The builder of a parking garage wants to build a ramp at an angle of 16 degrees covers a horizontal span of 55 feet. How long will the actual ramp be? Round yoursolution to four decimal places.

Answers

Answer 1

Let's draw the ramp to better understand the problem:

For us to be able to determine how long the ramp will be, we will be using the Cosine Function.

We get,

[tex]\text{ Cosine }\Theta\text{ = }\frac{\text{ b}}{\text{c}}[/tex][tex]Cosine(16^{\circ})\text{ = }\frac{55}{x}[/tex][tex]x\text{ = }\frac{55}{Cosine(16^{\circ})\text{ }}[/tex][tex]\text{ x = }\frac{55}{0.9612616959}[/tex][tex]x=57.216468974668940618504468175387[/tex][tex]\text{ x }\approx\text{ 57.2165 feet}[/tex]

Therefore, the answer is 57.2165 feet.

how do you do order of operations with negitive signs

Answers

Let's use some examples where we have order of operations and also there are negative numbers and signs involved:

Let's evaluate the following:

(-4) x 5 + (-6)

So order of operations tells us to first take care of the multiplications and after that, deal with the additions or subtractions.

So the multiplication goes first here:

(-4) times 5 = - 20

Recall that a positive number times a negative number gives alwasy a negative number. So negative times positive gives the negative sign to the multiplication, and then, once the sign is taken care of, you multiply the numbers (4 x 5 = 20)

Next, we do the indicated addition

-20 + (-6) = -20 - 6 = -26

weher again we use the property that the + times the - inside the parenthesis gives a minus. ad we finalize by doing -20 - 6 = -26 (combining of two negative numbers).

Another example:

(8 + (-5)) x (-8)

So we first work on solving what is inside the first parenthesis :

8 + (-5) this is 8 - 5 (as we did before, the plus outside the parenthesis where -5 is, results in a minus sign as it multiplies the "-" that is shown ahead of 5.

So, inside this parenthesis we get: 8 - 5 = 3

Now we are left to multiply 3 times (-8)

This is a product of a positive number (3) times a negative number (-8). Again, do the rule for product of the signs (positive times negative equals negative) , ad then the product of the numbers: 3 x 8 = 24

so the answer is - 24

Another example:

(-9) x ((-10)+ 10)

We need to start by solving the operation indicated inside the parenthesis:

(-10) + 10 This is the same as: - 10 + 10 = 0

Now, whenwe use this result in the full expression, we get:

(-9) x 0 = 0 SInce any number multiplied times zero is zero.

Polygon BCDE ≅ polygon RSTU. Find the value of X and the value of Y

Answers

By comparing both polygons, we can tell that they are not the same polygon, since one of the sides has length 11 in one trapezoid and 12 in the other. So, this polygons are similar. We notice that the variables X and Y are part of the angles. In polygons that are similar, the measure of the homologous angles are equal. By homologous we mean angles that are located at the same place in both figures. To determine the homologous angles, we should have both figures drawn in the same orientation. To do so, we will flip the trapezoid on the left, so its orientation matches the one fromt the right. I picture of this flipping would be

From this picture, by comparing it to the other polygon, we determine that the angle EDC is homologous to the angle UTS. So, their measure should be the same. So, we get the following equation

[tex]2y\text{ - 37 = }y+2[/tex]

By adding 37 on both sides and subtracting y on both sides, we get

[tex]2y\text{-y = +2 +37 = 39}[/tex]

This implies that y = 39°.

By doing the same procedure, we find that the angles URS and CBE are homologous. So their measures are equal and we get the equation

[tex]51\text{ = }2x+13[/tex]

Then, by subtracting 13 on both sides

[tex]2x\text{ = 51-13 = 38}[/tex]

If we divide both sides by 2 we get

[tex]x=\frac{38}{2}=19[/tex]

So x = 19°.

If OA-OB-OC and if AOB = 9x + 20, BOC = 7x - 6 and AOC = 142 find BOC

Answers

The angle BOC has a measure of 50 degrees

How to evaluate the measure of the angle?

From the question, the given parameters about the angles are:

OA-OB-OCAOB = 9x + 20BOC = 7x - 6AOC = 142

The above parameters implies that

AOC = AOB + BOC

Next, we substitute the angle measurements in the above equation

So, we have

142 = 9x + 20 + 7x - 6

Evaluate the like terms

So, we have the following equation

142 = 16x + 14

Evaluate the like terms again

So, we have the following equation

16x = 128

Divide both sides by 16

x = 8

Substitute x = 8 in BOC = 7x - 6

BOC = 7 x 8 - 6

Evaluate

BOC = 50

Hence, the measure of the angle is 50 degrees

The values of the random variable X are given and the corresponding probabilities are to be found.

The probability distribution is binomial.

That is, P(X = x) = ⁿCₓ pˣ (1-p)ⁿ⁻ˣ, where p is the probability of success of X in n trials.

So here values of x are given.

From the table, it is clear that p = 0.7

Answers

The equation which is helpful to determine x, the cost of the labor per hour is 4.25x + 54 = 585.25.

How to form an equation?

Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.

Given that,

x is the labor cost per hour.

The technician worked on the computer for 4.25 hours.

Total labor cost = 4.25x

The total parts cost = $54

The total charged cost = total parts cost + total labor cost

585.25 = 54 + 4.25x

4.25x + 54 = 585.25

Hence "The equation which is helpful to determine x, the cost of the labor per hour is 4.25x + 54 = 585.25".

Answers

One observation (210) given a test at the end of the movie to measure their recall is an outlier because it is above the fence above, as can be seen.

Data should first be arranged as follows in ascending order:

10, 22, 26, 27, 28, 31, 35, 40, 49, 57, 58, 61, 61, 62, 86, 86, 87, 88, 92, 97, 101, 210

There are n = 22 observations. Here n is even. Hence median is the mean of the middle two observations.

Median = (11 + 12) th observation /2 = (58 + 61)/2 = 59.5

We now divide the ordered data equally into two halves. Therefore, there are 11 observations in the lower section and 11 observations in the upper part.

The first quartile now corresponds to the median of the lower half.

Q1 = [(11 + 1)/2] the observation = 6th observation = 31

The third quartile represents the upper half part's median.

Q3 = [(11 + 1)/2] the observation = 6th observation = 87

IQR = Q3 - Q1 = 87 - 31 = 56

Lower fence = Q1 - 1.5 × IQR = 31 - 1.5 × 56 = -53

Upper fence = Q3 + 1.5 × IQR = 87 + 1.5 × 56 = 171

One observation (210) is an outlier since it is above the upper fence, as can be seen.

In order to determine the weighs of the boxes, name x as the larger box and y as the smaller one.

Then, based on the given situation, you can write the following equations:

3x + 2y = 86

8x + 4y = 209

Solve the previous system of equations as follow:

Multiply the first equation by -2 and add the result to the second equation:

(3x + 2y = 86)(-2)

-6x - 4y = -172

8x + 4y = 209

-6x - 4y = -172

2x = 37

Solve the previous equation for x by dividing by 2 both sides:

x = 37/2

x = 18.5

Next, replace the previous value of x into any of the equations of the system, for instance, into the first equation, and solve for y:

3x + 2y = 86

3(18.5) + 2y = 86

55.5 + 2y = 86

2y = 86 - 55.5

2y = 30.5

y = 30.5/2

y = 15.25

Hence, the weighs of the boxes are:

larger box = 18.5 kg

smaller box = 15.25 kg

Answers

The co ordinates of the point B is (12, 12)

Given,

The co ordinates:

Point C = (6, 9)

Point A = (4, 8)

Point B = (x, y)

AC : CB(m : n) = 1 : 3

We have to find the co ordinates of point B.

Lets use the formula to find the coordinates of point C.

C = 1 / (m + n) × (mx₂ + nx₁, my₂ + ny₁)

Where,

C = (6, 9)

m = 1

n = 3

x₁ = 4

x₂ = x

y₁ = 8

y₂ = y

So,

(6, 9) = 1 / (1 + 3) × ((1 × x) + (3 × 4), (1 × y) + (3 × 8))

(6, 9) = 1/4 × (x + 12, y + 24)

(6 × 4, 9 × 4) = (x + 12, y + 24)

(24, 36) = (x + 12, y + 24)

Lets evaluate:

x + 12 = 24 and y + 24 = 36

Solve for x,

x + 12 = 24

Add -12 to both sides

x + 12 - 12 = 24 - 12

We get,

x = 12

Now solve for y,

y + 24 = 36

Add -24 to both sides

y + 24 - 24 = 36 - 24

We get,

y = 12
