Answer:
10 seconds.
Step-by-step explanation:
The velocity at which they are approaching each other = 59 + 41 = 1000 km per second.
Velocity = distance / time
So time = distance / velocity
= 1000 / 100
= 10 seconds.
Answer:
25
Step-by-step explanation:
3877 divided by 36 is 107.69. That means each person could get 107 masks (always round down in these problems)
36 time 107 is 3852, and 3877 minus 3852 is 25. This is how many will be left over.

Answer:
a. 90º
Explanation:
The chords ST and RA intesect at Y, so that SY is now perpendicular to RY and they form an angle 90 degrees at that point. However angles mSA and mRT are both at the circumference of the circle(a chord is a line from point of a circle's circumference to the other) and are both 90 degrees because angle at the circumference is half of angle at the centre in same arc.
