<h2>Hello!</h2>

The answer is:

The equation that represents the relationship between the time (t) and the total distance (d) is:

Distance=95\frac{miles}{hour}*t

<h2>Why?</h2>

From the given table, we can deduce that the traveled distance increases with a rate of 95 miles each hour. So, using that information, we can write an equation to represent the relationship between time (t), and the total distance (d).

Writing the equation, we have:

We need to consider that the speed is equal to:

v=95\frac{mile}{hour}

Then, the equation will be:

x=x_{o} +v*t\\x-x_{o}=v*t\\Distance=v*t

Now, substituting the speed into the equation, we have:

Distance=95\frac{miles}{hour}*t

Hence, the equation that represents the relationship between the time (t) and the total distance (d) is:

Distance=95\frac{miles}{hour}*t

Have a nice day!

In ∆RST, which side is included between ∠R and ∠S?
Lera25 [3.4K]
Hi there!

Since triangle RST is stated with the sides in order (R is connected to S, which is connected to T, which is then connected to R), the side between R and S is T. 

Hope this helps!

How to do this question plz ​
enyata [817]

Answer:

  x = 10

Step-by-step explanation:

Use the Pythagorean theorem. The sum of the square of the sides is the square of the hypotenuse.

  x² +(√200)² = (√300)²

  x² = 300 -200

  x = √100 = 10

The length of the unknown side is 10 units.

Find the area of the square
butalik [34]

Answer:

13 units^2

Step-by-step explanation:

one side of the square =

AD^{2} = 2^{2} +3^{2}

AD^{2} =13

AD = \sqrt{13}

So area of square = Length * Length

= \sqrt{13}*

= 13

Given the system of equations, what is the solution?
fredd [130]

The solution for the given equations  x + 3y = 5 and x - 3y = -1 are x=2 and y=1.

Step-by-step explanation:

The given is,

           x+3y=5......................................(1)

           x-3y=-1....................................(2)

Step:1

         By elimination method,

        Subtracting Equations (1) and (2),

                     x+3y=5

                     x-3y=-1

             ( - )

           ( x-x ) + ( 3y+3y ) = ( 5 +1 )

                                       6y = 6

                                         y = 1

Step:2

        Substitute the value of y in equation (1),

                             x+3y=5

                       x + ( 3 × 1 ) = 5

                                      x = 5-3

                                      x = 2

Step:3

        Check for Solution,

        Substitute the values of x and y in Eqn (1),

                                  x+3y=5

                           2 + ( 3 × 1 ) = 5

                                         5 = 5

Result:

       The solution for the given equations  x + 3y = 5 and x - 3y = -1 are x=2 and y=1, by elimination method.
