You want to take 837 out of 36.
you can get 837 out of 3 0 times so you tack on the 6(0)
you get 837 out of 36 0 times so you tack on a zero(00)
Because you are adding a 0, you are now creating a decimal
you get 837 out of 360 0 times so you tack on a 0 (00.0)
You get 837 out of 3600 4 times so you put the 4 after the 0s (00.04)
Now you multiply 4 and 837 to get 3,348 and take that away from 3600 to get 252
Not you tack on a 0.
You get 837 out of 2520 3 times so you tack the 3 on behind the 4. (0.043)
Because of significant digits, your answer is 0.043
First, we need to convert all the fractions to have the same denominator. 10 and 25 are both multiples of 100, so 100 would be appropriate.
Sam has a 7/25 chance. Because we want ?/100, something needs to change. To get from 25 to 100, you need to times 25 by 4, right? So, do the same with the 7.
7 x 4 = 28. Therefore Sam has a 28/100 chance.
Sue has 3/10. Using the same method, we can see that 3 needs to be multiplied by 10 (because 10 times 10 = 100). So Sue has a 30/100 chance.
Tom is already in the fraction we like, so just keep this as 21/100.
Now, add 28/100, 30/100 and 21/100 to get 79/100.
Because won of them will get the role of class president, we know that the probability adds to 1. To get a full probability (100/100, or 1), what needs to be added to 79/100?
Another way of going about this is 100/100-79/100. The answer is 21/100
The probability of Liz winning is 21/100.
Let me know if this is still unclear, I would be more than happy to explain in more detail if necessary :)
Answer:
umm i think you would be at tje point 4,0
First, you want to establish your equations.
L=7W-2
P=60
This is what we already know. To find the width, we have to plug in what we know into P=2(L+W), our equation to find perimeter.
60=2(7W-2+W)
Now that we only have 1 variable, we can solve.
First, distribute the 2.
60=14W-4+2W
Next, combine like terms.
60=16W-4
Then, add four to both sides.
64=16W
Lastly, divide both sides by 16
W=4
To find the length, we plug in our width.
7W-2
7(4)-2
28-2
L=26
Answer= 8/125 or 0.016
16/1000 can be simplified by dividing both the numerator and denominator by 8
16 2
____=___
1000 125
2/125=0.016
