She got 215....but if she would have gotten 10 more, she would have scored 60% of the total marks......so if she got (215 + 10) = 225 she would have scored 60% of the total marks...
so 60% of the total marks = 225
0.60x = 225
x = 225/0.60
x = 375 <===

Answer:
D) 32
Step-by-step explanation:
Given;
series: 56, 54, 50, 38, 34, ....
find the difference between successive numbers;
56 54 50 38 34 x
2 4 12 4 2
The highest difference between the numbers is 12, after which it decreases to 4 and finally back 2.
The next number "x" is calculated as;
34 - 2 = x
34 - 2 = x
32 = x
Therefore, the next number should be 32.
Answer:
Step-by-step explanation:
The rate of change is 2 miles per minute
Step-by-step explanation:
Given
Initial values for rocket
Height = h_1 = 1 mile
Time = t_1 = 30 seconds
As we have to alculate the rate in milea per minute, we will convert the time into minutes
So,
30 secs = 30/60 min = 0.5 min
Final Values:
h_2 = 5 miles
t_2 = 2.5 minutes
Rate of change is given by:
The rate of change is 2 miles per minute
