Answer: 45 people
Step-by-step explanation:
Well the ratio of people to minutes for a pool game is 15:13
The ratio for a 39 minute pool game is ?:39
39 is 3 times the amount of 13 so we can assume that ? will be 3 times the amount of 15
15×3=45
So it would take 45 people
Answer:
Step-by-step explanation:
you would solve by grouping the first two terms together and the last two terms together. (x^3+x^2)(+(4x+4)=0. you would factor each one and get x^2(x+1)+ 4(x+1)=0. the final outcome is (x^2+4)(x+1)=0. this is how you find the roots of this equation
sorry if this answer is wrong
I'm not sure how you would not use the slope formula to find the slope from the points?
If you did the slope would be 0
Answer:
![\frac{1}{ - 9}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B%20-%209%7D%20)
Step-by-step explanation:
Exponent rules state that a number to a negative power is equal to one over that number to the number of the negative power (except the power is now positive).
Following this we end up with
![\frac{1}{ { - 3}^{2} }](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B%20%7B%20-%203%7D%5E%7B2%7D%20%7D%20)
Since an exponent only affects the number immediately to its left, the negative sign is not counted when we square 3. 3 squared is 9 so the answer is one over negative 9.
