A person lost in an office building travels up 3 floors in an
elevator, then down 1 floor, then up 5 more floors, then
down another 4 floors. What number sentence would
represent this situation?

Answer:

y=63, x=20, x=47, b=70, c=89, x=133

Step-by-step explanation:

1) y=63- alternate angles are the same

2) 4x+5x=180

9x=180

x=20

3) x=47

4) b=70- angles on a line equal to 180

c=89- angles in a triangle add up to 180

5) x=133- angles that are alternate are the same

cos 48° = b / √(a²+b²)

tan 48° = a/b

sin 48° = a / √(a²+b²)

Answer:

The quantities x and y are in a proportional relationship.

Answer:

Total rent= $900

Step-by-step explanation:

Giving the following information:

Total monthly budget= $3,000

Percentage of rent in the budget= 30%

To calculate the monetary value paid in rent, we need to use the following formula:

Total rent= percentage of rent paid*total monthly budget

Total rent= 0.3*3,000

Total rent= $900

Answer:

No

Step-by-step explanation:

First subtract 16 from both sides

13 is not a solution to the original inequality.

here's the solution,

rumba got 250 marks !!

Theoretical probability that a roll will not land on a star

From the attachment, we have:

[tex]n = 12[/tex] --- Total space

[tex]Star = 4[/tex]

So, the theoretical probability that a roll will land on a star is:

[tex]P(Star) = \frac{n(Star)}{n}[/tex]

[tex]P(Star) = \frac{4}{12}[/tex]

[tex]P(Star) = \frac{1}{3}[/tex]

Using the complement rule, the probability that it will not land on a star is:

[tex]P(Not\ Star) = 1 - P(Star)[/tex]

[tex]P(Not\ Star) = 1 - \frac{1}{3}[/tex]

Take LCM

[tex]P(Not\ Star) =\frac{3-1}{3}[/tex]

[tex]P(Not\ Star) =\frac{2}{3}[/tex]

Answer:

75 sq units

Step-by-step explanation:

A = lw

l = OP = distance between (9, 6) and (0, -6)

          = [tex]\sqrt{(9 - 0)^{2} + (6 + 6)^{2} }[/tex]

         = [tex]\sqrt{81 + 144)} = \sqrt{225} = 15[/tex]

w = MP =  distance between (-4, -3) and (0, -6)

            = [tex]\sqrt{(-4 - 0)^{2} + (-3 + 6)^{2} }[/tex]

            = [tex]\sqrt{16 + 9} = \sqrt{25} = 5[/tex]

A = 15(5) = 75 sq units

Answer:

Option A

Step-by-step explanation:

Just substitute each value of x in the graph to find the correct function.

When be graph the functions given, we find that option A is correct.

To graph a function, you have to select x-values and plug them into the equation. Once you plug those values into the equation, you will get a y-value. Your x-values and your y-values make up your coordinates for a single point. Keep plugging in x-values to get coordinates to plot more points on the graph, and then you will see your graphed function once the dots are connected.

Using the graph,

For x < = -2, y = 5.

For -2 < x < 1, the function is a polynomial.

We have two options, either [tex]y = x^{2} -5\ or\ y = x^{2} +5[/tex]

The polynomial must have the point (0,-5) on it.

For [tex]y = x^{2} -5[/tex] , when x = 0, y = -5.

Hence, it is the correct option.

For x >= 1,

Using graph, we see that when y = 0, x lies between 3 and 4.

For equation, [tex]y = 2^{(x-2)} - 2\\[/tex], when y = 0, x = 3, so it is not correct.

For equation, [tex]y = 2^{(x-2)} - 3\\[/tex], when y = 0, x = 3.584, hence it is correct.

Answer:

the answer is D

Step-by-step explanation:

The Dot plot for Alia's Sample is plot D.

Based on the values of each point, a dot plot visually groups the number of data points in a data set. Similar to a histogram or probability distribution function, this provides a visual representation of the data distribution.

Tasneem has a sample of 12 bags of candy.

Now, the median for Tasneem sample space is

= (47.1 + 47.2)/ 2

= 47. 15

As, the median mass in A is 47.05, B is 47.1, in C is 47.1 and in D is 47.4.

Also, we know that the median mass for Alia's Sample is greater than Tasneem.

Thus, the correct plot is D.

Answer:

81 m

Step-by-step explanation:

From the question given above, the following data were obtained:

Area (A) = 7371 m²

Length (L) = 91 m

Width (W) =?

Area of a rectangle is given by the following equation:

Area = Length × Width

A = L × W

With the above formula, we can obtain the width of the rectangular field as follow:

Area (A) = 7371 m²

Length (L) = 91 m

Width (W) =?

A = L × W

7371 = 91 × W

Divide both side by 91

W = 7371 / 91

W = 81 m

Thus, width of the rectangular field is 81 m
