Whats The Equation For This Table?

Answers

Answer 1

Answer:

y=2.5x-3

Step-by-step explanation:

first, we find the y-intercept, which is the number with a zero in the x

That would be -3

next, we find the slope

to do this, we have to take two numbers on the y side next to each other and subtract.

For this example we will use 7 and 2

7-2=5

And just to be positive, we will also do 12 and 7

12-7=5

Okay, now that we know that the number is growing by 5 every time, we know that it is now 5/2 because y is growing by 5 and x is growing by 2

Now, we make the x side grow by only 1, so to do this, we will divide both sides by two.

Now we have 5/1 or just 5

Finally, to put that into the right format, we do y=5x-3

You're Welcome

Good Luck

21 square feet

Step-by-step explanation:

To find out the area of this irregular figure, divide it into two rectangles and add their areas.. This can be done in two ways.

Version 1: 6 * 2 rectangle and 3 * 3 square

(6 * 2) + (3 * 3)

12 + 9

21 sq. ft.

Version 2: 5 * 3 rectangle + 2 * 3 rectangle

(5 * 3) + (2 * 3)

You could really just do 7 * 3 here.

7 * 3

21 sq. ft.

Either way, you still get 21 square feet as your answer.

The current temperature is 48 degrees Fahrenheit it is expected to drop 1.5 degrees each hour. Determine in how many hours the temperature will be 36 degrees Fahrenheit.

Answers

The answer is that it would take 8 hours for the temperature to drop down to 36 degrees.

1.5x8=12

1x8=8 and 0.5x8=4

In 8 hours the temperature will be 36°F from 48°F.

What is an equation?

An equation is written in the form of variables and constants separated by the operation of multiplication and division,

An equation states that terms in different forms on both sides of the equality sign are equal.

Multiplication and division do not separate the terms of an equation.

Given, The current temperature is 48 degrees Fahrenheit it is expected to drop 1.5 degrees each hour.

Assuming the no. of hours to be x.

∴ 36 = 48 - 1.5x.

- 1.5x = - 12.

x = 8.

Answers

Answer:

∠ VXW = 69°

Step-by-step explanation:

The inscribed angle VXW is half the measure of its intercepted arc VW

arc VW = 360° - (116 + 106)° = 360° - 222° = 138°, then

∠ VXW = 0.5 × 138° = 69°

What is the volume of the following triangular prism?
4.5 cm
12 mm
7 cm
3.5 cm 3
18.9 cm 3
12 cm
13
37.8 cm 3

Answers

Answer:

Step-by-step explanation:

In order to calculate the volume of a triangular prism you need 2 things:

The triangles area and the prism's height.

Any prism's volume can be calculated by multiplying its base area with its height.

The Area of a triangle can be calculated in different ways.

The most used and "normal" way is:

(width * height) / 2

Another way is by using herons formula, which looks like this:

a, b, c = different sides of the triangle (length)

s = (a + b + c) / 2

a = [tex]\sqrt{s (s-a)(s-b)(s-c)}[/tex]

When you have the prism's base area ([tex]b_{a}[/tex]) you just have to multiply:

[tex]b_{a}*h=V[/tex]

(V = volume)

The diagram shows a regular 11-sided polygon.
Work out the size of the angle marked d.
Leave answer to 2 decimal places where appropriate.

Answers

Answer:

d = 32.73°

Step-by-step explanation:

Angle 'd' is an exterior angle of the given polygon.

By the property of the exterior angles of a polygon, sum of exterior angles of a polygon is 360°.

And the measure of an exterior angle of a polygon = [tex]\frac{360}{n}[/tex]

Here 'n' = Number of sides of the polygon

From the picture attached,

Number of exterior angles of the regular polygon = 11

Therefore, measure of the exterior angle = [tex]\frac{360}{11}[/tex]

                                                                    = 32.7272

                                                                    ≈ 32.73°

299 x 0.85 = 254.15

Tax Rate- 5.5% = 0.055

254.15 x 0.055 = 13.97825

13.97825 + 254.15 = 268.13
