The scientific notation of the given 0.0123 will be 123 x 10^{-4}.
How does scientific notations work?The number is written in the form a x 10^b.
The number b shows the order, which is the most important figure for which scientific notation is used. It tells us how much order large or small a value is in powers of 10.
We can for a time, ignore the value of 'a' for two comparable quantities and only compare their orders(this type of comparison is useful when difference is too big, like size of human to size of a star etc sort of comparisons).
Scientific notations have some of the profits as Better readability due to compact representation.
Its value in terms of power of 10 is known, which helps in easy comparison of quantities differing by a large value.

The difference between the two square roots of a whole number is about 5.3 what is the number
The difference between the two square roots of a whole number cannot be about 5.3.
Explanation:The difference between the two square roots of a whole number can be expressed as:
sqrt(x) - sqrt(x) = 5.3
Since the square root of a number multiplied by itself gives the number, we can rewrite the equation as:
x - x = 5.3
This simplifies to:
0 = 5.3
However, this is not possible, as it would mean that 0 is equal to a non-zero value. Therefore, there is no whole number that satisfies the given condition.

A swimmer swam the 50-meter freestyle in a time of 21 seconds. What was the speed to the nearest tenth of a meter per second?
The answer would be 2.4 meters per second. To find this, you would divide the 50 meters by 21 seconds. It equals 2.380952, and rounds to 2.4m/s.
Answer:
2.4 meter per second
Step-by-step explanation:
A swimmer swam the 50-meter freestyle in a time of 21 seconds.
Since a swimmer swam in 21 seconds = 50 meters
To calculate his speed in 1 second we will divide the total distance by the total time.
Therefore, he swam in 1 second = [tex]\frac{50}{21}[/tex]
= 2.380952 rounded to 2.4 meter/sec
The speed of the swimmer is 2.4 meter per second.

8/2 - 7/12 What is the answer
Firstly find the common denominator (12) so for 2 to turn into 12 it needs to be multiplied by 6. Because of this, 8 also needs to be multiplied by the same amount so the first fraction would be 48/12.
The second fraction doesn't need to be changed so...
48/12 - 7/12 = 41/12.

(b) For the unit rate (i.e. rate of change per time - minutes in this case) we can simply divide the total water pumped out by the total time it took to perform this. So: 48 ÷ 8 = 6 gallons/min.

Note the equal sign. What you do to one side, you do to the other.
Also, remember to do the opposite of PEMDAS.
First, subtract 6 from both sides
-2x + 6 (-6) = -20 (-6)
-2x = -26
Next, isolate the x. Divide -2 from both sides
(-2x)/-2 = (-26)/-2
x = -26/-2

Which of the following is the radical expression of a to the four ninths power ?
A. 4a9
B. 9a4
C. fourth root of a to the ninth power
D. ninth root of a to the fourth power
Given expression in exponential form : [tex]a^{\frac{4}{9} }[/tex].
We need to convert it into radical form.
Please note: When we convert an exponential to radical form, the top number goes in the exponent of the term and bottom number of the fraction goes in the radical sign to make it nth radical.
We can apply following rule:
[tex](a)^{\frac{m}{n}}= \sqrt[n]{x^m}[/tex].
Therefore,
[tex]a^{\frac{4}{9} }= \sqrt[9]{a^4}[/tex].
Therefore, correct option is : D. ninth root of a to the fourth power.

Find the nonpermissible replacement for N in the following expression :
-8/5n
We are given expression
[tex]\frac{-8}{5n}[/tex]
we know that
this is rational expression
And any rational expression is undefined when it's denominator =0
so, for finding non-permissible values of n , we set denominator =0
and then we can solve for n
denominator is 5n
[tex]5n=0[/tex]
Divide both sides by 5
[tex]\frac{5n}{5} =\frac{0}{5}[/tex]
so, we get
[tex]n=0[/tex]
So, the non-permissible replacement for n in this expression is 0.........Answer
The correct answer is
[tex]n=0[/tex]
[tex] EXPLANATION [/tex]
This is testing your knowledge on domain of rational functions.
To avoid division by zero, the denominator of the rational function
[tex]\frac{-8}{5n}[/tex]
should not be equal to zero.
Therefore the non permissible number can be found by equating the whole denominator to zero. That is,
[tex]5n=0[/tex]
We can now solve for n, to obtain,
[tex]n=\frac{0}{5}=0[/tex]
Hence that number is
[tex]n=0[/tex]

Fran buys socksAnd packages that contain nine pairs of white socks for every three pairs of blue socks Mia buy socks and packages with the ratio of two blue pairs do you for white pairs if the girls each bought six pairs of blue song how many pairs of white socks would they each have bought
Answer: Number of white socks Fran has =18
Number of white socks Mia has = 9
Step-by-step explanation:
Since we have given that
Fran buys socks in such a way that it contains nine pairs of white socks for every three pairs of blue socks i.e.
Ratio becomes
[tex]9:3=3:1[/tex]
Similarly,
Mia buys socks and packages in such a way that it contains two blue pairs for every one white pair
So, ratio becomes
[tex]2:1[/tex]
Now, from the case of Fran, we have given that she has 6 pairs of blue socks .
So, we get that
[tex]\frac{1}{4}\times x=6\\=x=24\\\\\text{So, number of white socks becomes }=\frac{3}{4}\times 24=\frac{72}{4}=18[/tex]
Similarly,
From the case of Mia , we have given that she has 6 pairs of blue socks .
we get that
[tex]\frac{2}{3}\times y=6\\y=9\\\\\text{So, number of white socks Mia has }=\frac{1}[3}\times 9=3[/tex]
So, Number of white socks Fran has =18
Number of white socks Mia has = 9
Final answer:
Fran would have bought 18 white pairs of socks and Mia would have bought 12 white pairs, given their purchase of 6 pairs of blue socks and based on their respective ratios of white to blue socks in a package.
Explanation:
To answer the student's question, we must understand the concept of ratios. Fran buys socks in a package with a ratio of 9 white pairs to 3 blue pairs. Mia buys socks in a package with a ratio of 2 blue pairs to 4 white pairs. If each girl bought six pairs of blue socks, we'll calculate how many white socks they would have bought by setting up a proportion corresponding to each of their packages' ratios.
For Fran: The ratio 9:3 simplifies to 3:1 (since for every three pairs of white socks, there is one pair of blue socks). So for every blue sock pair, there are three white. Therefore, if Fran buys 6 blue pairs, she would buy 6 * 3 = 18 white pairs.
For Mia: The ratio 2:4 simplifies to 1:2. So for every two pairs of white socks, there is one pair of blue socks. Therefore, if Mia buys 6 blue pairs, she would buy 6 / 1 * 2 = 12 white pairs.

find the value of each variable
x=38, y=76
x=52, y=76
x=38, y=104
x= 52, y= 104
Answer: The correct option is
(C) x = 38 and y = 104.
Step-by-step explanation: We are given to find the values of the variables x and y from the figure.
We know that
if two angles make a linear pair, then the sum of their measures is 180°.
From the figure, we note that
the angles with measures y° and 76° makes a linear pair, so we have
[tex]y^\circ+76^\circ=180^\circ\\\\\Rightarrow y+76=180\\\\\Rightarrow y=180-76\\\\\Rightarrow y=104.[/tex]
Also, the angles with measures 2x° and y° makes a linear pair, so we have
[tex]2x^\circ+y^\circ=180^\circ\\\\\Rightarrow 2x+y=180\\\\\Rightarrow 2x=180-104\\\\\Rightarrow 2x=76\\\\\Rightarrow x=\dfrac{76}{2}\\\\\Rightarrow x=38.[/tex]
Thus, the required values the variables are x = 38 and y = 104.
Option (C) is CORRECT.
Answer please? ___ feet per second
Answer: 30 feet per second
========================================
x = diameter, y = speed of water
y varies inversely with respect to x, so, y = k/x for some constant k
If x = 0.6 and y = 5 pair up, then y = k/x turns into 5 = k/0.6 which solves to k = 3 when you multiply both sides by 0.6
So the equation y = k/x turns into y = 3/x
Now plug in the diameter x = 0.1 to find the speed to be...
y = 3/x
y = 3/0.1
y = 30 feet per second
