Based on the dimensions of the parking area, we know that the cost of resurfacing will be $3,135.

First find the area of the parking area:

Area of trapezoid = (Base ₁ + Base₂) / 2 x Height

= (90 + 100) / 2 x 30

= 2,850 feet²

The cost of resurfacing is:

= Area x cost per square foot

= 2,850 x 1.10

= $3,135

It will cost $3,135 to resurface the place.

The distance the ladder goes up the wall is approximately 12.14 meters.

Trigonometry is a branch of mathematics concerned with relationships between angles and ratios of lengths.

We can use trigonometry to solve this problem.

Let's call the distance the ladder goes up the wall "d". We can use the angle the ladder makes with the horizontal to find the length of the ladder that is leaning against the wall.

We know that the ladder is 15.5 m long, so we can use the sine function to find the length of the ladder that is leaning against the wall:

sin(53° 25') = d/15.5

We can solve for "d" by multiplying both sides by 15.5:

d = 15.5 * sin(53° 25')

Using a calculator, we get:

d ≈ 12.14 m

Therefore, the distance the ladder goes up the wall is approximately 12.14 meters.

2. Add the sales tax amount back to the price.

14 + 1.12 = $15.12

When x is equal to 1, the Function f(x) = -4x - 5 yields a value of -9.

The find ƒ(1) for the function f(x) = -4x - 5, we need to substitute x = 1 into the function and evaluate the expression.

Replacing x with 1, we have:

ƒ(1) = -4(1) - 5

Simplifying further:

ƒ(1) = -4 - 5

ƒ(1) = -9

Therefore, when x is equal to 1, the value of the function f(x) = -4x - 5 is ƒ(1) = -9.

Let's break down the steps taken to arrive at the solution:

1. Start with the function f(x) = -4x - 5.

2. Replace x with 1 in the function.

3. Evaluate the expression by performing the necessary operations.

4. Simplify the expression to obtain the final result.

In this case, substituting x = 1 into the function f(x) = -4x - 5 gives us ƒ(1) = -9 as the output.

It is essential to note that the notation ƒ(1) represents the value of the function ƒ(x) when x is equal to 1. It signifies evaluating the function at a specific input value, which, in this case, is 1.

Thus, when x is equal to 1, the function f(x) = -4x - 5 yields a value of -9.

Answer:

there is only one solution, the answer is (A) one solution -0.6,-1.6.

Step-by-step explanation:

To find out how many solutions the system has, we can solve it using either substitution or elimination method. Let's use the elimination method here:

Y = (2/3)x + 2 --- equation 1

6x - 4y = -10 --- equation 2

To eliminate y, let's multiply equation 1 by 4:

4y = 8/3x + 8

Now, we can substitute this expression for 4y into equation 2 and simplify:

6x - (8/3x + 8) = -10

Multiplying both sides by 3 to get rid of the fraction:

18x - 8x - 24 = -30

Simplifying further:

10x = -6

x = -0.6

Now we can substitute x = -0.6 into either equation 1 or equation 2 to find y:

Using equation 1:

y = (2/3)(-0.6) + 2 = 1.6

Therefore, the solution to the system is (-0.6, 1.6).

Since there is only one solution, the answer is (A) one solution -0.6,-1.6.

Step-by-step explanation:

No. Using multiplication and division, you and your partner will not each get the same number of flips because one can flip 23 times, while the other does it 22 times.

The basic mathematical operations include addition, subtraction, multiplication, and division.

These mathematical operations are performed on numbers, variables, equations, and functions to determine numerical results.

In this situation, we first multiply to get the total number of times the 3 bottles can be flipped.

This total is divided by 2 to see if there will not be a remainder.  The result of the division operation is an odd value.

The number of bottles for flipping = 3

The number of times to flip each bottle = 15 times

The total number of times to flip the 3 bottles = 45 times 93 x 15)

The number of those conducting the bottle flipping experiment = 2

The number of times each partner can flip the bottles evenly = 22.5 times (45/2)

Each partner cannot flip the same number of times based on the mathematical operations because 45 is not an even number.

Answer:

\((a)\ L = 18.84\) --- arc length

\((b)\ A = 113.04\) --- sector area

Step-by-step explanation:

Given

\(r = 12\)

\(\theta = 90\)

Solving (a): The arc length

This is calculated using:

\(L = \frac{\theta}{360} * 2\pi r\)

So, we have:

\(L = \frac{90}{360} * 2* 3.14 * 12\)

\(L = 0.25* 2* 3.14 * 12\)

\(L = 18.84\)

Solving (b): The sector area

This is calculated using:

\(A = \frac{\theta}{360} * \pi r^2\)

So, we have:

\(A = \frac{90}{360} * 3.14 * 12^2\)

\(A = 0.25 * 3.14 * 12^2\)

\(A = 113.04\)

the surface area of the cylinder is approximately 471 dm².

Now, For the surface area of the cylinder, we need to find the lateral area  and the area of the two circular bases.

Since, The formula for the lateral area of a cylinder is

L = 2πrh,

where r is the radius of the cylinder and h is the height.

In this case, the diameter is 10 dm,

So the radius is 5 dm.

And the height is also 10 dm.

Therefore, the lateral area is:

L = 2πrh

L = 2π(5 dm)(10 dm)

L = 100π dm²

The formula for the area of a circle is

A = πr²,

where r is the radius.

In this case, the radius is 5 dm,

So the area of each base is:

A = πr²

A = π(5 dm)²

A = 25π dm²

To find the total surface area, we add the lateral area and the area of the two bases:

SA = 2(Area of Base) + Lateral Area

SA = 2(25π dm²) + 100π dm²

SA = 50π dm² + 100π dm²

SA = 150π dm²

Substitute pi as 3.14, we can calculate:

SA ≈ 150(3.14) dm²

SA ≈ 471 dm²

Therefore, the surface area of the cylinder is approximately 471 dm².

Answer:

\(\approx 13^\circ\)

Step-by-step explanation:

Given two lines with the equations:

\(9x - y = 4\\ 8x + y = 6\)

First of all, let us learn the formula for finding the angle between the two lines with given equations:

\(tan\theta = \dfrac{m_1-m_2}{1+m_1m_2}\)

\(m_1, m_2\) are the slopes of the two lines respectively.

Let us convert the given equation to point intercept form.

Point intercept form of a line is given as:

\(y = mx+c\)

\(y = 9x-4\\y =-8x+6\)

Comparing with slope intercept form, we get:

\(m_1 = 9\\m_2 = -8\)

Using the above formula:

\(tan\theta =\dfrac{9 -(-8)}{1+9(-8)}\\\Rightarrow tan\theta = -\dfrac{17}{71}\\\Rightarrow \theta = -13.46^\circ\\\)

Therefore, the acute angle between the two lines is \(\approx 13^\circ\)

The acute angles between the equations is 13.46 degree.

To find the acute angles between the two equation, let's write out the individual slope of each equation.

Given Data

The given equations can be rearranged into equation of line.

\(9x-y=4\\ y=9x-4\\ slope=m_1=9\)

The second equation can also be rearranged as and solving for the slope

\(8x+y=6\\ y=6-8x\\ y=-8x+6\\ slope = m_2 = -8\)

Since we have the slopes of the two equation, we can now find the acute angle between them.

θ = \(tan^-^1[\frac{m_1-m_2}{1+m_1m_2}]\\ \)

substituting the values and solving for the angle

\(x = tan^-^1[\frac{9-(-8)}{1+(9*-8)}]\\ x = tan^-^1[17/-71]\\ x=-13.46 = 13.46^0\)

The acute angle between the equations is 13.46 degree

Step-by-step explanation:

250% = 250/100 = 2.5

The plant grew 2.5 times its height in 5 weeks.

Be careful with the way you interpret "The plant grew by 250% of its height after 5 weeks." It means that in 5 weeks, the plant grew an amount equal to 2.5 times the original length of the plant. It does not mean that the total height at the end of 5 weeks was 2.5 times the original height.

growth is 5 weeks: 250% of 3 inches = 2.5 × 3 inches = 7.5 inches

height after 5 weeks: 3 inches + 7.5 inches = 10.5 inches
