Chau runs 10 miles in 58 minutes. How many minutes does he take per mile?

Answers

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.

A jazz concert brought in $119000 on the sale of tickets. If the tickets sold for and each, how many of each type of ticket were sold

Answers

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

3x+9=5x+21

What is x

Answers

Answer:

Simplifying
3x + 9 = 5x + 21

Reorder the terms:
9 + 3x = 5x + 21

Reorder the terms:
9 + 3x = 21 + 5x

Solving
9 + 3x = 21 + 5x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-5x' to each side of the equation.
9 + 3x + -5x = 21 + 5x + -5x

Combine like terms: 3x + -5x = -2x
9 + -2x = 21 + 5x + -5x

Combine like terms: 5x + -5x = 0
9 + -2x = 21 + 0
9 + -2x = 21

Add '-9' to each side of the equation.
9 + -9 + -2x = 21 + -9

Combine like terms: 9 + -9 = 0
0 + -2x = 21 + -9
-2x = 21 + -9

Combine like terms: 21 + -9 = 12
-2x = 12

Divide each side by '-2'.
x = -6

Simplifying
x = -6

God bless you and I hope this helps :)

Answer:

X = -6

1. 3x + 9 = 5x + 21

2. Subtract -5x from both sides

3x + 9 - 5x = 5x + 21 - 5x

3.-2x + 9 = 21

4. Subtract 9 from both sides

-2x + 9 - 9 = 21 - 9

5.-2x = 12

6. Divide both sides by -2

-2x/-2 = 12/-2

7. x= -6

The District Commissioner levies a fine of 200 bags of cowries for the crime, yet the messengers collect 250 bags from the villagers. Why

Answers

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).

The cost for Shania's groceries is $215. If the sales tax rate is 8%, how much will Shania pay for tax?

Answers

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

In a random sample of 60 computers, the mean repair cost was $150. Assume the population standard deviation is $36. Construct a 95% confidence interval for the population mean.

Answers

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

A cable is attached to a radio tower 100 ft
above the ground and forms an angle of 50 ( degrees ) with the ground. To the nearest foot, how long is the cable?

Answers

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
