It’s number 12!!!!! I know it already got answered

subtract the numbers:


subtract 9 from both sides

simplify

divide both sides by 6


decimal

Hope this helps :)
Zane climb up in 33 seconds
44•33 = 1452 m.
so, Zane start from 1313 + 1452 = 2765 m below the edge.
to reach the edge with constant speed, Zane need 2765/44 = 62.84 seconds
we can round it to 63 seconds
Question 4
The magnitude;
Using Pythagoras theorem,
(-200)² + (-530)² = 320900
Length = √320900
= 566.5 mi
To get the angle
Tan θ = opposite/adjacent
= 200/530
= 0.3774
θ = tan^-1 (0.3774)
= 20.67
≈ 21°
The direction from the Cartesian plane is south of west.
Therefore, the magnitude and the direction will be;
About 566.5 mi, 21° south of west
Question 5.
To get the resultant of two vectors we just add the two vectors given.
This involves adding the corresponding values.
Thus, for <-6,5> and <6,-5>
Resultant vector = <(-6+6),(5+-5>
= <0,0>
Answer:
4:3
Step-by-step explanation:
He has 4 Soccer Medals, 3 Swimming Medals
So it would be 4:3
