Answer:

4.2*10^{-1}

Step-by-step explanation:

We want to simplify:

2.1*10^{-3}\times 2*10^2

We rewrite to get:

2.1*2*10^2*10^{-3}\times10^2

We now apply the laws of indices

4.2*10^{-3+2}

We simplify to get 4.2*10^{-1}

We leave our final answer is scientific form.

The final answer is therefore:

4.2*10^{-1}

Mr. Inahurry sold his house for $27,000, which is a 10% loss over what he originally paid for it. What did he pay for the house
Ainat [17]

Answer: $30,000

Step-by-step explanation:

If Mr. Inahurry had a 10% loss, it means that he paid X for the house and only got back 90% (100% - 10%) of what he paid.

This way X . 90% = 27,000

               X . 0.90 = 27,000

               X = 27,000/0.9

               X = 30,000

Counter-proof: 30,000 . 10% = 30,000 . 0.10 = 3,000

                          30,000 - 3,000 = 27,000

Someone PLSSS HELPPPP !!!!
AnnZ [28]

Answer:

p^3  / q^12

Step-by-step explanation:

p^6 q^4

------------------

p^3 q^16

We know a^b / a^c = a^(b-c)

First with variable p

p^6 /  p ^3 = p^(6-3) = p^3

Then with variable q

q^4 / q^16 = q^(4-16) = q^-12  and a^-b = 1/ a^b = 1 /q^12

p^3 * 1/ q^12

p^3  / q^12

Can anyone help me out? thanks
Alik [6]

Answer:

450 cm

Step-by-step explanation:

12 degrees is 1/30 of the circumference because there are 360 degrees in a circle.

The minor arc length of 15 is in the same ratio to the circumference as  the 2 angles , so the circumference = 30 * 15 - 450 cm.
