Divide the distance by the average speed to find the time. 30 miles 20.04 mph 1.497 hrs. So it would take about 1.5 hours.
Answer: The first one is 7.7. the second one is 7.5 the third one is 7.6 the 4th one is 7.5 the 5th one is 7.7 the 6th one is 7.6
Step-by-step explanation:
Answer: Choice A) x = 15; y = 17
---------------------
Explanation:
The "7x+7" angle and the "112 degree" angle are congruent. They are vertical angles. So
7x+7 = 112
7x+7-7 = 112-7
7x = 105
7x/7 = 105/7
x = 15
We technically have enough to stop here, but let's keep going to find y
The "4y" angle and the "112 degree" angle are supplementary. They form a single straight line. They add to 180 degrees
So,
4y+112 = 180
4y+112-112 = 180-112
4y = 68
4y/4 = 68/4
y = 17
Answer:
CD = 2 units
Step-by-step explanation:
in the given right triangle ΔCDE,
By applying tangent rule,
tan(∠E) = 
= 
tan(30)° = 
CD = 
CD = 2 units
Therefore, CD = 2 unit will be the answer.
