Answer:
40mm=4cm
diameter=radius×2=4×2=8cm
45% of some number x is 810.
We can rewrite this as
![x\cdot0.45=810](https://tex.z-dn.net/?f=x%5Ccdot0.45%3D810)
And solve for x
![x=\dfrac{810}{0.45}=1800](https://tex.z-dn.net/?f=x%3D%5Cdfrac%7B810%7D%7B0.45%7D%3D1800)
He had $1800 before he had bought new TV.
The range of the video games owned for the cluster is between 8 to 10.
Given
A group of children 6 to 10 years old were asked how many video games they owned.
The scatter plot shows the results.
<h3>What is the range?</h3>
The range is the difference between the lowest and highest numbers in a data set.
The range of video games owned for the cluster is 8 to 10.
Therefore,
The range of the video games owned for the cluster is;
![\rm Range = Highest \ value - lowest \ value\\\\Range=10-8\\\\Range=2](https://tex.z-dn.net/?f=%5Crm%20Range%20%3D%20Highest%20%5C%20value%20-%20lowest%20%5C%20value%5C%5C%5C%5CRange%3D10-8%5C%5C%5C%5CRange%3D2)
Hence, the range of the video games owned for the cluster is between 8 to 10.

A.
This is because we start with the slope of 6. This is because it is the slope of the original equation (the number attached to x) and parallel lines have the same slope. Then you can use that along with the point to find the y intercept using slope intercept form (y = mx + b)
y = mx + b
10 = 6(4) + b
10 = 24 + b
-14 = b
So -24 must be the number at the end of the equation, making a the right answer.
