I think it is 25% but you need to work out ;)

<span>Speed
is calculated as distance covered, divided by the time taken to cover that
distance. In this case, the sales person covered 50KM in 45minutes (which can
also be expressed as 3/4 hours). To calculate the speed he used to cover this
distance, we divide the distance covered by the time taken. So 50km/3/4hours.
This gives us 66.67km/hr. In order to calculate the amount of time the
salesperson used to travel from the office to the sales person, we calculate
as follows 250km/66.67km/hr. This gives us a total of 3.75 hours or 3 hours 45 minutes.</span></span>
All of them.
1. If you multiply by 2, they will be equal.
2. If you multiply by 5000 they will be equal.
3. If you divide by 3 they will be equal.
Answer:
a) 
b) 
c) 
d) 
Step-by-step explanation:
We know that the circle is increasing its radio from an initial state of r=0 cm, at a rate of 5 cm/s.
This can be expressed as:
a) Radius of the circle, r (in cm), in terms of the number of seconds, t since the circle started growing:
b) Area of the circle, A (in square cm), in terms of the circle's radius, r (in cm):
c) Circle's area, A (in square cm), in terms of the number of seconds, t, since the circle started growing:
d) Expanded form for the area A:
Answer:
i think 9+(-4) and 9-4.
