Find the value of x.
x= 2.
x= 3
x= 33
x= 52

Answers

Answer 1

Answer: x=2

57+x=25x

subtract x from both sides

57+x-x=25x-x

57=24x

divide by 24 on both sides

57÷24=24x÷24

x=2.375

The sum of the interior angle of a triangle is equal to the exterior. . The value of x from the given figure is 3

Angles in a triangle

The sum of the interior angle of a triangle is equal to the exterior. According to the given figure;

25x + 57 +x = 45x

26x + 57 = 45x

Subtract 57 from both sides

26x -45x = -57

-19x = 57

x = 57/19

x = 3

Hence the value of x from the given figure is 3

The dimensions of the park are obtained as 180 yards and 140yards respectively.

What is a Linear equation?

A linear equation is a equation that has degree as one.

To find the solution of n unknown quantities n number of equations with n number of variables are required.

Suppose the width of the rectangle be x yards.

Then, its length is given as x - 40 yards.

Since, the perimeter of a rectangle is given as 2(l + b).

Substitute the corresponding values to get the equation as follows,

640 = 2(x - 40 + x)

=> 640 = 2(2x - 40)

=> 2x - 40 = 640/2

=> 2x - 40 = 320

=> x = 360/2 = 180

Then, the length is given as 180 - 40 = 140 yards.

Hence, the dimensions of the park are obtained as 180 yards and 140 yards respectively.

Jada fills the bathtub before taking a bath and then allows the water to drain when she is done. The graph below models the number of gallons of water, y, in the bathtub over time, t, in minutes. (look at graph)

Is the number of gallons of water in the bathtub a function of time?

A)Yes because each t value is paired with exactly one number of gallons.
B)Yes because the number of gallons is bounded between y = 0 and y = 36.
C)No because each number of gallons is paired with more than one t value.
D)No because from t = 5 to t = 20 the number of gallons of water is constant.

Answers

A.Yes because each t value is paired with exactly one number of gallons.

Step-by-step explanation:

Yes the number of gallons of water in the bathtub a function of time because each t value is paired with exactly one number of gallons.

Option A

Given :

The graph below models the number of gallons of water, y, in the bathtub over time, t, in minutes.

The number of gallons of water in bathtub depends on the time taken to fill or drain water

For each minutes in x there is one y value

There is no break in the graph . For each x value there is only one value

From this graph we can say that , for each t value (minutes) there is exactly one number of gallons (y value )

So, yes because each t value is paired with exactly one number of gallons.

The constant of proportionality is 1.25

For example, if number of candy bars is 10, find the price

n = 10

p = 1.25n

= 1.25 * 10

LuAnn is playing a math game. She chooses three cards. The value of each of her cards is shown. • First card: -12 • Second card: 3 • Third card: -5 What is the sum of the values of LuAnn's three cards?

Answers

The sum of all the cards of Luann is -14.

One of the four fundamental operations for arithmetic on integers, decimals, fractions, real and complex numbers, as well as in algebraic expressions or on structures related to them, including vector spaces, is sum (also known as addition).

The terms, addends, or summands collectively refer to the numbers or objects that need to be added in general addition; this nomenclature also applies to the summation of several terms. This should be distinguished from multiplied factors.Addition or sum follows the commutative , associative and distributive properties.

The given numbers on the cards are given as - 12 , 3 and - 5 .

Therefore the addition or sum is equal to :

-12 + 3 + ( - 5 ) = - 17 + 3 = - 14

Hence the sum of all the cards in LuAnn's card games is -14.

(8x-3y)(8x+3y) solve the following Can someone please help Find the measure of the bolded arc. Round to the nearest hundreth. Environmental scientists are often interested in evaluating both species richness and species evenness, so they have come up with milesspecies diversity that take both measures into account. One commonly used index is Shannon's index of biodiversity. To calculate this index,we must know the total number of species in the community (s) and, for each species, the proportion of the individuals in the community thatrepresents that species (p). Once we have the information, we can calculate Shannon's index of diversity (H) by taking the product of eachproportion (0) and its natural log (In ()) and then summing these products, as indicated by the summation symbol (E):H-- pin(p)whereH = the Shannon index valueP, = the proportion of individuals found in the ith speciesIn = the natural logarithmS = the number of species in the communityThe minus sign makes the index a positive number. Higher values of Hindicate higher diversityNote: the book uses "n" and the formula I found online uses "s" for the number of species in the community.Imagine a community of 100 individuals that are evenly divided among four species, so that the proportions () of the species all equal 0.25.We can calculate Shannon's index as follows: H = -((0.25 x In 0.25) + (0.25 x In 0.25) + (0.25 x In 0.25) + (0.25 x in 0.25)] H-[(-0.35)+(-0.35) + (-0.35) + (-0.35)] 1.40Now imagine another community of 100 individuals that also contains four species, but in which one species is represented by 94 indiviudalsand the other three species are each represented by 2 indivudals. We can calculate Shannon's index to see how this difference in speciesevenness affects the value of the index: H = -[(0.94 x in 0.94)+ (0.02 x In 0.02) + (0.02 x In 0.02) + (0.02 x in 0.02)] H=-[(-0.06) + (-0.08) + (-0.08) + (-0.08)] 0.30Because this value of His lower than the value we calculated for the first community, we can conclude that the second community has lowerdiversity. Note that the total number of indiiduals does not affect Shannon's index of diversity, only the the number of species and theproportion of individual within each species matters.Your TurnImagine a third community of 100 individual in which those indviduals are distributed evenly among all the species, but there are only twospecies, not four. Calculate shannon's index to see how different in species richness affects the value of the indexShannon's index.HeKif the answer is less than tha Zero belongs in front of the decimall What is the goal of forensic photography?
