40/2=20 half is as many their is if she has lest of seven round to the highest num because they are all even numbers
You can do this by completing the square
x^2 - 14x + y^2 + 8 = 16
(x - 7)^2 - 49 + (y + 4)^2 - 16 = 16
(x - 7)^2 + (y + 4)^2 = 16 + 16 + 49 = 81
so the center is at (7 , -4) and radius = sqrt81 = 9
Answer:
For blue its 3/12 = 1/4 = 25%
For red it's 6/12= 1/2= 50%
For green 2/12= 1/6= 17%
For black 1/12= 8%
Step-by-step explanation:
All you have to do is add up all the marbles 3 + 6 + 2 + 1 = 12 and then you put the number of marbles for each color and divide it by 12 which gives you those percentages. I don't know if you wanted the answers in percentages or fractions so I gave you both . Good luck!!
Answer:
0.11
Step-by-step explanation:
You would convert the percentage to a fraction. Since the % symbol means 'out of 100', you would put 11 over 100: 11/100.
Then you would convert the fraction to a decimal: 0.11.
An easier way could also be to take the percentage and move it two decimal places to the right.
Ex: 43% moved two decimal places to the right would be 0.43.
I hope this helps!
First, solve the inequality:
![7(4x - 1 ) + 6x \ \textgreater \ -279\\ 28x-7+6x\ \textgreater \ -279\\ 34x\ \textgreater \ -272\\ x\ \textgreater \ -8](https://tex.z-dn.net/?f=7%284x%20-%201%20%29%20%2B%206x%20%5C%20%5Ctextgreater%20%5C%20%20-279%5C%5C%0A28x-7%2B6x%5C%20%5Ctextgreater%20%5C%20-279%5C%5C%0A34x%5C%20%5Ctextgreater%20%5C%20-272%5C%5C%0Ax%5C%20%5Ctextgreater%20%5C%20-8)
Since x is <u>greater than</u> -8, you have the arrow point up the graph towards the positive side starting at -8.
Since it's greater than but not equal to -8, the circle is open.
Thus your graph is
