Answer:
665.73 cm or 6.65 m
Step-by-step explanation:
The first thing is to pass the distance in meters to centimeters, knowing that 1 meter equals 100 centimeters:
3.6m * 100cm / 1m = 360cm
Now we calculate the number of steps:
360 cm / 18 cm = 20 steps
Now each step measures 28 cm, therefore:
20 * 28 = 560 cm
To calculate the length of the ladder, we must apply Pythagoras:
c ^ 2 = a ^ 2 + b ^ 2
a = 360; b = 560
replacing:
c ^ 2 = 360 ^ 2 + 560 ^ 2
c ^ 2 = 443200
c = 665.73
665.73 cm in meters would be 6.65 meters.
Answer:
There are 10 two point questions and 16 five point questions.
Step-by-step explanation:
- x = the number of 2 points questions
- y = the number of 5 points questions
- x + y = 26
- 2x + 5y = 100
- x = 10 two points questions
- y = 16 five points questions
Answer:
5/36
Explanation:
Distance on a number line is basically difference between two numbers. So we subtract the two numbers. This can be solved on a calculator btw. 7/12 - √16/81 = 5/36.
