Answer:
20 waves
Step-by-step explanation:
Out of 50 waves, Mark will catch 20 waves. To find this, first, you have to put it into a ratio.
8 x
--- = -----
20 50
To solve this, you need to multiply 8 x 50, which is 400. Next you need to divide 400 by 20, which is 20 waves.
This means x = 20 waves.

x=5
Step-by-step explanation:
x+7=12
x=12-7
x=5
Step-by-step explanation:
The definition of class as per given information is written below;
public class Clock
{
private int hours;
private boolean isTicking;
private Integer diff;
}
The constructor that takes the three variables and then set the values to the instance variables is;
public Clock (int hours, boolean isTicking, int diff)
{
this.hours = hours;
this.isTicking = isTicking;
this.diff = new Integer (diff);
}
0.0009208 you can round it to 0.0009 if you want.
Answer:
- m∠L + m∠M = 90°
- sin(L) = 0.66913
- sin(M) = 0.74314
Step-by-step explanation:
The sum of the two angles is ...
m∠L + m∠M = 42° +48° = 90°
__
A calculator can show you the sines of these angles.
sin(42°) ≈ 0.66913
sin(48°) ≈ 0.74314
_____
The two acute angles of a right triangle always have a sum of 90°.
