It takes 30.07 minutes for Charmaine to run  4 miles

Step-by-step explanation:

Given:

Distance covered by  Charmaine = 6 miles

Time taken by Charmaine to run 6 miles = 45 minutes

To find:

Time taken by Charmaine to run 4 miles=?

Solution:

We know that ,   Speed=\frac{distance}{time}...................(1)

Substituting the values given in the question,

speed=\frac{6}{45}

speed=0.133 miles/minute

Re writing the equation (1), we have,

Time=\frac{Distance}{Speed}

Now substituting the spees and distance values, we get

Time taken by Charmaine to run 4 miles= \frac{4}{0.133}

Time taken by Charmaine to run 4 miles=  30.07 minutes.

Yuki888 [10]

Answer:

The actual distance between the two rivers is <u>232.5 kilometers</u>.

Step-by-step explanation:

GIven:

The scale on a map is 2 centimeters= 50 kilometres.Two rivers on a map are located 9.3 centimeters apart.

Now, to find the actual distance between the two rivers.

Let the actual distance between the two rivers is x.

The two rivers on the map is located apart of 9.3 centimeters.

According to the scale on the map is 2 centimeters = 50 kilometers.

<em>So, 2 centimeters is equivalent to 50 kilometers.</em>

<em>Thus, 9.3 centimeters is equivalent to </em>x.<em />

Now, to solve by using cross multiplication method:

\frac{2}{50} =\frac{9.3}{x}

<em>By cross multiplying we get:</em>

<em />2x=465<em />

<em>Dividing both sides by 2 we get:</em>

x=232.5\ kilometers.

Therefore, the actual distance between the two rivers is 232.5 kilometers.

The height of water shooting my fountain is modeled by the function f(x)= -4x^2 +24x -29 where x the distance from the spout in
Doss [256]

By the use of the completing the square method, the maximum height is 3 ±√29/4 + 9 m.

<h3>What is the maximum height of the water?</h3>

The maximum height has been modeled by the use of the equation f(x)= -4x^2 +24x -29. Now we know that f(x)= h so we can write;

h = -4x^2 +24x -29

Now we have;

0 = -4x^2 +24x -29

-4x^2 +24x -29= 0

x^2 - 6x = -29/4

(x - 3)^2 = -29/4 + 3^2

(x - 3)^2 =  -29/4 + 9

x = 3 ±√29/4 + 9 m
