If you calculate 20-3.58 the answer is $16.42

Hi! I'm happy to help!

When Jenna bought the milk, it deducted (subtracted) $3.58 from her $20. So, let's subtract that here:

20.00

- 3.58

We have to borrow:

19.9(10)

- 3.58

10-8=2

19.9(10)

- 3.58

. 2

9-5=4

19.9(10)

- 3.58

.42

9-3=6

19.9(10)

- 3.58

6.42

and 1-0=1

19.9(10)

- 3.58

$16.42

So, Jenna would receive $16.42 in change for her $20 bill.

I hope this was helpful, keep learning!

Which expression is equivalent to ( 4mn / m^-2n^6)^-2

inn [45]

Here are a few rules with exponents that apply here:

Raising a power to a power: $(x^m)^n=x^{m*n}$
Dividing exponents of the same base: $\frac{x^m}{x^n}=x^{m-n}$
Converting negative exponents to positive ones: $x^{-m}=\frac{1}{x^m}\ \textsf{and}\ \frac{1}{x^{-m}}=x^m$

Firstly, solve the outer exponent:

$(\frac{4mn}{m^{-2}n^{6}})^{-2}=\frac{4^{-2}m^{-2}n^{-2}}{m^{-2*-2}n^{6*-2}}=\frac{4^{-2}m^{-2}n^{-2}}{m^4n^{-12}}$

Next, divide:

$\frac{4^{-2}m^{-2}n^{-2}}{m^4n^{-12}}=4^{-2}m^{-2-4}n^{-2-(-12)}=4^{-2}m^{-6}n^{10}$

Next, convert the negative exponents:

$4^{-2}m^{-6}n^{10}=\frac{n^{10}}{4^2m^6}=\frac{n^{10}}{16m^6}$

Your final answer is n^10/16m^6 , or B.

Simplify the following expression completely, where x is greater than or equal too 0.

Dennis_Churaev [7]

First you want the numbers under the radical to be the same so you can combine like terms.

$x \sqrt{5xy^4} =x \sqrt{5x*^4y} = xy^2 \sqrt{5x}$
$\sqrt{405x^3y^4} = \sqrt{5x*81x^2y^4} =9xy^2 \sqrt{5x}$
$\sqrt{80x^3y^4} = \sqrt{5x*16x^2y^4} = 4xy^2 \sqrt{5x}$

Now add together to get $14xy^2 \sqrt{5x}$

Which equation best describes the pattern in the table below?

cupoosta [38]

Answer:

Step-by-step explanation:

The pattern in the table adds 1.50 for ever 15 minutes. That means per minute it adds $\frac{1.5}{15} =0.10$ or 10 cents. This means you multiply each minute by 0.10 to find the cost. This is the equation c = 0.10m.
