Answer:

62feet

Step-by-step explanation:

10x=620

x=62feet

The perimeter usually gives the length of the figure. In a square, which has al its sides equal, the perimeter of the square will be four times its sides. The maximum width of the rectangle is 62 feet.

The perimeter of a rectangle is defined as the total distance covered by its boundaries or the sides. Since the rectangle is comprised of four sides, the perimeter will be the sum of all four sides. The perimeter is a linear measure and its unit is m, cm, feet, etc.

The equation used to calculate the perimeter of a rectangle is given as:

Perimeter = 2 (l + b)

Here l = length

b = breadth

Here the length is four times the width, l = 4x

Width may be b = x

Then perimeter is:

P = 2 (4x + x) = 620

10x = 620

x = 620 / 10 = 62 feet

Thus the width is 62 feet.

Answer:

  D.  A triangle with angles measuring 75°, 60°, and 45°​

Step-by-step explanation:

Given various triangle descriptions, you want to know which one describes more than one triangle.

The angles and sides of a triangle satisfy a few different relations:

A. Two sides and the included angle can be used with the Law of Cosines to find the length of the third side. That is, a single triangle is created by these measurements.

B. Sides measuring 4, 8, and 15 do not satisfy the triangle inequality, so no triangle is created by these measurements.

C. Sides measuring 6, 8, and 10 satisfy the triangle inequality, so will create a single triangle. (That triangle is a right triangle.)

D. The given angles total 180°, so could be the angle measures of any number of triangles. At least one side length must be specified in order to completely define a single triangle. These measures create more than one triangle.

Reason:

The x value x = 4 repeats itself. We have the input x = 4 lead to multiple outputs (y = 0 and y = 2) at the same time. This is enough evidence to conclude we do not have a function.

A function is only possible if any given input leads to exactly one output.

If you were to plot these points, then you should note (4,0) and (4,2) fail the vertical line test. To pass the vertical line test, it should be impossible to draw a single vertical line through more than one point.

And, the largest possible number Hannah could be thinking of will be 355.

Rounding numbers refers to changing a number's digits such that it approximates a value. The provided number is more simply represented by this value. For instance, 700,000 rather than 698,869 could be used to express a town's population.

Given that;

Hannah thinks of a whole number.

Rounded to the nearest 10, her number is 350.

And, Rounded to 1 significant figure, her number is 300.

The value of {f(-1)-f(3)}/(-1-3) is 255/16 when f(x) = [tex]4^{x}[/tex].

According to the question,

We have the following information:

f(x) = [tex]4^{x}[/tex]

Now, we will first find the values of f(-1) and f(3) and then we will put these values into the given operation in order to find its value.

f(-1) = [tex]4^{-1}[/tex]

Now, we will inverse this operation to have positive exponents:

f(-1) = 1/4

f(3) = [tex]4^{3}[/tex]

f(3) = 4*4*4

f(3) = 64

Now, we have f(-1)-f(3) in the numerator. So, we will solve this first:

1/4 - 64

(1-256)/4

-255/4

Now, putting all these values in the indicated operation:

(-255/4)/(-1-3)

(-255/4)-4

255/(4*4)

255/16

Hence, the value of {f(-1)-f(3)}/(-1-3) is 255/16 when f(x) = [tex]4^{x}[/tex].

The larger angle in the straight line is 101°.

What is straight line angle?

   A straight angle in mathematics is one with a sine angle of 180 degrees. Due to the fact that it resembles a straight line, it is called straight. Those angles that make a straight line are known as straight angle pairs. Each angle in this pair adds up to 180 degrees, regardless of how many angles make up the pair. A straight angle in geometry is one that is equal to 180 degrees. It looks like a straight line, hence the name "straight angle." It is an angle, then, whose sides are in the same straight line but opposite to the vertex.

We know that , In straight line angle at any point is 180°.

Here,

=> (14x+3)°+(11x+2)°=180°

=>14x+3+11x+2=180

=>25x+5=150

=>25x=180-5=175

=> x = 175/25 = 7.

Then , 14(7)+3=101° and 11(7)+2=79°.

Hence the larger angle is 101°.

The domain of given graph is [-8,8].

The domain of a function is a set of all x values i.e. the numbers for which function is defined. All of a function's x-values, or inputs, make up the domain, and all of a function's y-values, or outputs, make up the range. When viewing a graph, the whole range of numbers from left to right comprise the domain.

The probability of observing an 85°F temperature or higher in Los Angeles during a randomly chosen day in June is 0.266.

We are given information about the temperatures in Los Angeles for the month of June. The average daily high temperature in June in LA is 80°F. The standard deviation in the temperature values is 8°F. The temperatures in June closely followed a normal distribution. We need to find the probability of observing an 85°F temperature or higher in Los Angeles during a randomly chosen day in June. Let the mean, standard deviation, value, z-score, and probability be represented by the variables M, S, X, Z, and P. First of all, we will find the z-score for the given temperature value.

Z = (X - M)/S = (85 - 80)/8 = 5/8 = 0.625

We want to find the probability for Z-values greater than or equal to the calculated z-score. We need to use the z-score table to find the corresponding probability.

Step-by-step explanation:

(a)

substitute x = 5 into f(x) , that is

f(5) = 5² - 10(5) - 17 = 25 - 50 - 17 = 25 - 67 = - - 42

(b)

substitute x = 0 into f(x)

f(0) = 0² - 10(0) - 17 = 0 - 0 - 17 = - 17

By finding all the probabilities we will see that the event that is least likely to occur is the one in option D.

Let's find the probability for each event.

A) The probability is computed as the quotient between the outcomes that meet the conditions for the event and the total number of outcomes.

Here the outcomes are {1, 2, 3, 4, 5, 6, 7, 8}

The outcomes that meet the condition (less than or equal to 6) are:

{1, 2, 3, 4, 5, 6}

So 6 outcomes out of 8 meet the condition, the probability here is:

a = 6/8 = 3/4 = 0.75

B) The probability here is 1, as all the outcomes meet the condition of "landing in some color"

C) If there are 100 tickets in total and you have 29, then the probability of winning is:

b = 29/100 = 0.29

D) There are 10 strawberry chews and 50 cherry chows, so the total number of candy is 50 + 10 = 60, and 10 of these are strawberry chews, then the probability of taking one of these is:

The salary is $55100 when [tex]a_n=55100[/tex].

[tex]55100=41900+1100n\\\\13200=1100n\\\\12=n[/tex]

So, her salary will be $55,100 after 12 years.

The salary is $55100  after 12 years.

An equation is an expression that shows the relationship between two or more numbers and variables.

Given that construction worker's starting salary is $43,000. Each year she receives a $1100 raise.

Therefore, an = 41,900 + 1100n

An explicit formula of the form an = bn + c to model this situation.

When n = 10,

= 41,900 + 1100n

= 41,900 + 1100(10)

= 41,900 + 11000

= 52,900

when an  = 55,100

Then an = 41,900 + 1100n

55,100 = 41,900 + 1100n

1100n = 55,100 - 41,900

1100n = 13200

n = 13200/ 1100

n = 12

So, her salary will be $55,100 after 12 years.
