Tony makes a phone call at a pay phone. The charge is 25 cents for the first four minutes,
and 10 cents for each additional minute. Tony has $2.10 in change in his pocket. Write an
inequality that can be used to find m, the maximum number of minutes that Tony can talk
on the phone. Solve this inequality algebraically to find the maximum number of whole
minutes he can talk on the phone.
Answer:
it would be a max of 22 mins
Step-by-step explanation:
25C=4 mins
10C*10 mins =1$
$1.25
2.10-1.25=.85
10C*8=80C
so
4+10+8=22
Tony can talk for a maximum of 22 minutes on the phone which is determined by the inequality 0.25 + 0.10 (x-4) ≤ 2.10.
What is inequality?Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.
According to the given question, we can write the inequality would be as:
⇒ 0.25 + 0.10 (x-4) ≤ 2.10
x = an integer number of minutes.
Subtraction is required since the first four are covered by the 0.25 price. Because fractional minutes count as a full minute, an integer is required.
⇒ 0.25 + 0.10x -0.40 ≤ 2.10
⇒ -0.15 +0.10 x ≤ 2.10
⇒ 0.10x ≤ 2.25
⇒ x ≤ 2.25 /0.10
⇒ x ≤ 22.5 ≈ 22
Therefore, the maximum number of whole minutes will be 22 minutes.

If point S is located at (0, 0), point T is located at (0, 6), point U is located at (12, 0), and point V is located at (0, 10), what are the coordinates of point W that makes △STU ~ △SVW?
A. (0,20)
B. (0,24)
C. (20.0)
D.(24,0)
Answer:
The coordinates of the point W is ((5/9)·√65, -20/9)
Step-by-step explanation:
The given parameters are;
The location of point S = (0, 0)
The location of point T = (0, 6)
The location of point U = (12, 0)
The location of point V = (0, 10)
We have;
The length of segment ST = √((6 - 0)² + (0 - 0)²) = 6
The length of segment SU = √((12 - 0)² + (0 - 0)²) = 12
The length of segment TU = √((12 - 0)² + (10 - 0)²) = √(144 + 100) = 2·√(61)
The length of segment TU = 2·√(61)
The length of segment SV = √((10 - 0)² + (0 - 0)²) = 10
Therefore, we have for similar triangles;
SV/SU = SW/ST = UW/TU
Therefore;
SW = ST × SV/SU = 6 × 10/12 = 5
VW = TU × SV/SU = 2·√(61) × 10/12 = (5/3)·√(61)
Where the coordinates of the point W = (a, b), we have;
Length of VW = √((10 - b)² + (0 - a)²) = (5/3)·√(61)
(25/9)·(61) = (10 - b)² + a²
Length of SW = √((0 - b)² + (0 - a)²) = 5
25 = b² + a²
∴ a² = 25 - b²
Substituting the value of a² into the length of segment LW equation, gives;
(25/9)·(61) = (10 - b)² + a² = (10 - b)² + 25 - b²
(25/9)·(61) = (10 - b)² + 25 - b² = 100 - 20·b + b² + 25 - b²
(25/9)·(61) = 125 - 20·b
20·b = 125 - (25/9)·(61)
b = -20/9
a² = 25 - b² = 25 - (-20/9)² = 1625/81
a = √(1625/81) = (5/9)·√65
The coordinates of the point W = ((5/9)·√65, -20/9).

What’s the constant rate of change
Answer:
1:5
Step-by-step explanation:
So you can look at the first point and see its 5,25 so to find the rate of change you turn the 5 into a 1 by dividing 5/5 which would be 1 but you need to do the same to both sides so you divide 25 by 5 and get 5 so you have the 1 and 5 and you can turn it back to a ratio by putting : instead of the and so it would be 1:5!

sell the PR energy bar for the following prices:
$1.09 $1.29 $1.29 $1.35 $1.39 $1.49 $1.59 $1.79
Sarah claims the average price of the candy bar is $1 37 but Andrew disagreed and said the
average price of the energy bar is actually $1.41. How did Sarah and Andrew come up with these
prices? Based on their calculations, who do you think is correct and why?
My
Answer:
Kindly check explanation
Step-by-step explanation:
Given the data:
$1.09 $1.29 $1.29 $1.35 $1.39 $1.49 $1.59 $1.79
Average value :
Sarah = $1.37
Andrew = $1.41
Obtaining the median:
(n + 1) / 2
n = number of observations = 8
(8 + 1) / 2 = 9 /2 = 4.5th observation
(4th +. 5th observations) / 2
(1.35 + 1.39) / 2 = $1.37
Finding the mean:
($1.09 + $1.29 + $1.29 + $1.35 + $1.39 + $1.49 + $1.59 + $1.79) /8
$11.28 / 8
= $1.41
Hence, the actual. Average value is the mean value of the data.
The median only gives the value at the middle of the distribution and not the average.

Pls Show your work on the slope
Answer:
1) slope = 1/5
x - intercept = (10, 0)
y - intercept = (0,-2)
2) use the method I used for number one to do number 2.
Step-by-step explanation:
slope = rise/run = y2-y1/x2-x1
1)
use any 2 points on a line. Chose one y-value which is y2 and the corresponding x-coordinate is x2. In the other coordinates, the y-value is y1 and the x-value is x1. Let's use points:
(-10, -4)
(-5, -3)
y2 = -3, which means:
y1 = -4
x1 = -10
x2 = -5
plug in the values:
-3-(-4)/-5-(-10)
=1/5
X - intercept is when y = 0. Plug in 0 for y when you see it.
x-0 = 10
x=10
x-intercept = (10,0)
Same for y intercept, except x = 0 this time.
0-5y=10
-5y=10
y=-2
y-intercept = (0,-2)

3. Determine whether these two lines are parallel, perpendicular, or neither. 1 point
8x + y = 7, 4x + 3y = 12 *
parallel,
perpendicular or
neither
Answer:
The two lines are neither
Step-by-step explanation:
Parallel lines have equal slopes and different y-interceptsPerpendicular lines have a product of their slopes = -1The slope of a line whose equation is ax + by = c is m = [tex]\frac{-a}{b}[/tex]∵ The equations of the lines are
8x + y = 7 ⇒ 1st4x + 3y = 12 ⇒ 2nd∵ In the 1st equation a = 8 and b = 1
∴ m1 = [tex]\frac{-8}{1}[/tex] = -8
∴ The slope of the 1st line is -8
∵ In the 2nd equation a = 4 and b = 3
∴ m2 = [tex]\frac{-4}{3}[/tex]
∴ The slope of the 2nd line is [tex]\frac{-4}{3}[/tex]
→ By using the facts above
∵ m1 ≠ m2
∴ The two lines are not parallel
∵ m1 × m2 = -8 × [tex]\frac{-4}{3}[/tex] = [tex]\frac{32}{3}[/tex]
∴ m1 × m2 ≠ -1
∴ The two lines are not perpendicular
∴ The two lines are neither parallel nor perpendicular

The solution for the given inequality is x<4. Therefore, option D is the correct answer.
Given that, 5x-1<2x+11.
What are inequalities?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
Here, inequality 5x-1<2x+11 can be solved as follows
Add 1 on both the sides of inequality, we get
5x<2x+12
Subtract 2x on both the sides of inequality, we get
3x<12
Divide 3 on both the sides of inequality, we get
x<4
The solution for the given inequality is x<4. Therefore, option D is the correct answer.

Eli takes a typing test and types all 180 words in 1 12 hour. He takes the test a second time and types the words in 1 15 hour. Was he faster or slower on the second attempt? Drag and drop the correct word or number into each of the boxes to complete the explanation. Eli typed on his second attempt. He typed words per minute on his first attempt and words per minute on his second attempt.
Step-by-step explanation:
Eli typed faster on his second attempt, 120 words per minute on his first attempt and 150 words per minute on his second attempt.
What is Fraction?A fraction represents a part of a whole.
We need to calculate his typing speed for each attempt.
On his first attempt, Eli typed 180 words in [tex]1\frac{1}{2}[/tex] hours, which is the same as typing 120 words in 1 hour.
Therefore, his typing speed on the first attempt was 120 words per minute.
On his second attempt, Eli typed 180 words in [tex]1\frac{1}{5}[/tex] hour, which is the same as typing 150 words in 1 hour.
Therefore, his typing speed on the second attempt was 150 words per minute.
Comparing the two speeds, we see that Eli was faster on his second attempt, typing 150 words per minute compared to 120 words per minute on his first attempt.
Therefore, Eli typed faster on his second attempt, 120 words per minute on his first attempt and 150 words per minute on his second attempt.
