1. ## physics

A basketball player throws the ball at a 53degree angle above the horizontal to a hoop which is located a horizontal distance L = 2.4 m from the point of release and at a height h = 0.9 m above it.What is the required speed if the basketball is to reach

There are 38 houses in a new community available with two floor plans. Floor plan x sells for $175,000 and Floor plan y sells for$200,000. The total worth of all available homes are $7,200,000. Write an equation that illustrates this situation. Part A: asked on March 25, 2010 3. ## Chemistry I have to fill in the missing values in this invisible chart The cation is Sn+2, the Anion is SiO3^-2. I think the compound is SnSiO3, and the name is silicite. Is this right? The cation is Al3+, the anion is S^-2. I guessed the compound was Al2S3, and the asked on March 9, 2009 4. ## physics A stone is thrown at 15 m/s an angle \theta below the horizontal from a cliff of height H. It lands 78 m from the base 6 s later. Find \theta and H. asked on September 27, 2014 5. ## physics A ball is thrown at 14 m/s at 57° above the horizontal. Someone located 30 m away along the line3 of the path starts to run just as the ball is thrown. How fast, and in which direction, must the catcher run to catch the ball at the level from which it was asked on September 27, 2014 6. ## Math 116 algebra Imagine you are in the market for a new home and are interested in a new housing community under construction in a different city. The sales representative informs you that there are 56 houses for sale two floor plans still available.

3. ## Math 116 algebra

Thank you once again. I was getting the same answers but I was wondering if I was wrong. Seems you made it correct in thought for me. Here is another one: The sales representative here tells you they also have two floor plans available at another community

4. ## Math 116 algebra

my problem with the first one is how did you get a 4 when it is 3 times as many? would that 4 be a three instead and does that change the outcome of the solution?

5. ## Math 116 algebra

thank you. Now using Part A and B what is the intercepts of part A and what are the intercepts of part b? Where would the lines intersect if you solved the system by graphing?

7. ## Math 116 algebra

Now using the equations from Part A and Part B. use substitution to determine how many of each type of floor plan is available. Describe the steps you used to solve the problem

8. ## Math 116 algebra

Not quite understanding since the y is only now 3 times more than x so shouldn't the variable stay the same as in the first part when making the equation?

9. ## math 116

An inequality shows two statements that are true only if one statement differs from the other by being greater than, or equal to the other. ex: x+1>3 changing > to = then x will be x=2 now substitute the > gives you x>2. Inequalities have multiple

thanks I thought the same. Now the second question is The sales representative later indicates that there are three times as many homes available with the second floor plan than the first. Write an equation that illustrates this situation. Use the same
