Answer:
C
Step-by-step explanation:
A. 2*6 = 12 but 24p*2 doesn't equal 24p
B. 3*9 doesn't equal 12, and 3*21p doesn't equal 24p
C. 4*3 equals 12 and4*6p=24p
D. 6*2=12, but 6*3p doesn't equal 24p
I hope this helps!!!
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>
Answer:
These are Vertical angles, adjacent angles are next to each other and make up a whole angle, while vertical angles are across and equal the same thing.
X = 81 because 84 and (x + 3) are the same so 84 minus 3 is 81
Hope that helps
Answer: x=1.32
