Answer:
Out of town teenagers = 30
Step-by-step explanation:
Given that,
Total number of teenagers at a swim meet = 50
Let there are 2x locals and 3x out of town participants. The ratio of locals to out-of-town participants is 2:3.
ATQ,
2x+3x = 50
5x = 50
x = 10
Out of town teenagers = 3x
= 3(10)
= 30
Hence, there are 30 teenagers travelled from out-of-town to the swim meet.
The first one is not proportional and the second one is proportional
The standard equation of an ellipse is:
(x-h)²/a² + (y-k)²/b² = 1
Since the center at the origin, then h = k = 0
The height of this ellipse = 8 units and the width = 4 units, that means the major axis is b (=8) and the minor axis is a (=4)
Then the equation becomes:
x²/16 + y²/64 = 1
Answer: x+5/8 = 1 is the equation where x is the remaining coffee.
Step-by-step explanation:
he drank = 5/8
whole coffee = 1
so
let coffee remaining be x
1-5/8 = x
x+5/8 = 1
Answer:
0.35
Step-by-step explanation:
To start calculating you can divide 20 by 100 to find out the decimal for 1/20, which is equaled to as 0.05, and then times this by the seven to get 0.35
