Answer:

[tex]Longer\ leg = 8[/tex]

Step-by-step explanation:

Given

30-60-90 triangle

[tex]Shorter = \frac{8}{\sqrt 3}[/tex]

Required

The longer leg

The following relationship exists in a 30-60-90 triangle.

[tex]Longer\ leg = \sqrt 3 * Shorter\ Leg[/tex]

This gives:

[tex]Longer\ leg = \sqrt 3 * \frac{8}{\sqrt 3}[/tex]

[tex]Longer\ leg = 1* \frac{8}{1}[/tex]

[tex]Longer\ leg = 1* 8[/tex]

[tex]Longer\ leg = 8[/tex]

Answer:

9/5

Step-by-step explanation:

The common difference = 6 - 2 = 4

The age after 6 is 6 + 4 = 10 = y

The age after 14 is 14 + 4 = 18 = z

z/ y = 18/10 = 9/5

Step-by-step explanation:

1》 x + 74° = 90°

x = 90° - 74°

x = 16°

2》 x + 134° = 180°

x = 180° - 134°

x = 46°

30+2*75=

...

180

Answer:

30 + 2x = 180

Step-by-step explanation:

This is becuase we know this triangle is an isosceles triangle. (The two markings on the sides prove that.) An isosceles triangle is when two sides (so naturally also two angles) are the same. This means the other angle is x. We know that if we add all of the angles, we'll get 180. So, 30 + x + x = 180 or "30 + 2x = 180".

Also, x = 75.

Here:

30 + 2x = 180

30 - 30 + 2x = 180 - 30

2x = 150

2x / 2 = 150 / 2

x = 75

Answer:

[tex]m(x)_A = 5.2[/tex] --- Mean absolute deviation of educational documentary

[tex]m(x)_B = 4.7[/tex] --- Mean absolute deviation of prime time drama

Step-by-step explanation:

Given

[tex]n = 10[/tex]

See attachment for table

Required

Determine the mean absolute deviation of each

Mean absolute deviation m(x) is calculated as:

[tex]m(x) = \frac{1}{n}\sum |x - \mu|[/tex]

For Educational Documentary

First, calculate the mean

[tex]\mu = \frac{\sum x}{n}[/tex]

So:

[tex]\mu_A = \frac{26 + 28 + 30 + 18+27 + 18 + 20 +31+17+17}{10}[/tex]

[tex]\mu_A = \frac{232}{10}[/tex]

[tex]\mu_A = 23.2[/tex]

The mean absolute deviation is then calculated as:

[tex]m(x)_A = \frac{1}{n}\sum |x - \mu_A|[/tex]

[tex]m(x)_A = \frac{1}{10}(|26 -23.2| +|28 -23.2| +|30 -23.2| +|18 -23.2| +|27 -23.2| +|18 -23.2| +|20 -23.2| +|31 -23.2| +|17 -23.2| +|17 -23.2|)[/tex]

[tex]m(x)_A = \frac{1}{10}(|2.8| +|4.8| +|6.8| +|-5.2| +|3.8| +|-5.2| +|-3.2| +|7.8| +|-6.2| +|-6.2|)[/tex]

[tex]m(x)_A = \frac{1}{10}(2.8 +4.8 +6.8 +5.2 +3.8 +5.2 +3.2 +7.8 +6.2 +6.2)[/tex]

[tex]m(x)_A = \frac{1}{10}*52[/tex]

[tex]m(x)_A = 5.2[/tex]

For Prime time Drama

First, calculate the mean

[tex]\mu = \frac{\sum x}{n}[/tex]

So:

[tex]\mu_B = \frac{39+39+35+29+40+27+41+29+32+30}{10}[/tex]

[tex]\mu_B = \frac{341}{10}[/tex]

[tex]\mu_B = 34.1[/tex]

The mean absolute deviation is then calculated as:

[tex]m(x)_B = \frac{1}{n}\sum |x - \mu_B|[/tex]

[tex]m(x)_B = \frac{1}{10}(|39-34.1|+|39-34.1|+|35-34.1|+|29-34.1|+|40-34.1|+|27-34.1|+|41-34.1|+|29-34.1|+|32-34.1|+|30-34.1|)[/tex]

[tex]m(x)_B = \frac{1}{10}(|4.9|+|4.9|+|0.9|+|-5.1|+|5.9|+|-7.1|+|6.9|+|-5.1|+|-2.1|+|-4.1|)[/tex]

[tex]m(x)_B = \frac{1}{10}(4.9+4.9+0.9+5.1+5.9+7.1+6.9+5.1+2.1+4.1)[/tex]

[tex]m(x)_B = \frac{1}{10}*47[/tex]

[tex]m(x)_B = 4.7[/tex]

Answer:

x = 55

Step-by-step explanation:

A triangle is 180 degrees in total. All you have to do is add the sides you already have and subtract that by 180.

Answer:

x = 6

Step-by-step explanation:

7x - 2 = 40

7x - 2 + 2 = 7x

40 + 2 = 42

7x = 42

7x / 7 = x

42 / 7 = 6

x = 6

The correct answer is C. (2, 3)

Answer: it would be the "=" sign

Step-by-step explanation: this is because 2/3 and 6/9 are equivalent fractions. you want to find the greatest common factor between 6 and 9 which is 3. you multiply that by the numerator and denominator. therefore, the symbol that compares these mixed numbers is "=".

Answer:

The complete table is

d               t

1               3

3              9

5              15

Step-by-step explanation:

Here is the correct and complete question:

The total number of hours, t, that Trent has practiced his guitar after d days is modeled by the equation t = 3d.

Complete the table below.

d               t

1

3

               15

Step-by-step explanation:

For the first space, we are to determine the value of t when d is 1

From the given equation, t = 3d, put d = 1 and determine t

t = 3d

∴ t = 3(1) = 3×1

t = 3

For the second space , we are to determine the value of t when d is 3

Put d = 3 in the equation to determine t

t = 3d

∴ t= 3(3) = 3×3

t = 9

For the third space, we are to determine the value of d when t is 15.

Put t = 15 in the equation and then find d

t = 3d

∴ 15 = 3d

Divide both sides by 3

15/3 = 3d/3

5 = d

∴ d = 5

Answer:

104°

Step-by-step explanation:

The straight line for [tex]q[/tex] forms an angle of 180°

Therefore,

[tex]x+y=180[/tex]

[tex]x+76=180[/tex]

[tex]x=180-76[/tex]

[tex]x=104[/tex]

Answer: The answer is 8 lb for $18.80

That is the answer because you have to divide in order to see which is the best buy

You have to divide $4.98 by 2lb and you will get 2.49, divide $12.25 by 5lb which equals 2.45, divide $18.80 and you will get 2.35, divide $23.70 by 10lb and you will get 2.37. So therefore you answer is C.8lb for $18.80 because 2.35 is better than the other deals.

Answer:

Step-by-step explanation:

gracias por los puntos

Step-by-step explanation:

the total angles of the triangle are 180°

so,

180° = (x - 10) + (2x + 5) + 35°

180° - 35° = (x - 10) + (2x + 5)

145° = 2x + x + 5 - 10

145° = 3x - 5

145° + 5 = 3x

150° = 3x

150/3 = x

x = 50
