Answer:

Solving the equation \frac{a^2-b^2}{2+d^3} by putting a=6, b=4 and d=1/2 we get \frac{160}{17}

Step-by-step explanation:

We are given formula: \frac{a^2-b^2}{2+d^3}

and values a=6, b=4 and d=1/2

We need to put the values of a, b and d in the given equation \frac{a^2-b^2}{2+d^3} and find their result

Putting values in the equation:

\frac{a^2-b^2}{2+d^3}\\=\frac{(6)^2-(4)^2}{2+(\frac{1}{2})^3}\\=\frac{36-16}{2+\frac{1}{8}}\\=\frac{20}{\frac{2*8+1}{8}}\\=\frac{20}{\frac{17}{8}}\\=\frac{20*8}{17}\\=\frac{160}{17}

So, solving the equation \frac{a^2-b^2}{2+d^3} by putting a=6, b=4 and d=1/2 we get \frac{160}{17}

An mp3 player is on sale for 30% off the regular price of $39. 98. How much is the discount? a. $11. 99 b. $13. 19 c. $13. 33 d.
Andrej [43]

The cost of the mp3 player after the discount is $27.98.

<h3>What is percentage?</h3>

A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate percent of a number, divide the number by whole and multiply by 100.

Given

An mp3 player is on sale for 30% off the regular price of $39. 98.

The price of the mp3 player after the 30% is given

\rm Cost \ of \ player \ after \ discount = Cost \ of \ player \times discount\\\\\rm Cost \ of \ player \ after \ discount = 39.98\times 0.30\\\\\rm Cost \ of \ player \ after \ discount = 11.99

The cost of mp3 player after 30% discount is;

= $39.98 - $11.99 = $27.98

Hence, the cost of the mp3 player after the discount is $27.98.

What is the product of − 3/11 and − 2/15? please explain.
emmainna [20.7K]

ANSWER

The product is

\frac{2}{55}

EXPLANATION

To find the product of

-  \frac{3}{11}

and

\frac{ - 2}{15}

means we should multiply the two fractions.

We multiply to obtain,

-  \frac{3}{11}  \times  -  \frac{2}{15}

=  -  \frac{3}{11}  \times  -  \frac{2}{3 \times 5}

Cancel the common factors:

=  -  \frac{1}{11}  \times  -  \frac{2}{5}

Now, multiply the numerators separately and the denominators too separately.

=  \frac{ - 1 \times  - 2}{11 \times 5}

This simplifies to,

= \frac{2}{55}

20 - 4b/8= 18<br><br> another one :)
Crazy boy [7]

multiply by 8 on both sides

(20)8 - 8(4b/8) = (18)8

160 - 4b = 144

subtract 160 on both sides

160 - 160 - 4b = 144 - 160

-4b = -16

divide by -4 on both sides

-4b/-4 = -16/-4

b = 4
