Answer:
a : c = 7 : 10
Step-by-step explanation:
The two ratios (a : b and b : c) both have b in common, so to work out what a : c is, we can use b to 'bridge' the two ratios together.
However, in a : b, b is 4. But in b : c, b is 2. We need to make sure b is the same in both ratios before we can combine the ratios together. The easiest way to do this is to multiply b : c by 2 to get b : c = 4 : 10. Now b is 4 in both ratios.
So now, we can combine the two ratios together to get a : b : c = 7 : 4 : 10. Since we only want a : c though, we can just drop the b and get a : c = 7 : 10. No simplifying is necessary since the ratio is already in its simplest form.
Hope that helps! :)
Answer:
0.1
Step-by-step explanation:
In a problem like this the number that is more to the left is greater. As you can see 0.1 is more to the left
It's 4. The factors of 12 are: 1,2,3,4,6,12. The factors of 20 are: 1,2,4,5,10,20.
Answer:
(0,-9)
Step-by-step explanation:
The image of a point over a line is given by the co-ordinate rule:
→
So, when we reflect a point over the line , the x co-ordinate and y co-ordinate change their places.
Here, is . So, from the above rule, after reflection over the line , the image has the following co-ordinates:
Answer:
I would go with c.
