<h3>Answer: Charlotte's speed in meter/second is 2.5m/s.</h3>

Step-by-step explanation:

Given speed of Charlotte in kilometer per hour = 9 km/h

We need to find the Charlotte's speed in meter per second.

We know 1 kilometer = 1000 meter

And 1 hour = 3600 seconds.

Plugging those values of km and hour in given speed in km/h, we get

9\ \frac{km}{h} = 9\times \ \frac{1000m}{3600 seconds}

=\frac{10m}{4s}= 2.5\ m/s.

Therefore,

<h3>Charlotte's speed in meter/second is 2.5m/s.</h3>

Answer:

Speed of Charlotte in a Unit which includes Km and hour =9 \frac{\text{Km}}{\text{hour}}

1 Km=1000 meter

1 hour=60 minutes=3600 seconds

Speed of Charlotte in a Unit which includes meter and second is

                     =\frac{9 \times 1000}{3600}\frac{\text{meter}}{\text{seconds}}\\\\=\frac{90}{36}\frac{\text{meter}}{\text{seconds}}\\\\=\frac{5}{2}\frac{\text{meter}}{\text{seconds}}

(1,5) (2,7)<br> How to find the equation of the line passing through the given points
IceJOKER [234]

Answer:

y = 2x - 3

Step-by-step explanation:

to do this problem, we will use the following formula to find the slope of the line

(y2 - y1) / (x2 - x1)

(1,5) (2,7)

(7 - 5) / (2 - 1)

2 / 1

2 = m

next, we will substitute the slope and one of the points into the slope-intercept form (y = mx + b) and solve for b to find the y-intercept

y = mx + b

7 = (5)(2) + b

7 = 10 + b

-3 = b

finally, we put it all together into one equation

y = 2x - 3

Tyra buys 14 gallons of gas for $35. How could she figure out how much 1 gallon of gas cost
defon

Answer:

The cost of 1 gallon is $2.5

<em></em>

Step-by-step explanation:

Given

Cost of 14 gallons = $35

Required

Determine the cost of 1 gallon

From the given parameters, we have:

14\ gallons = \$35

Divide both sides by 14

\frac{14\ gallons}{14} = \frac{\$35}{14}

1\ gallon = \frac{\$35}{14}

1\ gallon = \$2.5

Hence,

<em>The cost of 1 gallon is $2.5</em>

What is the slope of the line that contains the point (13,-2) and (3,-2)
ra1l [238]

The slope of the line that contains the point (13,-2) and (3,-2) is 0

<em><u>Solution:</u></em>

Given that we have to find the slope of the line

The line contains the point (13,-2) and (3,-2)

<em><u>The slope of line is given as:</u></em>

m = \frac{y_2-y_1}{x_2-x_1}

Where, "m" is the slope of line

Here given points are (13,-2) and (3,-2)

(x_1, y_1) = (13, -2)\\\\(x_2, y_2) = (3, -2)

<em><u>Substituting the values in formula, we get,</u></em>

m = \frac{-2-(-2)}{3-13}\\\\m = \frac{-2+2}{3-13}\\\\m = 0

Thus the slope of line is 0
