A city has a population of 2,549,786 people. Estimate this population to the nearest million. Express your answer as the product of a single digit and a power of 10. Rounded to the nearest million, the population is about? Written as the product of a single digit and a power of ten, this number is blank X 10 to the power of what?
Answers
Solution,
The population of a city is 2,549,786.
We can convert it into nearest million as follows :
Million = 10 lakhs
Rounding off to the nearest million
2,549,786 = 3,000,000
There are 6 zeroes after 3. We can express as the product of a single digit and a power of 10 as follows :
[tex]3,000,000=3\times 10^6[/tex]
Hence, the population of the city is 2,549,786 or [tex]3\times 10^6[/tex].

How to find the equivalent expression?Equivalent expressions are the expression whose result is equal to the original expression, but the way of representation is different.
To find the equivalent expression, simplify the provided function using the mathematical operations.
The given algebraic expression is,
[tex]\dfrac{5y^3}{(5y^{-2})}[/tex]
Suppose the equivalent expression of this fraction is n. Thus,
[tex]n=\dfrac{5y^3}{(5y^{-2})}\\\\n=\dfrac{5y^3}{((5)^{-2}y^{-2})}\\[/tex]
In the division the power of the same number is subtracted. Therefore,

5. If the number of employees is represented by x, which function represents the
amount each received?
a. f(x) = 65000x
b. f(x) = x + 65000
c. f(x)
d. f(x) = x - 65000
65000
Answers
Consider the missing lines of question are "Due to the Enhanced Community Quarantine, Grand Royal Spa temporarily stopped its operation and to help the employees, the owner decided to split evenly its total revenue of 65,000.00".
Given:
Total revenue = 65000
Number of employees = x
To find:
The function which represents the amount each received.
Solution:
We know that,
[tex]\text{Amount each received}=\dfrac{\text{Total revenue}}{\text{Number of employees}}[/tex]
Substitute the given values in the above formula.
[tex]\text{Amount each received}=\dfrac{65000}{x}[/tex]
So, the function which represents the amount each received is
[tex]f(x)=\dfrac{65000}{x}[/tex]
Therefore, the required function is [tex]f(x)=\dfrac{65000}{x}[/tex].

Heidi is riding her bike to visit a friend in another town. Her speed is inversely related to her travel time. If she is Charlie at 15 mph it will take her for hours to reach her destination. How long will it take her if she travels at 12 mph?
Answers
Step-by-step explanation:
I am not sure I understand the question with all the typos and potentially missing parts.
as I understand it, it will take her 4 hours to reach her destination when going 15 mph.
and the question is how long the trip will take, if she travels at 12 mph.
4 h × 15 m/h = 4 × 15 m = 60 miles
that is the distance of her trip.
when going slower, the distance is of course still the same, only the needed time changes :
x h × 12 m/h = 60 m
x × 12 m = 60 m
x = 60/12 = 5 hours
the trip would take her 5 hours to complete (instead of 4).
Which of the following shows the true solution to the logarithmic equation below? log (x) log (x 5) = log (6 x 12) x = negative 3 x = 4 x = negative 3 and x = 4 x = negative 3 and x = negative 4
Answers
The true solution to the logarithmic equation log(x)+log(x+5)=log(6x+12) is 4 option second is correct.
It is given the logarithmic equation [tex]\rm logx+log(x+5)=log(6x+12)[/tex].
It is required to find the true solution to the above logarithmic equation.
What is Logarithm?It is another way to represent the power of numbers and we say that 'b' is the logarithm of 'c' with base 'a' if and only if 'a' to the power 'b' equals 'c'.
[tex]\rm a^b=c\\[/tex]
[tex]\rm log_ac=b[/tex]
We have:
[tex]\rm logx+log(x+5)=log(6x+12)[/tex]
By using log property:
[tex]\rm logx + logy= log(xy)[/tex]
[tex]\rm log((x)(x+5))=log(6x+12)[/tex]
Taking [tex]\rm log_1_0[/tex] base and removing the log from the sides we get:
[tex]\rm x(x+5)= 6x+12\\\\\rm x^2+5x=6x+12\\\\\rm x^2-x-12=0[/tex]
It is quadratic equation solving by factorization method:
[tex]\rm x^2-x-12=0\\\\\rm x^2+3x-4x-12=0\\\\\rm x(x+3)-4(x+3)=0\\\\\rm (x+3)(x-4)=0\\\\\rm x+3=0 \ or \ x-4=0\\\\ \rm x=-3 \ or \ x=4\\\\[/tex]
A negative Logarithm value does not exist.
Hence, the true solution to the logarithmic equation log(x)+log(x+5)=log(6x+12) is x = 4

The null hypothesis can only be rejected whether there is enough statistical data than that of the critical values.
The options A and B are not accurate, because the mean test of around 80 means that now the check-in and check number is lower, giving small statistics of the experiment and resulting in the null hypothesis is not rejected. In the C or D is true, however, the importance or alpha level need to be tested Alpha level 0.05 is 5% likely to reject an absolute zero hypothesis so, although 0.01 alpha level is 1% more likely to oppose an absolute zero hypothesis, Therefore, the alpha 0.05 rating is stronger.A triangle has two sides of length 6 and 12.

Answers
Answer:
No, the correct answer is 32cm.
Step-by-step explanation:
First of all, lets cut the shape into two. A rectangle and a triangle. This will help us find the slanted side of the shape.
We will use the pythagorean theorem to find the length of the slanted line.
The pythagorean theorem is [tex]a^{2} +b^{2} =c^{2}[/tex].
Input the given information of the triangle lengths that we know; that is the length= 6 and the base=3.
[tex]c= \sqrt{a^{2}+b^{2} } =\sqrt{6^{2}+\ 3^{2} } = 6.7082[/tex]
Now, we round.
6.7082≈ 6.7
We have found the length of the slanted line of the shape.
Now, let's add all the lengths together.
8+6+6.7+11= 31.7
Now, lets round.
31.7 ≈ 32cm
