Find the area of this parallelogram.
5 cm height
7 cm width
Answer:
35 cm^2
Step-by-step explanation:
To find the area you need to find the width and height which we have.
Now all you need to do is to use the formula Height x Width= area
so replace height with 5 cm and width with 7 cm
5 cm x 7 cm = area
5 times 7 is 35 so the area of the parallelogram is 35 cm^2 (cm times cm is cm^2)
Hope this helps!

A student cycles a distance of 63 km in less
than 3 hours. What is the average speed?
Answer:
About About 21 km/h
Step-by-step explanation: If they travel 63 km in 3 hours then all it is is just 63 divided by 3 or 63/3.
The average speed for the cycle will be 21 km per hour.
What is an average speed?Speed is defined as the ratio of the time distance traveled by the body to the time taken by the body to cover the distance. Speed is the ratio of the distance traveled by time. The unit of speed in miles per hour.
The average speed is defined as the ratio of the total distance traveled and the total time taken by the object.
Given that A student cycles a distance of 63 km in less than 3 hours. The average speed is calculated as:-
Average speed = Distance / time
Average speed = 63 / 3
Average speed = 21 km / hr

7. Of the three explanations below, which person gives the best explanation of why the LSRL is the best line of best fit?
Explain your choice.
Thomas: The LSRL is the best line of
best fit because it touches the most
points on a scatterplot when graphed.
Keene: The LSRL is the best line of best fit
because it has the smallest value for all the
squared residuals added together.
Ella: The LSRL is the best line of best fit because the sum of the residuals is closest to zero when they are all
added together.

graph the following function on the axes provided.
Answer:
Step-by-step explanation:
The graph of the piecewise function is attached below.
How to graph the following function on the axes provided?Function is a type of relation, or rule, that maps one input to specific single output.
The piecewise function is given as:
f(x) = - 6 for -6< x < 1
-2x + 5 for 1< x < 6
The above means that we plot the function on their interval or domain.
i.e. we plot f(x) = - 6 on the interval x < 0 and f(x) = -2x + 5 on the interval x < -6
Next, we plot the graph of the piecewise function.
Thus, The graph of the piecewise function is attached below.

Step-by-step explanation:
An independent study commissioned by the stadium showed that running a cable TV ad 5 times daily for a week generated 1,200 ticket sales. The stadium wants to sell out an upcoming show, which requires the sale of 13,200 tickets. How long should the stadium run the cable ad in order to reach this target?
Answer
I think 55 times
Step-by-step explanation:
13,200/1,200 = 11
5/1200 = x/13,200
so if 1,200*11=13, 200 then 5*11= 55.
btw , could u give me the brainliest if i am right?
The total time the stadium runs the cable ad in order to reach this target is 11 days and this can be determined by using the unitary method.
Given :
Running a cable TV ad 5 times daily for a week generated 1,200 ticket sales. The stadium wants to sell out an upcoming show, which requires the sale of 13,200 tickets.The following steps can be used in order to determine the total times the stadium run the cable ad in order to reach this target:
Step 1 - The unitary method can be used in order to determine the total times the stadium runs the cable ad in order to reach this target.
Step 2 - According to the given data, running a cable TV ad 5 times daily for a week generated 1,200 ticket sales.
Step 3 - If running TV ad 5 times daily sales 1200 tickets then to sell 13200 tickets the total times the ad is running is:
[tex]=\dfrac{13200}{1200}\times 5[/tex]
= 55 times
Step 4 - Now, if 5 times ad running in one day then 55 times ad running in:

Deandre is going bowling with some friends. It costs $5 to rent a pair of bowling shoes & $3 per game. If Deandre spent $11, how many games did he bowl?
Answer:
2
Step-by-step explanation:
He played 2 games because he already paid $5 to rent a pair of bowling shoes and each game cost $5. So all you have to do is add 5+3 and that would give you 8. That's not quit 11 yet so add another 3. 8+3 would equal 11.

Identify the property on this equation 5(a + 3b) = 5a + 15b
Answer:
??????????????????????
Step-by-step explanation:
Answer: Distributive Property
The term "distribution" is also used in place of "distributive"
This property says
x*(y+z) = x*y + x*z
We multiply the outer term x with each inner term (y and z). Then we add the results.
In this case,
x = 5
y = a
z = 3b
So,
5(a+3b) = 5*a + 5*3b = 5a+15b

A line with a positive slope is parallel to one of the lines shown. What is its slope? Use the graph shown below.
Answer:
2/5
Step-by-step explanation:
first select the line that is positive which is the purple one
slope = change in y / change in x
two clear points are (0,2) and (5,4)
so you do y2-y1 / x2-x1
=(4-2)/(5-0)

In the last quarter of a high school football game, your team i s behind by 21 points. A field goal is worth 3 points and a touchdown (after the extra point is worth 7 points. Let x represent the number of field goals scored and y represent the number of touchdowns scored. Write an inequality that models the different number of field goals and touchdowns your team could score to win the game. (Assume the other team doesn't score any more points.)
Answer:
3x + 7y > 21
Step-by-step explanation:
3x + 7y > 21
where:
x = number of field goals needed to win
y = number of touchdowns (plus extra point) needed to win
Since your team is 21 points behind and you want to win the game, not tie it, the number of field goals and touchdowns must result in a number higher than 21, not equal to or higher than.
Answer:
3x + 7y > 21

1/2y+5=-10
Step 2: Subtract 5 from both sides.
1/2y+5-5=-10-5
1/2y+-15
