Tables are told used to arrange ungrouped data.

From the given table, we can find the equation by using the coordinate points (1, 80) and (1, 160)

Find the equation of the line

The standard equation of a line is y = mx + b

m is the slope

b is the y-intercept

Slop = 160-80/2-1

Slope = 80

For the y-intercept

160 = 80(2) + b

b = 0

The required equation is y = 80x

what is the measure of angle F????

Answers

Answer:

Angel F would equal about 50 degrees.
I used my protractor to measure the angle. My answer may be incorrect since I measuring it through a computer screen. (please read more before submitting your answer)

Another strategy:
(this one should be more accurate)
The sum of exterior angles in a polygon is always equal to 360 degrees. Therefore, for all equiangular polygons, the measure of one exterior angle is equal to 360 divided by the number of sides in the polygon.

The angles are given all equal 312 degrees
75 + 91 + 146 = 312 degrees

This means angel F equals:
360 degrees - 312 degrees = F degrees

F = 48 degrees

In conclusion, 48 and 50 are reasonable answers but the strategy used to find the answer 48 degrees makes more sense.

Jay is measuring the angles of a triangle. He gets 30 degrees and 100 degrees, what is the measured third angle?

Answers

Answer:

50°

Step-by-step explanation:

the sum of the 3 angles in a triangle = 180° , that is

3rd + 30° + 100° = 180°

3rd + 130° = 180° ( subtract 130° from both sides )

3rd angle = 50°

Answer:

50 degrees

Step-by-step explanation:

In any triangle, there are 180 degrees. If we add 100 degrees plus 30 degrees to get 130, simply subtract that from 180 the get the measure of the third angle. (180-130= 50) Hope this helps!

Key ConceptsConverting between cm³ and mL1 cm³ = 1 mLFinding the volume of rectangular prisms

To find the volume of a rectangular prism, we can use the following formula:

[tex]V=lwh[/tex]

l = lengthw = widthh = height

Converting between mL and L

1000 mL = 1 L

Solving the Question

We're given:

Fish tank measurements: 75 cm by 45 cm by 35 cmJug capacity = 1.75 L

To solve this question, we could follow these steps:

Find the volume of the tankDivide the volume of the tank by the jug capacity

Find the volume of the tank

[tex]V=lwh[/tex]

⇒ Plug in the measurements: 75 cm by 45 cm by 35 cm
[tex]V=75*45*35\\V=118125[/tex]

Therefore, the volume of the tank is 118125 cm³.

Divide the volume of the tank by the capacity of the jug

There is a relationship between cm³ and mL, not cm³ and L. Convert the 1.75 L for the jug capacity to mL:

1.75 × 1000

= 1750

118125 ÷ 1750

= 67.5

Answer

It takes 68 full jugs of water to fill the tank.

Shane went bowling with his friends. The bowling alley charges $20 for an hour of group bowling plus a fee to rent each pair of shoes. Shane's group bowled for one hour, rented 4 pairs of shoes, and paid a total of $31. Which equation can you use to find the fee, x, to rent each pair of shoes?

Answers

Answer:

4x+20=31

Step-by-step explanation:

So one hour of bowling is 20 dollars and they bowled for one hour hence the 1x20 which is equal to 20. That is the base coast we add to the variable of x that is the cost of renting one pair of shoes. And since they rented 4 pairs of shoes you multiply x by 4 to get 4x. Add the 20 dollars they paid to bowl and it is 4x+20. They paid 31 dollars in total so equal the equation to 31. 4x+20=31. Solution is $2.75 per pair of shoes.

What is the simplified expression of (4-5r+8s)(5r-9)

Answers

Answer:

The simplified expression of (4-5r+8s)(5r-9) is

40r s-25r^2-72s+65r-36

(hope this helped)

The simplified expression of (4-5r+8s)(5r-9) is [tex]65r - 25r^2 + 9r + 40rs - 72s.[/tex]

The simplified expression of (4-5r+8s)(5r-9) step by step.

Understanding how to simplify expressions can be incredibly useful in algebra and will make solving equations much easier. By using the distributive property, we can multiply the terms inside the parentheses and then combine like terms to get the simplified expression.

To simplify the expression (4-5r+8s)(5r-9), we'll use the distributive property, also known as the FOIL method (First, Outer, Inner, Last). This property allows us to multiply each term in the first parentheses by each term in the second parentheses.

1. First, we multiply the term "4" in the first parentheses by each term in the second parentheses:

4 * 5r = 20r

4 * (-9) = -36

2. Next, we move to the second term in the first parentheses, "-5r," and multiply it by each term in the second parentheses:

-5r * 5r = -25r²

-5r * (-9) = 45r

3. Lastly, we move to the third term in the first parentheses, "8s," and multiply it by each term in the second parentheses:

8s * 5r = 40rs

8s * (-9) = -72s

Now, we have all the resulting terms:

20r - 36 - 25r² + 45r + 40rs - 72s.

To simplify further, we combine like terms. Like terms have the same variable(s) raised to the same power:

20r + 45r = 65r

-36 + 45r = 9r

So, the simplified expression is:

65r - 25r² + 9r + 40rs - 72s.

In mathematical terms, we applied the distributive property to multiply each term in the first parentheses by each term in the second parentheses. Then, we combined like terms to obtain the final simplified expression, 65r - 25r² + 9r + 40rs - 72s.

How ?

{

proof :

As three angles are given 90° So third angle will also be 90°

Reason:

→ Sum of interior angles = 2 (no. of angles - 2 × 180°

→Sum of interior angles = (4-2 × 180°)

→Sum of interior angles = (2 × 180°)

→Sum of interior angles = 360°

}

✿Now let the left angle be x

90° +90° + 90° + x = 360° 180° + 90° + x = 360°270° + x = 360x = 360° - 270°x = 90°

you can "go" from x to y and from y to x consistently and without any interruptions by applying that constant factor.

that makes it a linear relationship (a line on a chart, hence the name).

proportional relationships are relationships between two variables where their ratios are equivalent. another way to think about them is that, in a proportional relationship, one variable is always a constant value times the other. That constant is know as the "constant of proportionality".
