Answer:

I do not know, but I do know the formula.

The formula is: 12pl+B where p represents the perimeter of the base, l the slant height and B the area of the base.

The top 3 triangles are the same and the area for a triangle is 1/2 base*height so 3(1/2*6.1*12.2)+(1/2*6.1*5.3)=127.795
Or about 128

Ok if half are female that means 40 than 80 more for each of them because they all produce 80 so 80 times 40 = 3200 your gonna do the same 2 more times because of 3 generations so 3200 times 3 = 9600 in total

Pls answer with explanation!

Answer:

3,750 cars.

Step-by-step explanation:

We are given that the equation:

$y=9000-2.4x$

Models the relationsip between y, the number of unfilled seats in the stadium, and x, the number of cars in the parking lot.

We want to determine the number of cars in the parking lot when there are no unfilled seats in the stadium.

When there are no unfilled seats in the stadium, y = 0. Thus:

$0=9000-2.4x$

Solve for x. Subtract 9000 from both sides:

$-2.4x=-9000$

Divide both sides by -2.4:

$x=3750$

So, there will be 3,750 cars in the parking lot when there are no unfilled seats in the stadium.
