Answer:
A:-3<x<13
B:-3=<x=<13
C:-3=<x<13
D:-3<x=<13
Step-by-step explanation:
Ok, first lets do A
-3 and -13 and the endpoints and the dots are hollow so its not including
therefore the answer is -3<x<13
next, B
same endpoint this time but both dots are filled in so they are included
therefore: -3=<x=<13
(I'm typing on a keyboard!!! i can't do the fancy symbols lol)
C
same endpoints again but -3 is black and 13 is not
so: -3=<x<13
D
I think you have got the hang of it now probaly
-3 is not filled and 13 is
answer is -3<x=<13
Hope this helps :)
Translate the name into a decimal number.
negative fifty-five and five ten–thousandths
Answer:
-55 5/10000
Step-by-step explanation:
We can break each word down. Negative would be the negative sign (-), fifty-five would be 55, and five ten-thousandths would be 5/10000. If we put them together, we would get -55 5/10000, which is the answer.
The first term of an arithmetic sequence is 3. The common difference of the sequence is 1.5 tune the first term. Write the next five terms in the sequence:
Answer:
3, 7.5, 12, 16.5
Step-by-step explanation:
Tn = a + (n-1)d
a = 3 and d = 1.5×3 = 4.5
T2 = a + d = 3 + 4.5 = 7.5
T3 = a + 2d = 3 + 2(4.5) = 12
T4 = a + 3d = 3 + 3(4.5) = 16.5
Hope its correct and have a great day :)
what is 2 X (6+ 2 + 8) -4
Answer:
The correct answer is 32x - 4

Factorize the following:

Answer:
(7x+5)(7x-5)
Step-by-step explanation:
We can use the difference of squares equation which states that when a number is multiplied like: (ax+b)(ax-b) then it equals (ax-b). In this equation, since there is no "b" in the typical ax^2+bx+c, we can recognize that the answer is not a square, but a difference of squares.

Explain what each of the numbers-20, -40, and -60 tells you about
hike 5. What does it mean for the numbers to be negative in this
situation?
Answer:
Hike 1 : 768, -96, 672
Hike 2: -62, 82, 20
Hike 3: 62, -100, -38
Hike 4: 354, -225, 129
Hike 5: -20, -40, -60
The -20 is at what surface level Lin began Hike 5 at. From there, they continued to go in this situation lower by - 40, and arrive at the surface region of -60.
Negative numbers in the present circumstance mean under 0. (Underneath surface region)

The surface area of the square pyramid is, A. 80 in².
What is a pyramid?A three-dimensional figure is a pyramid. Its base is a flat polygon. The remaining faces are all triangles and are referred to as lateral faces.
The number of sides on its base is equal to the number of lateral faces. The line segments that two faces intersect to form its edges. The intersection of three or more edges forms a vertex.
The given figure is a pyramid having a square base.
The pyramid also has four triangular faces, each having a base of 5 in and a height of 8 in.
Therefore, the surface area of the pyramid is,
= 4[(1/2)×5×8] square inches.
= 80 in².

You see a hiker sitting on a bench taking a water break at the top of a hill at a 40° angle of elevation. Your eye level is 5 feet off the ground and you are standing 100 feet from the base of the hillAt what altitude is the hiker sitting on the bench?
Answer:
89
Step-by-step explanation:
Draw a right triangle, put the angle of elevation as 40 degrees and the feet for the base of your triangle (standing 100 feet from the base of the hill) as 100ft. According to SOH CAH TOA, we will be using tan, where you will get:
tan(40)=x/100
x=100tan(40)=83.9
Add 5 feet, which was your eyes off the ground, and it will be 83.9+5=89
Final Answer: 89
The altitude of the hiker sitting on the bench of the hill is 89 feet.
What is trigonometry?Trigonometry is mainly concerned with specific functions of angles and their application to calculations. Trigonometry deals with the study of the relationship between the sides of a triangle (right-angled triangle) and its angles.
For the given situation,
The angle of elevation = 40°
Distance from base of the hill = 100 feet
Distance from the ground to the eye level = 5 feet
The diagram below shows the right angled triangle.
Let the altitude from the eye sight to the bench be x.
Total altitude = x + 5
The altitude of the hiker can be found by using trigonometric ratio,
[tex]tan\theta= \frac{opposite}{adjacent}[/tex]
⇒ [tex]tan 40=\frac{x}{100}[/tex]
⇒ [tex]0.8390=\frac{x}{100}[/tex]
⇒ [tex]x=83.90[/tex]
Total height = [tex]x+5[/tex]
⇒ [tex]83.90+5[/tex]
⇒ [tex]88.90[/tex] ≈ [tex]89[/tex]
Hence we can conclude that the altitude of the hiker sitting on the bench of the hill is 89 feet.

Jamal's inequality is correct
Step-by-step explanation:
Given
[tex]Sets:\{0,1,3,4,6,12\}[/tex]
Gary: [tex]6>0.5t[/tex]
Nancy: [tex]30 -t \le 18[/tex]
Jamal: [tex]12 \le t+12[/tex]
Required
Which of the inequalities is/are true
Gary: [tex]6>0.5t[/tex]
[tex]6>0.5t[/tex]
Divide both sides by 0.5
[tex]\frac{6}{0.5} > \frac{0.5t}{0.5}[/tex]
[tex]12 > t[/tex]
Rewrite as:
[tex]t < 12[/tex]
Gary's inequality is false because: [tex]12 = 12[/tex]
Nancy: [tex]30 -t \le 18[/tex]
[tex]30 -t \le 18[/tex]

Divide both sides by -1

Answer:
1) -3/2
Step-by-step explanation:
The common ratio is the amount you multiply by to get to the next number in the sequence. To calculate this you will need to divide the term by its preceding term.
For example (3/4) / (-1/2)
When dividing by fractions you should apply KCF (Keep Change Flip), so you will end up with (3/4) x (-2/1) = -3/2
Check this by doing the next term (-9/8) / (3/4)
When dividing by fractions you should apply KCF (Keep Change Flip), so you will end up with (-9/8) x (4/3) = -3/2

An incomplete sentence is given. “The value of 2 x 1014 is times the value of 4 x 106" What number correctly completes the sentence?
Answer:
0.00000002
Step-by-step explanation:
Let the unknown number be x.
Translating the word problem into an algebraic expression, we have;
2 * 10¹⁴ * x = 4 * 10⁶
To find the value of x;
x = 4 * 10⁶/2 * 10¹⁴
x = 2 * 10^{-8}
Therefore, the value of 2 x 10¹⁴ is 0.00000002 times the value of 4 x 10⁶

325m = c
Step-by-step explanation:
Each meeting room has 325 chairs.
Since we don't know how many meeting rooms there are, the number is replaced with the variable, m.
An equation is a problem with an equals sign so you need to put what it would equal.
Since you don't know how many meeting rooms there are you use the variable, c which represents the total number of chairs.
