davit drives 16.5 miles in 10 minutes.
he passes a sign which gives the speed limit as 65 mph.
by how much, in mph, did davit's average speed exceed the speed limit?

34 mph

Step-by-step explanation:

Davit's average speed in miles per minute

= 16.5/10

= 1.65 miles per minute

Davit's average speed in miles per hour

= 1.65 × 60 (Since there are 60 minutes in 1 hour)

= 99 mph

Difference = 99 - 65

= 34 mph

c 1 hour

step-by-step explanation:

m = 2e

m = 2 so 2 = 2e

1 = e

m∠cdf = 43° , m∠gdf = 114°, m∠gde = 23°, m∠edh = 23° , m∠cdh = 157°

step-by-step explanation:

since, it is given that de bisects the angle gdh ⇒ de divides the angle gdh into two equal angles.

⇒ m∠gde = m∠edh

⇒ 8·x   - 1 = 6·x + 5

⇒ x = 3

so, m∠gde = 8·x - 1 = 23°

and m∠edh = 23°

now, it is given ∠cde is an straight angle so, m∠cde = 180°

⇒ m∠cdf + m∠fdg + m∠gde = 180°

⇒ 43° + m∠fdg + 23° = 180°

⇒ m∠fdg = 114°

again, m∠cde = m∠cdh + m∠edh = 180°

m∠cdh + 23° = 180°

⇒ m∠cdh = 157°
