32 athletes are going camping for the weekend.
3 athletes can sleep in one tent.
We have to find the minimum number of tents.
What is Number system?
A system of writing to express number is called Number system.
Now,
Number of athletes = 32
Number of athletes in one tent = 3
Hence, Minimum number of tents = 32 ÷ 3
We get 11 tents for 32 athletes.
Therefore, Minimum number of tents are 11.

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
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
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?
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

Angle ABC is taken by a dilation with the center P and scale factor 3 to angle A'B'C'
The measure of angle ABC is 21 degrees. What is the measure of angle A'B'C'?
Answer: 21
Step-by-step explanation: We are given that angle ABC is dilated with center P.
Scale factor=3
Angle A'B'C' is formed after dilation of angle ABC.
Dilation: when a figure is dilated by scale factor a then, the figure shape does not change.
After dilation, the size of figure changes.
The initial figure and the figure obtained after dilation are similar in shape.
When two figures are similar then , the angles of one figure are congruent to its corresponding angles in other figure and ratio of their corresponding sides are equal.
The measure of angle ABC=21'
After dilation by scale factor 3 then, the measure of angle A'B'C' remains=21'
Because the shape does not change in dilation transformation.
PLEASE ANSWER THIS QUESTION RIGHT Name the x-intercept(s)?
A:0 and 4,B:2,C:4,D:0.
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.

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

The cost for Shania's groceries is $215. If the sales tax rate is 8%, how much will Shania pay for tax?
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
The District Commissioner levies a fine of 200 bags of cowries for the crime, yet the messengers collect 250 bags from the villagers. Why
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).

Mr. Hammond is the volunteer coordinator for a company that puts on running races. Last year, the company organized 7 short races and 8 long races, which required a total of 804 volunteers. This year, the company organized 11 short races and 5 long races, which required 688 volunteers in total. How many volunteers does each type of race require?
Answer:
28 short race volunteers
76 long race volunteers
Step-by-step explanation:
Let :
Short races = a
Long races = b
LAST YEAR:
7a + 8b = 804 - - - - (1)
THIS YEAR:
11a + 5b = 688 - - - (2)
Multiply (1) by 5 and (2) by 8
35a + 40b = 4020
88a + 40b = 5504
Subtract
-53a = - 1484
a = 1484 / 53
a = 28
Put a = 28 in equation (1)
7(28) + 8b = 804
196 + 8b = 804
8b = 804 - 196
8b = 608
b = 76
28 short race volunteers

Find the composition (fog)(-2) for the functions f(x) = 2x + 1 and g(x) = x- 3.
Show work
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.
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.
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
