Answer:
750
Step-by-step explanation:
The big showroom has an area of 0.25 million sq. ft.
In the last summer sale, it is surveyed that the population density was 0.003 people per sq. feet and that included all the people in the building.
Therefore, the number of people who attended the summer sale at this showroom on that day was (0.003 × 0.25 × 1000000) = 750. (Answer)
{Since 1 million = 1000000}
Answer:
It will take it 1 and 1/2 hours.
Step-by-step explanation:
Because they walk 5/6 miles in 5/4 hours we can set up a proportion. They walk 1/6 miles in 1/4 hour. Now using the proportion we can find out that they walk 1 full mile or 6/6 of a mile in 6/4 hours or 1 and 1/2 of an hour.
(152÷4)(100÷4) = 3825 when reduced to the simplest form. As the numerator is greater than the denominator, we have an IMPROPER fraction, so we can also express it as a MIXED NUMBER, thus 152100 is also equal to 11325 when expressed as a mixed number.
