If an ambulance has an average speed of 0.83 miles per minute and an average response time of 8 minutes, what is the average dis
Mrac [35]

Answer: The average distance the ambulance travels to reach an emergency situation is 6.64 miles.

Step-by-step explanation:

Hi, to answer this question we have to apply the speed formula:

Speed rate = distance / time  

Replacing with the values given:

0.83 miles per minute  = d / 8 minutes

Solving for d (distance)

0.83 mpm x 8 m =d

d =6.64 miles

The average distance the ambulance travels to reach an emergency situation is 6.64 miles.

Feel free to ask for more if needed or if you did not understand something.

one month Miguel rented 5 movies and 3 video games for a total of $27. The next month he ordered 2 movies and 6 video games for
34kurt

Answer:

The price of each movie is $2.25

The price of each video games is $5.41  

Step-by-step explanation:

Given as :

Miguel rented 5 movies and 3 video games for a total cost = $27

Next day Miguel rented 2 movies and 6 video games for a total cost = $36

Let The cost of each movie = $m

And The cost of each video game = $v

Now, According to question

5 m + 3 v = 27            .....1

2 m + 6 v = 36          ...........2

Now, solving the equation

2 × (5 m + 3 v)  - (2 m + 6 v) = 2 × 27 - 36

Or, 10 m + 6 v - 2 m - 6 v = 54 - 36

Or, (10 m - 2 m) + (6 v - 6 v) = 18

Or, 8 m + 0 = 18

∴ m = \dfrac{18}{8} = \dfrac{9}{4}

i.e m = $2.25

So, The price of each movie =  m = $2.25

Again, put the value of m into eq 2

So, 2 × 2.25 + 6 v = 36  

Or, 4.5 + 6 v = 36  

Or, 6 v = 36 - 4.5

Or, 6 v = $32.5

∴ v = \dfrac{32.5}{6}

i.e v = $5.41

So, The price of each video games = v = $5.41

Hence, The price of each movie is $2.25 and

The price of each video games is $5.41  Answer

Solve the system of equations by the substitution method
slava [35]

Answer:

x=0.5

y = 10.5

Step-by-step explanation:

y = 3x + 7

y = 5x + 8

3x + 7 = 5x + 8

3x - 5x=  8 - 7

2x = 1

x= 1/2

x=0.5

y = 5x + 8

y = 5(0.5) + 8

y = 2.5 + 8

y = 10.5
