B. 112°

Step-by-step explanation:

4x -4 = (3x+4) + (2x-44)

4x -4 = 5x - 40

5x - 4x = -4 + 40

x = 36

∠BCA = 3 * 36 + 4 = 112

Answer:

−6cos(  π/3  t)+21

Step-by-step explanation:

The length of the accordion  is −6cos(  π/3  t)+21.

We must figure out the periodic phenomenon's amplitude, period, and vertical shift in order to create a sinusoidal function that models it. Additionally, we must choose between using a sine or a cosine function and calculate the ensuing phase shift.

Given

A = 5+1 = 6

Shift = 21

ω =- π/3[because of 4th quadrant]

exp = Asin[-ωt] + shift

      =-Acosωt + shift = -6cosπ/3 t + 21

Answer:

120 or 120%, hope this helps!

Step-by-step explanation:

Answer:

The first increase was of 60%.

Step-by-step explanation:

The initial value of the product is x.

The first increase was of y.

The second increase is of 25%, that is, 1.25.

The final price was double the original, so 2x.

This situation can be modeled by the following equation:

[tex]xy(1.25) = 2x[/tex]

We want to find y.

Simplifying by x

[tex]1.25y = 2[/tex]

[tex]y = \frac{2}{1.25}[/tex]

[tex]y = 1.6[/tex]

After the first increase, the value was 1.6 of the original value, that is a increase as a percent of (1.6 - 1)*100 = 60%.

Step-by-step explanation:

General line equation: y = mx + c, where m is the slope of the line and c is the y-intercept.

We have y = ax + b.

=> y - b = ax

=> y - b = a(x - 0).

The answer is option A.

Answer:

Danielle earns $1.20 more than Mackenzie (per hour)

Step-by-step explanation:

To find out how much money per hour each person earns, you would divide the earinings by the number of hours;

Danielle: $36.80/4 = $9.20 per hour

MackKenzie: $50.40/6 = $8.40 per hour

To find out how much extra Danielle earns, you would subtract 8.40 from 9.20;

9.40 - 8.20 = $1.20

Thus, Danielle earns $1.20 more than Mackenzie per hour.

Answer:

Your answer is going to be a=1

Step-by-step explanation:

First things first, we want all the letters on the left side and all the numbers on the right side. So, you have to get rid of the three. In order to get rid of the three you have to take it away, so A/5=8-3. Then it will become A/5=5. After that you want to have A all by itself so divide it by 5, A/5=5/5. Then it will become A=1. Hope this helps! :)

Answer:

The probability that the person will not  be a senior

P(E⁻) = 1 - P(E)

       =  [tex]1- \frac{5}{9} = \frac{4}{9}[/tex]

Step-by-step explanation:

Explanation:-

Given A high school club has 10 members who are seniors and 8 members who  are juniors

n(S) = 10 + 8 = 18

If a member is randomly selected to be the club president

Let 'E' be the event that the person will  be a senior

The probability that the person will  be a senior

      [tex]P(E) = \frac{n(E)}{n(S)}[/tex]

     [tex]P(E) = \frac{n(E)}{n(S)} = \frac{10}{18} = \frac{5}{9}[/tex]

The probability that the person will not  be a senior

P(E⁻) = 1 - P(E)

       =  [tex]1- \frac{5}{9} = \frac{4}{9}[/tex]
