Since there are a total of 15 shirts,
5 red shirts+4 white shirts= 9 shirts total
3 blue shirts+3 purple shirts= 6 shirts total
<em><u>The odds that you would pick a red shirt and then a white are 3:2</u></em>
3 being the 9 red and white shirts combined.
2 being the 6 purple and blue shirts combined.
9:6 simplified=3:2
9/3=3
6/3=2
3:2
Answer: The odds that you would pick a red shirt then a white shirt would be 3:2 or 60%
We know that:
is an equation of a circle.
When we substitute x and y (from the pairs we have), we'll get a system of equations:
and all we have to do is solve it for a, b and r.
There will be:
From equations (II) and (III) we have:
and from (I) and (II):
Now we can easly calculate a and b:
Finally we calculate
:
And the equation of the circle is:
Im not sureif my answer is correct but 99/18 is 5.5 so if thats an option it might be the answer. its kind of just a guessso im sorry
Answer:
In 10 seconds, the garden hose will emit 15 quarts of water.
Step-by-step explanation:
The amount of water emitted by the garden hose over time can be expressed as a ratio: 9/6, or 9 quarts of water for every 6 seconds of time. We can then simplify this ratio to 3/2, or 3 quarts of water for every 2 seconds of time. Since the ratio will remain constant, or the same, over time, we can set up an equivalent ratio, or fraction to find the amount of water emitted in 10 seconds: 3/2 = x/10. We look at the denominators and see that 2 x 5 = 10. In order to make the ratios equivalent, we would also multiply the numerator by 5: 3 x 5 = 15, which gives us the amount of water emitted in 10 seconds.
