The area of the given figure  156.75 sq cm.

Step-by-step explanation:

Here,

The figure is a trapezium.

In this trapezium

a = 22 cm

b = 6.5 cm

A and b are the length of two parallel sides.

Height (h) = 5.5 cm

To find the area of the figure which is consists of two trapezium

Formula

Area of the trapezium = [tex]\frac{1}{2} (a+b)h[/tex]

Now,

The area of one trapezium = [tex]\frac{1}{2} (22+6.5)X5.5[/tex] sq cm

= 78.375 sq cm

So,

The area of the figure = 78.375×2 sq cm = 156.75 sq cm

Final answer:

Every natural number is a rational number and a real number, but not every rational or real number is a natural number. Also, all irrational numbers are indeed real numbers.

Explanation:

Let's address the statements about numbers and their classifications to determine if they are true or false:

Every natural number is a rational number. - True

Every rational number is a natural number. - False, rational numbers include fractions and negative numbers which are not natural numbers.

Every natural number is a real number. - TrueEvery real number is a natural number. - False, real numbers include rational and irrational numbers, so not all are natural.All irrational numbers are real numbers. - True

The corrected statements are:

Some rational numbers are not natural numbers; they can be fractions or negative numbers.Not all real numbers are natural numbers; real numbers encompass both rational and irrational numbers, whereas natural numbers are only the positive integers (1, 2, 3, ...).

How do you graph y=4x-3

Answers

In this problem, you would start by putting a point on(0,-3) because -3 is the y-intercept(b) in the equation y=mx+b. Next, you would plot the next point 4 units up and to the right once because 4/1 is aka rise/run and equal to m in the equation. Then you would keep going until you run out of room, then you would go the opposite way to create a line. I hope this helped:)

What is a graph?

A graph contains data of which input maps to which output.

Analysis of this leads to the relations which were used to make it.

If we know that the function crosses x-axis at some point, then for some polynomial functions, we have those as roots of the polynomial.

The function is given as y=4x-3

Here the point (0,-3) lies on the line because -3 is the y-intercept(b) in the equation y=mx+b.

What value does the red dot represent on the number line?

Answers

The red dot on the number line represents the value [tex]\(\frac{4}{5}\)[/tex], corresponding to option C.

In a fraction, the numerator (4) denotes the number of parts considered, while the denominator (5) indicates the total number of equal parts in one whole.

Thus, [tex]\(\frac{4}{5}\)[/tex] signifies four parts out of five, placing the red dot closer to the whole number 1 but not reaching it.

This representation aligns with the fraction's numerical value, emphasizing the position of the red dot on the number line and its fractional significance in relation to the unit interval.

Hence, the correct answer is Option C. 4/5

Final answer:

Determining the value of the red dot requires analyzing its position on the number line relative to specific landmarks and measurements provided; however, without the visual of the number line, a precise answer cannot be given.

Explanation:

The value of the red dot on the number line can be determined based on its position relative to the given reference points. The various descriptions of dots' positions involve a comparison to Car X and Car Y figures, as well as precise measurements in terms of perpendicular hash marks on a graph. To ascertain the value that the red dot represents, we must closely examine its placement on the number line in comparison to these references. However, it's crucial to have a visual representation of the number line to provide an accurate value. The mentioned descriptions such as 'the third dot is about one and two-thirds perpendicular hash marks to the right of the center top perpendicular hash mark' indicate the need to understand measuring units and relative positioning on the number line.

according to a recipe, 9/20 oz, of sugar is needed to make 6 cookies. Ashley decided to use only a third of the sugar to make it healthier. how much sugar did Ashley use?

Answers

Answer:

The amount of sugar actually used by Ashley to bake 6 cookies is 0.15 oz

Step-by-step explanation:

The amount of sugar needed to make 6 cookies = (9/20)  oz

So, the total amount of sugar to be used = (9/20) oz

Let us assume the sugar actually used by Ashley = M oz

Also, given:

Sugar Used  = One third of SUGAR NEEDED

[tex]\implies M = (\frac{1}{3}) \times (\frac{9}{20})[/tex]

            = [tex](\frac{3}{20} )[/tex] = 0.15 oz

or M = 0.15 oz

Hence, the amount of sugar actually used by Ashley to bake 6 cookies is 0.15 oz.

Answer:

Step-by-step explanation:

The 4 stays the same because its the denominater.

After using some of her ribbon for a project and a bow, Jenna has 1 meter of ribbon left on the spool.

Jenna has a spool that contains 5 and 3/4 meters of ribbon. She uses 3 and 2/4 meters for a school project and 1 and 1/4 meters for a bow. To find out how much ribbon remains on the spool, we need to subtract the total amount of ribbon used from the initial amount.

First, let's simplify the fractions. 3 and 2/4 meters can be simplified to 3 and 1/2 meters because 2/4 is equivalent to 1/2.

Next, we add the lengths of ribbon used for the project and the bow together: 3 and 1/2 meters + 1 and 1/4 meters = 4 and 3/4 meters.

Finally, we subtract this amount from the total amount of ribbon Jenna had: 5 and 3/4 meters - 4 and 3/4 meters = 1 meter.

Therefore, after using ribbon for a school project and a bow, Jenna has 1 meter of ribbon left on the spool.

I'm a little confused about a math lesson about equations with variables on both sides. Could someone explain this to me.
Heres a random question: Solve for m 4m + 2(m + 1) = 9m + 5?

Answers

So basically what you’re trying to do is isolating the variable (in this case it’s “m”). First you should simply, in this case you would do distributive property on the left side. Then you would take all the variables to one side, by either subtracting them or adding them (subtract the smallest variable from its own side, then do the same thing on the other side). Then take the constants and put them both on one side (in this case i’m subtracting the five from both sides). Then isolate the variable by dividing the coefficient by everything.

Twice the number of a number 9 is 6

The image of (6, 9) under a dilation is (4, 6).

O 2/3
0 -2/3

Answers

The scale factor of the dilation is 2/3. This means that the image point is two-thirds the distance from the original point to the center of dilation.

To find the scale factor of the dilation, we can use the formula:

[tex]\[ \text{scale factor} = \frac{\text{image point}}{\text{original point}} \][/tex]

Given that the image of (6, 9) under the dilation is (4, 6), we can substitute these values into the formula:

[tex]\[ \text{scale factor} = \frac{(4, 6)}{(6, 9)} \]\[ \text{scale factor} = \left( \frac{4}{6}, \frac{6}{9} \right) \][/tex]

Simplifying the fractions:

[tex]\[ \text{scale factor} = \left( \frac{2}{3}, \frac{2}{3} \right) \][/tex]

B. The scale factor is 2/3

To determine the scale factor of the dilation, we need to compare the coordinates of the original point 6, 9 and its image 4 , 6

The formula for dilation of a point x, y by a scale factor k is:

[tex]\[(x', y') = (kx, ky)\][/tex]

Given:

- Original point 6 , 9

- Image point 4 , 6

We need to find the scale factor k such that:

[tex]\[4 = k * 6 \quad \text{and} \quad 6 = k * 9\][/tex]

Let's solve these equations.

1. 4 = 6k

[tex]\[k = \frac{4}{6} = \frac{2}{3}\][/tex]

2. 6 = 9k

[tex]\[k = \frac{6}{9} = \frac{2}{3}\][/tex]

Both equations give the same scale factor of 2/3.

Find g-1(x) when g(x)=3/5x-9

Answers

Answer:

[tex]g^{-1}[/tex](x) = [tex]\frac{5x+45}{3}[/tex]

Step-by-step explanation:

let y = g(x) and rearrange making x the subject

y = [tex]\frac{3}{5}[/tex] x - 9 ( add 9 to both sides )

y + 9 = [tex]\frac{3}{5}[/tex] x

Multiply both sides by 5 to clear the fraction

5y + 45 = 3x ( divide both sides by 3 )

[tex]\frac{5y+45}{3}[/tex] = x

Change y back into terms of x, thus

[tex]g^{-1}[/tex](x) = [tex]\frac{5x+45}{3}[/tex]

The inverse is g⁻¹(x) = (5/3)*(x + 9)

How to find the inverse?

for a function f(x), the inverse f⁻¹(x) is defined as:

if f(x) = y

f⁻¹(y) = x

For this case, we can write:

g(g⁻¹(x)) = x

(3/5)*g⁻¹(x) - 9 = x

(3/5)*g⁻¹(x) = x + 9

g⁻¹(x) = (5/3)*(x + 9)
