Calculate 8 ∙ 10-4 divided by 2 ∙ 102. (box after the "10" in answer is for the exponent.). ∙ 10
Korolek [52]

Given problem: \frac{8*10^{-4}}{2*10^2}.

Solution: We can see that first we have 8 and 2 numbers in front of 10's powers.

So, we need to simplify 8 over 2 first.

If we divide 8 by 2, we get 4.

Now, let us work on 10's and their powers.

10^{-4} is being divided by 10^{2}.

We can apply quotient rule of exponents remaining part.

According to quotient rule of exponents, \frac{a^m}{a^n}=a^{m-n}

If we apply same rule, we need to subtract exponents of 10's.

\frac{10^{-4}}{10^2}=10^{-4-(-2)}

If we simplify exponent part -4-(-2), it will give us -4+2 =-2.

So, 10^{-4-(-2)}=10^{-2}

And final answer would be 4 \times 10^{-2}.

The circumference of the base of a cone is 24 inches. The slant height of the cone is 20 inches. What is the surface area of the
nignag [31]

Answer:

Step-by-step explanation:

Given data:

Circumference of the base of the cone = 24in.

Recall that circumference (in this case) is the distance round the base of the cone and from here the diameter D=12in. Radius = 6in

Surface area l = pie x radius ( slant height + radius)

= 3.142 x 6 (20 + 6)

= 3.142 x 6 (26)

= 3.142 x 156

= 490.152in^2
