An auditorium has rows of seat 8 seats in each row. Kayla knows there are at least 70 seats but fewer than 150 seats in the audi
yKpoI14uk [10]

The possible number of rows in the auditorium can be 9, 10, 11, 12, 13, 14, 15, 16, 17, or 18

<h3><em><u>Solution:</u></em></h3>

Given that auditorium has rows of seat 8 seats in each row

1 row = 8 seats

Kayla knows there are at least 70 seats but fewer than 150 seats in the auditorium

Let the number of seats be x

Therefore,

70 < x < 150

We know that 1 row has 8 seats

First number after 70 which is divisible by 8 is 72

9 \times 8 = 72

Since 8 is the number of seats in each row so, 9 denotes the number of rows

Last number just before 150 which is divisible by 8

18 \times 8 = 144

Since 8 is the number of seats in each row so, 18 denotes the number of rows

So, the actual number of rows can be between 9 and 18

We can say that possible number of rows can be 9, 10, 11, 12, 13, 14, 15, 16, 17, or 18

Answer:

3\sqrt{10}

Step-by-step explanation:

Assuming you mean \sqrt{90}

Using the rule of radicals

\sqrt{a} × \sqrt{b} ⇔ \sqrt{ab} , then

\sqrt{90}

= \sqrt{9(10)}

= \sqrt{9 × \sqrt{10}

= 3\sqrt{10}
