atroni [7]

Answer: A) 4

Step-by-step explanation:

Hi, to answer this, first, we have to calculate the volume of each can:

Volume of a cylinder: π x radius^2 x height

Since:

Diameter: 2 radius

2 = 2r

2/2 =r

r=1

Back with the volume formula:

V = 3.14 ( 1)² 4 =12.54 cubic inches

Now, we have to divide the total volume of soda by the volume of each can:

50.24/12.54= 4 soda cans

Feel free to ask for more if needed or if you did not understand something.

Half of 2/3 is:

$\frac { 1 }{ 2 } \times \frac { 2 }{ 3 } =\frac { 1 }{ 3 }$

This means that 1/3 was left. This also means that they ate 1/3 of the lasagne.

They can be selected in 8! ways

$8! = 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1$

$8! = 40320\ ways$

Two standard 6-sided number cubes are rolled, a red one and a blue one. How many different sums are possible?

AlladinOne [14]

Answer:

There are 11 different sums.

Step-by-step explanation:

When you roll two dice, the smallest number you can get is 2, and the largest 12, and you can get all in between. So 12-2 is equal to 10, but we have to add another 1 because 2 counts. So the answer is 11.
