The area A, in square meters, of a rectangle with a perimeter of 200 meters is given by the equation A = 100w − w2, where w is the width of the rectangle in meters. What is the width of a rectangle if its area is 900 m2?
a typical room is 4.0 m long, 5.0 m wide, and 2.5 m high. what is the total mass of oxygen in the room assuming that the gas in the room is STP and that air contains 22% oxygen and 79% nitrogen? is by volume
A rectangular field is three times as long as it is wide. If the perimeter of the field is 160 yards, what are the field's dimensions? The width of the rectangular field is The length of the rectangular field is
find the area the perimeter of a rectangular wall that measures 25 feet long and 15 feet wide
4) A circle with a radius of 2.5 meters. On the perimeter of the circle, there are 30 charges of +12 micro-coulombs and 11 charges of -3 micro-coulombs. If a positive point charge of +7 micro-coulombs with a mass of 11 kg is shot from very, very far away into the middle of the circle, how fast would it need to be going, in m/s, such that the this charge stops in the middle of the circle? Ignore the weight...
(8 points) ). Find the A trough is 7 meters long, 2 meters wide, and 5 meters deep. The vertical cross-section of the trough parallel to an end is shaped like an isoceles triangle (with height 5 meters, and base, on top, of length 2 meters). The trough is full of water (density 1000kg/m amount of work in joules required to empty the trough by pumping the water over the top. (Note: Use g = 9.8m/s2 as the acceleration due...

C. 2. What rectangle has the smallest perimeter, for a given area? Suppose you want a rectangle with area 200. What choice of length L and width W will give the smallest perimeter? a. Sketch a rectangle and label it as having length L and width W. b. Write the area in terms of length and width: A = Write the perimeter in terms of length and width: P = d. If L = 200 and W...
The level of water in an Olympic size swimming pool (50.0 meters long, 25.0 meters wide, and about 2.00 meters deep) needs to be lowered 9.50 cm. If water is pumped out at a rate of 8.40 liters per second, how long will it take to lower the water level 9.50 cm?
(1 point) A basketball gymnasium is 25 meters high, so meters wide and 200 meters long for a halftime stunt the cheerleaders want to run two strings, one from each of the two comers above one basket to the diagonally opposite comers of the gym floor. What is the cosine of the angle made by the strings as they cross? cos(0) =
A trough is 8 meters long, 1 meters wide, and 2 meters deep.
