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}
If I am correct the answer is 1.
You can do multiply 3 by 6/8 which will give you 2 1/4 or if in a decimal 2.25.
Then do 3 by -1/2 which will give you -1 1/2 and in decimal its -1.5.
You continue with the equation, 2.25 -1.5 = 0.75 + 0.25 = 1
Add them all together and you get 1...!
Hope this Helps :)
Answer:
40%
Step-by-step explanation:
Percent means out of 100
Multiply the top and bottom by 20 to get the bottom to 100
2/5 * 20/20 = 40/100
The percent is 40%
A perfect square is a number that can be expressed as the product of two equal integers. To determine that a trinomial is a perfect square we use the the discriminant given by:
b^2-4ac
where a,b and c have been obtained from the trinomial given by:
ax^2+bx+c;
if the value of the discriminant is a perfect square then the trinomial is a perfect square trinomial
