Answer:
x = 5√3
Step-by-step explanation:
From SOHCAHTOA you might recall that sin x = opposite/hypotenuse
So sin 60° = x/10
sin 60° = 0.5 √3
so x = 10*0.5√3 = 5√3
Answer:
The quantities are not proportional.
Step-by-step explanation:
The values, x and y, do not begin or pass through the origin, (0,0). This means they are not proportional.
Answer:
Option D
Step-by-step explanation:
Slope intercept is:

m - slope
b - y-intercept.
The slope in the question is -12. The y-intercept is 1/2.
Plug in the values:

Hope this helps.
This question is simply conversions
we know there are 100 cm in a m so..
50 × 100 = 5,000 cm/s
and we know there are 1,000 m in a know so..
50 ÷ 1,000 = 50/1,000 = 1/20 km/s
