<span>Each ticket costs $10. He bought "x" tickets. Ticket cost = 10*x
Each bag of popcorn costs $5.
He bought "y" bags of popcorn.
Popcorn cost = 5*y Service fee: $3
Total cost = 10x + 5y + 3 <= $75 is the inequality.
10x + 5y <= 72
If x = 4,
then 40 + 5y <= 72
5y <= 32
y <= 6.4
So y = 6 bags of popcorn.</span>

Josiah can buy 6 more popcorn bags. 

The solution is as follows:
10x + 5y + 3 ≤ 75

if x = 4, the inequality will look like this:
10(4) + 5y + 3 ≤ 75
43 +5y ≤ 75
5y ≤ 32
y ≤ 6.4 or <span>6

The volume of the figure below is 496.21 ft^3<br> True or False
timofeeve [1]

Answer:

First option: True.

Step-by-step explanation:

To know if the volume of this cylinder is 496.21 ft³, you need to use the formula for calculate the volume of a cylinder:

V=\pi r^2h

Where "r" is the radius and "h" is the height.

You can observe in the figure that the radius of the cylinder is 4.5 feet and the height is 7.8 feet.

Then, knowing this, you can substitute these values into the formula.

Therefore, the volume of this cylinder is:

V=\pi (4.5ft)^2(7.8ft)\\V=496.21ft^3

Then the answer is: True.

Y=-2x-3,y=-2x+2 how many solutions does the system have
denis23 [38]

Answer:

3x + 3 = -2x + 3

3x + 2x = 3 - 3

5x = 0

x =0.

So y = 3(0) + 3 = 3.

Piecewise functions have different definitions, depending on when you evaluate them.

Given an input x, your function returns:

  • 2x if the input is negative
  • 1 if the input lies between 0 (included) and 2 (excluded)
  • the square root of x if the input is greater than 2 (included)

You want to know what f(0) is. In other words, you want to know what happens if we give 0 as input.

The piecewise definition tells us that, if the input is 0, the function outputs 1.

So, you have f(0) = 1.
