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.

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.

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)

The solution for the given inequality is x<4. Therefore, option D is the correct answer.

Given that, 5x-1<2x+11.

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.

Answer:

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.

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.

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.

Answer: x=10, y=7.5

Step-by-step explanation:

For this problem, we are given that BD bisects ABC. That means ABD and DBC are equal to each other. We are also given that ABC is 25. With the given information, we can create two equations.

Equation 1: 2x-y=3y-x

Equation 2: 2x-y+3y-x=25

Now, we can solve for x and y.

2x-y+3y-x=25             [combine like terms]

x+2y=25

Let's simplify Equation 1 by solving for a variable.

2x-y=3y-x                    [add both sides by x]

3x-y=3y                       [add both sides by y]

3x=4y                           [divide both sides by 3]

x=4/3y

Now that we have x, we can plug it into any equation to solve for y.

x+2y=25                      [plug in x=4/3y]

(4/3y)+2y=25              [combine like terms]

10/3y=25                     [multiply both sides by 3/10]

y=15/2

Now we can plug in y=15/2 to solve for x.

x=4/3y                          [plug in y=15/2]

x=4/3(15/2)                  [multiply]

x=10

Now, we know that x=10 and y=7.5.

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).

Answer:

The two lines are neither

Step-by-step explanation:

∵ The equations of the lines are

∵ 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

We must use the given numbers from the table to graph the line.

According to this graph, the slope of the line is [tex]\frac{3}{5}[/tex].

According to this graph, the slope of the line will be; 3/5.

Its slope would be:

[tex]m = \dfrac{y-q}{x-p}[/tex]

The slope of parallel lines is the same. Slopes of perpendicular lines are negatively reciprocals of each other.

Using any two pairs from the table of values given, (-2, 1) and (3, 4):

Where, y = 4, q = 1

x = 3, p = -2

Plug in the value into the slope formula;

[tex]m = \dfrac{y-q}{x-p}\\ m = \dfrac{4-1}{3 + 2}[/tex]

m = 3/5

According to this graph, the slope of the line will be; 3/5.
