Since we need to find the number of ways they could enter first, second and third place, (I can't demonstrate, but you should get the idea) take 8, 7 and 6 and multiply them, 5-1 we don't need, we just need 8, 7, and 6, multiply those three numbers and you get 336, there you go, 336 ways to organize all 8 girls in first, second and third place, hope this helps
I found the corresponding image of the above problem. I also put my answer on the image.
Pls. see attachment.
Answer:it will the take 5 mitutes
Step-by-step explanation:
Let x represent the distance at which both companies charge the same amount.
Let y represent the cost of x miles when using company A.
Let z represent the cost of x miles when using company B.
Company A charges a flat fee of $4 plus $2 per mile. It means that
y = 4 + 2x
Company b does not charge a flat fee but charges $2.80 per mile driven. This means that
z = 2.8x
To determine the distance before both plans will be be the same, we would equate both equations. It becomes.
4 + 2x = 2.8x
2.8x - 2x = 4
0.8x = 4
x = 4/0.8 = 5
So since we know she saved 12% in the previous year so you would make a graph and then draw 100 squares now since 12 dosen't go into 100 evenly you would multiply 12 until you get 96% (which is multiplying 12 by 8) then her salary would be $4,200 dollars multiplied by 8 which is 33,600 dollars then to get your 4 more percent you would divide 12 by 3 which is 4 and you would also divide 4,200 by 3 which is 1,400 and add that to 33,600 dollars and her salary would be 35,000 dollars in the previous year her current year salary would be 38,000 dollars.
