The water supply uses huge concrete pipes to drain stormwater.
a Find the external radius of a pipe.
b Find the Internal radius of a pipe.
c Find the volume of concrete necessary to make one pipe.
Answer:
a. External radius is 0.5 m.
b. Internal radius is 0.45 m.
c. Volume of concrete necessary to make one pipe is 0.37 [tex]m^{3}[/tex].
Step-by-step explanation:
a. It can be observed that the diameter of the pipe is 1 m.
External radius = [tex]\frac{diameter}{2}[/tex]
= [tex]\frac{1}{2}[/tex]
= 0.5
External radius = 0.5 m
b. Internal radius of the pipe can be determined by;
Internal radius = [tex]\frac{internal diameter}{2}[/tex]
But,
Internal diameter = 1 m - (2 x 0.05 m)
= 1 m - 0.10 m
= 0.9 m
Internal diameter = 0.9 m
So that,
Internal radius = [tex]\frac{0.9}{2}[/tex]
= 0.45
Internal radius = 0.45 m
c. Volume of concrete required = [tex]\pi[/tex][tex]r_{e} ^{2}[/tex]h - [tex]\pi[/tex][tex]r_{i} ^{2}[/tex]h
where [tex]r_{e}[/tex] is the external radius, and [tex]r_{i}[/tex] is the internal radius.
Volume of concrete required = [[tex]\frac{22}{7}[/tex] x [tex](0.5)^{2}[/tex] x 2.5] - [[tex]\frac{22}{7}[/tex] x [tex](0.45)^{2}[/tex] x 2.5]
= 1.9643 - 1.5911
= 0.3732
The volume of concrete necessary to make one pipe is 0.37 [tex]m^{3}[/tex].

a small town buys a total of 35 books that cost $1022. Some of the books cost $22 each, and the remainder cost $34 per book. How many books of each price did they get
Answer:
They got 14 books at $22 and 21 books at $34.
Step-by-step explanation:
From the information given, you can write the following expressions:
x+y=35 (1)
22x+34y=1022 (2), where:
x is the number of books that cost $22
y is the number of books that cost $34
First, you can solve for x in (1):
x=35-y (3)
Then, you can replace (3) in (2) and solve for y:
22(35-y)+34y=1022
770-22y+34y=1022
12y=1022-770
12y=252
y=252/12
y=21
Finally, you can replace the value of y in (3) to find x:
x=35-y
x=35-21
x=14
According to this, the answer is that they got 14 books at $22 and 21 books at $34.

Leanne has an assignment where she is required to name something that qualifies as nonmaterial culture. What would BEST demonstrate this concept?
A. the belief that no one should kill another person
B. the lyrics to a song on the Internet
C. clothing that was made by a local craftswoman
D. a cell phone app that helps people find a friend
Answer:
A.
Step-by-step explanation:
The best option that would demonstrate this concept would be the belief that no one should kill another person. This is because out of all the available options this is the only intangible "material" that actually affects a population's culture. Such a belief or idea would make a population create their entire culture around such a belief as well as the other thoughts and ideas that define what is write and wrong to a culture.

Find the Quetion of the line that passes through the points (1,6) and (5,2)
Answer:
[tex]y=-x+7[/tex]
Step-by-step explanation:
Equation of straight line is given as
[tex]y-y_1=m(x-x_1)[/tex]
where slope m is calculated as
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Here
[tex](x_1, y_1)=(1, 6) \ \ and \ \ (x_21, y_2) = (5, 2)[/tex]
[tex]m = \frac{2 - 6}{5 - 1}\\m=\frac{- 4}{4} \\m=-1[/tex]

Answer:
x = 10 yd
Explanation:
These triangles are based on proportions. 12 yd is proportional to 18 yd, and x yd to 15 yd. We want to find x. We'll use the rule of three to calculate the unknown number.
12/18 = x/15
x = (12 · 15)/18
x = 10 yd (10 yards from the hut to the gold coins)

On average, Colby has noticed that 21 trains pass by his house daily (24 hours) on the nearby train tracks. What is the probability that at most 6 trains will pass his house in a 12-hour time period
Answer:
10.16% probability that at most 6 trains will pass his house in a 12-hour time period
Step-by-step explanation:
We are dealing with the mean during a period of time, so we use the Poisson distribution to solve this question.
In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:
[tex]P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}[/tex]
In which
x is the number of sucesses
e = 2.71828 is the Euler number
[tex]\mu[/tex] is the mean in the given interval.
Colby has noticed that 21 trains pass by his house daily (24 hours)
We are working with 12 hour periods(half of 24), so [tex]\mu = \frac{21}{2} = 10.5[/tex]
[tex]P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}[/tex]
What is the probability that at most 6 trains will pass his house in a 12-hour time period
[tex]P(X \leq 6) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5) + P(X = 6)[/tex]
So
[tex]P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}[/tex]
[tex]P(X = 0) = \frac{e^{-10.5}*(10.5)^{0}}{(0)!} = 0[/tex]
[tex]P(X = 1) = \frac{e^{-10.5}*(10.5)^{1}}{(1)!} = 0.0003[/tex]
[tex]P(X = 2) = \frac{e^{-10.5}*(10.5)^{2}}{(2)!} = 0.0015[/tex]
[tex]P(X = 3) = \frac{e^{-10.5}*(10.5)^{3}}{(3)!} = 0.0053[/tex]
[tex]P(X = 4) = \frac{e^{-10.5}*(10.5)^{4}}{(4)!} = 0.0139[/tex]
[tex]P(X = 5) = \frac{e^{-10.5}*(10.5)^{5}}{(5)!} = 0.0293[/tex]
[tex]P(X = 6) = \frac{e^{-10.5}*(10.5)^{6}}{(6)!} = 0.0513[/tex]
[tex]P(X \leq 6) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5) + P(X = 6) = 0 + 0.0003 + 0.0015 + 0.0053 + 0.0139 + 0.0293 + 0.0513 = 0.1016[/tex]
10.16% probability that at most 6 trains will pass his house in a 12-hour time period
