The radius is 3
center is (-3,3)
Step-by-step explanation:
start at (0,0) go left 3 then up 3 put a point there. Then from that point go up, left, right, and down 3. It should be a circle.
Answer:
umm I think we need more information because it just like your giving us that but we don't know what to do with it.
notice above... we use the decimal format for the percentage, thus 20% is really just 20/100, 40% is 40/100 and so on.
so.. whatever "x" and "y" amounts are, we know they have to add up to 60 Liters, that is x+y = 60
and whatever the concentration amount of each is, it must add up to (60)(0.40), that is 0.20x+0.50y=(60)(0.40)
thus
solve for "x", to see how much of the 20% solution will be needed
what about "y"? well, y = 60 - x
To solve this you need to make all of the percentages for the scores go back 2 decimals. For example: 82 --> 0.82
Next you multiply the decimal by the percent on the test.
0.90 × 75 = 67.5
0.95 × 10 = 9.5
0.82 × 15 = 12.3
Finally you add all of them up and get an answer.
67.5 + 9.5 + 12.3 = 89.3
