what is 2/3 ÷ 4/5

2/3
5/6
1 1/5
3 1/3​

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:

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:

1. D= 46 degrees

2. X= 50 degrees

3. X= 180-118 = 62 degrees

4. X = 90-75 = 15 degrees.

Step-by-step explanation:

Answer:

Going by the order from the first row left to right and then second row left to right

1) D=46

2) x=62

3) x=50

4) x=15

5) b=40

Step-by-step explanation:

So for the first column for the first question its a complementary angle which means 2 or more angles added up to from a 90 degrees angle. We got 44 degrees already and an unknown angle which will lead to 90-44= 46 and that 46 degrees is your answer. D will be equal to 46.

For the second question on the first column, you have 2 angles forming a straight line. This is a s upplementary angle which means 2 or more angles added up to from 180 degrees. You have 1 angle already which is 118 and to find the other angle, 180-118 which will be 62. X will equal to 62

For the thrid question which is the first question on the SECOND column, you have another supplementary angle. You have 130 and 180-130=50 and X will equal to 50.

For the 4th question you have a complementary and one angle is 75. You do 90-75 and get 15. X will equal to 15.

The last question which is the huge rectangle on the right, you have 2 intersecting lines. We know one side is 40. Well the only thing that makes sense here is B=40 since its vertical to the one angle given. Vertical angles are equal so therfore the answer is b=40

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

9d=67-4

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

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:

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%

Answer:

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,

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: $0.10 per fluid ounce

Step-by-step explanation:

Kayla bought two-pints for $3.20.

First convert this quantity to fluid ounces.

1 pint = 16 fluid ounces

If 2 pints were bought therefore, this would be:

= 2 * 16

= 32 fluid ounces

32 fluid ounces cost $3.20.

Cost per fluid ounce is therefore:

= 3.20 / 32

= $0.10 per fluid ounce

Answer:

$0.10 per fluid ounce
