Answer:

18u + 2 + 5/u - 8.

Step-by-step explanation:

(18u^2 - 142u - 11) ÷ (u - 8)

= 18u + 2 + 5/u - 8.

Answer:

10 feet.

Step-by-step explanation:

I am assuming this is a right triangle. We use Pythagoras theorem:

h^2 = 6^2 + 8^2

h^2 = 100

h = 10 feet.

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: 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 "=".

The 3rd answer

Step-by-step explanation:the

180-30\2

....

=75

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

HOPE THIS HELPED!! HAVE AN AWESOME DAY!

Step-by-step explanation:

1》 x + 74° = 90°

x = 90° - 74°

x = 16°

2》 x + 134° = 180°

x = 180° - 134°

x = 46°

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]

Step-by-step explanation:

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:  B. c = 22d

I'm gonna go with c=22d

Step-by-step explanation:  22d

C = 22d is the correct answer because for every day the cost increases by 22 so two days mean the cost is equal to 22 (2)

...............................................................................................................................................

Answer:

The equation that models the data in the table is:

Step-by-step explanation:

The table that represent the days and cost is given by:

      Days Cost

          2          44

          3          66

          5           110

          6          132

We see that the cost is a constant multiple of  the number of days.

i.e. the equation is given by:

            c=22d

i.e. the relationship is linear.

( Since, when d=2

we have: c=22×2=44

when d=3 we have:

c=22×3=66

and so on )

...............................................................................................................................................

You can see that 44/2 = 22

66/3 = 22

110/5 = 22

132/6 = 22

Then, the relation between C and d is a constant.

C/ d = 22

And you can model C as:

C = 22d.

This model tells that the cost equals 22 times the days.

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
