Is it a multiple choice question
Step-by-step explanation:
Answer:
79.2 kilometres per hour
Step-by-step explanation:
1 km = 1000 m
1 hr = 3600 sec. To convert km/hr into m/sec,
We multiply the speed which in this case is 22m/s
by 3.6 giving 79.2 kmh. Therefore 22m/s into kilometer is 79.2 kmh.
Answer:
52.9°
Step-by-step explanation:
step 1
we know that
The total number of successful United States space launches that happened in the years 1957-1995 is equal to

step 2
The numbers of successful United States space launches that happened in the years 1980-1989 is equal to

step 3
The percentage of successful United States space launches that happened in the years 1980-1989 is equal to

step 4
Find out the measure of the central angle you would draw in a circle graph to represent the number of successful United States space launches that happened in the years 1980-1989
we know that
In a circle, 360 degrees represent the 100%
so
using proportion
Find out the measure of the central angle by a percentage of 14.68%
