Answer:
(x + 1)^2 + (y - 4)^2 = 8
Step-by-step explanation:
Midpoint of the diameter is the centre
So....Centre coordinates are ((-3+1)÷2 ; (2+6)÷2) = (-1;4)
Calculate the radius of the circle....
Radius = square root of [(-1+3)^2 + (4-2)^2]
;Radius = square root of 8
Then substitute the x-coordinate of the centre into the first slot....then the y-coordinate into the second slot and the radius(squared) into last slot of the equation......;
(x + 1)^2 + (y - 4)^2 = 8
Answer:
10.3125 (NOT ROUNDED)
Step-by-step explanation:
1. I changed it to decimals. 1/4 can easily be changed into a decimal.
2. I set 1/4 = x/100. Then cross multiplied. That would give you 4x = 100.
3. Now you would simplify that. x would be 25. So its 25/100 wich then turns to .25.
4. Now you are going to replace them so it would be 1.25 and 8.25.
5. To find out how much milk chocolate there was you would multiply 1.25 and 8.25.
6. That's your final answer
It is easier to do if we get rid of the decimals, so lets multiply both numbers by 10:
5.8/1.2 = 58/12
and reduce the fraction:
= 29/6
then operate:
= 4.83
