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}

A bottle of water costs $1.50. Explain how you would make a graph of four ordered pairs to model the total cost of the water in
Vanyuwa [196]
Total cost = 1.50 per bottle
y = 1.50x
If x = 1, y = $ 1.50 (1,1.5)
If x = 2, y = $ 3.00 (2,3)
If x = 3, y = $ 4.50 (3, 4.5)
If x = 4, y = $ 6.00 (4, 6)
There are your 4 sets of ordered pairs to graph.
You could continue with more x-values to get more ordered pairs.

Dina and Masha started out on a 12 mi bike path at the same time. When Dina reached the end of the 12 mi, Masha still had 3 mi l
Anna35 [415]

Answer:

6 mph

Step-by-step explanation:

Use formula

D=r\cdot t,

where

D = distance

r = rate

t = time

In your case,

D = 12 mi

<u>Dina:</u>

D = 12 mi

r = 8 mph

t = ?

So,

12=8t\\ \\t=\dfrac{12}{8}=\dfrac{3}{2}=1.5\ hours

<u>Masha:</u>

D = 12 - 3 = 8 mi

r = ?

t = 1.5 hours

Then

9=1.5r\\ \\r=\dfrac{9}{1.5}=\dfrac{90}{15}=6\ mph
