Answer:
153 ways.
Step-by-step explanation:
The answer is the number of combinations of 2 from 18
= 18! / 2! (18-2)!
= 18! / 2! 16!
= 18*17*16! / 2! 16!
= 18 * 17 / 2*1
= 9 * 17
= 153 ways.
Answer:
The slopes are neither perpendicular nor parallel.
Step-by-step explanation:
First we are going to find the slope-inercept form from the equation, -2x + 10y = 5.
Solve for y.
-2x + 10y = 5
<u>+2x. =</u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u>+2x</u>
10y = 2x + 5

So we now have

Looking at the equation above, the slopes are neither perpendicular nor parallel.
Answer:
10/16; 15/24; etc
Step-by-step explanation:
if u multiply any fraction, both parts of it by the same number, ull get an equal expression. so, for example, 5*2/8*2=10/16=5/8
40% is close to 50% which is = to 1/2
So just divide 60 by 2. which would be around 30
this is the best way i could explain, I hope this helps
Given that a<span> passenger elevator in the sears tower in Chicago can lift people 960 feet in 1 minute and 30 seconds (1.5 minutes). This means that the lift is travelling with a speed of:
