Answer:

180

Step-by-step explanation:

1 foot a minute = 0.0113636364 miles a hour

15840 • 0.0113636364 = 180.000001

So pretty much just round down

The simplified expression of $$4 x \cdot \frac{1}{x^{-5}} \cdot x^{-3}$ is $4x^3$ .

Solution:

Given expression is $4 x \cdot \frac{1}{x^{-5}} \cdot x^{-3}$ .

To simplify the given expression.

$$\Rightarrow4 x \cdot \frac{1}{x^{-5}} \cdot x^{-3}$

Using exponent rule: $\frac{1}{a^{-m}}=a^m$

$$\Rightarrow4x \cdot x^{5}.x^{-3}$

Using another exponent rule: $a^m \cdot a^n=a^{m+n}$

$$\Rightarrow4x \cdot x^{5-3}$

$$\Rightarrow4x \cdot x^{2}$

Using exponent rule: $a^m \cdot a^n=a^{m+n}$

$$\Rightarrow4x^{1+2}$

$$\Rightarrow4x^3$

Hence the simplified expression of $$4 x \cdot \frac{1}{x^{-5}} \cdot x^{-3}$ is $4x^3$ .

Answer:

G, 113.04

Step-by-step explanation:

To find the area of the head of the nail you need to use the*

> A= π*r^2* A equals area, π equals pi(3.14) and then you square your raidius, which is 6 in your case.

π*r^2

plug in your six as the *r

π*6*^2

solve 6^2=36 and multiply that by your π which is 3.14

3.14*36

=113.04

Hope that helped!! :)
