Answer:
Step-by-step explanation:
10 cm represents 5 meters in the real world
6 cm represents x meters
cross multiply
10x = 5*6
10x = 30
x = 3 meters so 6cm is equal to 3 meters in length
10 cm represents 5 meters in the real world.
5 cm = y meters
10y = 5*5
10y = 25 m
y = 25/10 meters = 2.5 meters
Area of the room = 2.5 * 3 = 7.5 square meters
Answer: C
Step-by-step explanation:
The area of a circle is ∏r2- (Pi)(Radius)-squared
The Answer is C
Answer:
False, I think
Step-by-step explanation:
I’m not getting the full question but 4 cannot equal 23 so I would say false
Answer:
B. 6
Step-by-step explanation:
A is between P and R
- PA + AR = PR
- 3x - 4 + 7 = 21
- 3x + 3 = 21
- 3x = 18
- x = 6 m
Correct option is B. 6
Answer/Step-by-step explanation:
1. x*21 = 24*14 (intersecting chords theorem)
21x = 336
x = 336/21
x = 16
2. 27*x = 45² (secant-tangent rule)
27x = 2,025
x = 2,025/27
x = 75
3. (x + 5)*5 = (4 + 6)*6 (Intersecting secants theorem)
5x + 25 = (10)*6
5x + 25 = 60
5x = 60 - 25
5x = 35
x = 35/5
x = 7
4. (4x + 2)*8 = (5x + 1)*7
32x + 16 = 35x + 7
Collect like terms
32x - 35x = -16 + 7
-3x = -9
x = -9/-3
x = 3
