Answer:

2 \frac{9}{10} pages

Step-by-step explanation:

\begin{aligned}1 \frac{2}{5}+1 \frac{1}{2}&=\dfrac{5 \times 1+2}{5}+\dfrac{2 \times 1+1}{2}\\\\ & =\dfrac{7}{5}+\dfrac{3}{2}\\\\ & =\dfrac{7\times 2}{5 \times 2}+\dfrac{3 \times 5}{2 \times 5}\\\\ & = \dfrac{14}{10}+\dfrac{15}{10}\\\\ & = \dfrac{29}{10}\\\\ & = 2 \dfrac{9}{10}\end{aligned}

Add both amount of pages .

\\ \rm\Rrightarrow 1\dfrac{2}{5}+1\dfrac{1}{2}

\\ \rm\Rrightarrow \dfrac{7}{5}+\dfrac{3}{2}

\\ \rm\Rrightarrow \dfrac{14+15}{10}

\\ \rm\Rrightarrow \dfrac{29}{10}

\\ \rm\Rrightarrow 2\dfrac{9}{10}pages

WHY CAN'T ANYONE HELP ME? 1. In Michigan, the sales tax rate is 6%. Suppose that an item costs $50.88 including tax. How can we
Aliun [14]

Answer: $48

Step-by-step explanation:

From the question, we are told that in Michigan, the sales tax rate is 6% and that an item costs $50.88 including tax.

Let the cost of the item before tax be x. This means that x plus 6% of x equals to $50.88. This can be mathematically expressed as:

x + (6% of x) = $50.88

x + (6/100 × x) = $50.88

x + (0.06 × x) = $50.88

x + 0.06x = $50.88

1.06x = $50.88

When then divide by the coefficient of x

1.06x/1.06 = #50.88/1.06

x = $48

The price before the tax is $48

The image is an example of which type(s) of symmetry
LiRa [457]

Answer:

A. Both rotational and reflectional.

Step-by-step explanation:

We have been given an image of a regular polygon. We are asked to determine type(s) of symmetry for our given polygon.

Upon looking at our given polygon, we can see that it is a pentagon.

We know that a regular pentagon has five equal sides and five lines of symmetry.

We can see that each line of symmetry divides pentagon into two mirror images, therefore, our given pentagon has reflectional symmetry.

We know that the regular polygon has a rotational symmetry. We can find rotational symmetry of a regular polygon by multiplying 360 degrees by number of sides.

\text{Rotational symmetry of pentagon}=\frac{360^{\circ}}{5}

\text{Rotational symmetry of pentagon}=72^{\circ}

Therefore, a regular pentagon has rotational symmetry.
