The National Safe Kids Campaign and Bell Sports sponsored a study that surveyed 8,159 children ages 5 to 14 who were riding bicycles. Approximately 2/5 of the children were wearing helmets, and of those, only 13/20 were wearing the helmets correctly. About how many of the children were wearing helmets correctly?
Final answer:
To find the number of children wearing helmets correctly, multiply 2/5 by 8,159 to get the number of children wearing helmets, then multiply that result by 13/20 to get the number of children wearing helmets correctly, which is approximately 2,134.
Explanation:
The student's question involves mathematical computations to determine how many children were wearing helmets correctly out of a surveyed group. The data provided indicates that 2/5 of the 8,159 children were wearing helmets, and out of those, 13/20 were wearing the helmets correctly. To calculate the exact number of children wearing helmets correctly, we should perform the following steps:
Calculate the number of children wearing helmets: (2/5) × 8,159 = 3,263.6, which we can round down to 3,263 children, since we cannot have a fraction of a child.
Calculate the number of children wearing helmets correctly: (13/20) × 3,263 = 2,134.95, which we can round down to 2,134 children wearing helmets correctly.
Therefore, approximately 2,134 children were wearing helmets correctly.

What is 540 divided by 36 using partial quotients
Write a division problem that has a 3-digit dividend and a divisor between 10 and 20. Show how to solve it by drawing a quick picture.
Answer:
In the division problem,
The number which is divided is called dividend,
While, the number which divides, is called divisor,
Let dividend = 150 ( a three digit number ),
Divisor = 15 ( a number between 10 and 12 ),
So, the problem would be,
[tex]150\div 15[/tex]
In the below figure,
Take a grid that shows 150,
Divide this grid such that each box represents 15,
Thus, there are such 10 boxes,
That is,
[tex]150\div 15 = 10[/tex]
Rory is staying in a cabin on a hill 300 feet above sea level. She walks down the hill to the water’s edge. The equation of her average change in elevation over time is e = 300 – 10t, where t is the time in minutes since she left the cabin, and e is her elevation with regard to sea level. Which values are viable points, and what are their values in the table relating t and e?
Rory's change in elevation over time is described by the equation e = 300 - 10t. Viable points are (0, 300), (10, 200), (20, 100), and (30, 0) feet, indicating that she reaches sea level after 30 minutes.
Understanding Rory's Change in Elevation:
Rory is walking down a hill from a cabin that is 300 feet above sea level. The equation describing her elevation over time is given by e = 300 - 10t, where e represents elevation regarding sea level, and t is the time in minutes since she started her journey.
Calculating Elevation Points:
To determine the viable points, we'll plug in different values of t into the equation to get corresponding values of e:
When t = 0,
e = 300 - 10(0) = 300 feet
When t = 10,
e = 300 - 10(10) = 200 feet
When t = 20,
e = 300 - 10(20) = 100 feet
When t = 30,
e = 300 - 10(30) = 0 feet
These values suggest that at t = 30 minutes, Rory reaches sea level.
Creating a Table:
The viable points and their corresponding values of e can be summarized in the following table:
(t = 0, e = 300 feet)
(t = 10, e = 200 feet)
(t = 20, e = 100 feet)
(t = 30, e = 0 feet)

4. Describe the number set(s) the number belongs to: −√17
The number -√17 is an irrational number and is part of the set of real numbers.
Explanation:The number -√17 belongs to the set of real numbers. However, because this number is the square root of a positive number (17) and is multiplied by negative sign, it is not a rational number, but rather an irrational number.
It is part of the real numbers because the set of real numbers includes all numbers that can be plotted on a number line, including integers, rational numbers (numbers that can be expressed as a quotient of two integers), and irrational numbers (numbers that cannot be expressed as a quotient of two integers).
It is specifically an irrational number because the square root of 17 is a non-repeating, non-terminating decimal, and when we multiply this by a negative sign, the numerical value itself does not change, only its direction on the number line.

Step-by-step explanation:
125 students have volunteered to be on the prom committee. 2 of those students will be randomly chosen to win free tickets to the prom. How many different ways can the winners be chosen?
Final answer:
There are 7,750 different ways the two winners can be chosen from the 125 students volunteering for the prom committee, calculated using the combination formula C(n, k) = n! / (k!(n-k)!).
Explanation:
To determine how many different ways the two winners can be chosen from the 125 students, we need to use the concept of combinations, because the order in which we choose the winners doesn't matter. The formula for combinations is given by:
C(n, k) = n! / (k!(n-k)!)
where:
n represents the total number of items,
k represents the number of items to choose.
For this situation:
n = 125 (total students),
k = 2 (winners to choose).
Therefore,
C(125, 2) = 125! / (2!(125-2)!)
= 125! / (2! * 123!)
= 125 * 124 / (2 * 1)
= 7750
So, there are 7,750 different ways the winners can be chosen to win free tickets to the prom.
Which simplified fraction is equal to 0.17 (7 repeating)
Answer:
[tex]\frac{8}{45}[/tex]
Step-by-step explanation:
We are given that
[tex]0.1\bar 7[/tex]
We have to find the value in fraction of given rational number
Let x=[tex]0.1\bar 7[/tex]
Multiply on both side by 10 then we get
[tex]10 x=1.77...[/tex]
[tex]10x=1.6+0.1\bar 7[/tex]
Substitute the value then we get
[tex]10x=1.6+x[/tex]
[tex]10x-x=1.6[/tex]
[tex]9x=1.6[/tex]
[tex]x=\frac{1.6}{9}[/tex]
[tex]x=\frac{16}{90}[/tex]
[tex]x=\frac{8}{45}[/tex]
Hence, the fraction =[tex]\frac{8}{45}[/tex]
Express 4 8\9 as an improper fraction
The improper fraction of the given expression is [tex]\frac{44}{9}[/tex].
What is the improper fraction?A fraction with a numerator greater than or equal to the denominator is said to be improper. The denominator is the lower number, and the numerator is the top number. When you have wholeness or more than one whole, you can have improper fractions. Here are a few instances of incorrect fractions:
7/5 18/18 100/13
We can see the number of pieces we have in the numerator and the number of parts we are dividing by in the denominator. In the case of an improper fraction, like the first one mentioned above, there are seven parts, each of which is a fifth of the whole.
The improper fraction of [tex]4 \frac{8}{9}[/tex] [tex]=[/tex] [tex]\frac{(9*4)+8}{9}[/tex]
[tex]=[/tex] [tex]\frac{36+8}{9}[/tex]
[tex]=[/tex] [tex]\frac{44}{9}[/tex]
