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.
What is a rectangle?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.

The measure of ∠BCF is 60°, and the measure of ∠FCG is 35°. Which equation can you use to find the measure of ∠BCG?
Answer:
x = ∠BCF+ ∠FCG
Step-by-step explanation:
According to the given measure, we can say that, line Fc bisects ∠BCF and ∠FCG and the sum of ∠BCF and ∠FCG is ∠BCG. Mathematically;
∠BCF+ ∠FCG = ∠BCG
Given
∠BCG = 60degrees
∠FCG = 35degrees
Let x be equal to ∠BCG
Hence the required equation will be;
∠BCF+ ∠FCG =x
Swap sides
x = ∠BCF+ ∠FCG

8 is LESS THAN 1/2x
so youd take those numbers and multiply by 1/2
C, B, and A are all under 8, so that would be wrong
when you multiply 1/2 with 17, you get 8.5 which is bigger than 8. then everything else above that is more than 8, therefore D is the right answer.

A box contains 21 marbles of the same size. 7 of the marbles are white, 4 are black, 10 are green. If two of the marbles are randomly selected from the box, what is the probability that the first marble is white and the second is green, given that the first marble is not replaced before the second marble is selected
Answer:
7/21 x 10/20
1/3 x 1/2 = 1/6
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
7/21 x 10/20
1/3 x 1/2 = 1/6

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.

Is this angle complementary or supplementary or neither?
Answer:
Neither
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.

Given the equation: I + I → I2 + 35 kcal This equation shows that the formation of an iodine molecule is an A) endothermic process in which energy is absorbed B) exothermic process in which energy is released C) exothermic process in which energy is absorbed D) endothermic process in which energy is released
Answer:
A) endothermic process in which energy is absorbed
Step-by-step explanation:
A thermochemical reaction equation is a chemical reaction equation in which the enthalpy of reaction is written after the symbols of reactants and products.
The importance of thermochemical reaction equations is that they show us whether energy was absorbed or evolved in a reaction as well as the magnitude of energy absorbed or evolved.
When the enthalpy of reaction is positive, the reaction is endothermic and energy is absorbed. When the enthalpy of reaction is negative, the reaction is exothermic and energy is evolved or released.
The enthalpy of the reaction I + I → I2 + 35 kcal is positive hence the reaction is an endothermic process in which energy is absorbed.
The equation shows that the formation of an iodine molecule is an A. endothermic process in which energy is absorbed.
What is an endothermic process?It should be noted that an endothermic process is where heat is transferred from the surroundings to the systems. In this case, the system has gained heat from the surroundings.
The change in enthalpy, delta H is positive for an endothermic process. When the enthalpy of reaction is positive, the reaction is endothermic and energy is absorbed. The enthalpy of the reaction is positive as illustrated in this case.

For FGH shown below, which of the following is an expression for y in terms of x?
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] .
What is the Pythagorean theorem?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].
