It is 94%. Add everything from 20-21 all the way onwards and divide by 200. Then multiply by 100.
Answer:
1/4( y -2)
Step-by-step explanation:
1/4 y -1/2
Rewriting
1/4 * 1 y - 1/4*2
Factor out the 1/4
1/4( y -2)
Answer:
RT=FE, since this is using SAS (side-angle-side)
Answer:
Length of rear-view mirror = 0.3462 m
Step-by-step explanation:
- As per the attachment first thing we need to calculate is the angle of incidence of light "α" reflected from the rear view mirror to the eyes of the driver.
- As per the diagram the following calculations are:
- α = arctan(half length L of the rear view window / distance between the focus point and the centre of the rear view window).
- half length L of the rear view window = 1.5/2 = 0.75 m
- Distance between the focus point and the center of the rear view window = 0.6+2.0 = 2.6 m
hence,
- α = arctan(0.75/2.6)
- α = 16.091 degrees
Now the we will use α to calculate length of the rear view mirror.
length of the rear view mirror = 2 x 0.6 x tan(α)
length of the rear view mirror = 2 x 0.6 x tan(16.091)
length of the rear view mirror = 0.3462 m
Answer:
x= - 50/9
Step-by-step explanation:
multipy both equations by 12
9x+60=10
then move the constant to the right hand side and change it's sign
9x= 10 - 60
calculate difference
9x = -50
divide both sides by 9
x= - 50/9
