Final answer:
John and Ramona are closing in on each other on a collision course with a combined speed of 35 mph over a distance of 24 miles. After doing the calculation, we find that it will take them approximately 41.14 minutes to meet.
Explanation:
To find out how long it will take John and Ramona to meet, we can assume they are moving towards each other on a collision course. We do this by adding their speeds together since they are moving in opposite directions. John cycles at a speed of 20 mph and Ramona cycles at 15 mph, so the combined speed at which they are closing in on each other is 20 mph + 15 mph = 35 mph.
The distance between them is 24 miles. To calculate the time it takes for them to meet, we divide the total distance by their combined speed:
Time = Distance / Speed
Time = 24 miles / 35 mph
Time = 0.6857 hours
Since time is often represented in minutes, we multiply the decimal by 60:
0.6857 hours * 60 minutes/hour = 41.14 minutes
Therefore, it would take approximately 41.14 minutes for John and Ramona to meet.
the current temperature of 12 degrees Fahrenheit below zero is 29 degrees Fahrenheit below the high temperature of the day. what is the high temperature for the day?
A. -41 degrees Fahrenheit
B. 17 degrees Fahrenheit
C. 19 degrees Fahrenheit
D. 41 degrees Fahrenheit
Answer:
12 degrees Fahrenheit below zero is simply -12 degrees. And since -12 is lower by the number by 29 degrees, we just add 29 to -12
Step-by-step explanation:
-12
+29
=17
The high temperature of the day is +17 degrees.
Pls mark brainliest :)
The temperature of the day is 17 degrees Fahrenheit.
Given data:
To find the high temperature of the day, add the temperature difference to the current temperature.
The temperature difference is 29 degrees Fahrenheit below the high temperature of the day.
Given that the current temperature is 12 degrees Fahrenheit below zero, determine the high temperature by adding the temperature difference:
High temperature = Current temperature + Temperature difference
On simplifying the equation:
High temperature = -12 degrees Fahrenheit + 29 degrees Fahrenheit
High temperature = 17 degrees Fahrenheit
Hence, the high temperature for the day is 17 degrees Fahrenheit.
The correct answer is B. 17 degrees Fahrenheit.

Graph the equation by translating y = |x|. y = |x+2|
To graph y = |x+2|, consider the parent function y = |x| and translate it 2 units to the left. Choose x-values, find the corresponding y-values, and plot the points. Connect the plotted points to obtain the graph of y = |x+2|.
Explanation:To graph the equation y = |x+2|, we will first consider the parent function y = |x|, which is a V-shaped graph that passes through the origin. Translating the graph y = |x| to the left by 2 units gives us y = |x+2|.
To plot the graph, we can choose various x-values and find the corresponding y-values. For example, when x = -4, y = |(-4)+2| = 2. Similarly, when x = -2, y = |(-2)+2| = 0. We can continue this process to find more points and then plot them on a coordinate plane.
By connecting the plotted points, we will obtain the graph of y = |x+2| which will be a V-shaped graph shifted 2 units to the left.
A triangle with sides of lengths 32,60,68 is a right triangle ? True or false
Answer:
True
Step-by-step explanation:
Using the converse theorem of Pythagoras
If the longest side in a triangle is equal to the sum of the squares of the other 2 sides then the triangle is right.
longest side = 68
68² = 4624
and 32² + 60² = 1024 + 3600 = 4624

You have $1 and earn $0.25 for each cup of orange juice you sell. Write an equation in two variables that represent the total amount A (in dollars) you have after selling j cups of orange juice. ASAP I need it to turn in today
Answer:
A = 0.25*j + 1
Step-by-step explanation:
The question presented here is an application of linear models. The $1 amount is fixed and does not depend on any factor such as the cups of orange juice sold.
Furthermore, we are informed that we earn $0.25 for every cup of orange juice sold. This means that we shall earn 0.25 j by selling j cups of orange juice.
The variable total amount, A will thus depend on the fixed amount of $1 and the variable income 0.25 j.
The equation in two variables that will represent the total amount A (in dollars) you have after selling j cups of orange juice will thus be;
A = 0.25*j + 1
the amount after selling y cups is can be given by the equation [tex]x = 1 + 0.25y[/tex]
Let x be the amount we have and y be the number of cups of orange juice sold.
We start with $1, so this is your initial amount. For each cup of orange juice sold, you earn $0.25.
Therefore, total earnings by selling y cups will be:
[tex]0.25y[/tex]
The equation can be written as follows:
[tex]x = 1 + 0.25y[/tex]
Thus the amount after selling y cups is can be given by the equation [tex]x = 1 + 0.25y[/tex]
What is the largest of three consecutive positive integers if the product of the two smallest is equal to 2 more than 8 times the longest.
Answer:
11Step-by-step explanation:
n, n + 1, n + 2 - three consecutive integers
The equation:
n(n + 1) = 8(n + 2) + 2 ust the distributive property
n² + n = 8n + 16 + 2
n² + n = 8n + 18 subtract 8n from both sides
n² - 7n = 18 subtract 18 from both sides
n² - 7n - 18 = 0
n² - 9n + 2n - 18 = 0
n(n - 9) + 2(n - 9) = 0
(n - 9)(n + 2) = 0 ⇔ n - 9 = 0 or n + 2 =0
n - 9 = 0 add 9 to both sides
n = 9
n + 2 = 0 subtract 2 from both sides
n = -2 < 0
n + 2 = 9 + 2 = 11

Answer:
The correct option is 1.
Step-by-step explanation:
It is given that the box plot shows the number of books sold each day at a store for 80 days.
A box plot is drawn with end points at 0 and 16. It means minimum value is 0 and maximum is 16.
The box extends from 2 to 12. It means first quartile is 2 and the third quartile is 12. A vertical line is drawn inside the box at 7, it means median is 7.
He have to find the number of days in which the bookstore sell 2 to 12 books.
2 is first quartile and 12 is third quartile, we know that
[tex]Q_1=25\%[/tex]
[tex]Q_3=75\%[/tex]
[tex]Q_3-Q_1=75\%-25\%=50\%[/tex]
The data lies between Q₁ and Q₃ is 50% of the data.
[tex]80\times \frac{50}{100}=40[/tex]
The bookstore sell 2 to 12 books in 40 days.
Therefore, the correct option is 1.

PLEASE HELP, TWENTY POINTS!!!!!!!!!!! Ezra earns 20% commission as a sales person. He sold a grandfather clock that cost $968.70. How much commission did Ezra earn?
Answer:
193.74 is the swear
Step-by-step explanation:
What you can do is divide 20 by 10 to get 0.20. Then you multiply by 968.70
So 0.20 x 968.70 = 193.74
So 193.74 is the commission Ezra earned.
To check the answer you just add it like this 100% +20% or 0.20
Then multiply that like this 120% is 1.20, so 1.20 x 968.70 = 1,162.44
to check you just inverse it 1,162.44 - 968.70 = 193.74.
So it is accurate.

Sakiya surveyed students in her school about their favorite sports.On Monday,she randomly surveyed 85 students in the cafeteria.On Tuesday,she surveyed 15 of her teammate on the soccer team.Which statement best describes the samples Sakiya used?
A)Neither sample represents the school population.
B)Both samples likely represent the school population.
C)The data gathered on Tuesday most likely represent the school population,but the data gathered on Monday most likely do not.
D)The data gathered on Monday most likely represent the school population,but the data gathered on Monday most likely do not.
Pls help
Answer:
I think its D
Step-by-step explanation:
Also Do you mean D)The data gathered on Monday most likely represent the school population,but the data gathered on Tuesday most likely do not?
The data gathered on Monday by randomly sampling 85 students will most likely represent the school population, whereas the data from Tuesday, consisting of Sakiya's soccer teammates, is a convenience sample and likely does not represent the school population.
Explanation:The student's question involves understanding how well a sample represents a larger population in statistical surveying. In Sakiya's case, the first sample where she surveyed 85 randomly chosen students in the cafeteria on Monday is more likely to represent the school population because it was randomly selected from a broader, more diverse group. This is in contrast to the sample gathered on Tuesday, which includes only 15 of her soccer teammates and is a convenience sample, since it's composed of individuals who are readily accessible to the researcher but may not represent the target population accurately.
Therefore, it's reasonable to conclude that the Monday sample is better at representing the entire school population due to the randomness of the selection process. In contrast, the Tuesday sample is biased and less representative because it consists of a specific subgroup within the school, i.e., soccer team members, who may share similar interests that do not necessarily reflect the interests of the entire school population.

The sum of the internal angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
here n = 5, hence
sum = 180° × 3 = 540°
Each exterior angle plus interior angle = 180°
Subtract each exterior angle from 180 for corresponding interior angle.
180 - 59 = 121, 180 - 77 = 103, 180 - 66 = 114, 180 - 62 = 118
Sum the 4 interior angles and subtract from 540 for 5 th interior angle
5 th = 540° - (121 + 103 + 114 + 118)° = 540° - 456° = 84°
The 5 th interior angle and 12x sum to 180 ( same reason as above )
Hence
12x + 84 = 180 ( subtract 84 from both sides )
12x = 96 ( divide both sides by 12 )
x = 8
