An elevator went up 15 floors, down 9 floors, up 11 floors, and down 19 floors. Find the net change.
Answer: The net change would be -2.
Step-by-step explanation: The upward change of elevator is represented by positive sign while the downward change represented by negative sign.
Given, First the elevator goes up 15 floors, change = + 15, Then it goes 9 floors down, change = -9, Then it goes 11 floors up,Change = + 11, Finally, it goes 19 floor down, Change = - 19 So, the net change = sum of total changes = 15 - 9 + 11 - 19 = -2

Step-by-step explanation:
A number plus 16 times its reciprocal equals 4. Find all possible values for the number.
All the possible values for the number are [tex]x=2+2i\sqrt{3}[/tex] and [tex]x=2-2i\sqrt{3}[/tex].
Given that, a number plus 16 times its reciprocal equals 4.
The solutions to the quadratic equation are the values of the unknown variable x, which satisfy the equation. These solutions are called roots or zeros of quadratic equations. The roots of any polynomial are the solutions for the given equation.
Let the unknown number be x.
Now, the equation is [tex]x+\frac{16}{x}=4[/tex]
[tex]\frac{x^2+6}{x}=4[/tex]
[tex]x^2+16=4x[/tex]
[tex]x^2-4x+16=0[/tex]
By comparing [tex]x^2-4x+16=0[/tex] with [tex]ax^2+bx+c=0[/tex], we get a=1, b=-4 and c=16.
Substitute these values in quadratic formula [tex]x=\frac{-b\pm\sqrt{b^2-4ac} }{2a}[/tex], we get
[tex]x=\frac{4\pm\sqrt{(-4)^2-4\times1\times16} }{2\times1}[/tex]
[tex]x=\frac{4\pm\sqrt{-48} }{2}[/tex]
[tex]x=\frac{4\pm4i\sqrt{3} }{2}[/tex]
[tex]x=2+2i\sqrt{3}[/tex] and [tex]x=2-2i\sqrt{3}[/tex]
Therefore, all the possible values for the number are [tex]x=2+2i\sqrt{3}[/tex] and [tex]x=2-2i\sqrt{3}[/tex].

The interior angles formed by the sides of a hexagon have measures that sum to 720°.
What is the measure of angle F?
Enter your answer in the box.
m∠F=
°
Answer:
F=140
Step-by-step explanation:
Remember that all angles will be able to add to 720 so you should get something like this:
130+120+110+x-20+x-60+x-40=720
Then solve for x to do this:
130+120+110+x-20+x-60+x-40=720
360-120+3x=720
3x+240=720
3x=480
x=480/3
x=160
With x=160, you can plug in to solve and find that F=140

What is the area of the trapezoid with height 13 units?
Enter your answer in the box.
Answer:
286
Step-by-step explanation:
The equation for Area of Trapezoid is:
[tex]Atrapezoid = \frac{h(b1+b2)}{2}[/tex]
First, replace the variables with their values:
h=13
b1=15
b2=(7+7)+15=29
Now, your equation should look like this:
[tex]Atrapezoid = \frac{13(15+29)}{2}[/tex]
Now, solve:
[tex]15+29=44[/tex]
↓
[tex]\frac{13(44)}{2}[/tex]
↓
[tex]44*13=572[/tex]
↓
[tex]\frac{572}{2}=286[/tex]
The area of the trapezoid is 286.

Triangle VWX has vertices V(0,−3) , W(−4,3) , and X(2,2) .
Write the coordinate notation for a translation of 5 units right and 1 unit up.
Answer:
The answer is below.
Step-by-step explanation:
Hope this helps!
The translation of the triangle is given by V' ( 5 , -2 ) , W' ( 1 , 4 ) , X' ( 7 , 3 )
What is Translation?A translation moves a shape up, down, or from side to side, but it has no effect on its appearance. A transformation is an example of translation. A transformation is a method of changing a shape's size or position. Every point in the shape is translated in the same direction by the same amount.
A translation in the coordinate plane moves every point on a figure a given distance in a given direction. The position of any point (x, y) on the figure changes to (x + a, y + b), where a and b are real numbers.
Given data ,
Let the triangle be represented as VWX
Now , the coordinates of the vertices are
V(0,-3) , W(-4,3) , and X(2,2)
And , the triangle is translated 5 units right and 1 unit up
So , the transformed triangle is given by
V' ( 5 , -2 ) , W' ( 1 , 4 ) , X' ( 7 , 3 )
Hence , the translation rule is ( x + 5 , y + 1 )

What are the measures of ∠CAB and ∠ACB in the figure?
Answer:
See below
Step-by-step explanation:
(7x +3) is the same as angle opposite B
So 7x+3 will equal 103 degrees.
To figure out angle ACB we just take a straight line (180 degrees) and minue 103, which gives us 77 degrees
ACB = 77 degrees
Now we will just isolate x so we can figure out it's value for angle CAB
7x = 103 - 3
7x = 100
x = 100/7
x = roughly 14.3
CAB = 3x - 10 = (14.3 * 3) - 10
= 43 - 10
CAB = 33 degrees
The measure of ∠CAB is 43°.
The measure of ∠ACB is 80°.
What is a triangle?A triangle is a 2-D figure with three sides and three angles.
The sum of the angles is 180 degrees.
We can have an obtuse triangle, an acute triangle, or a right triangle.
We have,
From the figure,
ΔABC
∠A + ∠B + ∠C = 180 ______(A)
And,
∠C = 7x + 3 [ alternate angles ] _____(1)
∠B = 180 - 103 = 77 [ straight angle ] _____(2)
∠A = 3x - 10 _____(3)
Substituting (1), (2), and (3) in (A).
∠A + ∠B + ∠C = 180
7x + 3 + 77 + 3x - 10 = 180
10x + 80 - 10 = 180
10x + 70 = 180
10x = 180 - 70
10x = 110
x = 110/10
x = 11
Now,
∠CAB = 3x + 10
∠ACB = 7x + 3 [ alternate angle with (7x + 3)
Substituting x = 11.
∠CAB = 3 x 11 + 10 = 33 + 10 = 43
∠ACB = 7 x 11 + 3 = 77 + 3 = 80
Thus,
∠CAB = 43
∠ACB = 80

Use the data on the dot plot to answer the question. A dot plot titled How Many Hours did you read last week going from 3 to 6. 3 has 4 dots, 4 has 6 dots, 5 has 3 dots, and 6 has 5 dots. How many people read for more than three hours last week?
14
You need to find all the people who read more than three hours. More than three hours would mean people who read more than 4, 5, or 6 hours. Since the number of people who read 4 hours is 6 dots and 5 hours are 3 dots, we add them together.
6+3
= 9
Since the number of people who read 6 hours is 5, we also add that.
9+5
= 14
Answer:
14
Step-by-step explanation:
More than 3 hours would be 4 hours and 5 hours and 6 hours.
So sum the number of dots above the numbers 4, 5 and 6:
6 + 3 + 5 = 14
