We would divide the mass of the sun by the mass of the earth. From the information given,
mass of earth = 5.972 x 10^24
mass of sun = 1.61244 x 10^31
Number of earths = 1.61244 x 10^31/5.972 x 10^24 = 2.7 x 10^6
It will take 2.7 x 10^6 to equal the mass of the sun

Given: 18 is 32% of a number
To Determine: The number
Let the number be w. Therefore:
[tex]\begin{gathered} 32\%ofw=18 \\ \frac{32}{100}\times w=18 \end{gathered}[/tex][tex]\frac{32w}{100}=18[/tex][tex]\begin{gathered} 0.32\times w=18 \\ 0.32w=18 \end{gathered}[/tex]Divide both sides by 0.32

[tex]undefined[/tex]Bethany is paid time-and-a-half for each hour she works above her normal 40 hours each week. Last week, Bethany worked 44 hours and her gross pay was $575. how much did Bethany earn for each hour of overtime she worked?
Answers
Bethany worked a total of 44 hours, which means that she worked 40 normal hours and 4 extra hours.
Let x be the amount earned per 1 normal working hour since she earns a half more for each extra hour we can express the money earned above her 40 normal hours as 1.5 times x ( x+0.5*x = 1.5x), then we can express the gross pay like this:
gross pay = earnings per normal hour * normal hours + earnings per extra hour * extra hours
gross pay = x * normal hours + 1.5x * extra hours
As mentioned, she worked 40 normal hours and 4 extra hours, then we get:
gross pay = x*40 + 1.5x*4
gross pay = 40x + 1.5*4x
gross pay = 40x + 6x
gross pay = 46x
From the given information, we know that the gross pay equals $575, then we get:
575 = 46x
46x/46 = 575/46
x = 575/46
x=12.5
The amount earned with extra hours is 1.5x, then we get:
Extra hour earning = 1.5*12.5=18.75
Then, Bethany earned $18.75 for each extra hour

I need help to determine weather the slope on this graph is A. ZeroB. Negative C. Positive
Answers
The slope usually indicates the behavior of a line:
In the above picture there are 3 different lines with different slopes, let's describe them:
-L1. This red line has a positive slope, it means that as "x" increases, then "y" increases as well.
-L2. This blue line has a negative slope, which means that as "x" increases, then the value of "y" decreases.
-L3. This green line is horizontal and has zero slope . This means that it doesn't matter the value of "x", "y" always has the same value.
Using this description, we can now assure that the slope in your graph is NEGATIVE

What is Equation of line?The equation of line passing through the points (x₁ , y₁) and (x₂, y₂) with slope 'm' is defined as;
y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
The graph for the equation of line is shown in figure.
Now,
Take two points on the line of the graph.
Two points are ( 1, 2) and (2, 4)
Find the slope of the line with two points (1, 2) and (2, 4) as;
⇒ m = (4 - 2) / (2 - 1)
⇒ m = 2 / 1
⇒ m = 2
Thus, The equation of line passing through the points (1, 2) and (2, 4) with slope 2 is;
⇒ y - 2 = 2 ( x - 1 )
⇒ y - 2 = 2x - 2
⇒ y = 2x - 2 + 2
⇒ y = 2x
Therefore,
The equation of line will be;
⇒ y = 2x
