Marina86 [1]

The total number of persons standing in the line waiting for ordering pizza are 5.

Explanation:

There are 5 people in total so the first place can be occupied by any of the 5 persons.

Secondly the second place in the line can be occupied by any of the 4 persons left.

Then the third place will be occupied by any remaining 3 persons as the front two places are already occupied.

Similarly the fourth place will be taken by any of the remaining two people. And lastly the last place will b filled by the last remaining person.

So the total number of ways will be 5*4*3*2*1 = 120 ways that is given in the question.

lakkis [162]

$50\times\frac{26}{100}\\\\=\frac{50\times26}{100}\\\\=\frac{1300}{100}\\\\=13\\\\50-13={\boxed{ \bf 37}}$

50 points decreased by 26% is 37 points.

$50\times\frac{26}{100}\\\\= 50 \times 0.26\\\\=13\\\\ 50-13={\boxed{ \bf 37}}$

50 points decreased by 26% is 37 points.

Simplify (4ab^2)^3<br><br> Any help is appreciated

Pie

Answer:

$64a^{3} b^{6}$

Step-by-step explanation:

1) Distribute the exponent outside of the parentheses to the terms inside the parentheses. In this case, multiply the 3 outside the parentheses with the exponent of each of the terms inside:

$(4ab^{2} )^3$

$4^{3}$ · $a^{3}$ · $b^{6}$

2) The variables are fine - you can't simplify them further. All you need to do now is multiply the $4^{3}$ out. Remember that it's kind of like asking, "what is 4 × 4 ×4?"

$4$ · $4$ · $4$ · $a^{3}$ · $b^{6}$

$16$ · $4$ · $a^{3}$ · $b^{6}$

$64a^{3} b^{6}$

Therefore, $64a^{3} b^{6}$ is the answer.

$\sqrt{45} =\sqrt{3 \times 3 \times 5}$

$\sqrt{45} =3\sqrt{5}$

$3\sqrt{5}$ is an irrational number, it cannot be expressed in the form of a fraction.
