Trudy bought a $20 prepaid long distance phone card. for every minute that she talks, $0.25 is deducted from her card. The function f(m)=20-0.25m represents the amount of money f(m) she has left after talking m minutes.FInd the zero and explain what it means in the context of the situation.
Answer:
Step-by-step explanation:
Given the function f(m)=20-0.25m to represent the amount of money f(m) she has left after talking m minutes, the zero of the equation can be gotten by setting f(m) to 0
f(m)=20-0.25m
0 =20-0.25m
-20 = -0.25m
m = -20/-0.25
m = 80
Hence Trudy will have talked for 80minutes if she has no money left
A town’s population of children increased from 376 to 421 during the past year.
Which equation shows how to find the percent increase?
p=421−376376
p=421−376421
p=376421−376
p=376+421376
Answer: B
Step-by-step explanation:
Answer: see explanation
Step-by-step explanation:
percent increase = × 100%
the increase = 421 - 376 = 45, hence
percent increase = × 100% ≈ 12%

Annie needs $30 to buy a coat she has saved $12 and plans to work as a baby siter to earn $6 per hour which inequality shows the minimum number of hours, n, that annie should work as a babysitter to earn enough to buy a coat?
a 12 + 6n ≤ 30, so n ≤ 3
b 12 + 6n ≥ 30, so n ≤ 3
c 6n ≥30 + 12, so n ≥ 7
d 6n ≤30 + 12, so n ≤ 7
Answer:
The answer would be B.
Step-by-step explanation:
This is because the total cost is $30 so it can't be c or d. A shows that Annie can only have at least $30. this means that B is the only option left.
If this answer is wrong, I deeply apoligize. I hope you have a great day.

A parent is using a garden hose to fill up a small inflatable pool for her young child. The pool has a capacity of 90 gallons. She turns the water off after 5 minutes, but leaves the hose in the pool for another 3 minutes before putting it away.
In this situation, the relationship between the gallons of water in the pool and the 8 minutes since the parent started filling the pool can be seen as a function.
In that function, which variable is independent? Which one is dependent?
Type your response in the space below.
Answer:
Independent variable = the time. Dependent variable = amount of water per minute
Step-by-step explanation;
The total amount of water depends on how long the hose is left on.
The relationship between the gallons of water in the pool and the 8 minutes since the parent started filling the pool can be seen as a function is ''the total amount of water depends on how long the hose is left on''.
Time is the independent variable.
The amount of water per minute is the dependent variable.

A parent is using a garden hose to fill up a small inflatable pool for her young child.
The pool has a capacity of 90 gallons.
She turns the water off after 5 minutes but leaves the hose in the pool for another 3 minutes before putting it away.
What is the independent variable?Independent variables are the variables that the experimenter changes to test their dependent variable.
What is the dependent variable?A change in the independent variable directly causes a change in the dependent variable.
1. The relationship between the gallons of water in the pool and the 8 minutes since the parent started filling the pool can be seen as a function is ''the total amount of water depends on how long the hose is left on''.
2. Time is the independent variable.

why wuld 8/4 be considerd a whole number
Answer:
because 8/4=2
Step-by-step explanation:
4/4=1
8/4=2
it's because the numerator is bigger if it were 6/4 it would be a mixed number but the eight goes in to 4 directly 2 time so therefore it's 2.
If 45% of a number is 63 and 35% of the same number is 49, find 80% of that number.
Answer:
Step-by-step explanation:
1) Let the number be y
45%of y=63
45y/100=63
Y=6300/45
Y=140
So 80%of a number =80y/100
=80×140/100
=112.
Let the number be y
35%of y=49
35y/100=49
Y=4900/35
Y=140
So 80%of a number =80y/100
=80×140/100
=112.
Is 5/6 equal to 2/3?
=====================================================
Work Shown:
For now, let's assume they are equal. We'll show a contradiction happens.
5/6 = 2/3
5*3 = 6*2 ... cross multiply
15 = 12 ... here's the contradiction
If the original equation was true, then we would get the same thing on both sides in the final step shown above. However, we get a contradiction, so that means the original equation is false.
Furthermore, the left side is larger in the third step, so the left side is larger for each of the three steps. We can then say
5/6 > 2/3
5*3 > 6*2
15 > 12
Which helps show 5/6 is larger than 2/3.
---------------------
Or you can use a calculator to see that
5/6 = 0.833 approximately
2/3 = 0.667 approximately
which shows the two fractions aren't equal and 5/6 is larger.

find the area of the regular hexagon PQRSTU of sides 8 cm as shown in the figure
Answer:
Area = 245m^2
Step-by-step explanation:
We can split this figure into 2 parts, a rectangle and a trapezoid.
Rectangle Sides = 10m and 20m
Area = 10m x 20m = 200m
Trapezoid formula = a+b/2(h)
a and b are the 2 bases and h is the height
Using a little deductive reasoning we get the following, 5+10/2(6)
This simplifies to 15/2(6) -->
7.5(6) = 45
Thus, our area is 200 + 45, or 245m^2

9514 1404 393
Answer:
see below
Step-by-step explanation:
Starting from the point-slope equation ...
y -y1 = m(x -x1)
Solving for y gives ...
y = mx +(y1 -m·x1)
So, the slope-intercept form equation is fairly easily found:
y = mx +b . . . . where m = m, and b = y1-m·x1
This is the equation we have used for 'b' in the attached spreadsheet.
__
Of course, the formula for slope is ...
m = (y2 -y1)/(x2 -x1)
This is the equation we have used for 'm' in the attached spreadsheet. For all problems, we have used the first point. (It doesn't matter which point you use if there are two of them.)
__
The second attachment is the Google Sheets spreadsheet saved in ODS format. Most spreadsheet programs should be able to open that so you can see the formulas, if you're interested. (The gray values of m are computed using the two points. The unshaded values of m are entered by hand.)
_____
I'll write a couple of equations in each group so you can see how the spreadsheet numbers relate:
y = mx +b
1. y = 2x -7
3. y = 2/3x +4
8. y = 1/3x -5
9. y = -5/2x +4

What is the slope of the line through -4,3 and 5,3
Answer:
slope = 0
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 4, 3) and (x₂, y₂ ) = (5, 3)
m = [tex]\frac{3-3}{5+4}[/tex] = [tex]\frac{0}{9}[/tex] = 0

The value of the function f (x) is 15/2 when x = -5 and is -73/2 when x = 3. What is the equation of the function?
Answer:
y = -5.5x - 20
Step-by-step explanation:
There are many functions that cross those points.
Assuming you're looking at a straight line.
y = mx + b
15/2 = -5m + b --> 7.5 = -5m + b
-73/2 = 3m + b --> -36.5 = 3m + b
Subtract the first from the second.
-44 = 8m
m = -5.5
Plugging back into the first equation, we get b = -20

f(x) = −11/2x − 20

A flat-screen television was marked down by 35 percent, which reduced its price by $115.65. What was the original cost of the television before it was marked down?
$214.78
$330.43
$404.78
$4,047.75
Answer:
B
Step-by-step explanation:
35% of this price is :
35/100 × x = 0.35x
The price reduces by 0.35x.
This equals to 115.65
Now :
0.35x = 115.65
