Answer:
134 kilometers or 83 miles.
Explanation:
First make all the units equivalent, so
60 km/h = 60 km/h or 37.28 m/h
45 m/h = 72.42 km/h or 45 m/h
50 km/h = 50 km/h or 31.07
So in one hour the car has gone 60 km or 37.28 m because they travel at 60km/h, which means they get that far in that amount of time.
In half an hour they get half of 45 miles, because 45 m/h means they get 45 miles in 60 minutes, so in 30 minutes, or half and hour, they are getting half of 45 = 22.5 miles or 36.21 kilometers.
In 45 minutes they are getting 75% of 50 km because 45 minutes is 75% of an hour. So 75% of 50 is 37.5 km or 23.3 miles.
Add this all together and get:
Kilometers:
60 + 36.21 + 37.5 = 133.71 km
Miles:
37.28 + 22.5 + 23.3 = 83.08 m
133.71 km = 83.08 So it checks out.
This is approximately 134 km or 83 miles.
The simplest form for 0.41 is 41/100. 41 and 100 do not have common factors so they cannot be simplified.
X will stand for every extra book sold
880 = 4x + 500
subtract 500 from both sides
380 = 4x
divide both sides by 4
x = 95
they sold 95 books
Answer:
105
Step-by-step explanation:
t = 0
frame = 190
so it means, the video has 190 before the timer start counting
speed 25 fps
-------
t = -3 2/5 s = -17/5 s
frame = ?
with the rate of 25 fps
it gain 25 x -17/5 = 85 frame.
so the video at that time has already played
190-85 = 105 frame
Answer:
Complementary angles are those that sum up to 90o.Vertical angles have equal measures. Therefore, if vertical angles measure 45o each, they are complementary.
Explanation: Here how it might look if angles ∠1 and ∠3 are measured at 45o.
