Find the missing value to complete the square.
x^2 + 8x + __ = 0
Answers
Answer:
−x^2 − 8x
Step-by-step explanation:
Lets say y is the missing value
Add -x^2 to both sides.
x^2+8x+y+−x^2=0+−x^2
8x+y=−x^2
Add -8x to both sides.
8x + y + −8x = −x^2 + −8x
y = −x^2 − 8x
So the whole equation would be
x^2 + 8x + −x^2 − 8x = 0

If the ratio of the two sides of the triangles are the same then the third sides of the triangle will be parallel. Then the correct figure is D.
What is the triangle?A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.
If the ratio of the two sides of the triangles are the same then the third sides of the triangle will be parallel.
⇒ 5.5/15 = 6.6/18
⇒ 0.366 = 0.366
Then the correct figure is D.

gonzalo nacio el 18 de sptiembre de 1945 si bertha nacio cuatro decadas y un lustro cual es la fecha de nacimiento de bertha
Answers
Answer: Bertha nació el 18 de septiembre de 1990.
Step-by-step explanation:
Gonzalo nació el 18 de septiembre de 1945.
Bertha nació cuatro décadas y un lustro después.
Una década son 10 años
Un lustro son 5 años
Entonces 4 décadas y un lustro son:
4*10 años + 5 años = 45 años
Esto significa que Bertha nació 45 años después que Gonzalo.
Entonces si Gonzalo nació en 1945, Bertha nació en el año:
1945 + 45 = 1990
Bertha nació el 18 de septiembre de 1990.
La fecha de nacimiento de Bertha es el 18 de septiembre de 1990.
How many years does a decade have?A decade is composed of 10 years. So, if there are 'x' decades, then that means there are going to be [tex]10 \times x[/tex] years in it.
For this case, we are given that:
Date of birth of Gonzelo is 18th of Sept. 1945
Bertha born after 4 decades and 5 years of Gonzelo's birth.
4 decades = 4 times 10 = 40 years
Thus, 4 decades + 5 years = 40 + 5 = 45 years.
45 years after 1945 uis 1945 + 45 = 1990
Thus, date of birth of Bertha is 18th Sept. 1990

so ive been noticing a lot of posts on this platform lately that are asking people to do entire essays or worksheets for 10 points? nobody will do that for you, and whenever someone actually does, stop saying 'can you elaborate on that'. it will just fail you later in life when you realize that you cant just keep using others to do ALL of your work.

Answers
Answer:
A.) 555 in.^2
Step-by-step explanation:
When solving these types of things, I usually like to cut it up into smaller, easier to manage shapes.
You can cut that trapezoid into two triangles and one rectangle.Since both triangles are the same size, you don't need to divide the base and height by two, so you'll get the area of both triangles combined (which saves some work). We know the length of the rectangle and bases of the triangle combined is 44 inches, and that the length of just the rectangle is 30 inches, so we can just subtract 30 from 44 and divide it by two for the base of a triangle.44 - 30 = 14
14/2 = 7
Now that we filled in the information not listed, we can finally solve:
The base of one triangle is 7 inches, and the height is 15 inches.
Now, we just multiple and divide it by 2 for one triangle (it would be 52.5 inches).
But, we don't need to divide it by two because both triangles are the same size, so we can just get the sum of the area of both triangles combined by skipping that step (because triangles are half a square and two of those triangles make a full square).
7 x 15 = 105
The area of both triangles combined: 105 in.^2
Next, we need to solve the area of the rectangle. This is easy considering all you have to do is multiply 15 by 30 (length times width).
15 x 30 = 450
The area of the rectangle: 450 in.^2
Now, the final step. Addition. All you need to do is add up all the sums, and you're done.
450 + 105 = 555
The area of entire figure: 555 in.^2
NOTE: the symbol '^' represents exponents, so when you see 555 in.^2, it means inches squared (or to the power of 2)
If 420 = 120%, what would 100% equal?
Answers
Answer:
350
Step-by-step explanation:
Introduction. Percent, p%
'Percent (%)' means 'out of one hundred':
p% = p 'out of one hundred',
p% is read p 'percent',
p% = p/100 = p ÷ 100
120% = 120/100 = 120 ÷ 100 = 1.2
100% = 100/100 = 100 ÷ 100 = 1
Percentage of 120% of what number = 420?
120% × ? = 420
? =
420 ÷ 120% =
420 ÷ (120 ÷ 100) =
(100 × 420) ÷ 120 =
42,000 ÷ 120 =
350
ProofHow do we check the result?If 120% × 350 = 420 =>
Divide 420 by 350...
... And see if we get as a result: 120%
Note:Multiply a number by the fraction 100/100,
... and its value doesn't change.
100/100 = 100 ÷ 100 = 1
n/100 = n%, any number.

The first two shipping companies provided their data from a sample of drivers in a table.
Company C showed its data in a dot plot.

3. Which company had the greatest mean number of deliveries?
Write your answer in the space below.
4. Compare the means for companies A and B. By how many times the MAD do their means differ? Show your work.
Write your answer in the space below.
Answers
Answer:
Step-by-step explanation:
1. the company C used 10 drivers
2. 6 + 7 + 8 + 9 + 10 + 10 + 10 + 12 + 14 + 14 = 100/10. The Mean = 10
(6- 10) + (7- 10) + (8- 10) + (9- 10) + (10- 10) + (10- 10) + (10- 10) + (12- 10) + (14- 10)
4 + 3 + 2 + 1 + 0 + 0 + 0 + 2 + 4 = 16/10 = 1 6/10
3. The groups that had the most deliveries where group A and B
4. So if there are 6 deliveries of group A and 14 deliveries from group B i think the MAD would be 4
By reading the dot plot,
Number of drivers used by company C in its sample = 10
Mean absolute deviation for company C's data = 2
Company B has the greatest mean number of deliveries.
The mean deliveries of company B is 4 times MAD of company A.
What is dot plot?Dot plot is a simple form of data visualization that consists of data points plotted as dots on a graph with an x- and y-axis.
Number of units used in the sample of a dot plot can be calculated by simple counting.
What is mean absolute deviation?The mean absolute deviation (MAD) is the mean distance between each data value and the mean of the data set.
We are given the sum of each point from the mean. It is 20. Mean absolute deviation can be calculated by dividing this sum by number of observations.
Mean absolute deviation of company C = 20/10 = 2.
Mean A = 6
Mean B = 14
Mean B - Mean A = 8 = 4 * 2 = 4 times MAD (since MAD =2 for both companies).
