Answer:

4939.22 feet cubed.  

Step-by-step explanation:

The formula for the volume of a cylinder is V=3.14*r^2*h

First we square the raidus, which is 11 in this problem.  11 squared is 121.

Next we multiply everything together.

3.14*121 is 379.94.  Then, 379.94 * the height, which is 13, is 4939.22.

Since our answer is already rounded to the nearest hundredth, the answer to this problem is 4939.22

Answer:

120 degrees

Answer:

43.8 is the Area but i don't know about the perimeter

Step-by-step explanation:

Answer:

are = 40.2, perimeter = 28.2

Step-by-step explanation:

perimeter = 6+6(blue triangle)+3(pink triangle)+4.2+3 (green parallelogram) +3+3 (purple square) = 28.2

area =

6 * 6 * 1/2 = 18 blue triangle

3*3*1/2 = 4.5 pink triangle

3*3 = 9 purple square

3*2.9 = 8.7 green parallelogram

= 8.7+9+4.5+18 = 40.2

Answer:

[tex](b)\ P(Green) = \frac{3}{8} ; P(Yellow) = \frac{1}{8}[/tex]

[tex](c)\ P(Green) = \frac{1}{4} ; P(Yellow) = \frac{1}{4}[/tex]

Step-by-step explanation:

Given

[tex]P(Red) = \frac{2}{7}[/tex]

[tex]P(Blue) = \frac{3}{14}[/tex]

Required

Which completes the model

Let the remaining probability be x.

Such that:

[tex]P(Red) + P(Blue) + x = 1[/tex]

Make x the subject

[tex]x = 1 - P(Red) - P(Blue)[/tex]

So, we have:

[tex]x = 1 - \frac{2}{7} - \frac{3}{14}[/tex]

Solve

[tex]x = \frac{14 - 4 - 3}{14}[/tex]

[tex]x = \frac{7}{14}[/tex]

[tex]x = \frac{1}{2}[/tex]

This mean that the remaining model must add up to 1/2

[tex](a)\ P(Green) = \frac{2}{7} ; P(Yellow) = \frac{2}{7}[/tex]

[tex]P(Green) + P(Yellow)= \frac{2}{7} + \frac{2}{7}[/tex]

Take LCM

[tex]P(Green) + P(Yellow)= \frac{2+2}{7}[/tex]

[tex]P(Green) + P(Yellow)= \frac{4}{7}[/tex]

This is false because: [tex]\frac{4}{7} \ne \frac{1}{2}[/tex]

[tex](b)\ P(Green) = \frac{3}{8} ; P(Yellow) = \frac{1}{8}[/tex]

[tex]P(Green) + P(Yellow)= \frac{3}{8} + \frac{1}{8}[/tex]

Take LCM

[tex]P(Green) + P(Yellow)= \frac{3+1}{8}[/tex]

[tex]P(Green) + P(Yellow)= \frac{4}{8}[/tex]

[tex]P(Green) + P(Yellow)= \frac{1}{2}[/tex]

This is true

[tex](c)\ P(Green) = \frac{1}{4} ; P(Yellow) = \frac{1}{4}[/tex]

[tex]P(Green) + P(Yellow)= \frac{1}{4} + \frac{1}{4}[/tex]

Take LCM

[tex]P(Green) + P(Yellow)= \frac{1+1}{4}[/tex]

[tex]P(Green) + P(Yellow)= \frac{2}{4}[/tex]

[tex]P(Green) + P(Yellow)= \frac{1}{2}[/tex]

This is true

Other options are also false

Hope this helped, good luck! :)

Answer:

y=-9/7x-15/14

Step-by-step explanation:

Slope-intercept form is y=mx+b

The y-coordinate is on one side, and the slope, x-coordinate, and y-intercept are on the other side.

18x+14y+15=0

-15              -15

18x+14y=-15

-18x       -18x

14y=-15-18x

14y=-18x-15

÷14        ÷14

y=-9/7x-15/14

Here is the asnwer.....

Answer:

(12x + 19) + (22x - 9) = 180°, x = 5

Step-by-step explanation:

Supplementary angles are 2 angles that adds up to 180°

Another words,

(12x + 19) + (22x - 9) = 180°

Now we solve for x by combining like terms:

34x + 10 = 180°

Subtract 10 on both sides:

34x = 170°

Divide 34 on both sides:

x = 5

Answer:

sd sad a

Step-by-step explanation:

Answer:

x = 20

Step-by-step explanation:

Use Pythagorean Theorem to solve for x:

a^2 + b^2 = c^2

Plug in given values if a = 12, b = 16, and c = x (x is hypotenuse)

12^2 + 16^2 = x^2

(12*12) + (16*16) = x^2

144 + 256 = x^2

400 = x^2

Take square root of both sides to solve for x

sqrt(400) = sqrt(x^2)

20 = x or x = 20
