Answer:
2 scoops per pitcher,
Step-by-step explanation:
2 (per pitcher) * 4(pitchers) = 8
2 scoops makes 1 pitcher and she's using 8 scoops so that would give us 4 pitchers.
Answer:
the average speed of the whole journey is 45 km/h
Step-by-step explanation:
The computation of the average speed of the whole journey is shown below:
Average speed is
= (Speed 1 + speed 2) ÷ 2
= (60 km/h + 30 km/h) ÷ 2
= 90 km/h ÷ 2
= 45 km/h
Hence, the average speed of the whole journey is 45 km/h
We simply ignored the distance as it is not relevant for the given situation

The coordinates of the car right now is (8,9)
So, imagine the trainer is in the very middle of the circle and he is holding out a rope that's attached to the horse. The rope here from the trainer to the horse represents the radius of the circle. The horse trots around the trainer (middle point) in a circle.
The formula to find area of a circle is A = pi*r^2 (pi times r squared where r is radius)
We know that the radius of the "circle" here formed as the horse trots around the trainer is 31 (the 31 foot long rope).
So let r = 31 & plug the value into the formula to find circle area.
A = pi*31^2 = 3019.07054
The area is therefore 3019.07 square feet. (rounded)
