Answer:
SB or ? = 9
Step-by-step explanation:
Since the two triangles are similar.
((18 + 6) / 6) = 24 / 6 = <u>4</u>
[Scale factor between ∆BCU and ∆SUT]
SB or ? = 12 – 12/<u>4</u> = 12 – 3 = 9
Answer:
Step-by-step explanation:
33×10^-3 is equivalent to 33/1000, or 0.033.
This, in turn, is equivalent to 3.3×10^(-2) (which is in scientific notation)
Answer:
17. 10
Step-by-step explanation:
1. A segment going from an endpoint to the midpoint of the original segment is going to be 1/2 of the original segment.
AM = 1/2 AB
2. You know that the length of AM is 5, so plug that in a solve algebraically
5 = 1/2 AB
(2)5 = (2) 1/2 AB
10 = AB
Answer:
18. 30
Step-by-step explanation:
The sum of two segments spanning from the original segment's midpoint to the end equals the length of the original segment. Because the midpoint is exactly in the middle of the original segment, the two other segments should equal each other.
1. You need to first find the length of the two segments by setting them equal to each other and plugging in their equations.
5x = x+12
2. Solve algebraically
5x = x+12
4x = 12
x = 3
3. Plug z into the equations for each segment and add them together.
RM = 5(3) MS = (3)+12
RM = 15 MS = 15
15+15 = 30
To find the area of the arena, you will need to find the areas of the rectangular spaces and the 2 semicircles. Because the formulas are given, I will just substitute in the values and show the work for finding the areas.
To find the perimeter, you will look at the distances of lines that take you around the space. Because two of these spaces are half circles, you will need to find the circumference of the full circle.
Also, the answers need to be given in meters, so all units given in centimeters will be divided by 100 to convert them to meters.
Perimeter:
C= 3.14 x 20 m
C = 62.8 meters
62.8 + 8 + 25 + 8 + 5 + 8 + 10 + 8 + 40= 174.8 meters for the Perimeter
Area:
A = 25 x 8
A = 200 square meters
A = 10 x 8
A = 80 square meters
A = 20 x 40
A = 800 square meters
A = 3.14 x 10^2
A = 314 square meters
Total Area: 314 + 800 + 80 + 200= 1394 square meters
Answer:
10
