96 million
Step-by-step explanation:
48/6= 8
8*12 million = 96 million
MARKING BRAINLIEST IF U HELP 19 - s = 13; s = -6 yes no question
Answer:
Step-by-step explanation:
We have the equation 19 - s = 13, and are asked to determine whether s = -6 fits in.
To solve, we need to isolate "s", do as followed and subtract 19 from both sides :
s = -6
Since this is equal to what the question is asking, yes s = -6 is correct.

Determine the equation of the line that passes through (2,-3) and (1,-6). Explain how you got your answer.
Answer:
y = 3x - 9
Step-by-step explanation:
Let's start by finding the slope of the line:
The formula for slope is [tex]m = \frac{y_1 - y_2}{x_1 - x_2}[/tex].
Plug in the numbers and solve:
[tex]m = \frac{y_1 - y_2}{x_1 - x_2}[/tex]
[tex]m = \frac{-3 - (-6)}{2 - 1}[/tex]
[tex]m = \frac{3}{1}[/tex]
[tex]m = 3[/tex]
The slope of the line is 3.
The slope intercept form of a line is y = mx + b, where m is the slope and b is the y coordinate of the y-intercept.
Plugging in the number we got for the slope, the equation becomes:
y = 3x + b
Let's solve for b by plugging in an ordered pair for y and x:
y = 3x + b
-3 = 3(2) + b
-3 = 6 + b
b = -9
The y-coordinate of the line is (0, -9).
Now, plugging in the number into our equation, we get:
y = 3x + (-9)
y = 3x - 9
And that's the equation of the line!
I don't understand how to solve this
Answer:
7 and 5 are congruent
Step-by-step explanation:
which pair of angles is congruent meaning which pair of angles is the same when looking at the angles given angles 5 and 7 are the same
Consider this equation.
cos(θ) = 4sqrt41/41
If θ is an angle in quadrant IV, what is the value of sin(θ) ?
Answer:
A. -5√41/41Step-by-step explanation:
Let the horizontal leg = 4√41 and the hypotenuse = 41 as
cosine = adjacent leg / hypotenuse.Then the vertical leg is:
√(41² - 16*41) = √25*41 = 5√41Since the vertical leg is below the x-axis, its value is -5√41
Then we have:
sin (θ) = -5√41/41Correct choice is A

A company charges a shipping fee that is 4.5% of the purchase price for all items it ships. What is the fee to ship an item that costs $70? Round to the nearest cent (hundredths place).
Answer:
3.15 cents
Step-by-step explanation:
So, lets go over all the information we know.
First off, we know that the cost of the item is 70 dollars.
Secondly, we know that the fee is 4.5% of 70 dollars.
Now, what is 4.5%?
Well, we know that 100% is qual to 1.
So lets divide 4.5 by 100, which is just moving the decimal point back by 2:
0.045
Now, the last thing to do is multiply 0.045 by 70.
0.045x70
=
3.15
So now we know the fee for a 70 dollar item is 3.15 dollars!
Hope this helps ;)

Find the area of the regular hexagon round answer to the nearest tenth.
Answer:
280.6 [tex]m^2[/tex]
Step-by-step explanation:
find the length of each side:
you're only given h = 9 m
the formula for h is [tex]h=\frac{\sqrt{3} }{2} *a[/tex], where a is a side length of the hexagon
plug h in:
[tex]9=\frac{\sqrt{3}}{2}*a\\\\a=9*\frac{2}{\sqrt{3}}\\\\[/tex]
a ≈ 10.392 m
now find the area of a triangle:
1/2 (10.392)(9) = 46.764 [tex]m^2[/tex]
multiply that by 6 and you get 280.584 ≈ 280.6 [tex]m^2[/tex]
you can also use the regular hexagon area formula instead of finding the individual area and multiplying by 6: [tex]\frac{3\sqrt{3} }{2} *a^2[/tex]

The table shows the percentage of students in each of three grade levels who list soccer as their favorite sport.
Soccer
Sophomores (35%) 50%
Juniors (33%) 45%
Seniors (32%) 30%

The binomial (x + 5) is a factor of x2 + 8x + 15. What is the other factor? (x + 3) (x + 7) (x + 12) (x + 13)
Answer: [tex]x+3[/tex]
Step-by-step explanation:
Given
[tex](x+5)[/tex] is a factor of [tex]x^2+8x+15[/tex] , that is
If [tex]x^2+8x+15[/tex] is divided by [tex](x+5)[/tex], it yields 0 remainder
Solve the quadratic equation
[tex]\Rightarrow x^2+8x+15=0\\\Rightarrow x^2+3x+5x+15=0\\\Rightarrow (x+3)(x+5)=0\\\Rightarrow x=-3,-5[/tex]
Therefore, [tex]x+3[/tex] is another factor of the quadratic equation.
