Solve this equation using order and operations:
(I'm trying to check my work, so please explain how you got your answer!)
3 {10[6+2 (22+8) - 10]}

(1680)

Step-by-step explanation:

Simplify the following:

3 (10 (6 + 2 (22 + 8) - 10))

| 1 |  

| 2 | 2

+ | | 8

| 3 | 0:

3 (10 (6 + 2×30 - 10))

2×30 = 60:

3 (10 (6 + 60 - 10))

6 + 60 = 66:

3 (10 66 - 10)

| 6 | 6

- | 1 | 0

| 5 | 6:

3 (10×56)

10×56 = 560:

3 (560)

3 (560) = (3×560):

(3×560)

3×560 = 1680:

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.

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
