A lake initially contains 3000 fish. Suppose that in the absence of predators or other causes of removal, the fish population in

katrin [286]

Let x = number of months.

Let y = total number of fish in pond.

6% of 3,000 = 180 fish

We can use an equation to help us with this problem.

y = 3,000 + 180x - 400x. Combine like terms.

y = 3,000 - 220x. Plug 9 in for x.

y = 3,000 - 220(9). Solve for y

y = 1,020.

There are 1,020 fish in the pond after 9 months.

You lose track of how many 2-point baskets and 3-point baskets a team makes in a basketball game. The team misses all the 1-poin

babunello [35]

Answer:

x-intercept: 27, the number of 2-pointers if no 3-pointers
y-intercept: 18, the number of 3-pointers if no 2-pointers

Step-by-step explanation:

Each intercept is found by setting the other variable to zero and solving for the variable value of interest.

2x +3y = 54

<u>x-intercept:</u>

2x = 54

x = 27

<u>y-intercept:</u>

3y = 54

y = 18

__

By definition, the intercept values are the values that satisfy the equation when the other variable is zero.

x-intercept: To score 54 points, the team would have to make 27 2-point baskets if no 3-point baskets were made.

y-intercept: To score 54 points, the team would have to make 18 3-point baskets if no 2-point baskets were made.

Find the amount of empty space within a cylinder containing three solid spheres, where each sphere has a radius of 3 cm. (Volume

Nadya [2.5K]

Answer:

Ves = 169.56 cm³

Step-by-step explanation:

Let call Vc volume of cylinder

If the cylinder has to contain three spheres of radius 3 cm the height of the

cylinder is 3 * 2 * 3 = 18 cm ( we have three diameters )

The radius of the base of the cylinder is 3 cm

And Vc = π*r²*h ⇒ Vc = (3,14) * 9 * 18 ⇒ Vc = 508.68 cm³

On the other hand we have Vs (volume of one sphere)

Vs = 4/3 * π * r³ ⇒ Vs = 4/3 * 3,14 * (3)³ ⇒ Vs = 113,04 cm³

as we have 3 spheres the total volume is 3 * 113.04

Vts = (total volume of spheres) = 339,12 cm³

The empty space withing the cylinder is the difference between Vc and Vts

Ves ( volume of empty space ) = Vc - Vts = 508.68 - 339,12

Ves = 169.56 cm³
