Answer:

You add similar  fraction by adding the numerators together but since the denominators are the same u keep them as they are

1. Similar fractions are those which have the same denominator. To change dissimilar fraction to similar fractions, you express them as a equivalent with a common denominator. For example 2/12, 3/12

2. To add similar fraction one should ensure that both the numerator are same and then add the numerator and put that on the denominator. If there is need to simply the fraction then you should first simplify the fraction.

For example:- 1/4+4/4= 5/4

Here as we see that bot number denominator are same so it's addition is done easily

The value of the sine of ∠F to the nearest hundredth is 0.72

A triangle is a figure that has 3 sides and angles. Given the following parameters;

∠H=90°

GF = 29

FH = 20

HG = 21.

Using the SOH CAH TOA identity;

sin theta = opposite/hypotenuse

sin ∠F = HG/GF

Substitute the given parameters

sin ∠F= 21/29

sin ∠F = 0.72

This gives the required value of sin ∠F to the nearest hundredth

Step-by-step explanation: add a zero and a point to the right f it

I don't know what the dropdown menus are, but Mike is half-correct. The opposite of a number is the number with the opposite sign, so the opposite of 5 is -5. But the absolute value of a number is its distance from zero on a number line, and distances can't be negative, so the absolute value of 5 is 5, not -5.

The system of inequalities that models the situation is given as follows:

Before we build the inequalities, we have to consider that the variables of the system are given as follows:

Jeremy and his dad worked at least 85 combined hours last week, hence the first inequality is:

x + y ≥ 85.

They collected a total of more than $1000 by charging $20 per hour, hence the second inequality is:

20x + 20y ≥ 1000.

20(x + y) ≥ 1000.

The minimum number of hours that each can work is of 0, that is, they cannot work a negative number of hours, hence the constraints are:

Answer:

x = 37 , ∠ P = 17° , ∠ Q = 126° , ∠ R = 37°

Step-by-step explanation:

the sum of the 3 angles in Δ PQR = 180°

sum the 3 angles and equate to 180

x + x - 20 + 3x + 15 = 180

5x - 5 = 180 ( add 5 to both sides )

5x = 185 ( divide both sides by 5 )

x = 37

Then

∠ P = x - 20 = 37 - 20 = 17°

∠ Q = 3x + 15 = 3(37) + 15 = 111 + 15 = 126°

∠ R = x = 37°

Answer:

Well, if we consider [tex]r[/tex] as y and [tex]q[/tex] as x.

Step-by-step explanation:

So, typically, a linear function is either represented using function notation

[tex]f(x)=mx+b[/tex]

Or in slope-intercept form

[tex]y=mx+b[/tex]

This question is oddly using the variables r and q in place of y and x. If we replace them to be y and x, it will be a linear equation (because the slope is constantly changing).

But, if you aren't allowed to replace r and q to be y and x, then it isn't a linear function.

The simplified solution for B in the equation -4 ( - 6 - b) = 1/3 (B + 16) is B = 56 + 12b

Given,

The equation: - 4 (- 6 - b) = 1/3 (B + 16)

We have to simplify the equation and find B.

Lets simplify:

-4 ( - 6 - b) = 1/3 (B + 16)

Here,

(- 4 × - 6) - 4 × - b = 1/3 × B + 1/3 × 16

24 + 4b = B/3 + 16/3

24 + 4b = (16 + B) / 3

Multiply 3 to both sides:

(24 + 4b) × 3 = (16 + B) × 3 / 3

72 + 12b = 16 + B

Add -16 to both sides:

72 + 12b - 16 = 16 + B - 16

Then,

B = 72 + 12b - 16

B = 56 + 12b

That is, the simplified solution for B in the equation -4 ( - 6 - b) = 1/3 (B + 16) is B = 56 + 12b

Answer:

the top right graph

Step-by-step explanation:

I assume you mean the function is

f(x) = sqrt(x + 4) - 2

because for your function as you wrote it

f(x) = sqrt(x) + 4 - 2 = sqrt(x) + 2

none of the graphs apply.

to find the correct one we look at some specific points.

like x = 0, and when the square root will be 0 (x = -4).

normally we can see the right graph latest here already, but if not, then we have to pick a few more points.

so,

for x = 0 we get

sqrt(0 + 4) - 2 = 2 - 2 = 0

that means

f(0) = 0

now, when we look at the graphs, we see we are already finished. there is only one graph that goes through (0, 0).

the top right graph.

Interpolation is the process of foretelling the value of a function f at a location inside the observed range of values for and. Predicting the value of y when it is outside the range indicated by the points and areas where the values and have been observed is known as extrapolation.

The values for two different numerical variables are represented by dots in a scatter plot (also known as a scatter chart or scatter graph). Each dot's location on the horizontal and vertical axes represents a data point's values. To view relationships between variables, utilize scatter plots.

A polygon with the three edges and three vertices is called a triangle. It is one of fundamental geometric shapes. The symbol for a triangle containing the vertices A, B, and C is ABC.

In Euclidean geometry, any three points that are not collinear produce a singular triangle and a singular plane (i.e. a two-dimensional Euclidean space). In other words, every triangle is contained in a plane, and there is only one plane that contains that triangle. All the triangles are enclosed in a single plane if all of geometry is the Euclidean plane, however this is no longer true in higher-dimensional Euclidean spaces. Except when otherwise specified, this article discusses the triangles in Euclidean geometry, namely the Euclidean plane.

Which is the smallest angle, which is the right angle, and which is the third angle of the triangle are the three inner angles (A, B, C) of a right angled triangle.

sum of the interior angles of a triangle = 180

ratio 7:18:11

so

7+18+11 = 36

180 / 36 = 5

7 x 5 = 35

18 x 5 = 90

The coordinates of the point of intersection is equal to (3, 5).

In Mathematics, a point of intersection can be defined as the location on a graph where two (2) lines intersect, meet, or cross each other, which is typically represented as an ordered pair containing the point, x-axis and y-axis.

Next, we would solve the given equations simultaneously to determine the coordinates of the point of intersection as follows:

y = 1 - 2x

y = x - 5

Re-arranging the equation, we have:

y + 2x = 1

y - x = -5

Subtracting, we have:

3x = 6

x = 6/2

x = 3.

For y-coordinate, we have:

y + 2x = 1

y + 2(3) = 1

y + 6 = 1

y = 1 - 6

y = -5.

This ultimately implies that, a number line can be used to determine the difference between two numbers such as 4 and 1. Also, a number line typically increases in numerical value towards the right and decreases in numerical value towards the left.
