If the estimated length of all four trails is 12 miles the possible length for trail D will be 3.4 miles.

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.

Terms are similar, and we can perform arithmetic operations on them like addition and subtraction.

It is obtained from the table that the length of trails A, B, and  C will be 2.6, 1.8, and 4.2 miles.

It is given that the estimated length of all four trails is 12 miles the length of Trail D is obtained by adding all the given lengths of the trails and subtracting it from the total length.

= 2.6 + 1.8, + 4.2 miles.

= 8.6 miles

The length of trail D is,

= 12 miles - 8.6 miles

= 3.4 miles.

Thus, if the estimated length of all four trails is 12 miles the possible length for trail D will be 3.4 miles.

Step-by-step explanation:

Hello!

It said that 7 cameras cost $308, right?

If each camera costs the same, it means that 7 cameras with the same value equal $308.
If we use this in an equation, and if x is a variable we want to solve, it would be:

7x = 308.

If 7x = 308, it would be

308/7 =

44.

So, $44 is the answer.

Answer:

y=10x+125

Step-by-step explanation:

rise over run, so y goes up by 10 each time and x goes up by one each time so that's your X, your b is where it starts at zero so if you did -1 for x you get zero but you have to do that with the y also so 135-10=125, 125 is where your y starts and that's your b

The expression equivalent to\((1/\sqrt y)^(^-^1^/^5^) is y^(^1^/^5^)/ \sqrt y\).

To simplify the expression (1/√y)^(-1/5), we can use the rule for negative exponents, which states that a negative exponent is equivalent to a positive exponent when the base is moved to the opposite side of the fraction.

First, we can simplify (1/√y) by rationalizing the denominator as follows:

1/√y = 1/√y * √y/√y = √y/√(y^2) = √y/y

Therefore, (1/√y)^(-1/5) can be written as:

\([(\sqrt y/y)^(^-^1^)]^(^1^/^5^)\)

Next, we can use the rule for raising a power to another power, which is to multiply the exponents:

\([(\sqrt y/y)^(^-^1^)]^(^1^/^5^) = (\sqrt y/y)^(^-^1^/^5^)\)

Finally, we can use the negative exponent rule again to rewrite (√y/y)^(-1/5) as:

\((y/√y)^(1/5)\) = \((1/\sqrt y)^(^-^1^/^5^) is y^(^1^/^5^)/ \sqrt y\)

(A)  the annual rate of change between 1992 and 2006 was 0.0804

(B) r = 0.0804 * 100% = 8.04%

(C) value in 2009 = $11,650

What is the rate of change?

The rate of change is a mathematical concept that measures how much one quantity changes with respect to a change in another quantity. It is the ratio of the change in the output value of a function to the change in the input value of the function. It describes how fast or slow a variable is changing over time or distance.

A) The initial value is $44,000 and the final value is $15,000. The time elapsed is 2006 - 1992 = 14 years.

Using the formula for an annual rate of change (r):

final value = initial value * \((1 - r)^t\)

where t is the number of years and r is the annual rate of change expressed as a decimal.

Substituting the given values, we get:

$15,000 = $44,000 * (1 - r)¹⁴

Solving for r, we get:

r = 0.0804

So, the annual rate of change between 1992 and 2006 was 0.0804 or approximately 0.0804.

B) To express the rate of change in percentage form, we need to multiply by 100 and add a percent sign:

r = 0.0804 * 100% = 8.04%

C) Assuming the car value continues to drop by the same percentage, we can use the same formula as before to find the value in the year 2009. The time elapsed from 2006 to 2009 is 3 years.

Substituting the known values, we get:

value in 2009 = $15,000 * (1 - 0.0804)³

value in 2009 = $11,628.40

Rounding to the nearest $50, we get:

value in 2009 = $11,650

Hence, (A)  the annual rate of change between 1992 and 2006 was 0.0804

(B) r = 0.0804 * 100% = 8.04%

(C) value in 2009 = $11,650

Comparing the median of each box-and-whisker plot, the type of transportation that is LEAST likely to take more than 30 minutes is: d. train.

How to Interpret a Box-and-whisker Plot?

In order to determine the transportation that is LEAST likely to take more than 30 minutes, we have to compare the median of each data set represented on the box-and-whisker plot for each transportation.

The box-and-whisker plot that has the lowest median would definitely represent the the transportation that is LEAST likely to take more than 30 minutes, since median represents the typical minutes or center of the data.

Therefore, from the box-and-whisker plots given, the one for train has the lowest median. Therefore train would LEAST likely take more than 30 minutes.

Step-by-step explanation:

Answer:

Area of the shaded region = 87.5 cm²

Step-by-step explanation:

Area of the shaded region = Area of the sector - Area of the triangle

Area of the sector = \(\frac{\theta}{360}\times (2\pi r)\)

Here, θ = Central angle subtended by the arc

r = radius of the circle

Area of the given sector = \(\frac{120}{360}\times (\pi r^{2})\)

                                         = 48π

                                         = 150.796 cm²

From ΔABC,

Central angle BAC = 120°

Since, AD is an angle bisector of ∠BAC,

m∠BAD = m∠CAD = 60°

∠ADC = 90° [By theorem, line from the center to any chord is a perpendicular bisector of the chord in a circle)

Now,  cos(60) = \(\frac{AD}{AC}\)

\(\frac{1}{2}=\frac{AD}{12}\)

AD = 6

Similarly, sin(60) = \(\frac{DC}{AC}\)

\(\frac{\sqrt{3} }{2}=\frac{DC}{12}\)

DC = \(6\sqrt{3}\)

Since, BC = 2(DC) = \(12\sqrt{3}\)

Area of ΔABC = \(\frac{1}{2}(\text{Height})(\text{Base})\)

                        = \(\frac{1}{2}(AD)(BC)\)

                        = \(\frac{1}{2}(6)(12\sqrt{3})\)

                        = \(36\sqrt{3}\) cm²

                        = 62.35 cm²

Now area of the shaded region = (150.796 - 62.35)

                                                     = 87.456

                                                     ≈ 87.5 cm²

Step-by-step explanation:

We substitute -1+1/6y for x in the second equation (bottom equation) in order to solve the system by the substitution method.

The given system of equations are 2x-1/3y = -2...(1)

3x+y=1...(2)

We solve this system of equations by using substitution method.

Let us solve for x in equation to substitute it in equation (2).

2x=-2+1/3y

Divide both sides of equation by 2.

x=-1+1/6y

Now plug in the value of x in equation 2.

Hence, we substitute -1+1/6y for x in the second equation (bottom equation) in order to solve the system by the substitution method.
