Greatest to least 9,354 , 9,012 , 9,1 , 9,157
Answer:
9,354,9,157,9,012,9,1
Step-by-step explanation:
First I do thousands place so 3 numbers have 9 for thousands place.
Numbers are
9,354
9,157
9,012
it cant be 9,012 because this number don't have a hundreds place.
But in hundred place 9,354 would be better than 9,157 because 9,354 had 300 while 9,157 only has 100.
So greatest=9,354
Second greatest=9,157
And last 9,000 number third greatest=9,012.
Our last numbers don't have hundreds or thousands,they have ones but 9 is greater than 1 because...
Say you had 9 pizzas and your friend had 1 you would have more or a greater amount so.
Least=1
and second least=9
Meaning order=
9,356=greatest
9,157
9,012
9
1=least

solve for x using the Pythagorean Theorem.
Spontaneous generation is the idea that life can emerge from nonliving matter. Spontaneous
many in the scientific community up until the mid-nineteenth century. A series of simple experiments tested the validity of
this idea. Evidence used to
support spontaneous generation was the observation that foods over time became covered in maggots or fungal and
bacterial growth, implying that these just appeared." The inference behind spontaneous generation is that there is no
"parent" organism
In 1668, Francesco Redi proposed a different hypothesis to explain the specific example of maggots that appeared on spoiled
food. Explain how Redi disproved the idea of spontaneous generation and helped contribute to the idea that cells come from pre-
existing cells.
A)
B)
Redi reasoned that maggots appeared after meat spoiled, breaking down
the rotten meat
Redi reasoned that flies laid eggs on meat, so meat kept away from adult
flies would remain free of maggots
Redi reasoned that meat had to be exposed to air for maggots to appear.
Meat not exposed to air would remain free from maggots.
Redi reasoned that maggots emerged from condensation. As long as the
meat was kept from water sources, there would be no maggots.
09
D)
Answer:
Celss do come from pre existing cell.
Redi reasoned that flies laid eggs on meat, so meat kept away from adult
flies would remain free of maggots it is the example .
What contribution did Francesco Redi make to cell theory?Redi went on to show that while live maggots or flies will reproduce when placed on decomposing flesh in a sealed jar, dead ones would not. This ruled out the existence of any necessary component in extinct organisms as well as the requirement of fresh air for the creation of life.
In a well controlled experiment, Francesco Redi demonstrated how living things are descended from other living things. The third tenet of the cell theory—that cells originate from other living cells—was developed as a result of this research and that of succeeding researchers.
The prehistoric beliefs were put to the test. Francesco Redi disputed the notion that maggots appeared out of thin air from rotting meat in 1668.

Question 2: Look at the students work and solution to the problem. Identify the error that is made and describe it. Solve the problem correctly. Incorrect work/solution Simplify the expression: 7k + 14 - 9k - 10 = 16k + 4 Identify and Explain the error
Answer:
-2k + 4
Step-by-step explanation:
Given:
Incorrect work / solution
7k + 14 - 9k - 10 = 16k + 4
Error is the simplification of the like terms, that is, 7k - 9k
Correct work / solution
7k + 14 - 9k - 10
Collect like terms
= 7k - 9k + 14 - 10
= -2k + 4
The error made was adding 7k and 9k together, instead of subtracting 9k from 7k which gives -2k as answer

Pls hurry, I need help! Solve the following question by factoring:
Answer:
[tex]\huge\boxed{\bf\:x = -\frac{4}{3}}[/tex]
Step-by-step explanation:
[tex]9x ^ { 2 } +24x+20=4[/tex]
Bring 4 to the left hand side of the equation .
[tex]9x^{2}+24x+20-4=0[/tex]
Subtract 4 from 20.
[tex]9x^{2}+24x+16=0[/tex]
Now, factorise it using the splitting-the-middle-term method .
[tex]9x^{2}+24x+16=0 \\9x^{2}+12x+12x+16 =0\\\left(9x^{2}+12x\right)+\left(12x+16\right)=0 \\3x\left(3x+4\right)+4\left(3x+4\right) =0\\\left(3x+4\right)\left(3x+4\right) = 0\\\left(3x+4\right)^{2} = 0[/tex]
Now since both the factors are the same, take one of them,
[tex]3x + 4 = 0\\3x = - 4\\\boxed{\bf\:x = -\frac{4}{3}}[/tex]

3. -0.5 and 0.5
Please hurry!!
Will award 30 points!!
Answer:
b) |y-11|=6
c) |z-1|=5
d) |a-0|=1/2
Step-by-step explanation:
This definetly works!
The absolute value equations are =
1) |x - 11| = 6
2) |x + 1| = 5
3) |x| = 0.5
1) To satisfy the solution set of 5 and 17 on a number line, we can write an absolute value equation as follows:
|x - 11| = 6
Explanation: The midpoint between 5 and 17 is 11, which serves as the value c in the equation.
The absolute value of x minus 11 should be equal to the distance between the midpoint and either endpoint, which is 6.
2) To satisfy the solution set of -4 and 6 on a number line, we can write an absolute value equation as follows:
|x + 1| = 5
Explanation: The midpoint between -4 and 6 is -1, which is the value c in the equation.
The absolute value of x plus 1 should be equal to the distance between the midpoint and either endpoint, which is 5.
3) To satisfy the solution set of -0.5 and 0.5 on a number line, we can write an absolute value equation as follows:
|x| = 0.5
Explanation: In this case, the midpoint between -0.5 and 0.5 is 0, which is the value c in the equation.
The absolute value of x should be equal to the distance between the midpoint and either endpoint, which is 0.5.

in 1990 there were about 5.4 billion people in the world. if the population has been growing at 1.95% per year, estimate the year when the population will be 8 billion people
Answer:
2011
Step-by-step explanation:
Here is the formula.
[tex]A=P(1+r)^{n}[/tex]
A = Final Value
P = Starting Value
R = Rate
N = Time in Years
A = 8,000,000,000
P = 5,400,000,000
R = 0.0195
N = Time in Years
Solve for n.
20.35 Years from 1990; so sometime in 2011 the population would be 8 billion.
There were 8 judges at a gymnastics competition. Kathleen received these scores for her performance on the uneven parallel bars.
8.9, 8.7, 8.9, 9.2, 8.8, 8.2, 8.9, 8.8
a. Find the mean, median, and mode.
b. Which statistic reflects a typical score? Explain.
Answer:
below
Step-by-step explanation:
mean : 8.8
The mean is the average, so you find it by adding all the numbers together and dividing by n, or how many numbers there are. For this, I added to get 70.4 and divided that by 8 (8 total scores).
70.4/8 = 8.8.
median : 8.85
The median is the middle of the data set, so you put the numbers in increasing order (lowest number to highest number) and then finding the middle of that set. For this set, since there is an even number of numbers (8), you have to find the middle by adding the two middle numbers and dividing by 2.
8.2, 8.7, 8.8, 8.8, 8.9, 8.9, 8.9, 9.2
The middle numbers are 8.8 and 8.9, so you add those together and divide by 2 to get 8.85.
mode : 8.9
The mode is just what number appears most often. Because 8.9 appears three times in this data set, more than any other number, the mode is 8.9.
b. The mean reflects a typical score because it is the average, and is used most often when someone is expressing a typical or "average" score. It is the score most people are likely to get, and as there are no outliers in this data set, it reflects a typical score for this data set. It is also the same as the mode, or most often score, in this data set.
1) Put the numbers in order
8.2, 8.7, 8.8, 8.8, 8.9, 8.9, 8.9, 9.2
2) mean is average
70.4/8 = 8.8
3) Median is the middle number; if m = 2, then divide them by 2
17.7/2 = 8.85
4) Mode is most often
8.9 (3 times)

1. a number is as much greater than 21 as it is less than 71. find the number
.
2. find 2 consecutive natural number whose sum is 63.
1. A number is as much greater than 21 as it is less than 71. Find the number
Solution -
Let the number be x.
x - 21 (number is as much greater than 21)71 - x (it is less than 71)As both the value of x - 21 and 71 - x is same hence,
=> x - 21 = 71 - x
=> x + x = 71 + 21
=> 2x = 92
=> x = 92/2
=> x = 46
Hence, the number is 46.
2. Find 2 consecutive natural number whose sum is 63.
Let the two consecutive numbers be x and x + 1.
=> x + (x + 1) = 63 (A.T.Q)
=> x + x + 1 = 63
=> 2x = 63 - 1
=> 2x = 62
=> x =62/2
=> x = 31
Hence, the consecutive natural numbers whose sum is 63 are 31 and 32.
