Step-by-step explanation:

hello! i'm assuming you need to find the area, so you would need to multiply 20 and 12. Hope this helped and have a nice day/night!

A rectangle is a two-dimensional shape where the length and width are different.

The area of a rectangle is given as:

Area = Length x width

The area of the living room wall = The area of the rectangle

The amount of paint needed to cover one wall is 240 square feet.

A rectangle is a two-dimensional shape where the length and width are different.

The area of a rectangle is given as:

Area = Length x width

Example:

The area of a rectangle with length 2cm and width 3cm is 6cm².

We have,

A living room wall is 20 feet long, and 12 feet high.

The living room can be considered a rectangle.

Length = 20 feet

Width = 12 feet

The area of the living room wall = Area of a rectangle

Now,

Area of the living room wall.

= 20 x 12

= 240 square feet

Thus,

The amount of paint needed to cover one wall is 240 square feet.

Answer:

8x=32

Step-by-step explanation:

Answer:

16 is the equivalent to 32

Answer:

7.25

Step-by-step explanation:

Given :

___________ Sample size __ sample mean

Treatment 1 ____ 5 _______ 4

Treatment 2 ____ 10 ______ 8

Treatment 3 ____ 5 _______ 9

Sample size = (5 + 10 + 5). = 20

Overall mean = ((5*4). + (10*8) + (5*9)) / 20

Overall mean = (20 + 80 + 45) / 20

= 145 / 20

= 7.25

Write the values in the order shown. The curly braces indicate a set.

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

Explanation:

The replacement set for the independent variable is {2,4,6,8}

This means we'll plug x = 2, x = 4, x = 6, and x = 8 into the function one at a time to find the corresponding y = f(x) value.

---------

Plug in x = 2 to find that,

f(x) = 2x+3

f(2) = 2*2+3 ... replace every x with 2

f(2) = 4+3

f(2) = 7

If the input is x = 2, then the output is y = 7. Therefore, the '2' in the domain corresponds to '7' in the range.

If you repeat those steps for x = 4, then you should find that f(4) = 11. Do the same thing for x = 6 and it should lead to y = 15. The last value in the range is y = 19 which corresponds to x = 8.

In short, the domain {2,4,6,8} corresponds to the range {7, 11, 15, 19}

Usually with sets, order doesn't matter. However, in this case, the order is important because we need to match the 2 with the 7, the 4 with the 11, etc.

Answer:

This is kinda hard to answer, but i'm going to say the answer might be 14 cm squared.

Step-by-step explanation:

I don't have much info, but I can say that the 7 cm side can be split into 2 lengths of 5 cm, and 2 cm.

Using this i can do 5 times 4 to get 20, but sense it's a triangle, the triangle would be half of a square making it 10 cm for the left part of the triangle.

Using the knowledge of the left triangle, I can do 2 times 4, which equals 8, half of 8 cm is 4 cm, and now i can do the equation of 10 cm plus 4 cm equals the answer of 14 cm squared.

Answer:

3/8 kg of tomatos

Step-by-step explanation:

1/4 * 2 = 2/8

2/8 + 3/8 = 5/8

1 - 5/8 = 3/8

The amount of tomatoes was left to the mother in kilograms will be 0.375 kilograms.

Algebra is the study of mathematical symbols, and the rule is the manipulation of those symbols.

Mother has 1 kg of tomatoes.

She gave 1/4 to aling nena and 3/8 to aling ana.

Then the amount of tomatoes was left to the mother in kilograms will be

Let x be the amount of tomatoes.

x = 1 - 1 × 1/4 - 1 × 3/8

x = 1 - 0.25 - 0.375

x = 1 - 0.625

x = 0.375 kilograms

Answer:

Get a ruler

Step-by-step explanation:

I can't really answer this because it's a measuring problem.

But I'll walk you through it.

First, grab your ruler. Once you have it, you're gonna measure the icon, so the  square picture. Make sure you measure it in centimeters (cm). Measure EACH side. Once you have the measurement of each sides, add them up to get your perimeter. The perimeter will always be length + width + length + width.

To find the area, take your length and your width and multiply them together.

For the second problem, you're going to take your measured side and multiply EACH of them by 2.5. The scale 1 cm = 2.5 mm means that for every represented centimeter in the image, the actual image is 2.5 mm. Once you have multiplied each sides by 2.5, you're going to repeat the steps above to get the perimeter and the area.

Step-by-step explanation:

142 + 56 = 198º

Complimentary  = 90º

Supplementary  = 180º

Neither

Answer:

Neither

Step-by-step explanation:

Complementary angle means they would add up to 90.

Supplementary angle means they would add up to 180.

142 + 56 = 198

It is neither because the angle does not equal 90 or 180.

Answer:

E

Step-by-step explanation:

Using Pythagoras' identity in the right triangle

y² = x² + 4²

y² = x² + 16 ( take the square root of both sides )

y = [tex]\sqrt{x^2+16}[/tex] → E

For Triangle FGH Value of y in terms of x will be [tex]\sqrt{x^2 + 16}[/tex] .

The Pythagorean Theorem demonstrates how the side lengths of a right triangle can be calculated from the sum of the areas of three intersecting squares. This theorem is a very helpful tool that serves as the foundation for more intricate trigonometry ideas like the Pythagorean theorem's opposite.

Given, For FGH shown in figure Hyppotaneus of the triangle is y meters, the base of the triangle is x meters and the height of the triangle is 4 meters. From Pythagorean theorem

y² = x² + 4²

y² = x² + 16

y = [tex]\sqrt{x^2 + 16}[/tex]

Therefore, the Value of y in terms of x for Triangle FGH will be [tex]\sqrt{x^2 + 16}[/tex].

Step-by-step explanation:

Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.

For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one is attached to the event. If it doesn't a value of zero is attached to the event.

probability of picking a white marble first = total number of white marbles / total number of marbles = 7/21

probability of picking a green marble second = total number of green marbles / total number of marbles = 10/20

Answer: They can form one triangle.

Step-by-step explanation: Since all triangle must have 180 degrees, there’s only one set of degrees that sum up to 180.

28+51+101=180

I’m sorry, but the feet/centimeters part you have to solve on your own. Remember, this is a learning community! No stress :) I can guarantee you won’t get it wrong though.

There’s many different triangles, and I’m sure from these feet/centimeters you can make at least one of the listed: Scalene (none of the sides are equal), isosceles (only 2 sides are equal) or equilateral triangle (all sides are equal). There’s also right triangles (which are triangles with one right angle also known as 90 degrees) that are either isosceles or scalene or both! Try your best and remember, no stress :)
