The particle of dust has a mass of 7.53x10 to the-10 kilograms. Find the weight of 5 billion dust particles
To find the weight of 5 billion dust particles, multiply the weight of one particle (determined by the mass of the particle times gravity) by 5 billion. The resulting weight of these dust particles is approximately 36.9 Newtons.
Explanation:The weight of a particle can be determined using the formula weight = mass x gravity. Given that the mass of a dust particle is 7.53x10^-10 kilograms and assuming normal earth gravity which is approximately 9.8 meters per second squared, the weight of one dust particle is about 7.38x10^-9 Newtons. If we want to find the weight of 5 billion such particles, we'd multiply this single particle weight by 5 billion (5x10^9), resulting in a total weight of about 36.9 Newtons.

If 5/8 of the people in water aerobics class are over age 65 and 1/4 of the people in the class are under age 40,what fraction of the people in the class are either over 65 or under 40?
To find the fraction of people in the class who are either over 65 or under 40, we add the fractions of people in each age group. The maximum fraction is 1.
Explanation:To find the fraction of people in the class who are either over 65 or under 40, we need to add the fractions of people in each age group. First, we find the fraction of people over 65 by multiplying the total fraction by the fraction of people over 65: 5/8 * 1 = 5/8. Next, we find the fraction of people under 40 by multiplying the total fraction by the fraction of people under 40: 1/4 * 1 = 1/4. Finally, we add the two fractions together to find the total fraction of people who are either over 65 or under 40: 5/8 + 1/4 = 9/8. However, fractions cannot be greater than 1, so the maximum fraction is 1. Therefore, the fraction of people in the class who are either over 65 or under 40 is 1.

Can someone please solve this:
(a+b)2 - (a-b)2= (they are in square)
note: I know the formula but I don't understand hownu factorize it like why that way, if u want please explain it
(a+b)^2 – (a-b)^2
Since both are squares you end up with
(a+b +a-b) * (a+b –(a-b))
First set of parenthesis add the 2 a’s together to get 2a and subtract b from b
So you end you with 2a
Now you have
2a(a+b –(a-b))
Second set of parenthesis you subtract a from a and then have b+b left which equals 2b
So now you have 2a times 2b
Which equals 4ab
