Step-by-step explanation:
160 miles = 20 gallons
400 miles = x gallons
160 × x = 20 × 400
x = 8, 000/160
x = 50 gallons
Answer - 150
One square has an area of 25 (5x5) so 6 squares (25x6) have an area of 150.
Answer:
30% Increase
Step-by-step explanation:
we know 3 is 30% of 10 and 10+3=13 so we know that 13 is a 30% increase of 10.
Answer:
B. A water wheel in a dry river
Step-by-step explanation:
Work is said to be done when a force moves a body or an object through a certain distance in the direction of the force. Thus for work to be done, force and distance are required.
i.e Work done = Force x distance
It is measured in Joules.
Also, the work done by an object could be a measured of potential energy.
So that,
Work done = potential energy = mass x gravitational force x height
Considering the collage in the question, since the water wheel is in a dry river no work is done. Water wheel is a device that functions through the flow of water body, thus causing its rotation.
5% total increase, as 3 to 60 is 1/20 (5%)
