Answer:

29.39

Step-by-step explanation:

So, the formula for circumference is 2(3.14)r.

If the question is looking for the diameter,

You don't have to include the r, you can just do d(3.14)=92.31

You can divide 92.31 by 3.14 and you get 29.39

Step-by-step explanation:

$240 for 12 t-shirts.

that means 240/12 = $20 per shirt.

therefore, only the second option (with $100, $200, $300, $400) is correct. when adding 5 shirts, the price goes up 5×$20 = $100.

all the other options use a different unit price.

The missing values are 9 miles, 6 inches, 30 miles, and 30 miles, respectively.

It's a math tool for solving problems about proportion. You can relate more than 2 variables and from the proportion, it's possible to find an unknown number.

1/2 in= 1 mile, from the rule of three, you can find the distance in miles.

                        1/2 inch ------------- 1 mile

                        4.5 inches --------- x miles

Applying cross multiplication

1/2x=4.5

x=4.5 *2

x=9 miles

1 in= 5 miles, from the rule of three, you can find the distance in miles.

                        1 inch ------------- 5 miles

                        x inches --------- 30 miles

Applying cross multiplication

5x=30

x=6 inches

1 in= 10 miles, from the rule of three, you can find the distance in miles.

                        1 inch ------------- 10 miles

                        3 inches --------- x miles

Applying cross multiplication

x=3*10 miles

x=30 miles

1 in= 15 miles, from the rule of three, you can find the distance in miles.

                        1 inch ------------- 15miles

                        2 inches --------- x miles

Applying cross multiplication

x=2*15 miles

x=30 miles

The lunch menu is an illustration of permutation and combination

To answer this question, the following set of lunch menu would be used:

Since the event organizers can repeat lunch menu, then each of the 5 lunch menus can be selected each of the 3 times.

So, the number of selection is:

n = 5³

Evaluate

n = 125

Possible selections are:

Since the event organizers cannot repeat lunch menu, then each of the 5 lunch menus can be selected once of the 3 times.

Answer:

Step-by-step explanation:

Given the equation: y = 8 * 2ˣ, substitute the x-values in the table for x in your equation, to find the y-values.

For x = -1

     The surface area is found by finding the area of all shapes creating the surface, and then adding them together.

Example:

     If we have a 5 x 5 x 5 cube, we will find all six sides. Since 5 x 5 is 25, and 25 x 6 = 150, the surface area of this example cube will be 150 units².

     Why the x 6? Since it is a cube all the sides have the same area, and a cube has 6 sides.

Answer:

46.24 mm²

Step-by-step explanation:

Given:

s = 6.8 mm

To find the area of the square, simply square the measure of the side length.

⇒ Area of polygon = s²

Substitute the measure of the side length:

⇒ Area of polygon = (6.8)²                                                              [s = 6.8 mm]

Simplify the area:

⇒ Area of polygon = (6.8)(6.8)

⇒ Area of polygon = 46.24 mm²

Answer:

46.24mm.²

Step-by-step explanation:

Multiplying base by height:

6.8 times 6.8 = 46.24mm.²

Or doing 6.8² (same thing)

Since this is a square you can do 6.8 squared.
