Thomas decides to use the method of proportions and similar
triangles to find the height of a lamppost. He measures the length of
the post's shadow and finds it is 5 feet long. Then, he holds a 1-foot
ruler perpendicular to the ground and finds that it casts a 2-inch
shadow. How tall is the lamppost?
a. 2.5 ft c. 30 ft
b. 12 ft d. 60 ft
Answers
Answer:
The lamppost is 30 ft tall.
Step-by-step explanation:
You need to draw a diagram of the problem. Refer to attachment.
Now you need to convert the measurements that are in feet to in. The 1 foot ruler is now 12 in. and the 5 foot post's shadow is now 60 in.
The next step is to create a proportion between both angles. [tex]\frac{x}{1} =\frac{60}{2}[/tex]
x over 1 is simplified to x and 60 divided by 2 is just 30. So the lamppost is 30 ft tall.
Hope that helped. :)

3(4x - 8) = 15x - 10 - 3x. Explain if this is an infinite, one or none solution problem. Explain your answer!!
Answers
Answer:
There are no solutions to this answer.
Step-by-step explanation:
I checked my answer by going to an app and they said there was no answer to the question too.
Because when you do the equation:
3(4x - 8) = 15x - 10 - 3x
12x - 24 = 12x - 10 (First=Distributes)
+10 = 12x + 10 (Move the# & add)
——————————
12x - 14 = 12x (Move the coefficient)
-12x = -12x (Subtract both side)
———————
0x - 14 = 0x
So there is no solution to this problem!

A-65.2
B-192
C-39
D-13.2
Answers
Answer: it's c
Step-by-step explanation:The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.
56+21+55+30+33/5=39
Answer: i think the answer is 39
Step-by-step explanation: the mean is the average of all the numbers so you would add 56+21+55+30+33 =195 you would then dived the total by the amount of numbers there are in this situation there are 5 so you would do 195diveded by 5 which = 39 I hope this makes since and this helps if this is not what your asking plz clarify :)
The length of a path from a picnic area to the playground is 34 mile. The path has signs with arrows pointing to the playground every 18 mile.
How many signs are placed along the path, assuming that there is a sign at the beginning of the path but not at the end?
Answers
An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
The number of signs that are placed along the path, assuming that there is a sign at the beginning of the path but not at the end is 2 signs.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Length of the path = 34 mile
There is a sign after every 18 miles.
Now,
There is a sign at the beginning of the path and not at the end.
The number of signs:
= 34 ÷ 18
= 34/18
= 1.8
This means there will be one sign.
Now,
There was a sign at the beginning so we have,
1 + 1 = 2 signs
Thus,
The number of signs that are placed along the path, assuming that there is a sign at the beginning of the path but not at the end is 2 signs.

The event coordinator asks you to determine how many students participated in the
track-and-field day. The total number of students in seventh and eighth grade
combined is 584; 5/8 of them are seventh graders and 3/8 of them are eighth-graders. If 4/8 of the seventh graders participated in track-and-field day and 7/8 of the eighth graders participated, about how many total students participated? Describe the process you used to find your answer.
Answers
Answer:
374.125 students. Not sure if you're supposed to round up or down considering you can't have a fraction of a person, but I would round down.
Step-by-step explanation:
(5/8) (584) = 365 seventh graders in total
(3/8) (584) = 219 eighth graders in total
(4/8) (365) = 182.5 seventh graders who participated in track-and-field day
(7/8) (219) = 191.625 eighth graders who participated in track-and-field day
182.5 + 191.625 = 374.125 students in total who participated
Answer:
First, I took 5/8 out of 584 for the seventh graders which came out to 365 seventh graders. Then, I did the same thing with 3/8 and it came out to 219 eighth graders. Then I took out 4/5 out of 365 which resulted as 292. Then I did the same thing for 7/8 and the results came out as 191. So in total 483 students participated in track-and-field day.

Claire is on a business trip. She’ll be traveling from Liverpool, England, to Melbourne, Australia.
The latitude value of Liverpool is 53.41 degrees, and the longitude value is -2.99 degrees. The latitude value of Melbourne is -37.81 degrees, and the longitude value is 144.96 degrees. The two cities are
degrees apart in latitude. The two cities are
degrees apart in longitude.
Answers
Answer:
the difference in latitude is 91.22°
the difference in longitude is 147.95°
Step-by-step explanation:
For Liverpool, London. The latitude is 53.41°, longitude is -2.99°
For Melbourne, Australia. The latitude is -37.81°, longitude is 144.96°
The negative or positive magnitude of their values shows their position on either sides of the origin of the latitude (equator) and the origin of the longitude (prime meridian).
The latitude measures the relative position of a point, north or south of the equator (latitude 0°). The longitude measures the relative position, east or west of the prime meridian (longitude 0°)
the difference in latitude is 53.41° - (-37.81°) = 53.41° + 37.81° = 91.22°
the difference in longitude = 144.96° - (-2.99°) = 144.96 + 2.99 = 147.95°
