In a table, like the one below, the domain is usually listed in the left column and the range is listed in the right column. You can also refer to the domain as the input values, x, and the range as the output values, y, in a relation or function.
Answer:
we have 10 red marbles and 15 white marbles
Step-by-step explanation:
<u>Step 1:</u> Given data
Total marbles = 25
Ratio red: white = 2:3
<u>Step 2:</u> Write an equation
Red marbles = X
White marbles = Y
X+ Y = 25
X = 2/3 Y
2/3 Y + Y = 25
5/3 Y = 25
Y = 15
X =2/3 * 15 = 10
To control this we can plug this in the equation X + Y = 25
10 + 15 = 25
10/15 = 2/3
This means we have 10 red marbles and 15 white marbles
Answer:
60°
Step-by-step explanation:
Let angle BAE = angle ACD = x
BCD = AEC = 60°
EAC + FCA + ECF + AEC = EAC + x + 60° + 60° = 180°
EAC = 60° - x
BAC = EAC + BAE = 60° - x + x = 60°
First find the side EC by setting up ratio. use pythagorean theorem to find the hypotenuse side.
