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}

B- They are always congruent. Congruent means in agreement or harmony. But in this case, identical in form. Parallelograms are parallel on both sides, which makes them have congruent sides. 
P.S.- This is elementary level, no offense.

What is the center and radius of the circle that has the equation (x + 7)^2 + (y - 4)^2 ? Explain.
lesya [120]

Answer:

(-7, 4) and 7

Step-by-step explanation:

The standard equation of a circle is expressed as (x - a)^2  + (y - b )^2 = r^2

Where the center is the point (a, b) and the radius is r

Note: simply inserting the variables and playing around with your signs gives you the value for (a and b)

The square root of the radius gives you the value for r
