Answer:
Measure of arc BC = 132°
Step-by-step explanation:
Measure of the central angle COD = 48°
Therefore, measure of arc AB = 48°
Since, segment AC is a diameter and central angle for a diameter is 180°.
Measure of major arc ABC = 180°
measure of arc AB + measure of arc BC = 180°
48° + measure of arc BC = 180°
Measure of arc BC = 180° - 48°
= 132°
Given:
Total number of girls in her class = 16
Total number of boys in her class = 14
To find:
The number of different ways of choosing one girl and one boy.
Solution:
We have,
Total number of girls = 16
Total number of boys = 14
So,
Total number of ways to select one girl from 16 girls = 16
Total number of ways to select one boy from 14 boys = 14
Now, number of different ways of choosing one girl and one boy is
Therefore, the required number of different ways is 224.
Answer:
parallel
Step-by-step explanation:
The "work" is to recognize that both equations describe horizontal lines. All horizontal lines on the Cartesian coordinate grid are parallel.
_____
<em>Additional comment</em>
y = constant . . . . . a horizontal line (y=0 is the x-axis)
x = constant . . . . . a vertical line (x=0 is the y-axis)
__
If you wanted to go to the trouble, you could compare the equation ...
y = constant
to the slope-intercept form ...
y = mx +b
Your comparison would note that m=0. That is, the slope is zero, so the line is horizontal. All lines with the same (zero) slope are parallel.
