Kyle sprinted for 1/4 mile. Ron sprinted the same distance. Which of the following represent the distance Ron sprinted?
Answers
If Ron sprinted the same distance, Ron sprinted for 1/4 mile. To find the values that are the same as 1/4, let's simplify the fractions.
To simplify the fractions, divide the numerator and the denominator by an integer. The result of each division must be an integer too.
(a) 2/4
Divide both the numerator and the denominator by 2.
[tex]\frac{\frac{2}{2}}{\frac{4}{2}}=\frac{1}{2}[/tex]1/2 ≠ 1/4.
(b) 3/4
This fraction can not be simplifyed.
3/4 ≠ 1/4.
(c) 2/8
Divide both the numerator and the denominator by 2.
[tex]\frac{\frac{2}{2}}{\frac{8}{2}}=\frac{1}{4}[/tex]2/8 = 1/4.
(d) 3/12
Divide both the numerator and the denominator by 3.
[tex]\frac{\frac{3}{3}}{\frac{12}{3}}=\frac{1}{4}[/tex]3/12 = 1/4.
(e) 7/8
7/8 can not be simplied.
Answer:
2/8 and 3/12.

Answers
Let's picture the situation described by the exercise:
We have a circle with radius r, and a (green) sector with an area of 361.6 m^2, and with a central angle of 288 degrees. To solve this exercise, we merely need to remember the formula for the area (AS) of a sector:
[tex]AS=\frac{\text{angle}}{360}\cdot\pi\cdot r^2.[/tex]For we are looking for the radius, we need to solve this "equation" for the variable r:
[tex]\begin{gathered} AS=\frac{\text{angle}}{360}\cdot\pi\cdot r^2, \\ 360\cdot AS=(\text{angle)}\cdot\pi\cdot r^2, \\ \frac{360\cdot AS}{(\text{angle)}\cdot\pi}=r^2, \\ r^2=\frac{360\cdot AS}{(\text{angle)}\cdot\pi}, \\ r=\sqrt[]{\frac{360\cdot AS}{(\text{angle)}\cdot\pi}}\text{.} \end{gathered}[/tex]Evaluating for the values of AS and "angle" of our sector, we get
[tex]\begin{gathered} r=\sqrt[]{\frac{360\cdot AS}{(\text{angle)}\cdot\pi}}\leftarrow\begin{cases}AS=361.6m^2 \\ angle=288 \\ \pi=3.14\end{cases}, \\ r=\sqrt[]{\frac{360\cdot361.6m^2}{288\cdot(3.14)}}, \\ r\approx\sqrt[]{143.9m^2}, \\ r\approx11.9m. \end{gathered}[/tex]Finally, we must round up the value of r we just obtained. Note that the first decimal place (9) of 11.9 is greater than 5, then by the rounding rule we must add one tenth, to get

Given the word problem, we can deduce the following information:

P=Perimeter =144 cm
l=length
w=width =39 cm
We plug in what we know:

Use technology to find points and then graph the line y=-5(x-5)+1, following the instructions below.
Answers
According to the given question, we are to plot the graph of the line y= -5(x-5)+1. To do that, we will first create coordinate points on the plane in the form of (x, y)
If y = 10, then;
10 = -5(x-5) + 1
10-1 = -5(x-5)
9 = -5(x - 5)
x- 5 = -9/5
x - 5 = -1.8
x = -1.8 + 5
x = 3.2
Hence one of the coordinates that fit is ABB(3.2, 10)
If y = 5, then;
5 = -5(x-5) + 1
5 - 1 = -5(x - 5)
4 = -5(x - 5)
x - 5 = -4/5
x - 5 = -0.8
x = -0.8 + 5
x = 4.2
Another coordinate point that fit into the plane is B(4.2, 5)

We will investigate how to express percentages as decimals ( fractions ). Then we will see how to manipulate these percentages to get the starting or resltant value.
We are asked to determine the " starting number " whose 0.2% would result in the final number:
[tex]22[/tex]We will first see how to deal with the percentage ( 0.2% ) and the starting number which is an unknown. So lets suppose:
[tex]\text{Starting number = x}[/tex]Then we will see how to deal with percentages. The way we deal is by using a basic mathematical operator of ( multiplication ) and convert the percentage into a fraction as follows:
[tex]\begin{gathered} \text{Starting number }\cdot\text{ Percentage} \\ x\cdot\frac{0.2}{100} \end{gathered}[/tex]Then we will equate the above expression to the resultant as follows:
[tex]x\cdot\frac{0.2}{100}\text{ = 22}[/tex]Now we have aa full fledged equation. We can easily manipulate and solve for the unknown number ( x ) as follows:
[tex]\begin{gathered} x\cdot0.2\text{ = 2200} \\ x\text{ = }\frac{2200}{0.2} \\ \textcolor{#FF7968}{x}\text{\textcolor{#FF7968}{ = 11,000}} \end{gathered}[/tex]We see the unknown starting number ( x ) is very large as should have been the case. This is due to the fact that ( 0.2% ) is a very small proportion of a number such that it results in a two-digit number like ( 22 ). If the percentage is low but resultant is high, then the starting number must be very large!

The cost of 2 pencils and 3 notebooks is 3.35
2p + 3n = 3.35
The cost of 4 pencils and 2 notebooks is 3.70
4p + 2n = 3.70

4p + 2n = 3.70
Multiply the first equation by 2 and the second equation by 1

what is the difference in the length between the shortest
Answers
1) Considering the group of the longest worms size is 1 and 1/2 inch and the shortest ones have the size of 3/4 of an inch.
2) Firstly, let's convert the mixed number to an improper fraction and then subtract.
[tex]1\frac{1}{2}=\frac{(2\cdot1+1)}{2}=\frac{3}{2}[/tex]We do this by conserving the denominator and multiplying it by the whole number and adding to the numerator:
To find the Least Common Multiple (LCM), we proceed this way:
We divide those numbers for a prime number, that divide both (2 and 4) and go on until we reach 1. Then we multiply the numbers on the right. ( 2 and 2)
3) Now let's subtract then. Since they have different denominators, then we must calculate the Least Common Multiple of both:
[tex]\begin{gathered} \frac{3}{2}-\frac{3}{4} \\ \frac{(4\colon2\times3)-(4\colon4\times3)}{4}= \\ \frac{6-3}{4}= \\ \frac{3}{4} \end{gathered}[/tex]The LCM between 2,4 is 8. So the difference between the longest size (3/2 inches or 1 1/2 ) and the shortest 3/4 is equal to 3/4
