The average number of points scored by athlete per game is 21.
It is given that a star athlete scored 649 points during the 31 basketball games.
We have to find , the average number of points she scored per game.
What will be the value if 24 is divided into 8 parts equally ?
The value will be 3.
Total points scored in 31 basketball games = 649 points
Points scored in 1 game =
649 ÷ 31
= 20.93
≈ 21 points per game
Thus , the average number of points scored by athlete per game is 21.

Step-by-step explanation:
Angle CAB = 180° - 133° = 47° (Angles on a Straight Line add up to 180°)
Angle ACB = 180° - 90° = 90° (Angles on a Straight Line add up to 180°)
Angle p or ABC = 180° - 90° - 47° = 43° (Angles in a Triangle add up to 180°)

For two matrices to be equal, they must have?
the same size and both must be diagonal matrices.
both must be square matrices.
have equal corresponding elements.
have opposite corresponding elements.
Answer:
answer is C on ED
Step-by-step explanation:
For two matrices to be equal, their corresponding elements should be equal.
What is matrix?Matrix in mathematics is the arrangement of numbers in the form of rows and columns.
A matrix is defined by a order in the form {m} x {n}, where {m} denotes the number of rows and {n} denotes the number of columns.
We can write the example of a matrix as follows. Given below is a 3 x 3 matrix. It is a square matrix.
[tex]$\left[\begin{array}{ccc}1&2&3\\4&5&6\\7&8&9\end{array}\right][/tex]
Given is to find the condition in which two matrices are equal.
For two matrices to be equal, their corresponding elements should be equal. Mathematically, for two matrices A and B, can be considered as equal if -
a{i, j} = b{i, j}
Therefore, for two matrices to be equal, their corresponding elements should be equal.

6x+6=6(x-1) is what I need help with
Steps to solve:
6x + 6 = 6(x - 1)
~Distribute left side
6x + 6 = 6x - 6
~Subtract 6 to both sides
6x = 6x - 12
~Subtract 6x to both sides

Hey there!☺
[tex]Answer:\boxed{\text{There are no solutions.}}[/tex]
[tex]Explanation:[/tex]
[tex]6x+6=6(x-1)[/tex]
6x + 6 = (6)(x) + (6)(-1) Distribute
6x + 6 - 6x = 6x - 6 - 6x Subtract 6x from both sides
6 = -6
6 - 6 = -6 - 6 Subtract 6 from both sides

Problem 18
The x should not be in the denominator. If it was in the denominator, then you wouldn't have a linear equation in the form y = mx+b
Instead, you should have written [tex]y = \frac{1}{17}x+\frac{63}{17}[/tex] or y = (1/17)x + 63/17
Comparing that to y = mx+b form, we see that m = 1/17 is the slope and b = 63/17 is the y intercept.
============================================
Problem 19
This problem isn't fully shown. The right portion is cut off. I have a feeling the same issue is happening here though. Try moving the x term like mentioned in problem 18. Also, don't forget about the "y=" portion.

Assume that each circle shown below represents one unit. Express the shaded
amount as a single fraction and as a mixed number
Answer:
One fraction = [tex]\frac{23}{12}[/tex]
Mixed Number = [tex]1\frac{11}{12}[/tex]
Step-by-step explanation:
Since each circle represents one unit,
Sum of all segments of a circle = Circle having 12 segments
If one segment of the circle is removed from one circle,
Remaining parts of the given circles = 12 + 11
Now one fraction representing the shaded sectors = [tex]\frac{12}{12}+\frac{11}{12}[/tex]
= [tex]\frac{23}{12}[/tex]
Mixed number = [tex]\frac{12}{12}+\frac{11}{12}[/tex]
= 1 + [tex]\frac{11}{12}[/tex]
= [tex]1\frac{11}{12}[/tex]

A missile flies 20 miles in 10 minutes. Calculate the missile’s rate of change. a) 2 mi/min b) 10 mi/min c) 10 min/mi d) 1/2 mi/min
Answer: The answer would be 2 miles a minute.
Step-by-step explanation: Simply divide the miles by the minutes.
Missile's rate of change is 2 mi/ min
The rate of change in this instance is the speed that the missile is going at because rate of change is used to calculate how fast something is changing in respect to time.
Speed = Distance / Time
Distance = 20 miles
Time = 10 minutes
Rate of change:
= 20 / 10
= 2 miles per minute
The rate of change is therefore, 2 mi/ min
