Answer:
option A. 21 sec
Step-by-step explanation:
Speed = the distance over the time
Given:
Speed = 2 m/s and distance = 42 m and time = t
So,
2 = 42/t
Solve for t
t = 42/2 = 21 sec.
The answer is option A. 21 sec
Answer:
36.1 meters
Step-by-step explanation:
Since this is a rectangle, the parallel sides are equal to each other, meaning we technically already know all the side lengths.
I'll choose to look at the bottom triangle in this case
30 is already there, and the other leg should be 20. Knowing this, we can plug these into the pythagorean theorem.
20 is A, 30 is B, and the missing side is C

C, the missing side to the nearest tenth is 36.1 meters
Answer:
I think it is 100000 0 value is more than ever number
Answer:
Step-by-step explanation:
so llets find what 15% of 60% really is,
0.15*0.60=0.09
0.09 AKA 9%
so since 9% of people didn't show up we can subtract 9% from 60%
so 60-9=51
51% of setas are taken
to find the percent of seats still empty, subtract 100 form 51
so
100-51=49
49% of seats are still empty
Hope this helsp!
