PLEASE HELP NOW!! James had a successful season on his basketball team. He scored a total of 160 points for the season compared to 640 pointer scored by his team as a while. What percentage of the team’s points was james responsible for?
Divide his points by teams points and multiply by 100:
160/640 = 0.25
0.25 x 100 = 25%
He scored 25% of the total points.
Answer:
25%
Step-by-step explanation:
640/140=4
james was responsible for 1/4 of the points which is equal to 0.25 when 1 is divided by 4, which times 10 is equal to 25, so the answer is 25%
Good Luck on whatever your doing!!!

Given the lengths of two sides of a triangle, find the range for the length of the third side. (Range means find between which two numbers the length of the third side must fall.) Write an inequality.
8 and 13
Explanation:
Let x be the length of the third side. We can't find the exact value of x, as we don't have enough info, but we can find possible values for x.
The lower boundary for x is 13-8 = 5. It must be larger than this value.
At the same time, x must be smaller than 13+8 = 21 as well.
So x > 5 and x < 21 becomes 5 < x < 21
In short, x is between 5 and 21. It cannot equal either endpoint.

Given a line segment that contains the points A,B,& C in order, if AB = x + 12, and Bo2.4, and AC = 26 = ?
Answer:
x=11.6
Step-by-step explanation:
According to the angle addition postulate, if B lies on AC, than AB+BC=AC.
We can use this to create this equation.
x+12+2.4=26 Where x+12 is the value of AB and 2.4 is BC.
The next step is to combine like terms, so we add 12 to 2.4 to get
x+14.4=26. When trying to find the value of a variable, you must isolate it. To do this for this equation, we must subtract 14.4 from both sides which will give you.
x=11.6

Describe how the graph of the equation relates to the graph of y = x2.
f(x) = -x + 5)2
Answer:
Step-by-step explanation:
It's y = x^2, not y = x2. The graph of y = x^2 is a parabola with vertex (0, 0) and which opens up.
The graph of y = (x + 5)^2 has the same shape as that of y = x^2, but has been translated 5 units to the left.
The graph of the function f(x) = - (x + 5)² will rotate along the x-axis and shift 5 units to the left.
What is translation?There are four different kinds of translation: stretching, shrinking, rotating, and shifting.
When shifting, the entire graph is moved in the XY direction. When expanding and contracting a graph, we do so by a factor of k. When rotating a graph, we do so either clockwise or counterclockwise.
We know the graph of the equation y = x² is a parabola that opens upwards.
Now, the graph of equation f(x) = - (x + 5)² will first rotate 180° along the x-axis as there is a change in sign y and shift x + 5 = 0 ⇒ x = - 5 shift 5 units to the left.

1. Create your own data set with an interquartile range of 17.
2. Explain how you decided which numbers to use.
3. Show the math that shows the interquartile range is 17.
Hey there! I'm happy to help!
The IQR is how far apart the first and third quartiles are, which are the middle numbers of the first and second halves of a data set. Let's find some random numbers that are 17 apart. We will use 3 and 20.
Now, we have to create a data set where 3 is the middle number of the first half and 20 is the middle number of the second half. Let's have one with six numbers because that's a good amount I guess. Remember that the data has to be going from least to greatest.
In our first half we will have one number that is smaller than 3 and one bigger than three so that 3 is in the middle. Here's an example of what our first half should look like:
2,3,5
Now, for our second half, we need a number smaller than 20 and one greater than 20 so 20 is the the middle. Here's the second half I've made for you.
16,20,100
So, the data set I've created for you is 2,3,5,16,20,100. However, there are many other possibilities as you've seen.
My answers for your question 1 and 2 are in the explanation I've done, and here's the math that shows that the interquartile range is 17.
You split the data in half.
2,3,5, 16,20,100
Q1 is the middle number of the first, which is 3. Q3 is the middle of the second, which is 20.
You find how far apart they are by subtracting 3 from 20.
20-3=17.
The IQR is 17.

Find the value of y.
Answer:
y is 3.6
Step-by-step explanation:
The information given are
Parallel lines crossing two converging lines with proportion 3 and 5 on one and 6 and y on the other
To find y, we have that two or more parallel lines cut by two transversal proportionately cut the transversal lines;
Therefore we have from the measured segment of the two lines;
[tex]\dfrac{3}{5} = \dfrac{y}{6}[/tex]
Which gives;
3 × 6 = 5 × y
y = 3 × 6/5 = 18/5
y = 18/5 = [tex]3\frac{3}{5}[/tex] , which is equal to 3.6.

FIRST GETS BRAINLLEST If the triangle below is enlarged by a scale factor of 2, what will be the perimeter of the new triangle? 16 units 19 units 21 units 24 units
There are two ways to do this. The first method you would multiply each original side by 2 to get 7 for each side. The new perimeter would be 7+7+7 = 21.
Or you could find the perimeter of the original figure (3.5+3.5+3.5 = 10.5) and then multiply that by 2 to get the same result (10.5*2 = 21)

Answer:
49π
Step-by-step explanation:
Circle area: πr^2
Since A to C is 14, and they're both in the center, A to B and B to C will both be 7 as a radius.
Since we know the radius, we can put it in the formula, πr^2.
We only need to solve for one circle, since both circles are the same. By solving the circle, we will put in 7 for the radius, giving us π7^2, which is 49π.

The height of the trunk is 26 inches the length of the trunk is 50 inches. The tv is 54 inches wide. And 96 inches in height. Assuming the trunk is at least 96 inches deep can the tv fit into the trunk? Explain
Answer:
It states that assuming the trunk is 96" long. So with that information assuming the trunk is at least 96 inches deep and the tv is 96” long and the length of the trunk diagonal is 56.36” which is greater than the TV length 56”, so the TV will fit diagonally in the trunk.
Step-by-step explanation:
The length of the diagonal of the trunk is 56.356011 inches.
What is Pythagoras Theorem?A theorem stating that the square of the length of the hypotenuse of a right triangle is equal to the sum of the squares of the lengths of the other sides.
Given:
height of the trunk= 26 inches
length of the trunk= 50 inches
using Pythagorean theorem,
diagonal length of the trunk=√(height² +length²)
=√(26²+50²)
=√3176
=56.356011 inches
Hence, the length of the diagonal of the trunk is 56.356011 inches.

How many 4-digit numbers divisible by 5, all of the digits of which are even, are there?
Answer:
100
Step-by-step explanation:
If a number is divisible by 5, then the last digit is either 0 or 5.
Since all the digits are even, the last digit must be 0.
There are 4 options for the first digit (2, 4, 6, 8).
There are 5 options for the second digit (0, 2, 4, 6, 8).
There are 5 options for the third digit (0, 2, 4, 6, 8).
So the total number of numbers is:
4×5×5×1 = 100
