Answer:
7 to 3 is this answer
Step-by-step explanation:
if you noticed, with all the other ones they all have 3 : 7 in it. So by the process of elimination it's 7 to 3 that is different. I'll tell you why,
3 : 7, that is the ratio we have as an example. That's why it isn't the different one.
3 to 7, you say 3 : 7 as 3 to 7 to it still has the same ratio
3/7, this is how to type the fraction version of the ratio so it makes sense that it is the same one as 3 : 7.
7 to 3, if you haven't noticed yet, all of them has 3 : 7 as a counterpart. They are all the same but this one, this is 7 : 3 or 7 to 3. So with logic, this is the different ratio.
Slope is 2/-1 or -2. Because you go up twice and then you go left once.
The correct answer is: [B]: " y = 9 " .

Answer:
For right angle triangle,
we use Pythagoras theorem that is:
c = 
For question 1:
c = ?
a = 40
b = 9
putting them in formula,
c = 
c = 41
For question 2:
c = ?
a = 12
b = 13
putting them in formula,
c = 
c = approximately 17.69181
For question 3:
c = 35
a = 20
b = ?
putting them in formula,
1225 = 400 + 
= 1225 - 400
= 825
b = 5 
For question 4:
c = 37
a = 20
b = ?
putting them in formula,
1369 = 400 +
= 1369 - 400
= 969
Taking square root on both sides
b = 31.12
Hope it helps.
