You need to take your mom’s old broken washing machine to the dump. You have a dolly on which to move the 200-pound washer, but you want to build a ramp to roll it off of the front porch of your house. You have an 8-foot board with which to make a ramp from your front porch. If the porch is 2 feet high, what is the horizontal distance from the porch that the ramp would reach? Safety guidelines state that the angle of elevation for ramps should be at most 5 degrees. Does your ramp meet safety guidelines? Sketch a picture and solve showing all your work. Round answers to the nearest tenth.

On the way home from visiting his family, vincent’s plane cruised at an altitude of 3.2 × 104 feet. he had heard that a man named felix baumgartner skydived from an altitude of 1.28 × 105 feet. vincent wants to know how much higher felix went on his skydiving trip. question 1 you have already seen how adding numbers works in either scientific notation or standard notation. but can you subtract numbers in scientific notation and get the same results as subtracting in standard notation? to find out, first solve vincent’s problem in standard notation. part a write the cruising altitude of vincent’s plane in standard notation.

Which of these equations, when solved, gives a different value of x than the other three? a9.1 = -0.2x + 10 b10 = 9.1 + 0.2x c10 – 0.2x = 9.1 d9.1 – 10 = 0.2x

Complete the solution of the equation. find the value of y when x equals -5. -4x - 8y = -52
