Answer:
B) 
Step-by-step explanation:

I am joyous to assist you at any time.
First you need to c<span>onvert the given percentage into fraction by dividing it by 100 and removing percentage symbol (%).
Then you reduce the fraction into simplest forms.
Finally you write the </span> fraction turned simplest form to a ratio by writing
the numerator first,then the denominator.
Example:50%=


.
=1:2
Tony : d = 108m.....so Tony walks 108 meters per minute
Mark :
(10,1100),(20,2200)
slope = (2200 - 1100) / (20 - 10) = 1100/10 = 110 meters per minute
So Tony's walk speed is 2 meters per minute slower then Tony's walk speed
Answer:
x = 29°
Step-by-step explanation:
the Δ on the right has 3 angles whose measures are 30°, 74°, and 76° (you get 76° because it forms a linear pair with an angle that is 104°; you get 74° by adding 30 and 76 and subtracting the sum from 180°.
the Δ on the left has 3 angles whose measures are 45°, 29°, and 106° (you get 106° because it forms a linear pair with an angle that is 74°; you get 29° by adding 45 and 106 and subtracting the sum from 180°.
∡x is a vertical angle with the angle that measures 29° and vertical angles are congruent
