Which equation best represents the relationship between x and y in the graph? * 2 points

Answer: x=8 angle BDC=77

Step-by-step explanation:

9x-12x=-19-5

-3x=-24

x=8

12x(8)-19

=77

(9x + 5) and (12x - 19) are one angle split equally.

(9x + 5) = (12x - 19)

The value of m∠BDC is 65°

It is a two-dimensional figure which has three sides and the sum of the three angles are equal to 180 degrees.

We have,

(9x + 5) and (12x - 19) are one angle split equally.

So,

9x + 5 = 12x - 19

We will solve for x.

9x + 5 = 12x - 19

Add 19 on both sides.

9x + 5 + 19 = 12x

Subtract 9x on both sides.

24 = 12x - 9x

24 = 3x

Divide both sides by 3.

24/3 = x

x = 7

Now,

The value of m∠BDC.

= 12x - 19

= 12 x 7 - 19

= 84 - 19

= 65°

Thus,

The value of m∠BDC is 65°

Step-by-step explanation:

The parameters of the workers in the office are;

The number of staffs in the office = 60 staffs

The take-aways are pizza, curry, fish & chips, kebab and other

The frequency for the above take-aways = 14, 6, 4, 14, and 22 respectively

The variables for the angles representing the above take-aways on the pie chart = 'a', 'b', 'c', 'd', and 'e'; respectively

In order to find the size of the angles that represent each group of workers in the pie chart, we find the ratio of the group size to the total number of workers and we multiply the result by 360° as follows;

∠a = 360° × 14/60 = 84°

∠b = 360° × 6/60 = 36°

∠c = 360° × 4/60 = 24°

∠d = 360° × 14/60 = 84°

∠e = 360° × 22/60 = 132°

Answer:

Step-by-step explanation:

Step 1: Find out how many pens he bought

12 pens per pack

Charles bought 60 packs

60 packs x 12 pens = 720 pens

Step 2: Find out how much Charles spent

2.80 per pack

Charles bought 60 packs

60 x 2.80 = 168 pounds

Step 3: Find out how many pens Charles sold

Charles sold 2/3 of his pens

2/3 x 720 = 480

Step 4: Find out how manypens he sold

Charles sold the pens for 40p

40p x 480 = 19200p

Step 5: Convert pences to pounds

19200p = 192 pounds

Step 6: Find the profit

192 - 168 = 24 pounds

Step 7: Therefore statement

Therefore he mad 24 pounds of profit

Answer:

New power = 88 Kw (Approx.)

Step-by-step explanation:

Given:

P = a(v³)

Old power p = 700 Kw

Old wind speed v = 12 m/s

Find:

New power when v = 6m/s

Computation:

P = a(v³)

700 = a(12³)

a = 0.4050 m²

New power = a(v³)

New power = (0.4050)(6³)

New power = 87.48

New power = 88 Kw (Approx.)

Step-by-step explanation:

formula to find area of a triangle:

A=1/2 × base × height(h)

insert the values into the formula:

24=1/2 × 4 × h

solve for h :

24=2h

24/2=h

h = 12 cm ( Ans )

The height of triangle will be 12 cm.

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Given that;

The triangle has a base length of 4 cm.

And, A total area of 24 cm².

Now,

We know that;

Area of right triangle = 1/2 × Base × Height

⇒ 24 = 1/2 × 4 × h

⇒ 24 = 2 × h

⇒ h = 24 / 2

⇒ h = 12 cm

Thus, The height of triangle = 12 cm.

Answer:

16.5

Step-by-step explanation:

A is the correct answer

Step-by-step explanation:

If you plug y=x+10 in for the Y variable you just have to solve by multiplying.

1.) It should look like this:

2x + 3(x +10) = 40

2.) You will distribute the three which will make the equation look like this:

2x + 3x + 30 = 40

3.) Add like terms. Then subtract 30 from both sides. Then divide 5 by both sides to get the variable x alone.

but 16.5 is the answer

Answer: 4.8x+3

Step-by-step explanation:

The portion of the phone that is not occupied by the screen is 4.9x + 3 cm².

For each three-dimensional geometrical shape, surface area and volume are determined. The area or region that an object's surface occupies is known as its surface area. Volume, on the other hand, refers to how much room an object has. There are numerous shapes and dimensions in geometry, including sphere, cube, cuboid, cone, cylinder, etc. Each form has its own volume and surface area. Nevertheless, we can only estimate the area that two-dimensional figures like a square, circle, rectangle, triangle, etc. cover; there is no volume available.

As per the given data:

The width of the screen = x cm

Height of the screen = 1.9 times the width = 1.9x

Dimensions of the phone are given in the diagram.

The area of the screen = height × width

= 1.9x × x = 1.9x² cm²

The area of the phone = (1.9x + 3)(x + 1)

= 1.9x² + 1.9x + 3x + 3

= 1.9x² + 4.9x + 3 cm²

Area of the phone not occupied by screen:

= area of the phone - area of the screen

= 1.9x² + 4.9x + 3 - 1.9x²

= 4.9x + 3 cm²

Hence, the portion of the phone that is not occupied by the screen is 4.9x + 3 cm².
