Answer:

37.68

Step-by-step explanation:

Circumference = Diameter x pi

Diameter = 12 feet

12 x 3.14 = 37.68

The circumference of the pool is 37.68 feet.

Answer:

17.6

Step-by-step explanation:

If you add all of the digets up you get: 86

86 divided by the quanity of numbers is: 17.6

Answer:

32

Step-by-step explanation:

Pythagorean theorem

[tex]a^{2} + b^{2} =c^{2}[/tex]

a = perpendicular

b = base

c = hypotenuse

we have to find the hypotenuse

so,

[tex]13^{2} + 29.25^{2} = c^{2} \\169 + 855.6 = c^{2}\\1024.6 = c^{2}\\\sqrt{1024.6} = \sqrt{c^{2}} \\c = 32[/tex]

Answer:

2.8

14 divided by 5 will tell you how many recipes you can make

Answer:

Vertical angles: <3 and <8, <2 and <5, <1 and <6, <4 and <7 (choose one pair, these are all right)

Linear: <1 and <5, <2 and <6, <3 and <7, <4 and <8, there are more (choose one pair, all these are right)

Congruent: Choose one of the vertical angle pairs I listed above

Step-by-step explanation:

Vertical angles are diagonally across for each other and equal the same angle. You would get a better explanation if you looked up pictures.  

Linear angles are two angles on a straight line that are divided by another line. Again, you would get a better explanation by looking at a visual

Congruent angles are equal to each other, and because there are no angle measures here, you would go with a vertical angle pair.

Answer:

Step-by-step explanation:

Vertical angles: <3 and <8, <2 and <5, <1 and <6, <4 and <7 (choose one pair, these are all right)

Linear: <1 and <5, <2 and <6, <3 and <7, <4 and <8, there are more (choose one pair, all these are right)

Congruent: Choose one of the vertical angle pairs I listed above

Answer:

9

Step-by-step explanation:

V=pi (r squared) (h/3)

75pi = 25pi (h/3)

Divide both sides by 25 pi

3= h/3

Multiply both sides by 3

h=9

Answer:aw ehtI Belive its 7 i could be wrong though

Step-by-step explanation:

the way you would solve this is u would arange the numbers like small to greatest then count how many there are and there happends to be 15 then you find the middle.

d=63/9

d=7

Answer:

d = 7

Step-by-step explanation:

9d + 4 = 67

9d = 67 - 4

9d = 63

9d ÷9 = 63 ÷ 9

d = 7

Answer:

99.7% of the boys are between 54 and 84 inches tall.

Step-by-step explanation:

The heights 54 and 84 inches are 3 standard deviations away from the mean. Thus, 99.7% of the boys are between 54 and 84 inches tall.

The percentage of the boys are between 54 and 84 inches tall is 99.7%

What is percentage?

Percentage a relative value indicating hundredth parts of any quantity.

What is empirical rule?

The empirical rule or  the three-sigma rule , is a statistical rule which states that for a normal distribution, almost all observed data will fall within three standard deviations of the mean.

The empirical rule predicts that 68% of observations falls within the first standard deviation (µ ± σ), 95% within the first two standard deviations (µ ± 2σ), and 99.7% within the first three standard deviations (µ ± 3σ).

From question mean(μ) = 69 in. and  standard deviation(σ)= 5 in.

(µ ± σ) = (69 ± 5)

           =64 - 74

           =68%

(µ ± 2σ) =(69 ± 10)

            =59 -79

            =95%

(µ ± 3σ) =(69 ± 15)

             =54 -84

             = 99.7%

Thus the percentage of the boys are between 54 and 84 inches tall is 99.7%

Given:

The value is [tex]\dfrac{\sqrt{2}}{2}[/tex].

To find:

The values from the given options which are equal to the given value.

Solution:

We have,

[tex]\dfrac{\sqrt{2}}{2}[/tex]

It can be written as:

[tex]\dfrac{\sqrt{2}}{2}=\dfrac{1}{\sqrt{2}}[/tex]

From the standard trigonometric table, we get

[tex]\sin 30^\circ=\dfrac{1}{2}[/tex]

[tex]\sin 45^\circ=\dfrac{1}{\sqrt{2}}[/tex]

[tex]\cos 45^\circ=\dfrac{1}{\sqrt{2}}[/tex]

[tex]\cos 60^\circ=\dfrac{1}{2}[/tex]

[tex]\tan 30^\circ=\dfrac{1}{\sqrt{3}}[/tex]

[tex]\tan 45^\circ=1[/tex]

From the above values it is clear that the value of [tex]\sin 45^\circ [/tex] and [tex]\cos 45^\circ [/tex] are equal to [tex]\dfrac{1}{\sqrt{2}}[/tex].

Therefore, [tex]\sin 45^\circ [/tex] and [tex]\cos 45^\circ [/tex] and equal to [tex]\dfrac{\sqrt{2}}{2}[/tex]. So, options B and C are correct.

Answer:

x = 6

Step-by-step explanation:

Tip: You want to isolate the x-variable on one side of the equation to find its value.

1) First, get rid of the radical signs on both sides of the equation by squaring both sides. This should leave you with 5x-7 = 3x+5.

2) Get the x-variables on one side by subtracting 3x from both sides, so the equation should be 2x-7=5.

3) Solve for x by adding 7 to both sides, so that your equation looks like this: 2x = 12.

4) Divide both sides by 2 and you will get x = 6. You can verify 6 as the x-value by plugging 6 back into the original equation.

I hope that helps! :)

Answer:

B 4

Step-by-step explanation:

Can A is 8 x 8π, or 64π, where the radius 4 was multiplied by 2 to get diameter and then by π to get length of can.

Can B is 4 x 4π, or 16π, where the radius of 2 is multiplied by 2 to get diameter and then by π to get length of can.
