Step-by-step explanation:

A'B'/AB = 5.1/1.7 = 3

B'C'/BC = 7.2/2.4 = 3

A'C'/AC = 7.5/2.5 = 3

These ratios are equal to the scale factor. These ratios are the scale factor.

The rule for the area of a polygon is as follows:

Area of a Polygon = Apothem x Perimeter ÷ 2

So, add all the of the outside measurements together to find the Perimeter but I don't know where the Apothem in the polygons are.

I hope this gives you some sort of a lead. :)

How to simply 1 over 9 divided by 5 over 6

allsm [11]

Simply 1 over 9 divided by 5 over 6 is $\frac{2}{15}$ or $0.133$ .

<u>Step-by-step explanation:</u>

Here we have , 1 over 9 divided by 5 over 6. It's known to us that x over y means x divides y i.e. x/y or $\frac{x}{y}$ . SO , for an instance we have 1 over 9 as $\frac{1}{9}$ and 5 over 6 as $\frac{5}{6}$ .Now ,its asked to simplify 1 over 9 divided by 5 over 6 i.e.

⇒ 1 over 9 divided by 5 over 6

⇒ $\frac{1}{9}$ ÷ $\frac{5}{6}$

⇒ $\frac{1}{9} (\frac{6}{5} )$

⇒ $\frac{1}{3} (\frac{2}{5} )$

⇒ $\frac{2}{15}$

⇒ $0.133$

Simply 1 over 9 divided by 5 over 6 is $\frac{2}{15}$ or $0.133$ .

The temperature changes can be represented by the expression -0.5( 1 -2h).Chase says that the temperature change can also be rep

UNO [17]

Answer:

The expression are equivalent

Step-by-step explanation:

The question requests that we show whether the equation -0.5( 1 -2h) is equivalent to 4(2h + 2) - 7h - 8.5 or not :

Simplifying 4(2h + 2) - 7h - 8.5 ; we have ;

4(2h + 2) - 7h - 8.5

8h + 8 - 7h - 8.5

8h - 7h + 8 - 8.5

h - 0.5

-0.5(1 - 2h)

-0.5 + h

= h - 0.5

Hence, both expressions are the same

How do you do inequalities

sineoko [7]

Answer:

See description below.

Step-by-step explanation:

An inequality is an equation with more than one solution and they use <, >, $\leq$ or $\geq$ . There are a number of ways to work with inequalities.

Solving: To solve inequalities in one variable, treat it just like an equation. Solve using inverse operations. If you divide or multiply by a -1 then be sure to flip the sign. For example, if you have > then it becomes <.

Graphing on a number line: To graph inequalities in one variable, use a number line. Plot a point on the number line with an open circle then an arrow pointing toward the solution set. If you have an equal to, you would shade in the open circle.

Solving: To solve inequalities in two variables, you need a system meaning more than one. You solve it like a system of equations by graphing.

Graphing: To graph inequalities with two variables, graph each in y=mx+b form using the y-intercept and slope. Connect the points with a dashed line unless equal to. Equal to inequalities have a solid line. To show the solution set, shade the side of the inequality which (x,y) points make it true. To find this, test a point by substituting into the inequalities.
