To find the greatest number of children that will receive a set of items on opening day, we can find the greatest common divisor of the quantities of ball caps, keychains, and bracelets.
Explanation:To find the greatest number of children that will receive a set of items, we need to determine the number of identical sets that can be made from the available items. We can do this by finding the greatest common divisor (GCD) of the quantities of ball caps, keychains, and bracelets.
The GCD of 120, 180, and 240 is 60. This means that 60 sets of items can be made, with each set consisting of 2 ball caps, 3 miniature baseball keychains, and 4 glow-in-the-dark bracelets.
Therefore, the greatest number of children that will receive a set of items on opening day is 60.

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.

On morgans 3rd birthday, she weighed 45 pounds. On her 12th birthday, she weighed 105 pounds.Find the rate of change in her weight.
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
It takes Francisco 15 minutes to ride his bike 4 km, which is the distance from home to school. What is his average speed?
Answer:
The average speed is 16 km/hr.
Step-by-step explanation:
Given : It takes Francisco 15 minutes to ride his bike 4 km, which is the distance from home to school.
To find : What is his average speed?
Solution :
Distance covered from home to school is 4 km.
Time taken by bike to cover the distance is 15 minutes.
Converting minutes into hour,
1 hour = 60 minutes
1 minute = [tex]\frac{1}{60}[/tex] hours
15 minute = [tex]\frac{15}{60}[/tex] hours
15 minute = 0.25 hours
The speed formula is given by,
[tex]\text{Speed}=\frac{\text{Distance}}{\text{Time}}[/tex]
[tex]\text{Speed}=\frac{4}{0.25}[/tex]
[tex]\text{Speed}=16[/tex]
Therefore, The average speed is 16 km/hr.

steve is 5 years older than his brother joe. in 4 years steve will be twice as old as joe will be then. how old is steve now?
The question requires the use of algebraic expressions to determine the ages of Steve and Joe. Solving the appropriate equation yields that Steve is 6 years old.
Explanation:
This problem can be solved using basic algebraic expressions. If we assume the current age of Joe to be 'x' years, then Steve, being 5 years older, is 'x + 5' years old. Now, in 4 years, Joe's age will be 'x + 4' and Steve's age will be '(x + 5) + 4' which equals 'x + 9'. According to the question, Steve will be twice as old as Joe in 4 years, so we can express this relation algebraically as '2(x + 4) = x + 9'. Solving this equation yields 'x = 1', which means that Joe is currently 1 year old, and thus, Steve is currently 1 + 5 = 6 years old.
