Answer:
red: 9/20, 0.45, 45%
White: 15%, 0.15, 3/20
Blue: 0.4, 2/5, 40%
Step-by-step explanation:
For red: you start with 9/20. It’s best to get to a denominator of 10. So divide each number by 2. You would get 4.5/10. Then change to a percent by moving the decimal of the numerator one to the right and changing it to percent. 4.5 -> 45. -> 45%. Then for the decimal, divide 45 by 100. 45/100 = 0.45.
For white: you start with 15%. Divide by 100. 15/100=0.15. Put into a fraction with a denominator of 100. It would be 15/100. Simplify. Each number can be divided by 5, so your fraction would be 3/20.
For blue: you start with 0.4. Turn this into a fraction. Since there is one decimal place, it can have a denominator of 10. The fraction is 4/10, simplified to 2/5. Using the fraction 4/10, the percent would be 40%.
I hope this helps!

Answer:
She swims for 3 hours each morning.
Step-by-step explanation:
To determine the number of hours that Kenny swims in the morning, it is necessary to perform the following equation, taking into account that he swims 5 days a week for a total of 30 hours a week, and that in the afternoon he swims for 3 hours:
X + 3 x 5 = 30
X + 3 = 30/5
X = 6 - 3
X = 3
Therefore, Kenny swims for 3 hours in the morning.
Answer:
1 and 7
Step-by-step explanation:
The <em>slope </em>is the number before x. It is identified as m.
Since we know that any variable by itself, without a coefficient, means that there's a 1 in front of it, we can say that 1 is the slope because there's no coefficient shown.
The <em>y-intercept</em> is the number added or subtracted after the slope and x.
Since we have +7 coming after x, we can say that the y-intercept is 7.
