[tex]\boxed {\boxed {\sf C. \ 4 \ inches}}[/tex]
Step-by-step explanation:
Circumference is the perimeter of a circle. It can be found using the formula:
[tex]c= \pi d[/tex]
However, we are given the radius.
The radius measures from the center to the edge of the circle. The diameter measures from edge to edge through the center. So, the diameter is twice the radius, or d=2rThe formula can be rewritten as:
[tex]c= \pi 2 r[/tex]
We know the circumference is 25.12 inches.
[tex]25.12 \ in = \pi 2r[/tex]
Let's round pi to 3.14
[tex]25.12 \ in = (3.14) 2r[/tex]
We want to solve for the radius, so we must isolate it.
Divide both sides by 3.14 because the inverse of multiplication is division.
[tex]25.12 \ in / 3.14= (3.14 ) 2r / 3.14[/tex]
[tex]8 \ in = 2r[/tex]
Divide both sides by 2.
[tex]8 \ in / 2 = 2r/2[/tex]
[tex]4 \ in = r[/tex]
The radius of the disc is 4 inches.

root -24
break up into two parts:
root 24 and root -1
root -1 always = i
so now we have root 24 and i
now break up root 24
which is root 4 and root 6
root 4 is a perfect square so we can take it out and put it with the 3 we put aside earlier
but when we take it out we have to remember to solve the root
so root 4 becomes 2
we are left with root 6 and i this doesn’t get any smaller
multiply the 3 and 2 we grouped together and we get:
6 root 6i

10. Write the equation of the line that is parallel tox-3y = 9 and passes through the point (3,-1).
Answers
Answer:
Equation of the line that is parallel tox-3y = 9 and passes through the point (3,-1) is
[tex]y+1= - \frac{1}{3} (x-2)[/tex]
Step-by-step explanation:
Slope of line x-3y = 9 is -1/3
Since Parallel lines have same slope. Therefore slope of line passing through the point (3,-1) is also -1/3.
Equation of line in point slope form is given as
[tex]y-y_1=m(x-x_1)[/tex] ---------- (1)
Here
[tex]m=-\frac{1}{3} \ \ and \ \ (x_1, y_1)= (3, -1)[/tex]
substituting values in equation (1)
[tex]y+1= - \frac{1}{3} (x-2)[/tex]

Step-by-step explanation:
If q is the quantity of cereal in the box before Heba ate some, the problem tells us ...
q - 1/12 = 3/4
q = 3/4 + 1/12 = 9/12 + 1/12 = 10/12
q = 5/6
There was 5/6 of a box before Heba ate.

The sum of two numbers is 55. Twice the lesser number is 5 more than the greater number. Find both numbers.
Answers
Answer:
x = 20 and y = 35
Step-by-step explanation:
So let's say that the two numbers are represented by x and y.
Firstly, the sum of the two is 55, so:
x + y = 55
Secondly, twice the lesser number is 5 more than the greater number, so, assuming x is lesser:
2x = y + 5
Let's isolate y in the second equation:
y = 2x - 5
We can substitute this into the first equation:
x + (2x - 5) = 55
Now we solve for x:
3x - 5 = 55
3x = 60
x = 20
Now that we know what x is, let's substitute that into the first equation and solve for y:
(20) + y = 55
y = 35
Therefore, x = 20 and y = 35
Hope this helps!

c.) [tex]y=\frac{4}{x+6}+7[/tex]
d.) [tex]y=\frac{4}{x-7}+6[/tex]
Answers
______________________________
1.) Substitute x, y, and general form using the formulas: Formula for x: [tex]x=d=7[/tex]Formula for y: [tex]y=k=6[/tex]Formula for general form y: [tex]y=\frac{a}{x-d}+k=y=\frac{4}{x-7}+6[/tex]
Note:
- When doing problems like this, it's best to list out each formula and do the drag down method, and replace methods rather than doing it the entire mathematical way, as doing it that way takes a long time and it's more confusing than it should be.
Equation at the end of Step 1:
[tex]y=\frac{4}{x-7}+6[/tex]2.) Simplify the d and k forms:[tex]y=\frac{4}{x-7}+6=y=\frac{4}{x-7}+6[/tex]
Note:
- The x(d) stays the same since the 7 was positive and we plugged it in making it negative, so it doesn't need to be changed. (Another way to know if you need to change it is if the original [tex](d)[/tex] or [tex](k)[/tex] when plugged in, you had to put them in parenthesis then most likely it needs to be changed.
- The y(k) stays the same since the 6 was positive and we plugged it, keeping it positive so it doesn't need to be changed. (Another way to know if you need to change it is if the original [tex](d)[/tex] or [tex](k)[/tex] when plugged in, you had to put them in parenthesis then most likely it needs to be changed.
So the answer is d, [tex]\bold{y=\frac{4}{x-7}+6}[/tex].

Answer:
[tex]y = -2x + 6[/tex]
Step-by-step explanation:
Given
[tex](x_1,y_1) = (1,4)[/tex]
[tex](x_2,y_2) = (2,2)[/tex]
Required
Determine the line equation
First, we calculate the slope (m) using
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{2-4}{2-1}\\[/tex]
[tex]m = \frac{-2}{1}[/tex]
[tex]m = -2[/tex]
The equation is then calculated using:
[tex]y - y_1 = m(x - x_1)[/tex]
[tex]y - 4 = -2(x - 1)[/tex]
Open bracket
[tex]y - 4 = -2x + 2[/tex]
[tex]y = -2x + 2 + 4[/tex]
[tex]y = -2x + 6[/tex]

eddie drinks 12 ounces of water before running and then another 8 ounces each time he runs a mile. Find the number of miles he runs each day if he drinks less than 60 ounces of water when he runs.
Answers
Answer:
x>6
Step-by-step explanation:
Your equation would be set up like so:
Y= 8X+12
Then plug in your Y value
60 > 8x+12
Subtract 12
48 > 8x
Divide by 8
x > 6
He runs less than 6 miles a day if he drinks less than 60oz of water. If he drank 60oz TOTAL, he would have run 6 miles TOTAL. (hence why there's no equal sign).
