Answer:

5xy^2

Step-by-step explanation:

\dfrac{15x^2y^4}{3xy^2} =

Remember that numbers and variables that have no operation between them are being multiplied, so let's show the multiplications in the numerator and denominator.

= \dfrac{15 \times x^2 \times y^4}{3 \times x \times y^2}

Now separate the fraction into three fractions, one with numbers, one with x, and one with y.

= \dfrac{15}{3} \times \dfrac{x^2}{x} \times \dfrac{y^4}{y^2}

Divide the numbers. For the variables, use the rule that when you divide two powers with the same base, you subtract the exponents. Remember that a variable that shows no exponent has an exponent of 1. A plain x is x^1.

= 5x^{2 - 1}y^{4 - 2}

Now do the subtractions.

= 5x^1y^2

= 5xy^2

Once you get used to these problems, you can do all the calculations in your head and go directly from the question to the answer without having to write all these steps.

Consider multiplying 26.2 by 16.43 what would a mathematician say the answer is
IgorC [24]

In mathematics multiplying decimals is just like multiplying a whole number and ignoring the decimals., then just put the decimals in the answer – it is how many decimals does the two numbers combined.

First step:

Line the numbers on the right and do not a line the decimal points

      26.2

×  16.43

Second Step:

Multiply the numbers starting on the right, just like multiplying a whole number and ignore the decimals.

       26.2

<span> ×  16.43</span>

         786

     1048

   1572

<span>+ 262   </span>

   430466

Third step: add the products

        26.2

<span> ×  16.43</span>

         786

     1048

   1572

<span>+ 262   </span>

   430.466 is the mathematician’s answer.

Answer: Function A; 14 meters per seond

Step-by-step explanation:

do Distance/time for Function A: so you can show 140/10, or 280/20, it doesnt matter as they are all constant/consistent.

A has a rate of 14 m/s

B's  rate is given, 13 m/s

So A has a faster rate of 14 meters per second

vesna_86 [32]
5% of £42 = £2.10
10% of £42 = £4.20
15% of £42 = £6.30

£42 - £6.30 = £35.70

£50 - £35.70 = £14.30

the answer is £14.30
