The system of equations needed to solve the given equations is . Thus, the correct graph is the top-right graph. Its plotted below.
How to find the system of equations needed to solve an equation?
An equation usually consists of equality of two mathematical expressions. Let it be
�
=
�
A=B . If we take them to be equal to third variable, then:
�
=
�
=
�
A=B=C type of equation is obtained.
We can then take it as system of two equations as:
�
=
�
�
=
�
A=C
B=C
Solution to this system will give us the solution to the considered equation
What is a solution to a system of equations?
For a solution to be solution to a system, it must satisfy all the equations of that system, and as all points satisfying an equation are in their graphs.
For the given case, we are given that:

and

Plotting these two functions on the X-Y plane, the common point of these curves is the common value which can satisfy both the equations simultaneously, and thus, being the solution to the considered system of equations.
Thus, the solutions are those two points that are intersections of those two curves.

cone A and cone B are similar. The radius of cone a is 5.4 feet and the radius of cone b is 16.2 feet. if the surface area of cone a is 43 square feet, find the surface of cone b
Answers
The surface area of cone B is 387 square feet.
What is a cone?It is a shape of a christmas tree where there is a base of radius r and a top point called the apex.
We have,
Since the cones are similar, their corresponding dimensions are proportional.
In particular, the ratio of their radii is equal to the ratio of their surface areas.
Now,
Let S be the surface area of cone B, then we have:
ratio of radii = 16.2/5.4 = 3
ratio of surface areas = S/43
Since the ratio of surface areas is equal to the ratio of radii squared,
We have:
3² = S/43
9 = S/43
S = 9 x 43
S = 387
Therefore,
The surface area of cone B is 387 square feet.

Step-by-step explanation:
Step one: look at the figure...it's a 90º angle (right angle)
Step two: Since it's a 90º angle you can simply subtract 90-52 which will give you the missing part (the value of x)

The solution set of the given inequality is {.......,-3, -2, -1, 0, 1, 2, 3, 4, 5}. Therefore, option D is the correct answer.
What are inequalities?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
The given inequality is x<6.

Step-by-step explanation:
The median can be found at the line inside of the box, the heaviest weight would be found at the right end of the line, and the smallest weight would be found at the left, the interquartile range is the difference of one end of the box to the other, and the range is the difference of the largest number of the entire diagram, from the smallest number.
Hope this helps you!
Answer:
Florida: The weight range = 10
Tennessee: The interquartile range = 4
Tennesse: Median Weight = 76
Florida: Median Weight = 80
Florida: Weight of the heaviest child = 84
Tennesse: Weight of the smallest child = 71
Step-by-step explanation:
Florida: How to find the weight range
The range of a data set is the difference between the minimum and maximum. To find the range, calculate xn minus x1.
R = xn − x1
Therefore, the weight range in Florida is 10
Tennessee: How to find the interquartile range
To find the interquartile range (IQR), first, find the median (middle value) of the lower and upper half of the data set. These values are quartile 1 (Q1) and quartile 3 (Q3). The IQR is the difference between Q3 and Q1.
71, 72, 73, 74, 75, 76, 77, 78, 79, 80
Q1 = 74
Q2 = 78
78 - 74 = 4
Therefore, the interquartile range in Tennesse is 4
Tennesse: Median Weight
The median x˜ is the data value separating the upper half of a data set from the lower half.
Arrange data values from lowest to the highest value
The median is the data value in the middle of the set
If there are 2 data values in the middle the median is the mean of those 2 values.
x˜ = 75.5
Therefore, the median weight of Tennesse is 76
Florida: Median Weight
The median x˜ is the data value separating the upper half of a data set from the lower half.
Arrange data values from lowest to the highest value
The median is the data value in the middle of the set
If there are 2 data values in the middle the median is the mean of those 2 values.
x˜ = 79
Therefore, the median weight of Florida is 80
Florida: Weight of the heaviest child
Since the smallest number in Florida is 84,
Therefore, the weight of the heaviest child in Florida is 84
Tennesse: Weight of the smallest child
Since the smallest number in Tennesse is 71,
Therefore, the weight of the smallest child in Tennesse is 71
