Percy is filling a cylindrical tank with water. The tank is
9 meters high and has a base area of 78 square meters.
The hose he is using fills the tank at a rate of 6 cubic
meters in one minute. How long will it take Percy to fill
the tank?
A. 13 min
B. 117 min
C. 52 min
D. 468 min

Answer:

21 square feet

Step-by-step explanation:

To find out the area of this irregular figure, divide it into two rectangles and add their areas.. This can be done in two ways.

Version 1: 6 * 2 rectangle and 3 * 3 square

(6 * 2) + (3 * 3)

12 + 9

21 sq. ft.

Version 2: 5 * 3 rectangle + 2 * 3 rectangle

(5 * 3) + (2 * 3)

You could really just do 7 * 3 here.

7 * 3

21 sq. ft.

Either way, you still get 21 square feet as your answer.

Step-by-step explanation:

Answer:

Step-by-step explanation:

In order to calculate the volume of a triangular prism you need 2 things:

The triangles area and the prism's height.

Any prism's volume can be calculated by multiplying its base area with its height.

The Area of a triangle can be calculated in different ways.

The most used and "normal" way is:

(width * height) / 2

Another way is by using herons formula, which looks like this:

a, b, c = different sides of the triangle (length)

s = (a + b + c) / 2

a = [tex]\sqrt{s (s-a)(s-b)(s-c)}[/tex]

When you have the prism's base area ([tex]b_{a}[/tex]) you just have to multiply:

[tex]b_{a}*h=V[/tex]

(V = volume)

Answer:

Step-by-step explanation:

g circle g (x) has the meaning of putting g(x) on the right wherever you see an x in the original question

gcircle g (x) = 4(g(x)) + 1

g circle g(x) = 4(4x + 1) + 1

g circle g(x) = 16x + 4 + 1

g circle g(x) = 16x+5

All of them form a right triangle.

Step-by-step explanation:

Khan

Answer:

39

Step-by-step explanation:

If i'm right, a triangle should add up to 180, so you add 39 and 102 to get 141. Then you subtract 141 from 180 and get 39

Answer:

39

Step-by-step explanation:

Remark

Every triangle has 180 degrees. The three angles must add to 180

Solution

x + 102 + 39 = 180

x + 141 = 180                     Subtract 141 from both sides.

x + 141-141 = 180-141

x = 39

Answer:

B. 8x + 56

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

The answer is that it would take 8 hours for the temperature to drop down to 36 degrees.

1.5x8=12

1x8=8 and 0.5x8=4

In 8 hours the temperature will be 36°F from 48°F.

An equation is written in the form of variables and constants separated by the operation of multiplication and division,

An equation states that terms in different forms on both sides of the equality sign are equal.

Multiplication and division do not separate the terms of an equation.

Given, The current temperature is 48 degrees Fahrenheit it is expected to drop 1.5 degrees each hour.

Assuming the no. of hours to be x.

∴ 36 = 48 - 1.5x.

- 1.5x = - 12.

x = 8.

Answer:

+12.5%

Step-by-step explanation:

This is rather simple. Subtract 72 from 81, then put the difference over 72. Then, multiply that by 100.

(81 - 72)/72 * 100

Subtract 72 from 81 to get 9

9/72 * 100

Multiply 9 by 100 to get 900

900/72

Simplify the above fraction by cancelling out 9.

100/8

Divide 100 by 8 to get 12.5%

Answer:

The length of the AR is  [tex]3\sqrt{17}[/tex]  or [tex]12.4[/tex] units.

Step-by-step explanation:

Given the endpoints of a line segment AR

We can calculate the length of AR using the formula

[tex]L_{AB}=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}[/tex]

In our case,

Substituting (x₁, y₁) = (8, -2) and (x₂, y₂) = (-4, 1) in the formula

[tex]L_{AB}=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}[/tex]

        [tex]=\sqrt{\left(-4-8\right)^2+\left(1-\left(-2\right)\right)^2}[/tex]

        [tex]=\sqrt{\left(-4-8\right)^2+\left(1+2\right)^2}[/tex]            ∵ Apply rule:  [tex]-\left(-a\right)=a[/tex]

        [tex]=\sqrt{12^2+3^2}[/tex]

        [tex]=\sqrt{144+9}[/tex]

        [tex]=\sqrt{153}[/tex]

        [tex]=\sqrt{9\times 17}[/tex]

         [tex]=\sqrt{17}\sqrt{3^2}[/tex]          Apply radical rule:   [tex]\sqrt[n]{ab}=\sqrt[n]{a}\sqrt[n]{b}[/tex]

         [tex]=3\sqrt{17}[/tex]              Apply radical rule:   [tex]\sqrt[n]{a^n}=a[/tex]

         [tex]=12.4[/tex]

Therefore, the length of the AR is  [tex]3\sqrt{17}[/tex]  or [tex]12.4[/tex] units.
