Answer:
(a) 27 degrees (nearest degree)
(b) 17.9 m (to one decimal place)
Step-by-step explanation:
Wow, that's along ladder, perhaps for the firemen!
From diagram,
(a)
sin(x) = 9 / 20 = 0.45
x = arcsin(0.45) = 26.74 degrees
(b)
height of wall ladder reaches
h = 20*cos(x) = 20*cos(26.74) = 17.86 m
1 worker earns 8/hour for 40 hrs.8 times 40=320 dollars in amount for 1st worker.the 2nd worker has the same 8 hrs for 40 hours therefore the same amounts.320+320=640
as a percentage:640 divided by 2000=0.32
0.32 times 100
=32 percent for both workers.16 percent for only 1 worker<span />
Slope = (change in 'y') / (change in 'x')
If you find two points where the line goes through the corners of boxes,
then count up the 'y' boxes and the 'x' boxes between those two points,
you'll find that the line rises 3 y-boxes for each x-box.
The slope of the line is 3 .
Answer:
a
Why:
The radical is being multiplied by itself 4 times.
Answer:
36 gallons
Step-by-step explanation:
y = 4/5x
Let x = 45 minutes
y = 4/5 (45)
y = 36 gallons
