Answer:
The diameter is 14
Step-by-step explanation:
The area of a circle is given by
A = pi r^2
We know the area is 49 pi
49 pi = pi r^2
Divide each side by pi
49 pi/ pi = pi r^2/pi
49 = r^2
Take the square root of each side
sqrt(49) = sqrt(r^2)
7 =r
We want the diameter
d = 2r
d = 2*7
d = 14
-85, -87, -89
Step-by-step explanation:
1. Divide -261 by 3. (Answer is -87)
2. Take the odd integer before it (-85) and the odd integer after it (-89).
Answer: 7x+y+8
Step-by-step explanation:
Combining like terms is just like what it sounds. You take the like terms, or terms that have the same variables and such, and add them together.
For this problem, we can see that 12x and -5x are like terms because they both consist of a numerical coefficient and the variable x.
We can see that -3y and 4y are like terms because they both have a numerical coefficient and y for variable.
Now, we can combine like terms.
12x-3y+8-5x+4y [combine like terms]
7x+y+8

Answer:
1.042% of the total tickets sold 1 child ticket.
Step-by-step explanation:
As given,
A Water park sold 72 child tickets and 24 adult tickets.
So,
The total number of ticket sold by a Water park = Total child ticket sold + Total adult ticket sold
⇒The total number of ticket sold by a Water park = 72 + 24 = 96
Now,
The total child ticket sold = 
×100% = 0.75×100% = 75%
Now, we get
72 child ticket sold % = 75
⇒ 1 child ticket sold % = 
= 1.042%
So, we get
1.042% of the total tickets sold 1 child ticket.
