Luis saw a rectangular swimming pool that has a perimeter of 50m and a width of
10m. what is the length, in meters, of the swimming pool?

15 meters

Step-by-step explanation:

What we know:

Total perimeter: 50m

Width: 10m

Since we have the width, we know that two sides of the pool are 10 meters long.

10m+10m=20m

Thus, the two smaller edges of the pool are 20m combined. We can subtract this from the total perimeter to find the total length of both longer sides combined.

50m-20m=30m

Now we know that the two long sides combined are 30 meters. We also know that since the pool is rectangular, these sides are of equal length, so we can divide the 30 meters between the two sides equally.

30/2=15

This means that each long side is 15 meters long, and the length of the pool is 15 meters.

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies

what chart am i supposed to follow?
