Two consecutive whole number that lies between the square root of 38
Semenov [28]
√38

Let's name all the squares.
1² = 1 x 1 = 1
2² = 2 x 2 = 4
3² = 3 x 3 = 9
4² = 4 x 4 = 16
5² = 5 x 5 = 25
6² = 6 x 6 = 36
7² = 7 x 7 = 49
8² = 8 x 8 = 64

Okay that's far enough. Now we look for which numbers 38 is in between.
That would be 36 and 49.
But it's asking for where the square root of 38 is, so √36 and √49 ⇒ 6 and 7.

Find the slope of the graph and the unit rate
Lilit [14]

Answer:

<u>For the 1st graph</u>

Slope     = \frac{6}{10}

Unit rate =0.6 mi/h

               

<u>For the 2nd graph</u>

Slope     = \frac{9}{4}

Unit rate =2.25 mi/h=


Step-by-step explanation:

<u>For the 1st graph</u>

Slope is given as \frac{Rise}{Run}

Rise = (6-0) = 6

Run = (10-0) = 10

Therefore,

Slope     = \frac{6}{10}

Unit rate = \frac{6}{10}

               =0.6 mi/h

<u>For the 2nd graph</u>

Rise = (9-0) = 6

Run = (4-0) = 10

Therefore,

Slope     = \frac{9}{4}

Unit rate = \frac{9}{4}

               =2.25 mi/h
