First of all, assuming that the "ground level" is 0;
The lift is not starting from 0, so we also need to account for the extra 15 meters above the ground the lift is.
The total distance the lift would cover in the downward direction: 15+350=365m
Now, you know that the lift covers 5 m/min
Therefore, 5x=365 (ignoring units because they can complicate things)
x=365/5
x=73 minutes
Therefore, they would take 73 minutes to reach 350 m deep into the ground with a starting position 15 m above the ground.
Hope I helped :)
Use slope formula to find slope
<span><span><span>−9−5</span><span>−/12−8</span></span>=<span><span>−14/</span><span>−20</span></span>=<span>7/10</span></span>
7/10 = m = slope
y= mx + b
y= (7/10)x + b
(8,5)
(5) = (7/10)(8) + b
b = -3/5
So....
<span>y=(<span>7/10)</span>x −<span>35
</span></span>
multiply by 10
<span>10y=7x−6</span><span>
--> -7x + 10y = -6
--> 7x - 10y = 6
So, if 7x - 10y = 3 a good model?</span>
As in each table can seat 8 people and the probability you need to find is about the first person you can ignore this data.
Probability that the first person to enter the room will be randomly seated at a maple table:
#maple tables: 9
# total tables: 9 +10 +5 +7=31
Then, the probability that the first person to enter the room will be randomly seated at a maple table is 9/31
40%less
You take 36/60
That equals 60%
This means that 36 is 60% of 60
So in 24 is 40% of 60 or 36 is 40% less than 60
