4. 5/2
Step-by-step explanation:
Answer:
7:24 pm
Time taken will be longer
Step-by-step explanation:
Given that:
Distance between Manchester and London = 195 miles
Departure time = 3.30 pm
Average speed of Coach = 50 mph
Arrival time in London :
Time taken = distance / speed
Time taken = 195 / 50 = 3.9 hours (3 hours (0.9 * 60) = 3 hours 54 minutes
= 3:30 pm + 3 hours 54 minutes = 7:24 pm
If the speed is Lower then the Timetaken will be longer and subsequently coach will arrive after 7:24 pm
3. ∠1+∠2=180° and ∠2+∠3=180°
4. they are supplementary
5. ∠1+∠2=180°=∠2+∠3
6. ∠1+∠2=180°=∠2+∠3
∠2 are same in both side so ∠1=180°-∠2 =∠3=180°-∠2
7.
Answer:
(-2,3)
Step-by-step explanation:
For the point to be 2/3 of the way; it means it divides AB into the ratio 2 to 1
Now, we can use the internal section formula to get the coordinates of this point
(x,y) = (nx1 + mx2)/(m + n), (ny1 + my2)/(m + n)
where (m,n) = (2,1)
(x1,y1) = (-4,-1)
(x2,y2) = (5,5)
(x,y) = (1(-4) + 2(-1)/(1+2), (1(-1)+2(5)/(1+2)
(x,y) = (-4-2)/3, (-1 + 10)/3
(x,y) = (-2,3)
