Part A :
D = (1/4) * C D = 1/4 * 24 D = 24/4 = 6 ft above sea level
Part B :
Your answer is positive because D is still above sea level...if it would have been below sea level, then it would have been negative
Answer:
The point-slope formula states:
(

=
m
(
x

)
Where
m
is the slope and
(
x

y

)
is a point the line passes through.
Substituting the slope and values from the point in the problem gives:
(
y

If you want the equation in the somewhat more familiar slope-intercept form we can solve this equation for
y
. The slope-intercept form of a linear equation is:
y
=
m
x
+
b
Where
m
is the slope and
b
is the y-intercept value.

Step-by-step explanation:
Answer:
c) $615
Step-by-step explanation:
The expression used to determine how much is the charge for the customer after the job is
where
h is the number of hours the job took
c is the number of cans of paint used during the job
In this problem:
c = 3 (the painter used 3 cans of paint)
h = 15 (the painter took 15 hours for the job)
So substituting these values into the equation for p, we find the total value that the painter charged for the job:
So, the correct answer is
c) $615
Answer:
Midpoint of a segment in the complex plane with endpoints at 6 -2i and -4 + 6i is:
1+2i
Step-by-step explanation:
The midpoint of a segment in the complex plane with endpoints at 6 -2i and -4 + 6i is:
Hence, midpoint of a segment in the complex plane with endpoints at 6 -2i and -4 + 6i is:
1+2i
Answer:
26 pencils were thrown away.
Step-by-step explanation:
1/5 = 8/40
1/4 = 6/32
add them together 18/40
26 were thrown out
