Linear equations Two friends rent an apartment for $975 per month. Since one bedroom is 60 square feet larger than the other bedroom , each person's rent contribution is based on the bedroom size. Each person agrees to pay $3.25 per square foot of bedroom size. Let x be the area of the larger bedroom, and let y be the area of the smaller bedroom. Write and solve a system of linear equations to find the area of each bedroom.

This question is strangely worded and does not pertain to floppy drives. However, taking all information here as given and sufficient enough to form the equations, you arrive at the following:

60(3.25) = 195 One tenant must pay $195 more for his extra 60square ft.
(975-195)/2=390 The remaining rent (assuming the given info is all that is needed to solve)
390/3.25=120 is divided between the two and represents the rent of the smaller bedroom.
y=120 sq ft The rent of the smaller room holder is divided by $3.25 to reach the sq ft.
x=180 sq ft

How many linear feet is in 18square feet

You would need the dimensions of the item that you are trying to calculate the distance on. For example, a 12 inch by 12 inch tile is one square foot. 18 of them would be 18 square feet. If you place them end-to-end you would have 18 linear feet. However, if you had a 6 inch by 12 inch tile, it would take 36 of them to get 18 square feet. If you lined the tiles up in a row on the 6 inch side, you would have 18 linear feet. If you lined them up on the 12 inch side, you would have 36 linear feet. Linear feet does not take into account width, only length. So trying to translate a 2-dimensional value into a 1-dimensional value is difficult if not impossible without more details.

Need to know how to figure sq ft of a home and bedroom

For your home. Measure back to front and side to side in feet. If your home is 60 feet by 80 feet, you multiply the two numbers together and then multiply that answer by the number of floors.

The bedroom, you just multiply the width by the depth, so if it was 21 feet by 12 feet, 21x12 would be 252 square feet.

How many linear feet is a fense 25x25x25ft? The cost of the fense about $15.00 per linear foot.

I am assuming you are talking about fencing in 3 sides of an area with each side being 25 feet long. Linear feet refers to only the running length of the fence. It doesn't care about height. For example, you fence will be 75 linear feet long...three sides each 25 feet. The price per linear foot already takes into account the fence height. For example, you say that the fence you want is about $15.00 per linear foot. For the sake of argument, say your fence is 4 feet high. If you were to change to a 3 foot high fence, the cost per linear foot would be less since there is less fencing material. If you wanted to up the height to 6 feet, the price would rise accordingly.

9 linear feet equal how many sq ft?

It equals zero square feet.
Linear feet is only one dimension (length). You need 2 dimensions to calculate square feet. In other words, you need *width* also.
But IF you're asking how many square feet is 9 linear feet (long) by 9 linear feet (wide), then the answer is 81.

How many feet is 350 linear feet?

Linear feet are a measure of length (no different from feet); square feet measure area. You cannot simply convert between measures of different kinds of quantities;the connection between them will be specific to a particular problem.A practical example in which this question can arise is in buying countertops for a kitchen. Some materials are sold by the square foot; others (basically those that are extruded, so they come in standard widths) are sold by the linear foot. In order to compare the two, you need to compute the area and wall length for the countertop you want.You can't convert between the two. All you have to do is to make the appropriate measurements so you can calculate the price of each item.The terms used in the lumber industry are a bit confusing.There are two terms that I think you might be mixing up.A LINEAR FOOT is simply the length of a board. If you want to know the area or volume of the board,you need additional information. For instance, 6 linear feet of 1-by-12 has an area of 6 square feet (12 inches = 1 foot, times 6 feet), and it's 1 inch thick, so the volume is 1/2 cubic foot (6 square feet times 1/12 foot). But 6 linear feet of a 1-by-6 board would have half the area and half the volume.A BOARD FOOT is equivalent to one square foot of a 1-inch-thick board. In other words, it is a square-foot-inch (ft^2-in), or 1/12 cubic foot.Linear feet are used for the pricing of a single size such as two-by-fours. Board feet are used for larger lumber that you are more likely to want to compare directly with different size boards .To sum up, neither a linear foot nor a board foot can be converted directly to square feet. A linear foot is a linear (length) measure, and a board foot is a volume measure. You need to know your particular board to do anything more, such as find the example with an" L" shaped countertop will betwo rectangles are 24 by 80 inches and 24 by 36 inches. Thus the area is: 24 * 80 + 24 * 36 = 24 * (80 + 36) = 24 * 116= 2784 sq. in.To get it in square feet, divide by 144:
2784 / 144 = 19.33 sq. ft.The linear measure of this countertop would be 60 + 80 = 140 inches = 140/12 feet = 11.67 feet

Quadratic formula

The answer is yes.

The acceleration due to gravity is approximately 32 feet per second or 9.8 meters per second. If you're measuring the distance in feet use 16, if you're measuring in meters then use 4.9.

If I walk 26 sq feet for every 10 steps then what is my stride? I am having a hard time figuring this out or the pedometer is very inaccurate.

you cant walk in square feet as this is an area.
you walk in linear feet. a straight line.
if you walk 26 linear feet in 10 strides then your stride length is 2.6 feet or 2 and a half feet per step.
