The probability that Rachel will win the game is: 1/12
Step-by-step explanation:
The number cubes has six sides numbered between 1 to 6. the chances of each number are equally likely
Let S be the sample space
The sample space has 6*6 = 36 outcomes.
Now, Let A be the event that the sum of numbers on both number cubes is 10
A = {(4,6),(5,5), (6,4)
n(A) = 3
The probability that Rachel will win the game is: 1/12

Rosario's average speed on her way home is 36.66 miles per hour.
<h2><u>

Average speed</u></h2>
Given that each week, Rosario drives to an ice-skating rink that is 60 miles away, and the round-trip takes 2.75 hours, to determine, if she averages 55 miles per hour on his way to the rink, what is her average speed to return to his house, the following calculation must be made:
- 55 = 1
- 60 = X
- 60 / 55 = X
- 1.09 = X
- 2.75 - 1.09 = 1.66
- 55 = 1
- 27.5 = 2
- 55 / 3 x 2 = 36.66
Therefore, Rosario's average speed on her way home is 36.66 miles per hour.

Answer:
Several ways, take the diameter and divide it by half.
Take the circumference "C" and r = C/2π
Step-by-step explanation:
Answer:
504
Step-by-step explanation:
The area of the base is 14 x 14 which is 196
The area of one triangle is 1/2 x base length x height which is:
1/2 x 14 x 11 = 77
So the area of one triangle is 77. The area of all the triangles is the same and there are 4 triangles.
So the surface area is
196 + 77 + 77 + 77 + 77 = 504
That is in standard form already.
Scientific form is 8.24 * 10^-9 answer
