Name a pair of complementary angles.PLSS HELP

A. angles BEA and CEB
B. angles FED and CED
C. angles EDF and BEA
D. angles AEB and BED

Step-by-step explanation:

(f o g)(x)

= f(x - 3)

= 2(x - 3) + 1 = 2x - 5.

Hence (f o g)(-2) = 2(-2) - 5 = -4 - 5 = -9.

Answer:

The tax paid by shania is $17.2

Step-by-step explanation:

The computation of the tax paid by shania is as follows:

= Cost of the shania groceries × sales tax rate

= $215 × 8%

= $17.2

by multiplying the cost of the shania groceries with the sales tax rate we can measured the tax paid by shania

hence, the tax paid by shania is $17.2

Hey, I'm not sure if I am right, but I hope it can create a spark or something.

8. Find x

10x - 1 = 14x - 37      Combine like terms

     +37        +37

10x + 36 = 14x          Combine like terms

-10x          -10x

    36 = 4x                Divide to isolate x

    36 = 4x

     4      4

    9 = x        

You can also do this method with the others.

PS: I am still not sure if this is the right method, lol. I just really want to help.

Answer:

The resulting percentage is seventy seven and seven ninths, or approximately 77.78%

Step-by-step explanation:

You can solve this by dividing 56 by 72 and multiplying by 100:

56 / 72 × 100

= 7 / 9 × 100

≅ 0.7778 × 100

≅77.78%

Answer:

Per mile Chau takes 5.8 minutes per mile.

Step-by-step explanation:

To find this answer you would have to do the amount of time divided by the amount of miles. Always remember when dividing time most of the time goes first unless the problem / instructions say differently. So, when you do 50 divided by 10 you will get 5.8. So, Chau takes 5.8 minutes per mile.

Answer:

L = 131 feet

Step-by-step explanation:

Right Triangles

The cable, the ground, and the radio tower form a right triangle with an angle of 90° located where the ground and the tower meet.

The cable is the hypotenuse of the triangle and the angle of 50° is opposite to the height of the radio tower.

To find the hypotenuse L we use the sine ratio:

[tex]\displaystyle \sin\theta=\frac{\text{opposite leg}}{\text{hypotenuse}}[/tex]

[tex]\displaystyle \sin 50^\circ=\frac{100}{L}[/tex]

Solving for L:

[tex]\displaystyle L=\frac{100}{\sin 50^\circ}[/tex]

Calculating;

L = 131 feet

Answer:

A. 0 and 4

Step-by-step explanation:

The x-intercepts are simply the values of x when y = 0. In other words it is the points where the line curve intercepts or cuts across the x-axis.

Form the graph given, we can see that at x = 0 and x = 4, the value of y = 0. Simply put, the curve cuts the x-axis at x = 0 and x = 4.

x-intercepts are 0 and 4.

Answer:

The 95% confidence interval for the population mean is between $140.89 and $159.11

Step-by-step explanation:

We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:

[tex]\alpha = \frac{1-0.95}{2} = 0.025[/tex]

Now, we have to find z in the Ztable as such z has a pvalue of [tex]1-\alpha[/tex].

So it is z with a pvalue of [tex]1-0.025 = 0.975[/tex], so [tex]z = 1.96[/tex]

Now, find the margin of error M as such

[tex]M = z*\frac{\sigma}{\sqrt{n}}[/tex]

In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample. So

[tex]M = 1.96\frac{36}{\sqrt{60}} = 9.11[/tex]

The lower end of the interval is the sample mean subtracted by M. So it is $150 - $9.11 = $140.89

The upper end of the interval is the sample mean added to M. So it is $150 + $9.11 = $159.11

The 95% confidence interval for the population mean is between $140.89 and $159.11

Answer:

Extra 50 bags were collected by the messengers.

Step-by-step explanation:

a) Number of bags of cowries levied as fine by the District Commissioner = 200 bags

Number of bags of cowries collected by the messengers = 250 bags

The difference or extra bags collected above the authorized fine = 50 (250 - 200)

b) The extra 50 bags could be bribes collected by the messengers to settle their own selfish interests.  They could also represent extras freely donated by the villagers for the messengers' trouble.  In the colonial days, when literacy levels were very low among the indigenous peoples of Africa and white men were in charge of governance, it was established that the black "middlemen," called interpreters or messengers, greatly exploited their own people through inflated and wrongful interpretations of fines, contrary to what was levied by the District Commissioners (DCs).

Answer:

6850 & 650

Step-by-step explanation:

The question is partly incomplete as it didn't state the cost of ticket sold. Also, it didn't state the total number of tickets sold. But, assuming that the tickets sold were $15 and $25 tickets, and the total number of tickets sold was 7500, then we say that

Let x = the number of $15 tickets sold

Let y = the number of $25 tickets sold

x + y = 7500 y = 7500 - x

15x + 25y = 119000

15x + 25(7500-x) = 119000

15x + 187500 - 25x = 119000

-10x = -68500

x = 68500 / 10

x = 6850 tickets at $15 each

Remember from the first calculation, we said x + y = 7500, then

y = 7500 - 6850

y = 650 tickets at $25 each

All you have to do is substitute the values I assumed for your given value. Thanks
