Since multiplication is commutative, we can rearrange the problem: 
(1.12*10^5)(6.06*10^5) = (1.12*6.06)(10^5*10^5)
Using the properties of exponents, we have:
(1.12*6.06)(10^10)
\\=6.7872*10^10

Again, multiplication is commutative, so we rearrange the problem; then we use the product property of exponents:
(2*10^1)(3*10^1)
\\=(2*3)(10^1*10^1)
\\=6*10^2

(2.775*10^-^4)(4.775*10^4)
\\=(2.775*4.775)(10^-^4*10^4)
\\=(2.775*4.775)(10^0)
\\=(2.775*4.775)(1)
\\=2.775*4.775=13.250625=1.3250625*10^1

5(8.14*10^2)=(5*8.14)(10^2)=40.7*10^2=4.07*10^3

You work 4 hours on Saturday and 8 hours on Sunday. You also receive a $50 bonus. You earn $164. How much did you earn per hour?
Marina86 [1]
To find the hourly rate, we would first need to take the total earnings and subtract the bonus. $164 - $50 = 114 This gives us the total money earned for hourly work. Then we need to add the total hours worked: 4 + 8 = 12. Lastly, we need to take the total money earned and divide it by the total hours worked: 114 / 12 = 9.50 or $9.50 per hour. The equation could look like: 4h + 8h + $50 = $165

Find the volume of a cone with radius 28 and height 44.
Brut [27]
The volume formula for a cone is V = 1/3 pi r^2 h.  We have everything we need to find the volume. V = 1/3 pi 28^2* 44.  Doing that math and leaving it in terms of pi you have that the volume is 11,498.67 pi units cubed.  If you multiply pi in, the answer would be 36,123.06 units cubed.
