find the area of the regular hexagon PQRSTU of sides 8 cm as shown in the figure

Answers

Answer:

Area = 245m^2

Step-by-step explanation:

We can split this figure into 2 parts, a rectangle and a trapezoid.

Rectangle Sides = 10m and 20m

Area = 10m x 20m = 200m

Trapezoid formula = a+b/2(h)

a and b are the 2 bases and h is the height

Using a little deductive reasoning we get the following, 5+10/2(6)

This simplifies to 15/2(6) -->

7.5(6) = 45

Thus, our area is 200 + 45, or 245m^2

Rita is adding 3 + (negative 8) + 1. She rewrites the expression as 3 + (negative 1) + 8. What is Rita’s error? She used the commutative property, which cannot be used with negative numbers.

A gym charges $8.75 for each swimming class and a one-time registration fee of $12.50. A student paid a total of $56.25. How many swim classes did the student take?

Answers

Answer:

He took 5 swimming classes.

Step-by-step explanation:

The problem states that the student paid a total of $56.25 for the classes and also the one-time registration fee. To find the number of classes, we should first subtract the one-time registration fee from the total.

$56.25 - $12.50 = $43.75

Now that we know he spent a total of $43.75 on the classes without the registration fee, we can divide that number by the cost of one class ($8.75) to calculate the total number of classes he took.

43.75 / 8.75 = 5

Answers

Answer: x = 160

Step-by-step explanation:

540 = 100+(x-25)+(x-15)+(1/2)x+(1/2)x

540= 100-40+3x = 60+3x

480 = 3x

x = 160

Answer:

0.5x + 0.5x + (x-25) + (x-15) + 100 = 540

x + x - 25 + x - 15 + 100 = 540

3x + 60 = 540

3x = 540 - 60

3x = 480

x = 480/3

x = 160

Based on the graph, which inequality is correct for a number that is to the left of -4?

a
−7 > −4
b
−6 −4
d
−4 < −9

Answers

Answer:

From the graph, it is clear that the left of -4 will always be lesser than the -4.

and -6 is the left of -4. so -6 will be lesser than -4.

so, [tex]-6 < -4[/tex] is the correct option.

Therefore, the option 'd' is the correct answer.

Step-by-step explanation:

Let us analyze all the given inequalities

Given the inequality

[tex]-7\:>-4[/tex]

As -7 can not be greater than -4, so [tex]-7\:>-4[/tex] is false.

Given the inequality

[tex]-8>-4[/tex]

As -8 can not be greater than -4, so [tex]-8>-4[/tex] is false.

Given the inequality

[tex]-4 < -9[/tex]

As -4 can not be lesser than -9, so [tex]-4 < -9[/tex] is false.

Given the inequality

[tex]-6 < -4[/tex]

As -4 is always greater than -6, so [tex]-6 < -4[/tex] will be true.

From the graph, it is clear that the left of -4 will always be lesser than the -4.

and -6 is the left of -4. so -6 will be lesser than -4.

so, [tex]-6 < -4[/tex] is the correct option.

Therefore, the option 'd' is the correct answer.

A parent is using a garden hose to fill up a small inflatable pool for her young child. The pool has a capacity of 90 gallons. She turns the water off after 5 minutes, but leaves the hose in the pool for another 3 minutes before putting it away.

In this situation, the relationship between the gallons of water in the pool and the 8 minutes since the parent started filling the pool can be seen as a function.

In that function, which variable is independent? Which one is dependent?

Type your response in the space below.

Answers

Answer:

Independent variable = the time. Dependent variable = amount of water per minute

Step-by-step explanation;

The total amount of water depends on how long the hose is left on.

The relationship between the gallons of water in the pool and the 8 minutes since the parent started filling the pool can be seen as a function is ''the total amount of water depends on how long the hose is left on''.

Time is the independent variable.

The amount of water per minute is the dependent variable.

Given

A parent is using a garden hose to fill up a small inflatable pool for her young child.

The pool has a capacity of 90 gallons.

She turns the water off after 5 minutes but leaves the hose in the pool for another 3 minutes before putting it away.

What is the independent variable?

Independent variables are the variables that the experimenter changes to test their dependent variable.

What is the dependent variable?

A change in the independent variable directly causes a change in the dependent variable.

1. The relationship between the gallons of water in the pool and the 8 minutes since the parent started filling the pool can be seen as a function is ''the total amount of water depends on how long the hose is left on''.

2. Time is the independent variable.

3. Amount of water per minute is the dependent variable.

19. If the triangle below is equilateral, write an
expression using parentheses to show the
perimeter of the triangle. Then, give the
simplified expression.
4x - 3

Answers

Answer:

Perimeter of the triangle = (12x - 9)

Step-by-step explanation:

Property of an equilateral triangle:

- All sides are equal in measure.

- All interior angles are equal.

Since, measure of one side of the triangle = (4x - 3)

And perimeter of a polygon = Sum of all sides of the polygon

Therefore, perimeter of the given triangle = (4x - 3) + (4x - 3) + (4x - 3)

= (4x + 4x + 4x) - (3 + 3 + 3)

= (12x - 9)

Perimeter of the triangle = (12x - 9)
