Answer:

The speed with which Mrs Beck walk is \frac{9}{2}  or 4.5 miles per hour

Step-by-step explanation:

Given:

Distance =  3/4 of a mile

Time  =  1/6 of an hour.

To Find:

Speed = ?

Solution:

We know that

Speed = \frac{distance }{time}

On substituting  the values

Speed = \frac{\frac{3}{4}}{\frac{1}{6}}

Speed = \frac{3}{4} \times \frac{6}{1}

Speed = \frac{18}{4}

Speed = \frac{9}{2}  miles per hour or 4.5 miles per hour

Another way of finding Surface Area is

  1. SA= 2LW+2LH+2HW

L= Length

W= Width

H= Height

the answer, and explained, would be this

2. SA= 2(12)(10)+2(12)(16)+2 (10)(16)

(<em>multiply</em>)

3. SA= 240 + 384 + 320

(<em>add</em>)

<em>The</em><em> </em><em>answer</em><em> </em><em>is</em><em>.</em><em>.</em><em> </em>

<em><u>SA</u></em><em><u>=</u></em><em><u>944ft3</u></em><em><u> </u></em>

The smallest square number which can be divisible by 11 and 5​
Elena L [17]

Answer:

3025

Step-by-step explanation:

let's look at it in this concept.

For a number to be divisible by 11 and 5. it must be a multiple of the LCM of 11 and 5.

LCM of 11 and 5=55

therefore the number is 55x, where x is a positive integer.

it is a said that the number is a perfect square

therefore the square root of 55x must be an integer.

\sqrt{55x}  =  \sqrt{5 \times 11 \times x}

the smallest value of x to make 55x a perfect square is....

x = 11 \times 5 = 55

Therefore the number is.... .

55x = 55(55) = 3025

<em>sweet</em><em> </em><em>right</em>
