The question is on the picture
Vitek1552 [10]

The answer is 4.8873, so you can say over 4 times as great, or almost 5 times as great for the first question.

And I think the second question could be because those over 35 years old have a more stable career, they're more developed skill-wise & worth more to their company so they're paid more, and of higher ranking in their professions, etc.

368 spaces now, why?
There are 22 spaces per row, and we know there are 8 rows, so thats 176 spaces last month,
we add 4 spaces to each row of 22, thats 26 spaces per row, 26 * 8 = 368 total spaces

Answers:

4) r = √[V/(πh)]; d ≈ 5 in

5) 1.25x + 2.50y = 25.00 ; 11 combinations

Step-by-step explanation:

4) (a) Formula for radius

V = πr²h     Divide each side by πh

V/(πh) = r²     Take the square root of each side.

r = √[V/(πh)]

(b) Diameter of tuna can

(i) <em>Data: </em>

V = 66 in³

h = 3.3 in

(ii) <em>Calculations </em>

r = √[V/(πh)]

  = √[66/(π × 3.3)]

  = √(20/π)

  = 2√(5/π)

d = 2r

  = 4√(5/π)

  ≈ 5 in

5) Hot dogs and hamburgers

(a) <em>The equation </em>

Let x = the number of hot dogs

and y = the number of hamburgers

Then

1.25x + 250y + 7 × 0.50 = 28.50

     1.25x + 250y + 3.50 = 28.50     Subtract 3.50 from each side

                1.25x + 2.50y = 25.00

(b) <em>Plot the graph</em>

 Let x = 0. Then

2.50y = 25.00     Divide each side by 2.50

       y = 10

Plot a point at (0, 10).

Let y = 0. Then,

1.25x = 25.00     Divide each side by 1.25

       x = 20

Plot a point at (20, 0).

Draw a straight line between the two points.

Your graph should look like the one below.

(c) <em>Hot dog/hamburger combinations </em>

The possible hot dog/hamburger (x/y) combinations are:

0x + 10y, 2x + 9y, 4x + 8y, 6x + 7y, 8x + 6y, 10x + 5y, 12x + 4y, 14x + 3y, 16x + 2y, 18x + 1y, 20x + 0y

Thus, there are 11 different combinations that Zeke and his friends can buy for $28.50.

It works like this, because one hamburger costs $2,50 and a hamburger half as much.

You can replace one hamburger with two hot dogs (or vice versa) and still spend the  same amount of money,.
