How to convert 1 million seconds to hours
Solution
Step 1
To convert seconds to hours, divide the seconds by 3600.
Step 2
1 million seconds = 1000000 seconds
[tex]\begin{gathered} To\text{ hours} \\ \\ \text{= }\frac{1000000}{3600} \\ \\ =\text{ }277\frac{7}{9}\text{ hours} \end{gathered}[/tex]factor out the coefficient of the variable term 4x-20
the given expression is,
4x - 20 = 0
here 4 is the coefficient of variable x
4x = 20
x = 20/4
x = 5

Which describes how to find all rotation angles less that 360° that will map a regular polygon onto itself?
This question is about rotations of polygons.
To rotate a polygon onto itself, we need to know the exact rotation we have to do. This rotation depends on the type of polygons, specifically, the number of sides.
To know the exact angle rotation to map the polygon onto itself, we just have to divide 360° by the number of sides.
Therefore, the right answer is the third choice.Answer:

Answer:
FOIL Method! (EXPLAINED BELOW)
Step-by-step explanation:
FOIL MEANS First Out In Last.
For example:
Binomial: (a+b) (a+b)
STEP 1: Multiply the first term of each bracket.
(a+b) (a+b)
So, a * a = [tex]a^{2}[/tex]
The number would be positive since both terms are positive.
STEP 2: Multiply the outer terms.
(a+b) (a+b)
So, a * b = ab
The number would be positive since both terms are positive.
STEP 3: Multiply the inner terms.
(a+b) (a+b)
So, a * b = ab
The number would be positive since both terms are positive.
STEP 4: Multiply the last terms.
(a+b) (a+b)
So, b * b = [tex]b^{2}[/tex]
The number would be positive since both terms are positive.
STEP 5: Put them together with the appropriate signs.

Which is the domain and range of the parabola with the equation y = 0.5(x²-10x-5)?
The domain of the given function is the set of all real numbers that is represented as x ∈ (-∝,∝ ) and range of the function is [-15,∝).
What is domain and range of a function?The set of values that can be plugged into a function is known as its domain. The range of a function is the collection of all potential values that can result from the dependent variable, or the collection of all possible values after substituting the domain.
Domain of a polynomial function is the set of all real numbers which is given by x ∈ (-∝,∝ ).
Since the given function y = 0.5(x^2 - 10x - 5) is a polynomial function, it's domain is x ∈ (-∝,∝ ).
To obtain the range of the function, plot the graph of the parabola which is shown in the figure.
The vertex of the parabola is at (5,15). Value of y does not go below 15. Therefore the set of all possible values that the function takes is given by [-15,∝).

What is the slope of the line that contains the points (-3, -4) and (-6, 2)?
The slope of the line that contains the (-3, -4) and (-6, 2) is -2.
How to find the slope of a line?The slope of a line is the change in the dependent variable with respect to the change in the independent variables.
The slope is refer to as rise over run.
Therefore, the slope of the line that contains the points (-3, -4) and (-6, 2) can be found as follows:
slope = y₂ - y₁ / x₂ - x₁
where
x₁ = - 3
x₂ = - 6

-6.4 > 0.8*b
-6.4/0.8 > b
-8 > b

What is division ?Division is the opposite of multiplication. If you divide 12 into three equally sized groups, you will get four in each group if the three groups of four sum up to 12, which they do when you multiply. The main goal of division is to count the total number of evenly distributed groups or the total number of people in each group following a fair distribution.
CalculationLet's calculate how many pages each person reads in one day:
Jayson ⇒ 48 pages / 3 days = 16 pages/dayMarcus ⇒ 50 pages / 4 days = 12.5 pages/dayNina ⇒ 120 pages / 5 days = 24 pages/dayThen we divide the number of pages of each book by reading speed of the respective person:
Jayson ⇒ 480 pages ÷ 16 pages/day = 30 daysMarcus ⇒ 400 pages ÷ 12.5 pages/day = 32 daysNina ⇒ 600 pages ÷ 24 pages/day = 25 daysThus Nina will take the shortest time finishing her book.
