a.70(h + 2)
b.70(h - 2)
c.70h
Answer:
70(h-2) is the correct answer
Answer:
slope of the line perpendicular to MN = 2/3
Step-by-step explanation:
slope = y2 - y1 / x2 - x1
the given co-ordinates are:
x1, y1 = -3, 4
x2, y2 = 5, -8
slope = -8 - 4 / 5 + 3
= -12/8
= -3/2
slope of the line perpendicular to MN = -1 / slope
= -1 / -3/2
= -1 * -2/3 = 2/3
Answer:
m = 2/3
Step-by-step explanation:
Slope = (y-y)/(x-x)
(-8-4)/5- -3) = -12/8
-12/8 = -3/2
Slope od the perpendicular line= 2/3
Answer:
600 feet
Step-by-step explanation:
60 feet per minute
m = minute
60m
60(10)
600 feet
Answer:
Step-by-step explanation:
Ray hired sun and peter to help him move.
Let h represent the number of hours that each of them worked.
Let y represent Ray's total cost for hiring Sun and Peter for h hours.
Sun charged a $20 flat fee and $30 per hour. The total amount that Sun charges would be
20 + 30h
Peter charged $25 per hour. The total amount that Peter charges would be
25h
An expression for Ray's total cost if Sun and Peter each work h hours would be
y = 20 + 30h + 25h
y = 20 + 55h
Answer:
[20+(30+25)]h or (20+55)h
Step-by-step explanation:
20 will not be changed.
Total cost per hour is 55
add $20

we know that
the volume of a rectangular prism is equal to
where
L is the length of the box
W is the width of the box
H is is the height of the box
in this problem we have
Convert feet to inches
we know that
feet is equal to
inches
so
Find the volume
therefore
the answer is
Convert 1.3 ft to inches which is 15.6in
then multiply all measurements using the volume formula which is L•W•H
17 * 15.6 * 8 = 2121.6 cubic inches
