To find the ratio of mystery books to the total, divide the number of mystery books by the total number of books and simplify the ratio if possible.
To find the ratio of mystery books to the total, we need to divide the number of mystery books by the total number of books and simplify the ratio if possible.
In this case, the number of mystery books is 12 and the total number of books is 48. So, the ratio of mystery books to the total is 12:48.
We can simplify this ratio by dividing both the numerator and denominator by 12. This gives us a simplified ratio of 1:4.

A. 82 feet
B. 190 feet
C. 226 feet
D. 250 feet
Answer:
Option c is correct
226 feet is the maximum height of the projectile.
Step-by-step explanation:
A quadratic equation , ....[1]
then the axis of symmetry is given by:
As per the statement:
The path of the projectile is modeled using the equation :
....[2]
where, h(t) is the height after t time.
On comparing with [1] we have;
a = -16 and b = 48
then;
sec
Substitute this in [2] we have;
⇒
Simplify:
Therefore, the maximum height of the projectile at 1.5 sec is, 226 feet.
The answer is C on edge

Answer: Option 'C' and 'B' are correct.
Step-by-step explanation:
Since we have given that
In Option 'C' ,
Length of a poster is given by
Width of a poster is given by
So, Area of poster is given by
In option 'B', part of dolls are within the original box is given by
Part of dolls who has charity is given by
Total dolls she donate is given by
On the other hand, In option 'A' has "Division operation" and option 'D' has "Subtraction operation".
Hence, Option 'C' and 'B' are correct.
