This year the winner of the New York Marathon ran the 8-kilometer event in 24 minutes. What is the runner’s unit rate?
8km - 24 minutes, to find the unit rate (how long it took to run 1km)
We would make a ratio,
8:24
Now just simplify,
8:24
=
1:3
Therefore the unit rate would be 1 kilometer covered for every 3 minutes.
Answer:
0.33 repeating kilometers per minute. 1km/3min

Answer:
[tex] y = -\dfrac{4}{5}x + 11 [/tex]
Step-by-step explanation:
(5, 7), (10, 3)
[tex] m = \dfrac{y_2 - y_1}{x_2 - x_1} = \dfrac{3 - 7}{10 - 5} = -\dfrac{4}{5} [/tex]
[tex] y = mx + b [/tex]
[tex] y = -\dfrac{4}{5}x + b [/tex]
[tex] 7 = -\dfrac{4}{5} \times 5 + b [/tex]
[tex] 7 = -4 + b [/tex]
[tex] b = 11 [/tex]
Answer:
[tex] y = -\dfrac{4}{5}x + 11 [/tex]
Mark is planning to apply to a college in Indianapolis. The breakdown of the cost per year of college is given below.
• Housing Fee: $5,600 (annual cost)
• Tuition Fee: $2,600 per semester
• Technology Fee: $150 per semester
• Books: $310 per semester
• Plane Ticket Cost: $289 (annual cost)
Mark's total cost for s semesters of school in 4 years is represented by the expression below.
$23,556 + $3,060
Which statement best describes the constant in the expression?
It is the total cost for one semester for tuition and plane tickets.
It is the total cost for tuition, technology, and books for four years.
It is the total cost for tuition, technology, and books per semester.
It is the total cost of housing and plane tickets for four years.
Answer:
It is the total cost of housing and plane tickets for four years.
Step-by-step explanation:
Mark's costs for tuition, technology fee, and books are all per semester, s. ($2,600 + $150 + $310)s = $,060s
The cost for housing and plane tickets are a once a year cost. Mark pays these amounts once a year for four years.4($5,600 + $289) = $23,556
Therefore, the constant in the expression is $23,556, and it is the total cost for housing and plane tickets for four years.
Put these numbers in ascending order, smallest first.

In 2015, approximately 734.1 million tons of wheat were produced globally. China produced the most wheat of any country, at 130.2 million tons. What percentage of the world's wheat yield did China produce in 2015? Round your answer to the nearest whole number.
Answer:
China produced 18% of the world's wheat yield in 2015.
Step-by-step explanation:
To determine the percentage of the world's wheat yield China produced in 2015, we will divide the quantity of wheat China produced by the total quantity of wheat produced globally and then multiply by 100%.
From the question,
Wheat produced globally in 2015 = 734.1 million tons
Wheat produced by China in 2015 = 130.2 million tons
Percentage of the world's wheat yield China produced in 2015 =
(130.2 million tons / 734.1 million tons) × 100%
= 0.17736 × 100%
= 17.736%
= 18% ( to the nearest whole number)
Hence, China produced 18% of the world's wheat yield in 2015.
Which of the following lines is perpendicular to the line y = -3 x + 2 and passes through the point (–2, 8)?
Answer:
y = 1/3x + 26/3
Step-by-step explanation:
Original equation: y = -3x + 2
Perpendicular lines have the "opposite reciprocal" slopes of each other, meaning you flip the numbers and reverse the sign.
Slope of original equation: -3
Slope of perpendicular line: 1/3
How: Reciprocal, flip the numbers: -3/1 to -1/3, then reverse sign -1/3 to 1/3
Then you substitute (-2, 8) into the new equation: y = 1/3x + b
*there's b because you don't know the y-intercept yet
Substitute: 8 = 1/3(-2) + b
8 = -2/3 + b
Add 2/3 on both sides
b = 24/3 + 2/3
b = 26/3
*this is the y-intercept
Therefore, the perpendicular equation is: y = 1/3x + 26/3

21. For Dish it costs $40 each month for cable and $3.50 for every movie
you rent. For Direct TV it cost $75 each month for cable and $2,25 for every
movie you rent. Write and solve an equation to find the number of movies
you need to purchase for the cost to be the same each month. [No need
for a label.) •
Your a Tswer
This is required Question
Answer:
You would have to rent 28 movies.
Step-by-step explanation:
You would set up the problem as a system of equations. This means that you have to have two equations.
Dish: [tex]y=3.50x+40[/tex]
Direct TV: [tex]y=2.25x+75[/tex]
In order to find the answer to these, you can either graph them or set them equal to each other. If you graph them, the answer is where the two lines intersect. For this, we will set them equal to each other:
[tex]3.50x+40=2.25x+75[/tex]
To start, since there is a number with the same variable on both sides, we must subtract the lower one from both sides of the equation. In this case, we will subtract [tex]2.25x[/tex] from both sides, giving us:
[tex]1.25x+40=75[/tex]
Now, we solve like a normal two-step equation.
Subtract 40 from both sides:
[tex]1.25x=35[/tex]
After that, we will divide both sides of the equation by 1.25:
[tex]\frac{1.25x}{1.25}=\frac{35}{1.25}[/tex]
This gives us:
[tex]x=28[/tex]
Which means you would have to rent 28 movies exactly in order for their prices to match.
Please helpppp what is the solution to this: 8 < 3x - 1 < 17
Answer:
3 < x < 6
Step-by-step explanation:
8 < 3x - 1 < 17
Add 1 to all sides
8+1 < 3x - 1+1 < 17+1
9 < 3x < 18
Divide all sides by 3
9/3 < 3x/3 < 18/3
3 < x < 6
Answer:
x=(3,6)
Step-by-step explanation:
3x-1>8 and 3x-1<17
3x>9 3x<18

How do I find the percentile of someone with a certain number of things from a dot plot data set?
Answer:
percentile rank of x =
number of values before x 100
--------------------------------------------------- x ----------
number of total values on the dot plot 1
Step-by-step explanation:
you divide the number of values before x over the number of total values on the dot plot, and divide the quotient by 100 to get your percentile.
36. A group of 30 students from the senior class
charters a bus to an amusement park. The total
amount they spend on the bus and admission
to the park for each student is $1,770.
A group of 50 students from the junior class
also go to the amusement park, but they
require two buses. If the group from the junior
class spent $3,190 in total, how much does it
cost to charter one bus?
LESSON 4-3 Solving Systems of
I got $720 because i did x + 30y = 1770, and then 2x + 50y = 3190, 5x + 150y = 8850, 6x + 150y = 9570 and lastly x = 720.
The required cost of one charter bus would be 720 dollars.
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
Let's assume that cost to charter one bus would be x and the spend on the student would be y
According to the given situation, we can write the equations as
x + 30y = 1,770 ....(i)
2x + 50y = 3,190 or
x + 25y = 1,595 .....(ii)
Subtracting equation (ii) from equation (i), and solving for y
x + 30y - (x + 25y) = 1,770 - 1,595
5y = 175
y = 35
Substitute the value of y= 35 in the equation (i), and solve for x
x + 30(35) = 1,770
x + 1,050 = 1,770
x = 1,770 - 1,050
x = 720
Therefore, the cost of one charter bus would be 720 dollars.

Answer:
198.57 cm^2
Step-by-step explanation:
If we join the 2 semi circles, we get a circle.
We can A = pi*r^2
d= 10, r = 5
Area of circle = pi*5^2 ,
= 25*pi
Since diameter= 10 vertically, it should be 10 horizontally too, but it's divided into 2 because of the 2 semi circles.
Thus, width of each semi circle is 5 cm.
Area of rectangle = l *b
Area = (22-10)*10
Area = 12*10
= 120 cm ^2
Total area = 25pi + 120
= 120 + 25(22/7)
= 120 + 78.57
= 198.57
