Volume formula of the cylinder (tank is cylindrical, assumed from the given)

V = Area of base × height of prism
V = \pir²h
V = \pi(18.8)² × 24
V = 353.44\pi × 24
V = 8482.56\pi ft³ (in terms of \pi)
V = 26,648.74818 ft³
V ≈ 26,648.75 ft³

I need help I got this wrong
wlad13 [49]
<h2>Solution : </h2>

y = -2|x +1|

→ |x + 1| = -y/2

→ x+1 = y/2

and

x + 1 = -y/2

→ x + 1 belongs to R

→ x belongs to R

Domain = R

Range = y = -2(R)

→( -∞ , 0)

Solve the right triangle ABC with right angle C, if B=30 degrees, and C = 10
iren2701 [21]

Answer:

The answer to your question is letter D

Step-by-step explanation:

We know that the sum of the internal angles in a triangle equals 180°.

So, B = 30°, C = 90° and A = ?

                      A + B + C = 180°

Substitution

                      A + 30 + 90 = 180

Solve for A

                     A = 180 - 30 - 90

                     A = 180 - 120

                    A = 60°

To find "b". use the trigonometric function sine

sin B = \frac{opposite side}{hypotenuse}

sin B x hypotenuse = Opposite side

Opposite side = sin 30 x 10

Opposite side = 0.5 x 10

Opposite side = b = 5.0                          

To find "a" use the trigonometric function cosine

Cos A = adjacent side / hypotenuse

Adjacent side = a = cos A x hypotenuse

Adjacent side = a = cos 60 x 10

                          a = 0.866 x 10

                         a = 8.66

The sum of two numbers is 50 and the difference is 12. What are the numbers?
Strike441 [17]

Answer:

The two numbers are 31 and 19

Step-by-step explanation:

Let x and y be the numbers

x+y = 50

x-y = 12

Add the two equations together

x+y = 50

x-y = 12

-----------------

2x +0y = 62

Divide by 2

2x/2 = 62/2

x = 31

Now find y

31+y = 50

Subtract 31

y = 50-31

y = 19
