Y = 40 + 4m
m = minutes
y = total papers graded
<h3>
Answer: Choice D) 22.5</h3>
========================================
Explanation:
x = length of BC
AC = AB+BC
AC = 6 + x
CE = CD+DE
CE = 22+8
CE = 30
Triangles ACE and BCD are similar triangles (can be proven by the AA similarity theorem due to the fact that AE || BD)
Therefore the corresponding sides are proportional letting us set up the proportion below
AC/BC = CE/CD
(6+x)/x = 30/22 .... substitution
22(6+x) = 30x ... cross multiply
132+22x = 30x
132 = 30x-22x ..... subtract 22x from both sides
132 = 8x
8x = 132
x = 132/8 .... divide both sides by 8
x = 16.5
Now use this to find the length of AC
AC = 6+x
AC = 6+16.5
AC = 22.5
V =πr^2h
v= 3.14×27×27×15
v=34335.9
v= 34336
Answer:
the slope is 2
Step-by-step explanation:
take y2 and y1 and subtract them, 11 - 5 = 6
then take x2 and x1 and subtract them, 5 - 2 = 3
then divide those 2 numbers, 6/3 and you get 2
