For step b. would be 44 divided by 19 = b for step c you can answwer seeing i gave you the equation and along with question a do things you know first then you might have the answers for the rest i hope this helps
Answer:
a:500 b:547,500 c:557,500
Step-by-step explanation:
Answer: -120
Step-by-step explanation:
-40 X 3 = -120
Answer:
x-intercept (2,0) or x=2
y-intercept (0,-4) or y=-4
Step-by-step explanation:
4x-2y>8
2x-y>4
2x-4>y
y<2x-4
y=2x-4
when y=0
2x=4
x=2
x-intercept is (2,0)
and y-intercept is (0,-4)
put x=0,y=0
0-0>8
or 0>8 which is not true. so (0,0) does not lie on the graph.
so graph lies right of the line .
Given:
t1 = 3.6 h
t2 = 4.5 h
x = speed of boat
y = speed of water
Required:
a) Expression of distance traveled with moving water with 3.6h
Expression of distance traveled with moving water with 4.5h
b) Solve for y
c) Percent of boat's speed is the water current
Solution:
Working formula: distance = velocity*time
a) For travelling downstream, we get the equation
d = (x +y)*3.6
For travelling upstream, we get the equation
d = (x-y)*4.5
b) Setting the distance as equal for travelling upstream or downstream, we arrive at the equation of
(x+y)*3.6 = (x-y)*4.5
3.6x + 3.6y = 4.5x - 4.5y
8.1y =0.9x
y = x/9
c) percentage = 1/9*100% = 11.1%
<em>ANSWERS: a) d = (x+y)*36; d = (x-y)*4.5
</em> <em>b) y = x/9
</em> <em>c) 11.1%</em>
