6+3+5+7= 21 balls total
Choose 2 balls
21C2= 210 total number of ways you could have chosen the two balls
(nCr- n=total, r=choose)
Total green balls= 3
You choose first green ball out of 3
3C1
Then you choose second green ball out of the 2 green balls left
2C1
Multiply these two outcomes
3C1•2C1= 6
Probability=
6/210= 1/35
Answer:
85 ft^2
Step-by-step explanation:
Let us calculate the area of the triangles and the base.
For the triangles, we can use the area formula and get 5 • 3 which is 15. Since there are 4, we multiply it by 4 and get 60.
For the base, we have 5 • 5, which is 25. Adding it together, we get 85.
If you are stuck on how to find surface area, all you have to do is find the area of each side and add.
I hoped this helped!
Answer:
c is the right answer for the problem
Answer:
n=-11
Step-by-step explanation:
Since -15 is 4 less than -11, it would be -11.

Answer:
Victor gives 28 tools to IIya.
Step-by-step explanation:
Consider the provided information
The ratio of the number of Victor’s tools to the number of Ilya’s tools is 5:2
Let V represents the Victor and I represent llya
Therefore,

It is given that Victor has 42 more tools than Ilya.

Solve the above equation.




Thus, IIya has 28 tools.
Victor has 42 more tools than Ilya. Therefore 42 + 28 = 70.
Victor has 70 tools.
We want to find the number of tools victor needs to give to IIya so that the ratio of the number of Victor's tools to the number of Ilya’s tools will be 3:4
Let Victor gives x tools to IIya. Thus,





Hence, Victor gives 28 tools to IIya.
