Tom and Jerry leave from the same place in opposite directions. Tom drives 38mph. Jerry drives 50mph. In how many hours are they
devlian [24]

Answer:

Both Tom and Jerry will apart 176 miles in 2 hours .

Step-by-step explanation:

Given as:

Tom and Jerry moves in opposite direction

The speed of Tom = 38 mph

The speed of Jerry = 50 mph

Let The distance cover by Tom = x mile

The  distance cover by Tom = ( 176 - x ) miles

Time taken by both are same = T hour

\textrm(Time) = \dfrac{\textrm(Distance)}{\textrm(Speed)}

Or, Time taken by Tom

T =  \frac{x}{38}     ... 1

∴ x = 38 T  

And Time taken by Jerry

 \textrm(T) = \dfrac{\textrm(Distance)}{\textrm(Speed)}

Or, T =  \frac{176 - x}{50}  

So , put the value of T from 1

\frac{x}{38}  =  \frac{176 - x}{50}  

Or, 50 × x = ( 176 - x ) × 38

So 50 x + 38 x = 6688

Or, 88 x = 6688

∴   x = \frac{6688}{88} = 76 mile

So, From, eq 1

T =  \frac{x}{38}

or, T =  \frac{76}{38}  = 2 hours

Hence both Tom and Jerry will apart 176 miles in 2 hours . Answer

A sequence can be defined by the explicit formula <img src="https://tex.z-dn.net/?f=a_n%3D5-3_n" id="TexFormula1" title="a_n=5-3
astra-53 [7]
<h2>Answer:</h2>

Option: C is the correct answer.

            C.  a_n=a_{n-1}-3\ ;\ a_1=2

<h2>Step-by-step explanation:</h2>

The sequence is given by the explicit formula as:

a_n=5-3n

where a_n is the nth term of the sequence.

Also, the first term of the sequence is: a_1

i.e.

a_1=5-3\times 1\\\\i.e.\\\\a_1=5-3\\\\i.e.\\\\a_1=2

Also,

a_n=5-3n\\\\i.e.\\\\a_n=5-3n+3-3\\\\i.e.\\\\a_n=5-3(n-1)-3\\\\i.e.\\\\a_n=a_{n-1}-3

   Hence, the recursive formula which represents the same sequence is:

                          Option: C

How are the slopes when the lines are parallel in a square ?
Aleks [24]

The slope of parallel lines is equal and the slope of perpendicular lines is a negative multiplicative inverse of each other.

<h3>What is the standard equation of a line?</h3>

The standard equation of a line is given by

y = mx+c

Here m is the slope and c is the y-intercept

The slope can be determined by

m = (y₂ -y₁)/(x₂ -x₁)

A square is a polygon with four sides, the opposite sides are parallel and all the sides are equal, all the angles have an equal measure of 90 degrees.

Two lines are parallel to each other when they are at a fixed distance always and never intersect with each other.

The slope of the lines parallel to each other is equal.

Two lines are said to be perpendicular when they intersect at 90 degrees.

The slope of two perpendicular lines has a product of -1.
