Reptile [31]

Answer:

Step-by-step explanation:

Original rectangle: 100 cm by 200 cm

Original area: 100 cm * 200 cm = 20,000 cm^2

Reduced by 70%, the measures are now 30% of they they were.

30% of 100 cm = 30 cm

30% of 200 cm = 60 cm

New area: 30 cm * 60 cm = 1800 cm^3

New area equals what percent of original area?

1800/20,000 * 100 = 9%

Can someone help please

yanalaym [24]

Step-by-step explanation:

a) The volume of the prism is

$V = (n^2 - 1)×(n^2 - 1)×(5n)$

$\:\:\:\:= (n^4 - 2n^2 + 1)(5n)$

$\:\:\:\:=5n^5 - 10n^3 + 5n$

b) If the dimensions L of the prism are tripled, the new volume will be

$V' = (3L)^3 = 27L^3 = 27V$

so it will increase by a factor of 27.

Question NEEDS ANSWERING

labwork [276]

The numeric value of the given expression is as follows:

121/900.

<h3>Numeric value of expression</h3>

The expression is defined as follows:

$\left(-\frac{1}{3} + 0.6\left(-\frac{1}{2}\right) + 1\right)^2$

The parenthesis take precedence. If there are more than one parenthesis, the inside one takes precedence.

The fraction equivalent of 0.6 is of 3/5, hence:

$\left(-\frac{1}{3} + \frac{3}{5}\left(-\frac{1}{2}\right) + 1\right)^2$

Solving the internal parenthesis, the expression is:

$\left(-\frac{1}{3} - \frac{3}{10} + 1\right)^2$

The least common multiple of 3, 10 and 1 is of 30, hence:

$\left(-\frac{1}{3} - \frac{3}{10} + 1\right)^2 = \left(\frac{-10 - 9 + 30}{30}\right)^2 = \left(\frac{11}{30}\right)^2$

To find the square of the fraction, we find the square of the numerator and the denominator, hence the numeric value of the expression is:

121/900.

<h3>Missing information</h3>

The expression is:

$\left(-\frac{1}{3} + 0.6\left(-\frac{1}{2}\right) + 1\right)^2$
