a cylindrical tank has a radius of 15 feet and a height of 45 feet of water can tank hold

Answer:

The volume = 5 276.66928645188 cm³

Step-by-step explanation:

let V be the volume of the given sphere.

V = (4/3)×π×r³ ,where r is the radius of the sphere

r = 21.6÷2 = 10.8 cm

Then

V = (4÷3)×π×(10.8)³

   = 5 276.66928645188 cm³

All the options are incorrect. the required average is (3x-9)/2.

Thermometer A reads xº.
Thermometer B reads 2° below the reading on thermometer A = x-2
Thermometers C and D each read 4° less than twice the reading on thermometer  = 2(x-2)-4

Average of the values is the ratio of total sum of values to the number of values.

As per question,
A=x
B = x-2
C.D = 2(x-2)-4= 2x-8
Average = A + B + C + D /4
= x+x-2+2x-8+2x-8/4
= 6x-18/4
= 3x-9/2

Thus, the required average of temperature = 3x-9/2.

An equation is formed of two equal expressions. The sum of all possible values of x is 16.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

3x + 2y = 21

3x = 21 - 2y

x = (21-2y)/3

Since the value of x is needed to be positive, the value of 2y must not exceed 21. Also, the value of (21-2y) must be a multiple of two.

Now, the values of y that will satisfy the given condition in the equation are 0, 3, 6, and 9.

Further, the sum of the possible values of x are,

Sum = 7 + 5 + 3 + 1 = 16

Hence, the sum of all possible values of x is 16.

The least common multiple of 4 and 18 is 36.

A function assigns the value. The function f(g(x)) represents the amount that Sonia will earn per hour by baking bread.

A function assigns the value of each element of one set to the other specific element of another set.

Given f(x)=9x²+1 and g(x)=√(2x³). Therefore, the value of f(g(x)) will be,

[tex]f(g(x)) = 9(\sqrt{2x^3})^2 + 1[/tex]

            = 9(2x³) + 1

Answer:

  $7800

Step-by-step explanation:

The total interest earned can be found by summing the earnings from each of the investments.

Let x represent the total amount invested. Then Jessica's earnings are ...

  (x/2)(0.07) +(x/2)(0.13) = 780

Simplifying the equation gives ...

  (x/2)(0.07 +0.13) = 780

  0.10x = 780

  x = 7800 . . . . . . . . divide by 0.10

Jessica has $7800 invested.

Step-by-step explanation:

y = 4 and z = -2

Answer:

3081.24 cm³ (nearest hundredth)

Step-by-step explanation:

Formulas

[tex]\textsf{Circumference of a circle}=\sf 2 \pi r\quad\textsf{(where r is the radius)}[/tex]

[tex]\textsf{Volume of a cylinder}=\sf \pi r^2 h \quad\textsf{(where r is the radius and h is the height)}[/tex]

If a rectangular piece of paper is rolled along its length to form a cylinder:

To calculate the volume of the formed cylinder, determine the radius by using the circumference formula:

[tex]\implies \sf 2 \pi r = 44[/tex]

[tex]\implies \sf r = \dfrac{44}{2 \pi}[/tex]

[tex]\implies \sf r =\dfrac{22}{\pi}[/tex]

Substitute the round radius into the formula for Volume and solve for V:

[tex]\implies \sf V=\pi \left(\dfrac{22}{\pi}\right)^2(20)[/tex]

[tex]\implies \sf V=\pi \left(\dfrac{484}{\pi^2}\right)(20)[/tex]

[tex]\implies \sf V=\left(\dfrac{484}{\pi}\right)(20)[/tex]

[tex]\implies \sf V=\dfrac{9680}{\pi}[/tex]

[tex]\implies \sf V=3081.239698...cm^3[/tex]

Therefore, the volume of the cylinder is 3081.24 cm³ (nearest hundredth).
