0 or x = 1

What is the transformation that occurs to the equation y=2^x if it changes to y=2^x-3
gizmo_the_mogwai [7]
     The parent function is: y = 2^x and it it transformed to: y = 2^x - 3. Both are exponential functions. First we can find the value of y, when x = 0.      For the 1st function:      y = 2^0 = 1      For the 2nd function:      y = 2^0 - 3 = 1 - 3 = - 2      We can conclude that the 2nd value of y is 3 units lower than the first.      Answer:      This transformation is translation 3 units down.
