Answer:
60 km/h
Step-by-step explanation:
The decreasing part is from (20,13) to (60,6), which gives an average rate of
Then, we have an increasing part from (60,6) to (120,10), which gives an average rate of
Basically, at 60 km/h the fuel used was 6 liters per 100 kilometers. Notice that the other velocities make the car to use more liters per kilometers.

Answer:
8.625 ft, second option
Step-by-step explanation:
For the rectangles:
1.5 * 2.5 = 3.75
So, 3.75 ft for one rectangle
But there are two rectangles, so:
3.75 * 2 = 7.5
So now the area is 7.5ft for both rectangle.
For the triangle:
Triangle formula - 1/2 × Base × Height
In this case both the base and the height are 1.5 so next step is multiplying by plugging in the numbers
1/2 * 1.5 * 1.5 = 1.125
So the area for the triangle is 1.125 ft
Total area:
Now you just add the numbers you got which is 7.5 and 1.125
7.5 + 1.125 = 8.625
The area is 8.625 ft
What is the median for the data shown below? Test Scores Stem Leaves 6 8 7 0 8 0, 6, 8, 8, 9 6, 6, 7, 7, 8, 8, 9 10 0, 0, 0, 0, 0 6|0 = 60 years old 100 97 92 32
Answer: I believe it would be 0.
Step-by-step explanation:
The median is 97.
Using the stem-and-leaf plot in the diagram, below, write out each data points given, which are:
68, 70, 80, 86, 88, 88, 96, 96, 97, 97, 98, 98, 99, 100, 100, 100, 100, 100
The line plot for these data would have the following frequency for each data point:
68 - 1 dot
70 - 1 dot
80 - 1 dot
86 1 dot
88 - 2 dots
96 - 2 dots
97 - 2 dots
98 - 2 dots
99 - 1 dot
100 - 5 dots
Range = 100 - 68 = 32
Median = 97
Therefore, the median is 97.

b. 2.5 inches. 20/8=2.5
a. 10.125 inches. 81/8 = 10.125
The answer for a) is 10.125 inch and b) is 2.5 inch, 1.875 inch
What is an inch?Inch is a unit of linear measure equal to one twelfth of a foot (2.54 cm).
a) According to the question the real time length of the court is 81 ft
But from the question 1 inch in diagram is equal to 8 ft
So, 81/8=10.125
Thus the entire length of the court if it is 81 ft in real life is 10.125 inch
b) According to the question the real time length and width of receiver A is 20ft and 15ft
So, in diagram it could be in
length is 20/8 = 2.5 inch
width is 15/8 = 1.875 inch
Thus the length and width of receiver A is 2.5 inch, 1.875 inch

Answer:
x=13
Step-by-step explanation:
mugs=x
key=y
x+y=21 8.5x2.75 =132.50
y= -x+21
8.5x + 2.75 (-x + 21) = 132.50
8.5x - 2.75 + 57.75 = 132.50
5.75x = 74.75
x= 13

Answer:
he bought 13 coffee mugs and 8 key chains.
Step-by-step explanation:
How about we solve by simulataneousequation:
consider coffee mug 'x' and key chain 'y'
there are total 21 items,
x+y = 21
=> x = 21 - y .........................(i)
and
total cost is $132.50
8.5x + 2.75y = 132.5 .........(ii)
put value of x from eqn (i) into (ii):
8.5 ( 21 -y) + 2.75y = 132.50
=> 178.5 - 8.5y + 2.75y = 132.50
=> -5.75y = -46
=>y = 8
Put vaklue of y back in (i):
x = 21 - y
=> x = 21 - 8 = 13
thus, x = 13
he bought 13 coffee mugs and 8 key chains.
y = 3x − 8
y = 9x − 11
Part A: Using your own words, explain how to solve the pair of equations graphically. Write the slope and y-intercept for each equation that you will plot on the graph to solve the equations.
Part B: What is the solution to the pair of equations?
Answer:
A. You would first plot the y intercept. The first equation would be (0,-8) and the second equation is (0,-11). Then you would plot the slope. For the first equation, from (0,-8), you would move up 3 plots and right 1 plot. For the second equation, from (0,-11), you would move up 9 plots and right 1 plot.
B. The solution to the pair of inequalities is (1/2, -13/2). That is the intersection and point of the two lines. You would need to graph the two lines (see part A answer) and then find the intersection.

name at least two independent variables that could result in a change in a monthly electric bill
ill give thanks and brainliest ;-;
(please i had to repost since a bot answered my last questions, waste of my 20 points
Answer: There are often not more than one or two independent variables tested in an experiment, otherwise it is difficult to determine the influence of each upon the final results. There may be several dependent variables, because manipulating the independent variable can influence many different things.
Two independent variables that could result in a change in the monthly electricity bill are: Physical size of products and Skill level of operators of machines.
Independent VariablesIndependent variables are the determining factors that influence how a dependent variable changes.
For example, monthly electricity bill is a dependent variable which is dependent on the following:
Physical size of productsSkill level of operators of machines.Non-production machines utilizing electricity among others.Therefore, two independent variables that could result in a change in the monthly electricity bill are: Physical size of products and Skill level of operators of machines.
