Round 1927.83505155 to the nearest whole number
Answer:
1928
Step-by-step explanation:
1927.83505155 rounded to the nearest whole number is 1928. A whole number is a number with no decimal places, so we'll have to look at the number directly to 7's right (the first decimal) in order to find out whether we'll be rounding up or down. This number is 8, which is closer to 10 than it is to 0, so we'll be rounding up.
1927 + 1 = 1928, and this is our final answer. Hopefully this was helpful! Let me know if you have any further questions on the subject.

What is the sing for pi
Can someone help please
Step-by-step explanation:
2x° + 2x° + 76° = 180° ( being supplementary angle )
4x° = 180° - 76°
4x° = 104°
x = 104/4
x = 26°

So the basic idea of this type of math is if you know how to multiply you are gonna KEEP CHANGE and Flip. Keep the number chand the division sign to a multiplication sign or vise versa the Flip the fraction where the denominator is offically the numerator.
Example 1:
4 divided by 1/2
KEEP CHANGE FLIP
4 x 2/1 =8/1 or 8
See its that simple!
Here is you math
Oh and I did the liberty of Showing you how to do the math problems.

PLEASE HELP For the data set 7, 10, 10, 14, 14 17 the mean is 12. What is the mean absolute deviation
A. The mean absolute deviation is 18
B. The mean absolute deviation is 6
C. The mean absolute deviation is 12
D. The mean absolute deviation is 3
Answer:
D. the absolute deviation is 3
Step-by-step explanation:
Given:
data = [7,10,10,14,14,17]mean = 12MAD:
[tex]\displaystyle \large{\dfrac{1}{n}\sum_{i=1}^{n}|x_i-m| = \dfrac{|x_1-m|+|x_2-m|+|x_3-m|+...+|x_n-m|}{n}}[/tex]
Therefore:
[tex]\displaystyle \large{MAD=\dfrac{|7-12|+|10-12|+|10-12|+|14-12|+|14-12|+|17-12|}{6}}\\\displaystyle \large{MAD=\dfrac{5+2+2+2+2+5}{6}}\\\displaystyle \large{MAD=\dfrac{18}{6}}\\\displaystyle \large{MAD = 3}[/tex]
Therefore, absolute deviation is 3

Which plane is closer to the base of the airport tower? Explain.
Write the distance for each plane to the nearest 10th
Answer:
Plane B is closer.
Step-by-step explanation:
Plane B is closer.
The distance for Plane A is 7.9 km.
The distance for Plane B is 7.4 km.
Step-by-step explanation:
To find the distance to the tower, altitude must be converted to kilometers. Each 1000 ft is 0.3048 km, so the heights of the planes are ...
-- Plane A: (20 thousand ft)*(0.3048 km/thousand ft) = 6.096 km
-- Plane B: (8 thousand ft)*(0.3048 km/thousand ft) = 2.4384 km
The Pythagorean theorem can be used to find the distance from each plane to the tower:
-- distance = √((ground distance)² + (height)²)
-- Plane A distance = √(5² +6.096²) ≈ √62.16 ≈ 7.9 . . . km
-- Plane B distance = √(7² +2.4384²) ≈ √54.95 ≈ 7.4 . . . km
The distance for Plane B is shorter, so Plane B is closer to the tower.

52.5 Yards (yd).
7 + 7 = 14
14 + 14 = 28 ( 10 + 10 + 4 + 4)
14 + 28 = 42 (4 - 2 + 8 = 10 + 20 + 10)
42 + 10.5 = 52.5
⚠⚠ if you need to multiply this by itself (squaring is the proper name) then the answer is 2756.25 Yards.
I am going into the hard math now, Will you please help me understand this problem?
Answer:
17.6
Step-by-step explanation:
I like to approach surface area problems by solving the invdividual 2d shapes on the figure.
First we will solve the triangle(s)
1/2xbh=a
1/2x2=a
1=a
As there is another triangle reflected behind it we so far have 2 units.
Now we solve the 3 rectangles in the figure
3x2.2 = 6.6 (first slanted rectangle)
3x1= 3 (bottom rectangle)
2x3=6 (side rectangle)
Now we add up all our units
2 + 6 + 3 + 6.6
17.6 = SA
Please help needed its due soon

Median is 29.5.
Q1 is 24.
Q3 is 32.
32-24=8
13. Factor the expression completely
5x²-30x+45
Answer:
5(x-3)(x-3)
Step-by-step explanation:
First we can divide everything by 5:
[tex]\frac{5x^{2} -30x+45}{5} = x^{2} -6x+9[/tex]
Now we find 2 numbers that multiply to give +9 and add to give -6:
This would be -3 and -3. Now we substitute these numbers inside of -6 by splitting -6x into -3x and -3x:
[tex]x^{2} -3x-3x+9[/tex]
Now we factor the first 2 terms:
[tex]x(x-3)[/tex]
Now we factor the last 2 terms:
[tex]-3(x-3)[/tex]
Now we only copy one bracket and the things outside the bracket we put them into 1:
(x-3)(x-3)
Now we multiply everything by 5 :
5(x-3)(x-3)
Answer:
5(x-3)( x-3)
Step-by-step explanation:
First we notice that all the factors are divisible by 5 because the ending of the coefficients is 0 or 5
5 (x² -6x+9)
5 ( x -3) ² , because x² -6x+9 = 9x-3)²
5 (x-3)( x-3)
a + 6.6 = 12.6 helpp please !
Answer:
it is 6
Step-by-step explanation:
because if you subtract 12.6 - 6.6 = 6 so 6 + 6.6 is 12.6
Answer:
A = 6
Step-by-step explanation:
To solve the equation A + 6.6 = 12.6, you need to isolate the variable "A," which represents an unknown value.
Subtract 6.6 from both sides of the equation:
=> A + 6.6 - 6.6 = 12.6 - 6.6
Simplifying this equation gives:
=> A = 6
Therefore, the solution to the equation A + 6.6 = 12.6 is A = 6.

What is the y-intercept, axis of symmetry and vertex of the following function.
SHOW WORK!!!!!!!!!!!
[tex]F(x)=-3x^{2} -6x-5[/tex]
I will give brainilst help please
Complete the square:
F(x) = -3x² - 6x - 5
F(x) = -3 (x² + 2x) - 5
F(x) = -3 (x² + 2x + 1 - 1) - 5
F(x) = -3 ((x + 1)² - 1) - 5
F(x) = -3 (x + 1)² + 3 - 5
F(x) = -3 (x + 1)² - 2
The y-intercept has x-coordinate equal to 0, so it corresponds to the value of F(0) :
F(0) = -3 (0 + 1)² - 2 = -3 - 2 = -5
The axis of symmetry is the vertical line running through the vertex of this parabola, so we'll come back to this.
The vertex of the parabola is (-1, -2). This represents the maximum value of F(x), which follows from
(x + 1)² ≥ 0 ⇒ -3 (x + 1)² ≤ 0 ⇒ -3 (x + 1)² - 2 ≤ -2
This is to say, every point on the parabola has a y-coordinate no greater than -2.
As mentioned earlier, the axis of symmetry is the vertical line through the vertex, and its equation is determined by the x-coordinate of the vertex. Hence the AoS is the line x = -1.
Joshua wants to purchase a new cell phone, but he does not have enough money in his bank account to pay for one. Which of these is not an option for Joshua?
Answer:
The answer is the debit card.
Step-by-step explanation:
Because a debit card takes money straight from your bank account and if he doesn't have enough money in his bank account he can't pay for it. Does that make sense?? If not let me know and I will explain it better.
Answer:
Debit card
Step-by-step explanation:
He doesn't even have enough money and debit cards base your spending limit on how much money you have in your account.

The first sequence rule is multiply by 4 starting from 7. The second sequence rule is add 5 starting from 8. What is the first number that appears in both sequences?
Answer: The first number that appears in both sequences is 28.
Step-by-step explanation:
Let's write down numbers from each of the sequences
Sequence 1) We need to start from 7 and multiply 4
7x4=28, 28x4=112
The sequence is 7,28,112...
Sequence 2) We need to start from 8 and add 5
5+8=13, 13+5=18, 18+5=23, 23+5=28
The sequence is 8,13,18,23,28...
They both have 28
28 is the first number that appears in both sequences.
multiply by 4 starting from 7
First sequence: 7 * 4 = 28 *4 = 112 * 4 = 448add 5 starting from 8
Second sequence: 8 + 5 = 13 + 5 = 18 + 5 = 23 + 5 = 28
