Answer:

Time for a round trip = 12.5 hours

Step-by-step explanation:

Mother's house = 250 miles

Total distance for the round trip = 250 + 250 = 500 miles

Given speed = 40 mph

<em><u>Find time .</u></em>

<em><u></u></em>Speed = \frac{distance }{Time }\\\\Time = \frac{distance }{speed } = \frac{500}{40} \\\\Time  = 12.5 \ hours<em><u></u></em>

Answer:

3\frac{1}{4}

Step-by-step explanation:

we have to  divide the given distance by 3.

Then we will be able to find the distance between markers.

Given distance is

9\frac{3}{4} \\=\frac{36+3}{4}\\ =\frac{39}{4}

Since, there are three markers,

So, we have to divide this distance by  3

So, the distance between markers is-

\frac{\frac{39}{4}} {3} \\=\frac{39}{4} * \frac{1}{3} \\=\frac{13}{4}


So, the distance between marker is

\frac{13}{4}

Now, we have to convert this into mixed number.

Then, the distance is-

\frac{13}{4}\\ =3\frac{1}{4}

Evaluate the expression if m = − 4 , n = 1 , p = 2 , q = − 6 , r = 5 , and t = − 2 | 16 + 4 ( 3 q + p )
Arisa [49]

The evaluation of the expression, if m = − 4 , n = 1 , p = 2 , q = − 6 , r = 5 , and t = − 2 | 16 + 4 ( 3 q + p ) is 46.

<h3>How can the expression be simplified?</h3>

the given expression is  t = − 2 | 16 + 4 ( 3 q + p )

Then since we are given  m = − 4 , n = 1 , p = 2 , q = − 6 , r = 5

Then, we can substitute all the given values of the terms into the given expression as :

t = − 2 | 16 + 4 ( 3 q + p )

t= -2 I 16+4(-18+2)

t= -2 I 16+4(-16)

t= -2 I 16 -64

t= -2 I -48

t =46

What is the solution set of the quadratic inequality 4(x 2)2&lt;0
nekit [7.7K]
If you would like to solve the inequality 4 * (x + 2)^2 < 0, you can do this using the following steps:

4 * (x + 2)^2 < 0
4 * (x^2 + 4x + 4) < 0     /4
x^2 + 4x + 4 < 0
no solutions

The correct result would be: There are no solutions.
