Answer:
$269.50
Step-by-step explanation:
Between 42-49
So, you have to assume 49 students will arrive, better to have more and have left overs than get less and not find kids.
As for math you just do 49 x 5.50 = 269.5
Finally that measn the budget for the food is $269.50
Answer:
9
Step-by-step explanation:
Since we know the number of contestants in Round 2, we could go step by step and calculate the number of remaining contestants in Round 3, then Round 4 and finally Round 5.
However, we can do it without calculating. So in Round 3, there will be:
R3 = R2^((n-1)/n), where n is number of the round
R3 = R2^(2/3)
For Round 4, the number will be:
R4 = (R2^(2/3))^(3/4)
And Round 5 will be:
R5 = ((R2^(2/3))^(3/4))^(4/5)
Threes and fives in exponents will cancel out and we'll remain only with:
R5 = R2^(2/5)
R5 = 249^(2/5)
R5 = 9.08
Rounded to the nearest integer, the number of contestants in Round 5 is 9.
Answer:
x=5, y=1. (5, 1).
Step-by-step explanation:
6x+4y=34
3x-y=14
---------------
y=3x-14
6x+4(3x-14)=34
6x+12x-56=34
18x=34+56
18x=90
x=90/18
x=5
3(5)-y=14
15-y=14
y=15-14
y=1
