Answer:
2.83333
Step-by-step explanation:
The formula is divide the length value of 12
Using th epythagorean theorem.
52^2-48^2= x^2
2704-2304= x^2
400=x^2
x=20
Final answer: D
Answer:
(-8) + (-8) + (-8) + (-8)
Step-by-step explanation:
Since Yan is descending ; we represent his movement as being negative.
Number of rungs descended before stopping = 4
Number of stops = 8
Given that no extra steps was taken ;
Number of ladder rungs descended :
4 rungs per stop for 8 stops
- 4 * 8 = - 32 rungs
Another way to write the product :
Number of stops added in number of rungs descended :
(-8) + (-8) + (-8) + (-8)
