So if he put them in 2 stacks and there was 1 card left over, he has an odd number of cards
when he put them in 3 stacks there was 1 card left over
we can tell that if he took away one of his card and divided
the stack of cards by two or three the number would be the
same
so he divides it by 4 5 and 6 so the number of cards is not divisible by 2,3,4,5,6
but it is divisable by 7
so we must find a number that when you subtract one you can divide it by 2,3,4,5,6
so i just guessed a term from 7^n
so 49 doesn't work because 48 doesn't divide into 5
343 doesn't work because 342 doesn's divide by 6
but 2401 (7^4) works because 2400 divides evenly by 2,3,4,5, and 6
Just a note, this number is not very logical that he would have time to count them all but hey, it's math
So, let's see, Amber made 3 penalty shots off 4, now, 3 out of 4 is 75% or 3/4. So she's 75% of the time effective.
Lindsay has made 4 out of 6 penalty shots, 4/6 or 2/3, that's about 66% effectiveness.
Li has made 2 out of 3 penalty shots, that's 2/3, that's about the same 66% effectiveness.
so, which fraction is highest 3/4, or 2/3 or 2/3? neverminding the percentages, let's multiply all by the LCD, let's see from 4, and 3, and 3, the LCD is 12.
so, let's multiply all of them by 12, to get rid of the denominator, to see which is highest.
notice, Amber has the higher effectiveness rate, to make it through in the penalty kick.
No.
The first two is okay. Then
Then
4 | 64
8|128
9|144
10|160
Answer:
y=x/2
Step-by-step explanation:
If one line is perpendicular to another, then the product of their slope is -1.
y = –2x+8. This line has a slope of -2. Which means another line must have a slope of 1/2.
By knowing the slope, we then assume this line as x-2y=k. Insert the point in, we find out k=0.
So the equation of this line is x-2y=0, or y=x/2.
50 percent because 10 cars would be 100 percent so 5 cars would be 50 percent you just have to find the half
