Mean is just another word for average. To find the average of something you must add up all values and divide by the number of values in the set.

Assume that y varies directly with x. If y = 16 when x = 8, find y when x = 5.

dem82 [27]

Answer:

Step-by-step explanation:

5y + x = 25

Subtract x from both sides when x = 5

5y + x - x = 25 - x

5y = 20

5y/5 = 20/5

Y=4

How many miles are equivalent to 3.1 kilometers? 1 kilometer is about 0.62 mile

Anton [14]

Answer:

1.922 miles is equivalent to 3.1 kilometers.

Step-by-step explanation:

Given:

1 km = 0.62 miles.

3.1 km = ? miles

Now, in order to find the number of miles equivalent to 3.1 km, we use unitary method with the help of the conversion factor.

From the conversion factor, we can conclude that kilometer is a smaller unit compared to that of mile.

So, conversion factor = $\frac{0.62\ miles}{1\ km}$

The formula to transform 'n' kilometers to miles is given as:

$=Conversion\ factor\times n$

Therefore, 3.1 km = $\frac{0.62\ miles}{1\ km}\times 3.1\ km$

3.1 km = $1.922$ miles

Therefore, 1.922 miles is equivalent to 3.1 kilometers.

9 ft./s into miles per hour

nexus9112 [7]

First multiply 9 by 60 to find feet/minute: 9x60=540. Multiply that answer by 60 to get feet/hour: 540x60=32400. Divide that by 5,280 to get miles/hour: 32400/5280=6.14 roughly :)
