Answer:

The question seems to be incomplete, so i will think that this is a linear equation, where we can find the velocity at which she moves, and also her initial position.

A linear relationship can be written as:

y = a*x + b

where a is the slope and b is the y-axis intercept.

For a line that passes through the points (x1, y1) and (x2, y2), the slope can be written as:

a = (y2 - y1)/(x2 - x1).

In this case we have two points:

"After 2 minutes, she was 100 steps from the bottom floor."

this can be represented with the point: (2min, 100 steps)

" After 5 minutes she was 196 steps from the bottom floor"

This can be represented with the point (5min, 196 steps)

With this, we can find the slope of this equation:

a = (196 steps - 100 steps)/(5min - 2min) = 96steps/3min = 32 steps/min

This means that she does 32 steps in one minute.

Then we can write her positon equation as:

y = (32steps/min)*x + b

where x represents the time, and b is her initial position.

If we replace x by 2 min, and y for 100 steps, we get:

100steps = (32steps/min)*2min + b

100 steps = 64 steps + b

100 steps - 64 steps = b = 36 steps.

This means that she started to take the stairs 36 steps from the bottom floor.

Answer:

28 pizzas can be bought

Step-by-step explanation:

you have to find the unit rate of the pizzas.

so 135 divided by 15 which is 9

and then you divide 252 by 9

It is found that 28 pizzas can be bought with 252 dollar.

There is an independent quantity, and a quantity that depends on it (dependent quantity). When independent quantity moves by a unit measurement (single unit increment), the increment in dependent quantity is called the rate of increment of dependent quantity per unit increment in independent quantity.

We have been given amount of money spent on a pizza for club activities varies directly with the number of pizzas bought.

We need to find the unit rate  of the pizzas

Unit rate = Total amount/ Number of pizzas

Unit rate = 35/15

Unit rate = 9

Also,Unit rate = 259/13

Unit rate = 28

Therefore, 28 pizzas can be bought.

Answer:

The profit made is;

b) $285)

Step-by-step explanation:

The given parameters are;

The number of shares bought, n = 50

The price each share is bought, CP = $55

The amount at which each share is sold, SP = $61

The amount the broker received per share, E = $0.30

Therefore, the amount of profit, 'P', is given as follows;

P = n × (SP - CP - E)

By substituting the values for the variables, we have;

P = 50 × (61 - 55 - 0.3) = 285

The amount made as profit, P  = $285.00.

Step-by-step explanation:

If Buddy the Elf stands 6'3" tall and looks up at the Empire State Building (1454' high), what is the angle of elevation if Buddy is 206' from the base of the Empire State Building?

We are to find the angle of elevation which is calculated using the Trigonometric function of Tangent.

tan θ = Opposite/Adjacent

Where:

Opposite = 1454'

Adjacent = 206

tan θ = 1454'/206

Answer: No

Step-by-step explanation:

$12-$4.50= $7.50

$7.50*15= $112.50

The Total cost is $135 She will only be making $112.50 in profits.

Answer:

C = 12 + 15(x - 4)

C = 15x - 48

Step-by-step explanation:

Let the number of hours = t

The total amount Miguel earns =

C

To edit a manuscript, Miguel charges 12 dollars per hour for the first 4 hours and 15 dollars per hour after the first 4 hours.

C = 12 + 15(x - 4)

Expand the t

C = 12 + 15x - 60

C = 15x - 48

Therefore, an expression for the amount, in dollars, Miguel charges if it takes him t hours to edit a manuscript, where t>4 is given as:

C = 15x - 48

Answer:

yes

Step-by-step explanation:

5(8y-8) = 5*8y - 5*8 by distributive property. simplify that, you get 40y-40, which is equal to 40y-40.

Answer:

36° and 54°

Step-by-step explanation:

Let one of the acute angle be "x"

We are told that the other acute angle is 1.5 times the other angle = 1.5x

The right angle = 90°

Find the value of x:

Therefore:

90 + 1.5x + x = 180 (sum of interior angles of triangle)

Add like terms

90 + 2.5x = 180

2.5x = 180 - 90

2.5x = 90

x = 90/2.5

x = 36° (one acute angle)

✔️Second acute angle = 1.5x

Plug in the value of x

= 1.5(36)

= 54°

Answer:

There is no solution to the problem.

Step-by-step explanation:

Key skills: Absolute Value, Division, One Variable Equation

1) We have the equation 3|-3x+9|=-18

2) First, divide by 3 on both sides.

-18/3 is -6

3) This means --> |-3x+9| = -6

4) Absolute Value cannot be negative so there is no solution.

Answer:

1.

The slope is 2

The y-intercept is -10

equation: y = 2x - 10

2.

Slope: 2.5

y-intercept: 1

Equation: y = 2.4x + 1

Step-by-step explanation:

1.

x      y

2      12

4      16

8      24

10     28

from 12 to 16 you add 4

from 2 to 4 you add 2

y/x = 4/2 = 2

The slope is 2

The y-intercept is -10

equation: y = 2x - 10

I got the y-intercept because I went from 12 to 0 which is -12, and then 2 - 12 and it's -10

from 5 to 20 you add 15

y/x = 15/6 = 2.5

Slope: 2.5

y-intercept: 1

Equation: y = 2.4x + 1

I got the y-intercept because I went from 4 to 0 which is -4, and 5 - 4 is 1.

Answer:

Step-by-step explanation:

Answer: You can drive, at most, 2.95 miles per day.

x ≤ 2.95

Step-by-step explanation:

In a single day, you can spend at most $90

Then if C represents the cost of renting the car, then we will have the inequality:

C ≤ $90

Now let's find the equation for C.

We know that we have a fixed cost of $25 plus $22 per mile, then if you drive x miles, the total cost will be $25 plus x times $22, or:

C = $25 + x*$22.

We can now replace that in the inequality:

$25 + x*$22 ≤ $90

Now let's isolate the variable x

x*$22 ≤ $90 - $25

x*$22 ≤ $65

x ≤ $65/$22 = 2.95

x ≤ 2.95

You can drive at most, 2.95 miles per day.

To find other inequalities with the same solution we can start with the solution:

x ≤ 2.95

Now let's multiply both sides by a number (the units of the number can be dollars, in that way we can make a similar problem)

Let's multiply both sides by $10:

x*$10 ≤ 2.95*$10 = $29.5

x*$10 ≤ $29.5

Now let's add the same number in both sides, for example, $5.

x*$10 + $5 ≤ $29.5 + $5 = $34.5

x*$10 + $5 ≤ $34.5

We could write this problem as:

"To rent a cab in your city, you have an initial cost of $5, plus $10 for each mile driven. How many miles could you drive if at most you can spend $34.50?"

You could be more creative with the problem, but this is the way in which you can craft problems of this type when you already know the solution.

Answer: C on edge

Step-by-step explanation:

The rectangular form of the parametric equations x = 4cos(t) – 3 and y = 5sin(t) + 2 is shown in the option third, option third is correct.

A parametric equation in mathematics specifies a set of numbers as functions of one or more independent variables known as parameters.

The missing options are in the attached picture please refer to the picture.

We have two parametric equations:

x = 4cos(t) – 3 and

y = 5sin(t) + 2

From the options plug x and y values in the equation:

[tex]\rm \dfrac{(x+3)^2}{16}+\dfrac{(y-2)^2}{25}=1\\[/tex]

[tex]\rm \dfrac{(4cos(t)-3+3)^2}{16}+\dfrac{(5sin(t)+2-2)^2}{25}=1\\[/tex]

[tex]\rm \dfrac{(4cos(t))^2}{16}+\dfrac{(5sin(t))^2}{25}=1\\[/tex]

cos²t + sin²t = 1  (true)

Thus, the rectangular form of the parametric equations x = 4cos(t) – 3 and y = 5sin(t) + 2 is shown in the option third, option third is correct.

Answer:

52 cars

Step-by-step explanation:

During the first six months of the year the car dealership sold

53 cars

47 cars

62 cars

56 cars

46 cars

48 cars

Therefore the average number of cars sold per month can be calculated as follows

= 53+47+62+56+46+48/6

= 312/6

= 52

Hence an average of 52 cars is sold monthly

Answer:

The pair of equations is consistent

Step-by-step explanation:

A consistent system of equations has at least one solution

An inconsistent system has no solution

In the system of equations ax + by = c and dx + ey = f, if

∵ x - 2y = 0

∴ The coefficient of x ⇒ a = 1

∴ The coefficient of y ⇒ b = -2

∴ The numerical term ⇒ c = 0

∵ 3x + 4y - 20 = 0

→ Add 20 to both sides

∴ 3x + 4y - 20 + 20 = 0 + 20

∴ 3x + 4y = 20

∵ The coefficient of x ⇒ d = 3

∵ The coefficient of y ⇒ e = 4

∵ The numerical term ⇒ f = 20

∵ a ≠ d

∵ b ≠ e

∵ c ≠ f

∵  [tex]\frac{a}{d}[/tex] = [tex]\frac{1}{3}[/tex]

∵  [tex]\frac{b}{e}[/tex] = [tex]\frac{-2}{4}[/tex] = [tex]\frac{-1}{2}[/tex]

∴ [tex]\frac{a}{d}[/tex] ≠ [tex]\frac{b}{e}[/tex]

→ By using rule 3 above

∴ The pair of equations is consistent
