A plane flies 910 miles with the wind in the same time it can go 660 miles against the wind. The speed of the plane is still air

lorasvet [3.4K]

Answer:

The speed of the wind is 48.56

Step-by-step explanation:

We can use the following formula to calculate the distance:

distance = speed x time

Let w represent the speed of the wind.

If the plane flies with the wind, the speed will be the speed of the plane + the speed of wind. Since it can fly 910 miles, and the speed of the plane is 305

910 = (305 + w) x time (1)

If the plane flies against the wind, the speed will be the speed of the plane - the speed of wind. Since it can fly 660 miles, and the speed of the plane is 305

660 = (305 - w) x time (2)

Since the time is equal for both equation in 1 and 2:

$\frac{910}{305+w}$ = $\frac{660}{305-w}$

→ 910(305-w) = 660(305+w)

→ 277550 - 910 w = 201300 + 660w

→ 1570w = 76250

→ w = 48.56

Decrease 28 by 7% immmmmmmmmm soooooooo stuck

iris [78.8K]

First, multiply 28 x 7/100
then subtract the product from 28
therefore:
28 - (7/100 x 28)

A sample of 100 cans of peas showed an average weight of 14 ounces with a standard deviation of 0.7 ounces. If the distribution

Roman55 [17]

This is an example of a normal distribution. An average weight is 14 ounces and a standard deviation is 0.7 ounces.
14.7 = 14 + 0.7 = Average + 1 Standard Deviation.
It means that the percent of cans that will weigh over 14.7 ounces is:
100% - ( 50 % + 34 % ) = 100% - 84% = 16%
16% of 100 cans: 16/100 * 100 = 16.
Answer: 16 cans.
