When you write black to white for the given amount, you write it as 16 to 2

When you reduce that by dividing both numbers by 2, you get 16/2 to 2/2 which is 8 to 1. There is no other answer it could be like 1 to 8 so the answer is Volcanic Grey

The central angle of a minor arc is an acute angle.
Nostrana [21]
<span>The central angle in a minor arc is acute. In a minor arc, the angle must be less than 180˚. However, it doesn't have to be less than 90˚. So the central angle is sometimes acute. 

hope this helps u leave a like if it does</span>

On a certain hot​ summer's day, 643 people used the public swimming pool. The daily prices are $1.50 for children and $2.00 for
lilavasa [31]

249 children and 394 adults swam at the public pool.

Step-by-step explanation:

Number of people swam at pool = 643

Receipts = $1161.50

Cost for one child = $1.50

Cost for one adult = $2.00

Let,

x be the number of children

y be the number of adults

According to given statement;

x+y=643    Eqn 1

1.50x+2.00y = 1161.50   Eqn 2

Multiplying Eqn 1 by 2

2(x+y=643)\\2x+2y=1286\ \ \ Eqn\ 3\\

Subtracting Eqn 2 from Eqn 3

(2x+2y)-(1.50x+2.00y)=1286-1161.50\\2x+2y-1.50x-2.00y=124.50\\0.5x=124.50

Dividing both sides by 0.5

\frac{0.5x}{0.5}=\frac{124.50}{0.5}\\x=249

Putting x=249 in Eqn 1

249+y=643\\y=643-249\\y=394

249 children and 394 adults swam at the public pool.

Question is in picture above.
creativ13 [48]
I think that answer is B there is a association of greater growth occurring outside the lagoon because mainly the numbers each time get bigger like the first time it is 20 and then it is 31 so it goes up 11 more and then the third time it is 34 and it goes up 3 and then the last one sadly drops to 21.
