9 out of Reagan's 15 classmates go to bed at 10 p.m.
As a fraction, this would be 9/15.
To convert a fraction to a decimal, you just divide the numerator by the denominator.
Thus, 9 ÷ 15 = 0.6
To turn a decimal into a percentage, you multiply the decimal by 100, and then add a percentage sign.
0.6 * 100 = 60%
Therefore, 60% of Reagan's classmates go to bed at 10 p.m.
Hope this helps!
Answer:
0
Step-by-step explanation:
We can find the slope using the slope formula
m = ( y2-y1)/(x2-x1)
= ( 7-7)/(5-8)
= 0/-3
= 0

Answer:
Step-by-step explanation:
The equation of a parabola in vertex form:
<em>(h, k)</em><em> - vertex</em>
The focus is
We have the vertex (2, -5) and the focus (2, -4).
Calculate the value of <em>a</em> using 
<em>k = -5</em>
<em>add 5 to both sides</em>
<em>multiply both sides by 4</em>
Substitute
to the vertex form of an equation of a parabola:
The standard form:
Convert using
<em>use the distributive property: a(b+c)=ab+ac</em>
