The average wind speed at a local weather station is 34.8 miles per hour. The highest speed ever recorded the stations 318.0 mil
lukranit [14]

Answer:

Difference = 283.2\ miles/hour

Step-by-step explanation:

Given

Average\ Speed = 34.8\ miles/hour

Highest\ Speed = 318.0\ miles/hour

Required

Determine the difference in the highest speed and the average speed

Difference = Highest\ Speed - Average\ Speed

Difference = 318.0\ miles/hour - 34.8\ miles/hour

Difference = 283.2\ miles/hour

<em>Hence, the highest speed is 283.2 miles/hour faster than the average speed</em>

Store had a sale on our supplies the price p of each item was mark down 60% which expression represents the new price
vlada-n [284]

Answer:

0.4p or p-0.6p

Step-by-step explanation:

We use percents in decimal form to multiply it with the price. We convert percents into decimals by dividing the percent number by 100. For example, 78% divided by 100 becomes 0.78.

There are two ways to look at it:

  • For finding the price we pay during a sale, we focus on the percent we pay. If 60% off is the sale, then we spend 40% or 100-60=40. 40% is 0.40. Multiply that by p an unknown price and we have 0.4p.
  • We can find the percent off by multiplying the price by the percent conversion. So 60% is 0.60. Then subtract it from the original price to find the leftover that we pay. This is p-0.6p.
