A little league baseball team is ordering hats. The graph shows the relationship between the total cost, in dollars, and the number of hats ordered.
What does the slope of the graph tell us in this situation?
The slope tells us that the cost increases as the number of ordered hats increases.
Given,
A little league baseball team is ordering hats.
The graph shows the relationship between the total cost, in dollars, and the number of hats ordered.
We need to find out what the slope of the graph tells us in this situation.
What is the slope of a graph?The slope in a graph tells us the relationships between the data on the x-axis and the y-axis.
The points on the slope give the relationships between the particular point on the x-axis and the y-axis.
The slope tells us the rate of change of y relative to x.
We see that,
If the number of orders of hats is 1, the total cost is $50.
1 order = $50
Similarly,
2 order = $60
3 order = $80
4 order = $90
5 order = $100
6 order = $120
7 order = $130
8 order = $150
9 order = $160
10 order = $170
11 order = $190
We see that as the order of hats increases the cost also increases.
Thus the slope tells us that the cost increases as the number of ordered hats increases.

Answer: D. 10x^2 + 4x + 3
To find the combined area, add both of the areas together.
A = (3x^2 - x + 7) + (7x^2 + 5x - 4) (Remove the parentheses)
A = 3x^2 - x + 7 + 7x^2 + 5x - 4 (Combine the like terms)
A = 10x^2 + 4x + 3
∴ the combined area of Tiffany's fence and lawn is 10x^2 + 4x + 3.

Answer:
y = 1/7x + 23/7 or y = 1/7x + 3 and 2/7
Step-by-step explanation:
If you are learning about this, I suppose you know the formula or how to get the slope. You want to divide the rise over run or take the two y values divided the two x values:
[tex]m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
The two points we have are (-2, 3) and (5, 4)
So:
4 - 3 / 5 - (-2)
1 / 5 + 2
Slope: 1 / 7
Now we want to find b in y = mx + b,
We can write it as y = 1/6x + b, then plug in a y and x value:
3 = 1/7(-2) + b
3 + 2/7 = b
b = 23/7
We can check by using the other point we have:
4 = 1/7(5) + b
4 - 5/7 = b
b = 23/7 or 3 and 2/7
Then the equation is: y = 1/7x + 23/7

==============================================
Explanation:
For now, focus on triangle COA.
Since OC and OA are the two radii, this means OC = OA. Furthermore, it means triangle COA is isosceles.
Any isosceles triangle has its base angles congruent to one another. In this case, the base angles are A and C. Both are equal to lowercase 'a'.
So now we know that triangle COA has angles A = a, C = a, O = 54. The three angles of any triangle add to 180
C+O+A = 180
a+54+a = 180
2a+54 = 180
2a = 180-54
2a = 126
a = 126/2
a = 63
---------------------------
Now turn your attention to triangle ABC. This is a right triangle (due to Thales Theorem). The right angle is at angle C, so C = 90.
Use the same idea as before to find b
A+B+C = 180
a+b+90 = 180
63+b+90 = 180
b+153 = 180
b = 180-153
b = 27

Which point is located in quadrant IV?
(–2, –4)
(–2, 4)
(2, –4)
(2, 4)
Answer:
(-2, 4)
Step-by-step explanation:
If you look at the quadrants on the graph, you could see that quadrant I holds only positive values (+, +). For quadrant II, it would hold (-, +) values. For quadrant III, it would hold (+, -) values. Lastly quadrant IV would hold (-, -) values.
So to answer the question, only (-2, 4) would be correct.
I also attached a graph of all the quadrants for you, just to understand the where all the positive and negative values are on the graph when it comes to quadrants.

a person bikes 2 1/2 miles at constant rate in 1/8 of an hour what distance , in miles , does the person bike in an hour
Answer: The person bike 20 miles in an hour.
Step-by-step explanation:
Given: At a constant speed, a person travels [tex]2\dfrac12[/tex] miles in [tex]\dfrac18[/tex] hour.
As [tex]2\dfrac12=\dfrac{2\times2+1}{2}=\dfrac{5}{2}[/tex]
So, in [tex]\dfrac18[/tex] hour, distance traveled = [tex]\dfrac52[/tex] miles
As time and distance are proportional, Multiply 8 om both sides , we get
In 1 hour, distance traveled = [tex]\dfrac52\times8[/tex] miles
[tex]=5\times4[/tex] miles= 20 miles
Hence, the person bike 20 miles in an hour.

A rectangular swimming pool measures 60 meters in length and 30 meters in width. Joey creates a scale drawing of this pool using the scale 5 cm : 12 m. Find the length, width and perimeter of the pool in Joey's scale drawing. Be sure to include units in your answer.
Answer:
Length = 25cm
Width = 12.5 cm
Perimeter = 75cm
Step-by-step explanation:
Given that:
Actual measurement of rectangular swimming pool:
Length = 60 m
Width = 30 m
Scale = 5cm : 12 m
dimension of scale drawing
Length = 5/12 * 60 = 25cm
Width = 5/12 * 30 = 12.5cm
Perimeter of Scale drawing :
2(length + Width)
2(25cm + 12.5cm)
2(37.5cm)
= 75cm

The smaller brackets around 2 indicate that minus is being multiplied by 2 making it -2. As the signs of 1and 3 are the same i.e + they both are added and the answer is 4. Now 4 has the +ve sign and 2 has the -ve sign so 2 is subtracted from 4 and we get a +ve 2 . Now 2 raise to power 3 gives 8 which is the required number.
Only 2 raised to power 3 gives a 8. any other number like 3 or 1 raise to power does not give an eight.
