In this case, you just multiply the expression under the root that gave the greatest integer (as you pull the square root of that number). See how I did: 4 multiplied by 31, which gives 124 then pull out the square root of 4, because 31 can not be, because it is a prime number and root would be an irrational number.

\sqrt{124}=\sqrt{4*31}=\sqrt{31}*\sqrt{4}=2\sqrt{31}=~11.14

Hi, 

<span>Think about your perfect squares: 1, 4, 9, 16, 25, etc. </span>

<span>Therefore, do any of these perfect squares go into 124? Yes, 124 goes into 4, 31 times and therefore we can say: </span>

<span>[ square root of 4 ] [ square root of 31 ] </span>

<span>Now, the square root of 4 is a perfect square which can be simplified down to: </span>

Step-by-step explanation:

lets create a sample space

so

the pirates can be sold for $7 $6 or $9

        p

6       7      9

under the sea can be sold for $6 $7 or $9

                              S

                        6,  7,  9

driving test can be sold for $6 $7 or $9

                            D

                   6, 7, 9

here are all the combinations:

p,6

p,7

p,9

s,6

s,7

s,9

d,6

d,7

d,9

since out of 9 combinations driving test is the only one that is not water related lets look at that. There are only 2 combinations of driving test which are less than or equal to $7, (d,7 and d,6) hence the probability of selling no water games for  less than $7 is 2/9

Terry bought a sweater for$24 before tax he had a coupon for 1/4 off the sales tax rate was 6%. How much did terry pay for the s
Ira Lisetskai [31]

Answer: Terry paid  $18.36 for the sweater.

Step-by-step explanation:

Given: Sales price of sweater = $24

Coupon states \dfrac14 off the sales, i.e. Terry will get \dfrac14\times24=\$6 discount.

Also, tax rate = 6%

Tax will be charged = 6% of Sales price of sweater

=  0.06 x 6

= $0.36

Now , Final amount for Terry = Sales price - discount +tax

= $(24-6+0.36)= $18.36

Hence, Terry paid  $18.36 for the sweater.
