1. Express the rate in lowest terms. The ratio of $2.25 to 6.75 ounces. 2. find the average rate of speed, expressed in miles per hour (unite rate). a post office truck delivered mail on a 9-mile route in 2 hours.
3. Does x/2 = 16/4 have the same solution as x/16 = 4/2. Use the cross products property to explain your answer.
4. Solve the proportion. 2x/5 = 9/15.
5. Tell whether the statement is true or false. Explain. If a/b = 2/3, then 3/2 = b/a. Use the cross product property to explain your answer.

Successful implementation of a new system is based on three independent modules. module 1 works properly with probability 0.96. for modules 2 and 3, these probabilities equal 0.95 and 0.90. compute the probability that at least one of these three modules fails to work properly.

You are updating your garage and the only thing left to paint is your garage day. you're only going to paint the slide that faces the street. the garage door is 9 fert 8inches tall and 120 inches wide. you need to know the surface area of the side of the garage door to determine how much paint to buy. the hardware store sells paint by how much covers a square foot. what is the surface area you should report to the hardware store what is the answer

An airplane consumes fuel at a constant rate while flying through clear skies, and it consumes fuel at a rate of 64 gallons per minute while flying through rain clouds. let c represent the number of minutes the plane can fly through clear skies and r represent the number of minutes the plane can fly through rain clouds without consuming all of its fuel. 56c+64r < 900056c+64r< 9000 according to the inequality, at what rate does the airplane consume fuel while flying through clear skies, and how much fuel does it have before takeoff? the airplane consumes fuel at a rate of gallons per minute while flying through clear skies, and it has gallons of fuel before takeoff. does the airplane have enough fuel to fly for 60 minutes through clear skies and 90 minutes through rain clouds?
