Solve for x in equation <br> x-c/2=d
lana66690 [7]
X-c/2 = d
Multiply by 2 on both sides. Leaves us with:
x-c = 2d
Add 2 to both sides. Leaves us with:
x = 2d + c
Unless you have values to substitute into the variables, this is your answer:
x = 2d + c

Find the work done in emptying a cylindrical tank filled with water. The water is being pumped out from the 6 top. The tank has
lutik1710 [3]

Answer:

<em>908360.67 lb-ft</em>

<em></em>

Step-by-step explanation:

height of tank= 6 ft

diameter of the tank = 4 ft

density of water p = 62.4 lbs/ft

A is the cross sectional area of the tank

A = \pi r^{2}

where r = diameter/2 =  4/2 = 2 ft

A = 3.142 x 2^{2} = 12.568 ft^2

work done = force x distance through which force is moved

work = F x d

Force  due to the water = pgAh

where g = acceleration due to gravity = 32.174 ft/s^2

Force  = 62.4 x 32.174 x 12.568 x 6 =  151393.44 lb

work done = force x distance moved

work = 151393.44 x 6 = <em>908360.67 lb-ft</em>

The area of a rectangle is 27m and the length of the rectangle is 3m less then twice the width. Find the dimensions of the recta
Zielflug [23.3K]

Answer:

w = 4 1/2

l = 6

Step-by-step explanation:

w = width

2w-3 = length

A = lw

27 = w(2w-3)

27 = 2w² - 3w

subtract 27 from each side:

2w² - 3w - 27 = 0

factor:

(2w-9)(w+3) = 0

solve each for 'w':

w = 9/2

w = -3  (This answer can be discounted because a length cannot be negative)

width = 9/2

length = 2(9/2) - 3 which is 6
