Answer:

x = 14

Step-by-step explanation:

We can calculate the value of x using similarity ratio

22/4 = x/3 cross multiply expressions

66 = 4x divide both sides by 4

x = 14

Answer:

Richard gets: £9

Andrew gets: £21

Step-by-step explanation:

To get the value of 1 part we have to add the total number of parts (3+7) and then divide them by the sum (30) 30/10 = 3 so we know 1 part is £3

Thus Richard gets: £3*3 = £9

And Andrew gets: £3*7 = £21

Answer:

Yes, your answer is correct.

Answer:

The domain of a function f(x) is the set of all values for which the function is defined, and the range of the function is the set of all values that f takes. (In grammar school, you probably called the domain the replacement set and the range the solution set.

Answer:

X=1÷2,Y=32°

Step-by-step explanation:

<R+<T<S=180(INTERIOR ANGLE OF TRAINGLE)

Y-2+90+60=180(S=60°BEING ONE ANGLE OF EQUILATERAL TRAINGLE)

Answer:

nope

Step-by-step explanation:

The given ratios  5:3 and 6:4 are not equivalent.

Equivalent ratios are the ratios that are the same when we compare them. Example 1/2 and 2/4 are equivalent ratios.

Two or more ratios can be compared with each other to check whether they are equivalent or not.

The given two ratios are 5:3 and 6:4

We can write them as 5/3 and 6/4

Let us apply subtraction, if we get 0 then these are equivalent.

6/4-5/3

The LCM of 4 and 3 is 12

=(18-20)/12

The value of 18-20 is -2

=-2/12

We have to divide 2 by 12 we get -1/6.

=-1/6 not equal to 0

Step-by-step explanation:

====================================================

Explanation:

The hexagon is broken up into 6 congruent or identical equilateral triangles. If we find the area of one triangle, then we multiply by 6 to get the area of the hexagon.

Going in reverse, we divide the hexagon's area by 6 to get the area of one equilateral triangle

We're told the hexagon has an area of [tex]18\sqrt{3}[/tex] square inches. Divide this by 6 and you should get the result [tex]3\sqrt{3}[/tex]. So each of the six equilateral triangles has area of [tex]3\sqrt{3}[/tex] square inches.

-------------------------------------

Each triangle has a base of [tex]2(\sqrt{3})^{x/12}[/tex] and a height of [tex](\sqrt{3})^{x/6}[/tex]

The x/12 and x/6 are exponents.

Let [tex]b = 2(\sqrt{3})^{x/12}[/tex] and [tex]h = (\sqrt{3})^{x/6}[/tex] be the base and height respectively.

Also, let [tex]A = 3\sqrt{3}[/tex] be the area of the triangle

We can then solve for x like so:

[tex]A = 0.5*b*h\\\\3\sqrt{3} = 0.5*2(\sqrt{3})^{x/12}*(\sqrt{3})^{x/6}\\\\3*3^{1/2} = (\sqrt{3})^{x/12+x/6}\\\\3^1*3^{1/2} = (\sqrt{3})^{x/12+2x/12}\\\\3^{1+1/2} = (\sqrt{3})^{3x/12}\\\\3^{3/2} = (3^{1/2})^{x/4}\\\\3^{3/2} = 3^{(1/2)*(x/4)}\\\\3^{3/2} = 3^{x/8}\\\\[/tex]

Since the bases are equal to 3, this means the exponents must be equal as well (for both sides overall to be equal)

3/2 = x/8

3*8 = 2*x ... cross multiply

24 = 2x

2x = 24

x = 24/2

x = 12

Answer:

B

Step-by-step explanation:

There are a couple of ways you can go about solving this. The first is plotting all of the points and seeing which one makes a straight line. This is a little bit more time consuming but is great if you blank out and forget how to solve it. The faster way to do it is to see which function is decreasing/increase a constant amount between equal intervals. A increases but by a different amount each time. B decreases by 2 each time. C decreases at different intervals each time. And D does not consistently increase or decrease.

Step-by-step explanation: because when ur graphing the inequality the variable is on the opposite side

Answer:

Please check the explanation.

Step-by-step explanation:

Given

We can determine the area of the rectangular field using the equation

[tex]A=wl[/tex]

where

substituting  l = 240m, and  w = 200m in the formula

[tex]A=wl[/tex]

A = 240 × 200

A = 48000 m²

Given that the cost of digging the field at Rs 10 per m².

Thus,

The cost of digging the field of the area 48000 m² = 10 × 48000

                                                                                     = 480000 Rs

Therefore, the total cost of digging = 480000 Rs

Answer:

The arrow can be broken into a rectangle and a triangle.

And the area of the arrow is 22 ft^2

Step-by-step explanation:

Area of the rectangle:

length • width = 7 • 2 = 14 ft^2

Area of the triangle:

(base • height) / 2

You must add 1 + 2 + 1 in order to get the base which is 4

And to get the height, you must do 11 - 7 = 4 (height)

(4 • 4) / 2 = 8 ft^2

Add both areas together to get the area of the arrow:

14 ft^2 + 8 ft^2 = 22 ft^2

Answer:

The equation is;

y = -2x + 1

the answer belonging in the green question mark is -2

Step-by-step explanation:

We start by getting the slope

The slope can be obtained by selecting any two points and applying the slope formula

let us select the points;

(1,-1) and (3,-5)

the slope formula is;

m = (y2-y1)/(x2-x1)

m = (-5-(-1)/(3-1)

m = (-5+1)/2 = -4/2 = -2

The y intercept is the value of y when x = 0

As it can be seen, y = 1 when x = 0

so the equation of the relation is;

y = -2x + 1
