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:
0.06 liters
Step-by-step explanation:
acid concentration of 65% means that it of 100 units of that solution 65 are acid, and the remaining 35 are water.
so, 100 units are 0.2 liters in this example.
that means that 65/100 × 0.2 = 0.13 liters are acid.
35/100 × 0.2 = 0.07 liters are water
we get a 50% concentration, when we have the same amount of water and acid in the solution (acid is only half of 50% of the solution).
the account of acid remains the same, as we are only adding water.
so, how much water do we need to get from 0.07 liters to 0.13 liters (the same as the already present acid) ?
0.13 - 0.07 = 0.06 liters

Answer:
38,325 dinners.
Step-by-step explanation:
We have been given that last year the manager of a health care facility served 36,500 dinners. The manager estimates an increase of 5% in the number of dinners to be served next year.
The estimated number of dinners next year would be 36,500 plus 5% of 36,500.
Therefore, 38,325 dinners will be served next year.
