Given:

[tex]L=2\dfrac{1}{2}[/tex] ft and [tex]W=3\dfrac{2}{5}[/tex] ft.

[tex]P=2L+2W[/tex]

To find:

The value of P.

Solution:

We have,

[tex]P=2L+2W[/tex]

Substituting [tex]L=2\dfrac{1}{2}[/tex] and [tex]W=3\dfrac{2}{5}[/tex], we get

[tex]P=2\times 2\dfrac{1}{2}+2\times 3\dfrac{2}{5}[/tex]

[tex]P=2\times \dfrac{2(2)+1}{2}+2\times \dfrac{3(5)+2}{5}[/tex]

[tex]P=2\times \dfrac{5}{2}+2\times \dfrac{17}{5}[/tex]

[tex]P=5+\dfrac{34}{5}[/tex]

Taking LCM, we get

[tex]P=\dfrac{5(5)+34}{5}[/tex]

[tex]P=\dfrac{25+34}{5}[/tex]

[tex]P=\dfrac{59}{5}[/tex]

[tex]P=11\dfrac{4}{5}[/tex]

Therefore, the value of P is [tex]11\dfrac{4}{5}[/tex] ft.

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.

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.

Answer:

4 hours

Step-by-step explanation:

It takes one hour to make one cake, so we can put that as a ratio of 1:1.

4 cakes means you multiplied one side by 4, as it is 4 cakes and not one, so you multiply the time by 4 too.

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:

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

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

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

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.

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:

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.
