Answer:

55cm^2

Step-by-step explanation:

Split into 2 parts, the rectangle on the left, and triangle on the right.

Rectangle:

8 cm x 5 cm = 40 cm^2

Triangle

14 cm - 8 cm = 6cm (Height)

(5cm(base) x 6cm)/2 = 15cm ^2

15cm^2 + 40cm^2 = 55cm^2

Answer:

The bottle that costs R59,99 for 375 g is cheaper

Step-by-step explanation:

The given costs of the bottles of honey are given as follows;

The cost of one of the bottles of honey = R89,99 for 530 g

The cost of the other bottle of honey = R59,99 for 357 g

Let 'x' represents the bottle of honey that costs R89,99 and let 'y' represent the bottle of honey that costs R59,99, we have;

The unit cost (cost per gram) for the bottle of honey, 'x', C/gₓ = R89,99/(530 g) ≈ R 0.16979/g

The unit cost (cost per gram) for the bottle of honey, 'y', [tex]C/g_y[/tex] = R59,99/(357 g) ≈ R 0.168/g

Given that the unit cost of a bottle 'y' ≈ R 0.168/g is less than the unit cost of a bottle of 'x' ≈ R 016979/g, a bottle 'y' is cheaper than the bottle 'x'

Therefore;

The bottle that costs R59,99 for 375 g is cheaper than the bottle that costs R89,99 for 530 g.

Answer:

B

Step-by-step explanation:

This is a neat question

f(x) - g(x) = 2x           Add g(x) to both sides

f(x) = g(x) + 2x

Now you need the right hand side to have 20 added to g(x).

2x must = 20

2x = 20                    Divide by 2

x = 20/2

x = 10

So the answer must be x = 10

The slope of the line is 20.

The slope represents the rate of change in the price per hour is $20.

The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.

The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.

We have,

Two coordinates from the graph.

(1, 60) and (3, 100)

Slope.

= (100 - 60) / (3 - 1)

= 40 / 2

= 20

The slope represents the rate of change in the price per hour.

Thus,

The value of the slope is 20.

The slope denotes that the rate of charge per hour is $20.

Answer:

[tex]x \approx 55.8[/tex]

Step-by-step explanation:

In order to solve this problem, one must use the trigonometric ratios. These ratios are the following,

[tex]sin(\theta)=\frac{opposite}{hypotenuse}\\\\cos(\theta)= \frac{adjacent}{hypotenuse}\\\\tan(\theta)=\frac{opposite}{adjacent}[/tex]

Remember, each side is named relative to the angle, thus sides will attain different names depending on the angle which one sues to calculate with.

In this case, one is given the measure of the angle, and the measure of the side opposite to the angle. One is asked to find the measure of the side adjacent to the angle. Use the trigonometric ratio ([tex]tan[/tex]) to solve for the unknown. Substitute in the given values,

[tex]tan(25)=\frac{26}{x}[/tex]

Manipulate the equation such that it is solved for the parameter(x),

[tex]x=\frac{26}{tan(25)}[/tex]

Solve,

[tex]x \approx 55.8[/tex]

Answer:

(-1,0)

Step-by-step explanation:

To find the x value of the vertex use the equation

-b/(2a)

-4/(2*2)= -1

this means that the x coordinate is -1

Now that we know the x value we need to find the corresponding y value

to do this we just plug in x into the equation

2(-1)²+4(-1)+2

2-4+2=0

put it all together and get (-1,0)

y=-2x-5 and y=-7x+15.75 are equations in  slope-intercept form for each line.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

We need to find equation in slope-intercept form of line passing through of (-6,7) to (1,-7) and one more line passing through (1.25,7) to (3.25,-7)

Slope of line with (-6,7) to (1,-7) is m=-7-7/1+6=-14/7

=-2

y intercept we have to find

7=-2(-6)+b

7=12+b

-5=b

So slope intercept form of line passing through (-6,7) to (1,-7) is y=-2x-5

Now Slope of line with (1.25,7) to (3.25,-7) is

m=-7-7/3.25-1.25

m=-14/2=-7

y intercept we have to find

7=-7(1.25)+b

7=-8.75+b

b=15.75

So slope intercept form of line passing through (1.25,7) to (3.25,-7) is y=-7x+15.75

Hence, y=-2x-5 and y=-7x+15.75 are equations in  slope-intercept form for each line.

The fraction after solving and simplifying the mixed fraction 5 3/4 ÷ 1 1/2​ is 23 / 6.

A mixed fraction is a fraction that is created by fusing a fraction with a whole number. For instance, 8 1 / 2 is a mixed fraction if 8 is a whole number and 1/2 is a fraction.

Given:

5 3/4 ÷ 1 1/2​

Solve the mixed fraction into improper fractions as shown below,

5 × 4 + 3 / 4 ÷ 1 × 2 + 1 / 2

20 + 3 / 4 ÷ 2 + 1 / 2

23 / 4 ÷ 3 / 2

23 / 4 × 2 / 3

23 × 2 / 4 × 3

On simplifying,  

23 × 1 / 2 × 3

23 / 6

Those are vertical angles so both sides need to be equal.

2x+15 = 145

Subtract 15 from both sides:

2x = 130

Divide both sides by 2:

x = 65

Answer:

145 = 2x + 15

2x = 130

x = 65

145 and 2x + 15 are vertical angles and therefore congruent.

The polynomial in terms of its simplest factors is (x + 3)(x − 6)

From the question, we have the following parameters that can be used in our computation:

x2 − 3x − 18.

Rewrite as

x² − 3x − 18

Expand

x² − 3x − 18 = x² − 6x + 3x − 18

Factorize the expression

This gives

x² − 3x − 18 = x(x − 6) + 3(x − 6)

Factor out x - 6

x² − 3x − 18 = (x + 3)(x − 6)

Hence, the expression is (x + 3)(x − 6)

Answer:

x = - 2 or x = - 4

Step-by-step explanation:

Via completing the square:

x^2 + 6x + 8  = x^2 + 6x + (6/2)^2 - (6/2)^2 + 8

                     = (x + 3)^2 - 3^2 + 8

                     = (x + 3)^2 - 9 + 8

                     = (x + 3)^2 - 1

Since x^2+6x+8=0,

(x + 3)^2 - 1 = 0

(x + 3)^2 = 1

x + 3 = +- sqrt(1)

x + 3 = +- 1

x + 3 = 1 or x + 3 = -1

x = -2 or x = -4

The coordinate of 3 4 indicates a point on a cartesian plane.

In mathematics, the coordinate system refers to the method in which a location of a point is identified in the plane or space.

There are two coordinate system, one is cartesian coordinate system and the other is polar coordinate system.

Each coordinate system has some reference lines called reference axis or reference direction or point called reference direction and point.

As per the definition of a cartesian coordinate system, a location of a point is identified by a pair of numerical terms. The first one indicates the X coordinate and the second one indicates the Y coordinate.

So, the above coordinate 3 4 refers to a point on the XY coordinate system where 3 is the X coordinate and the distance from Y axis and 4 is the Y coordinate and distance from the X axis.

ordinate refers to y point in (x, y)

Answer:

68, 97, 81, 96, 84.2

Step-by-step explanation:

16. The minimum of the data is the smallest value. Take the smallest stem value and find its smallest leaf value, you'll get 68.

17. Take the largest stem value and find its largest leaf value. That's 97.

18. Counting the number of values, there are 10 values here. So you need to look at the mean of the 5th and 6th values. (80 + 82) ÷ 2 = 81

19. Mode: the most frequently occurring value. All values in this dataset are unique except for the two 96s in the last row, hence 96 is the mode.

20. Add all values and divide your result by the number of values.

(68+75+77+79+80+82+92+96+96+97) ÷ 10 = 84.2

Hence 84.2 is your mean.
