Answer:
V=31 ft cubed
Step-by-step explanation:
So Volume= length × width × height
V=5×5×1= 25ft cubed
V=2×3×1=6ft cubed
V=6+25
V=31 feet cubed
The central angle and the length of arc are related by the formula:
Length of arc = (θ/360) * 2πr
Where θ = Central angle.
If the central angle is one quarter of the entire circle, the length of arc would also be one quarter of the entire circumference of the circle.

1,2,3,5
Step-by-step explanation:
1-Is your job as an IT administrator stressful?
2-What is your biggest source of stress?

5-Have you ever considered switching careers because of on-the-job stress?
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>
