Answer:
Alice: 20 coins, Ben: 16 coins, and Carlos: 4 coins.
Step-by-step explanation:
We know that the dive results in 40 gold coins.
We know that:
Alice: $7,600 Ben: $5,900 Carlos: $1,400.
So they have $ 14900 in total.
Now we will divide that money by 40.
So 1 gold coin costs $ 372.5. Now we will calculate how much they can get for the money they have.
We conclude that:
Alice: 20 coins, Ben: 16 coins, and Carlos: 4 coins.
The solution of the given equation is (3,6). The correct option is B.(3,6)
<h3>Given equations,</h3>putting the value of y from equation (1) in equation (2) , we get
substitute the value of x=3 in equation (1) we get,
Hence, the solution of given equation is (3,6).
So, the correct option is B.

Answer:
Step-by-step explanation:
To solve this problem we need to be familiar with the formula for the surface area of a cone:
We are given the length of a side and the diameter, to calculate the radius divide the diameter in half:
To calculate the height of the cone, we must use the Pythagorean Theorem:
We can treat the side length as the hypotenuse , the radius as the base
, and solve for height
. Set the expression up like this:
Now we can plug into our original formula:
