<h3>Units conversion</h3>

Unit conversion is a way of converting some common units into another without changing their real value. for, example, 1 centimetre is equal to 10 mm, though the real measurement is still the same the units and numerical values have been changed.

Given water flows from a shower at a rate of 0.35 cubic feet per minute. Therefore, the water that will be used in the shower,

Water used in Shower = 0.35 × 15 = 5.25 cubic feets

Water used in bathtub = 0.5 yards³ = 13.5 cubic feets

Hence, the option in which more water will be used is by filling a bathtub.

a factory could produce 84 toy robots in one day. They purchased some new equipment. Now they can produce 105 robots in one day.
kompoz [17]

Answer:

The answer to the question is

25 % increase in production rate

Step-by-step explanation:

To solve the question, we note that

Initial number of products = 84 toy robots per day

Present production rate = 105 robots per day

The percentage increase is given by the increase in production rate divided by the original production rate multiplied by 100  

Where increase in production rate = 105 - 84 = 21

Percentage increase = 21/84 ×100 = 25 % increase
