This question is worded weirdly, but it means:

8 / (5/2)

= 8 * (2/5)

= 16/5

A survey was taken of twenty dentists about Sparkly toothpaste. Sixteen of the dentists recommended Sparkly toothpaste to their

Bas_tet [7]

Answer: There are 40 dentists who would recommended Sparkly toothpaste to their patients .

Step-by-step explanation:

Since we have given that

Out of 20 dentists, a survey was taken of about Sparkly toothpaste,

Number of dentists recommended Sparkly toothpaste to their patients = 16

Percentage of dentists who recommended Sparkly toothpaste to their patients be

$\frac{16}{20}\times 100=80\%$

Out of 30 dentists, a survey was taken of about Sparkly toothpaste,

Number of dentists recommended Sparkly toothpaste to their patients = 24

Similarly,

Percentage of dentists who recommended Sparkly toothpaste to their patients be

$\frac{24}{30}\times 100=80\%$

Now, we have asked to find the number of dentists recommended Sparkly toothpaste to their patients if survey was taken of 50 dentists.

As we have seen that there is always 80% of total number of dentists surveyed have recommended Sparkly toothpaste to their patients ,

so, According to this pattern , we get that

$\frac{80}{100}\times 50=40$

Hence, there are 40 dentists who would recommended Sparkly toothpaste to their patients .

To take a taxi it costs $3.00 plus an additional $2.00 per mile traveled. You spent exactly $20 on a taxi, which includes the $1

ryzh [129]

This is a basic algebraic word problem. Make x equal the miles you traveled. multiply that by 2 and add the 3 initial dollars, then add the one dollar tip, finally make all this equal to 20. So your equation should look like this:

2x + 3 + 1 = 20

add the 3 and 1:

2x + 4 =20

move the 4 to the right side:

2x = 16

devide both sides by 2:

x = 8

So you traveled 8 miles.
