Answer:
The answer is 91
Step-by-step explanation:
90 x 6 = 540
The numbers need to equal 540 all together to make an average of 90.
97 + 86 + 83 + 95 + 88 = 449
540 - 449 = 91
To check:
97 + 86 + 83 + 95 + 88 + 91 = 540
Therefore, the answer is 91

Correct choice is E
Answer:
a) The center coordinates O is (0,0)
b) The radius C = 15
Step-by-step explanation:
The given equation of the circle is : ![x^{2} + y^{2} = 225](https://tex.z-dn.net/?f=x%5E%7B2%7D%20%20%2B%20%20y%5E%7B2%7D%20%20%3D%20225)
Now, general form of the equation of the circle is:
![(x-h)^{2} + (y - k)^{2} = r^{2}](https://tex.z-dn.net/?f=%28x-h%29%5E%7B2%7D%20%20%2B%20%28y%20-%20k%29%5E%7B2%7D%20%20%20%3D%20r%5E%7B2%7D)
where (h,k) are the center co -ordinates and r is the radius of the circle.
Comparing the general equation with the given equation, we get
![(x-0)^{2} + (y - 0)^{2} = (15)^{2}](https://tex.z-dn.net/?f=%28x-0%29%5E%7B2%7D%20%20%2B%20%28y%20-%200%29%5E%7B2%7D%20%20%20%3D%20%2815%29%5E%7B2%7D)
So, here the center coordinates (h,k) = (0,0)
And the radius of the given circle is r = 15
These girls really need to get their cookie situation organized!
Alright, so... first let's get this problem into a simpler form.
They made 3/5 of the total, then 2 dozen which = 24 and they still have to make 1/3 more.
So to make 3/5 and 1/3 more compatible, find the LCM of the Denominator. This = 15. 5*3=15 so take 3 (from 3/5) and multiply by 3, which is 9.
This turns 3/5 to 9/15
Then do the same to the other fraction. The Denominator (3) x 5 = 15, so take the Numerator (1)x5= 5.
This turns 1/3 to 5/15
Now that this is a little more clear, let's look at the problem with our equal and substituted values.
They made 9/15 of the total, then 2 dozen which = 24 and they still have to make 5/15 more.
So from this, we can see that after they made 24 (2 Dozen) that they need 5/15 more. 15/15 would mean they're done, so that minus 5/15 = 10/15.
The difference from 9/15 & 10/15 is 1/15. This is how much was added when they made 24 more. So now we know that 1/15=24.
With this information, we can finally solve the problem.
They plan to bake 15/15 of the cookies. This is just a term that is equal to 1 whole. The "whole" is the whole amount of cookies being baked. Since 1/15=24, we can figure out 15/15 by taking 15x24.
15 x 24 = 360. So they made 360 cookies. Sounds delicious.
I hope this helped! And hopefully these imaginary friends sell all 360 cookies!
