Step-by-step explanation:
Jamilia has a weather station in her backyard. She uses a rain gauge to track the total rainfall during two storms.
1: Jamilia graphs the function describing mondays rainfall. Is the graph linear or nonlinear? How do you know?
2: what is the real-world meaning of the slope of the graph?
3: Next, Jamilia graphs the function describing Thursday’s rainfall. Is this graph linear or nonlinear? How do you know?
4: What does the y-intercept of the graph or Monday’s storm mean? Does the y-intercept of the graph of Thursday’s storm have the same meaning?
Answer:
1. The graph is linear because the precipitation increases at a steady rate of 3 mm every 15 minutes, or 0.2 mm per minute.
2.The slope of a line tells us how something changes over time, if the slope is found, the rate of change can be found. In this case it is telling us how the rain increases over time.
3.The graph is nonlinear. Because the rainfall total does not change at a constant rate, the points do not form a line.
4.The y intercept means the total rain that was present at the start of her recording, this means there was no rain when she first started her experiment.
Step-by-step explanation:
A linear function is such that has a constant rate, while a nonlinear function does not have a constant rate.
1. Monday rainfall
From the table that represents Monday rainfall, we have the following observations
As the time increases, the precipitation increases at constant interval.Time increases constantly by 15 minutes, precipitation increases constantly by 3 mmThis means that, the graph is a linear graph.
2. The slope
The slope in this case, is the amount of precipitation in one minute
3. Thursday rainfallFrom the table that represents Thursday rainfall, we have the following observations
As the time increases, the precipitation increasesTime and precipitation do not increase constantlyThis means that, the graph is a nonlinear graph.
4. The y-intercept
This is the value of precipitation when the time is 0
From the table,
The precipitation at 0 minute is 0
Hence, the y-intercept, is 0
And yes, both graphs have the same y-intercept

Kwame is not sure whether to use a line graph or a line plot to display the data. Which best explains which graph is a better representation of the data?
The line graph because it shows how the number of miles increases over the number of minutes.
The line graph because the numbers in the data table are equally spaced.
The line plot because numbers can be plotted on a number line.
The line plot because there are only a few data points.
Answer:
The line graph because it shows how the number of miles increases over the number of minutes.
Step-by-step explanation:
ake it or leave it
The best explanation graph is a better representation of the data below: "The line graph because it shows how the number of miles increases over the number of minutes."
What is a graph?A graph can be defined as a visual representation or a diagram that represents data or values.
The distance in miles a car travels over time in minutes is shown in the table.
Distance (miles) Time (minutes)
10 15
20 30
30 45
40 60
A line graph is a good choice for representing data that show a change in value over time. In this case, the value being measured is the distance in miles traveled, and the time is being used as the variable. A line graph is a good choice because it can show the change in distance over time, which is what the data represents.
Hence, the correct answer would be an option (A).

A store sells toys in bulk. It sells wooden blocks for $5 a pound and plastic bricks for $10
a pound. How many pounds of wooden blocks and plastic bricks should be used to make a
10-pound mixture that would sell for $80?
9514 1404 393
Answer:
6 # plastic bricks4 # wooden blocksStep-by-step explanation:
Let p represent the number of pounds of plastic bricks in the mix. Then the number of pounds of wooden blocks is (10-p), and the total cost is ...
10p +5(10-p) = 80
5p = 30 . . . . . . . . . subtract 50
p = 6 . . . . divide by 5; there are 6 pounds of plastic bricks in the mix
4 pounds of wooden blocks and 6 pounds of plastic bricks should be used to make a 10-lb mix worth $80.

-6h + 2(4h + 3) = 1
Please provide your best explanations, as well as showing the step you took and the finished equation.
Solve for h.
Thank you!
Answer:
h = -2.5
Step-by-step explanation:
Apply the distributed property: -6h + 8h + 6 = 1Combine like terms: 2h + 6 = 1Subtract 6 from each side, so it now looks like this: 2h = -5Divide each side by 2 to cancel out the 2 next to h. It should now look like this: h = -2.5I hope this helps!
Answer:
h = -2.5
Step-by-step explanation:
-6h + 2(4h + 3) = 1
-6h + 2*4h + 2*3 = 1
-6h + 8h + 6 = 1 {combine like terms}
2h + 6 = 1
2h = 1 - 6
2h = -5
h = -5/2
h = -2.5

Item 8 A container has peppermint gum and spearmint gum. There are 18 pieces of peppermint gum in the container and the ratio of peppermint gum to spearmint gum is 2 : 3. Find the number of pieces of spearmint gum in the container.
Answer:Number of Spearmint gum = 27 pieces
Step-by-step explanation:
step 1
Let the total number of peppermint gum and spearmint gum in the container = X
Ratio of peppermint gum to spearmint gum= 2 : 3.
Total ratio = 2+ 3=5
Step 2
we were given that peppermint gum= 18 pieces , so total number of gums will be calculated as
Ratio of peppermint/ Total ratio x Total number of gums = Number of peppermint
2/5 x X= 18
X=(18X 5) / 2 = 45
X= Total number of gums = 45
Number of spearmint gum will now be
Ratio of spearmint/ Total ratio x Total number of gums = Number of spearmint
3/5 x 45= 27
Therefore Number of Spearmint gum = 27 pieces

Jerry scored 581 points by collecting 7 coins. In all, how many coins does Jerry have to collect to score a total of 996 points? Solve using unit rates.
Answer:
12 coins
Step-by-step explanation:
Points scored by collecting 7 coins = 581
Number of coins required to collect 996 points
Let Number of coins = c
7 coins = 581 points
c coins = 996 points
Cross multiply :
581 * c = 996 * 7
581c = 6972
Divide both sides by 581
581c / 581 = 6972 / 581
c = 12
Hence, number of coins required to collect 996 points is 12
which ordered pair is a solution of the equation: 2y=7x-3
only 2,4
only 3,9
both 2,4 and 3,9
neither
Answer:
It is only 3,9.
Step-by-step explanation:
You need to substitute each pair into the equation to find if both side have the same answer, 3,9 is the correct answer because both sides are equal:
2(9) = 7(3)-3
18= 18
The answer is (3,9).

What is a linear function?The terms "linear function" in mathematics refer to two different but related ideas: A linear function is a function with a graph that is a straight line in calculus and related fields.
The given data in the table is:-
X -7.5 -3.5 -1 2
Y 12 0 -7.5 -16.5
The linear function can be written as:-
y = mx + c
m = ( 0 - 12 ) / ( -3.5 + 7.5 )
m = -12 / 4
m = -3
The y-intercept will be:-
y = mx + c
0 = ( -3 x -3.5 ) +c
c = -10.5
The linear function is:-
h(x) = -3x - 10.5
