Answer:

Bus B travels faster.

Step-by-step explanation:

Bus A travels according to the equation

y = 125/2 x

This equation is in the form y = mx + b, where m = 125/2, and b = 0.

m is the slope, so the slope is 125/2 which equals 62.5

The slope is the rate of change. Since y is distance in miles, and x is time in hours, the slope is the speed in miles per hour.

The speed of Bus A is 62.5 miles per hour.

Bus B travels according to the graph. We can find the slope by using easy-to-read points on the graph. The slope is the speed in miles per hour.

Look for two points on grid line intersections since they are the easiest ones to read. Let's use point (0, 0) and point (3, 200). Now that we have 2 points, we can find the slope.

slope = \dfrac{y_2 - y_1}{x_2 - x_1}

slope = \dfrac{200 - 0}{3 - 0}

slope = \dfrac{200}{3} = 66.67

The speed of Bus 2 is 66.67 miles per hour.

Answer: Bus B travels faster.

The population at Bishop High School is 2000 students in 2011. Every year the population decreases by 50 students
Artemon [7]

Answer:

  • Let p be the population at t be the number of years since 2011.  Then, p=2000-50t
  • The projected population of the high school in 2015=1800
  • In <u>2019</u> the population be 1600 students

Step-by-step explanation:

Given: The population at Bishop High School students in 2011 =2000

Also,  Every year the population decreases by 50 students which implies the rate of decrease in population is constant.

So, the function is a linear function.

Let p be the population at t be the number of years since 2011.

Then, p=2000-50t

So at t=0, p=2000

In year 2015, t=4, substitute t=4 in the above equation ,we get

p=2000-50(4)\\\Rightarrow\ p=2000-200\\\Rightarrow\ p=1800

Hence, the projected population of the high school in 2015=1800

Now, put p=1600 in the function , we get

1600=2000-50t\\\Rightarrow50t=2000-1600\\\Rightarrow50t=400\\\Rightarrow\ t=\frac{400}{50}\\\Rightarrow\ t=8

Now, 2011+8=2019

Hence, in <u>2019</u> the population be 1600 students

A crew will arrive in one week and begin filming a city for a movie. The mayor is desperate to clean the city streets before fil
Zigmanuir [339]

Answer:

See below in bold.

Step-by-step explanation:

You work in fractions of the city streets done per hour:

1/200 + 1/400 = 1 /x  where x is the number of hours taken by 2 teams.

Multiply through by the LCM 400x:

2x + x = 400

3x = 400

x =  133.33 hours.

As there are 168 hours in a week they will have enough time.
