25 in total what do you mean
Answer:
This means it is between 22000000 m and 44000000 m.
Step-by-step explanation:
From the question, the UAE Hope Pobe is between 22 000 km and 44 000 km away from Mars.
Since,
1 000 m = 1 km
Then,
22 000 km = 22 000 x 1000 m
= 22000000 m
also,
44000 km = 44000 x 1000 m
= 44000000 m
Therefore, the Probe is between 22000000 m and 44000000 m.
Answer:
60 students passed, and 75 appeared in examination.
Step-by-step explanation:
Let's say s is the total number of students and p is the number of students who passed.
80% of the students passed, so:
0.8 s = p
If there were 10 less passers, and 15 less students (5 less failures), then the ratio of passers to failures would be 5/1.
(p − 10) / (s − p − 5) = 5 / 1
Simplify the second equation:
p − 10 = 5 (s − p − 5)
p − 10 = 5s − 5p − 25
6p = 5s − 15
Substitute the first equation.
6 (0.8 s) = 5s − 15
4.8 s = 5s − 15
0.2 s = 15
s = 75
p = 0.8 s
p = 60
60 students passed, and 75 appeared in examination.
