What is (-8)(-x)(-x)

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 .

Please help with this arc equation.

boyakko [2]

Answer:

Part 1) $arc\ AB=49^o$

Part 2) $arc\ ABC=204^o$

Part 3) $arc\ BAC=156^o$

Part 4) $arc\ ACB=311^o$

Step-by-step explanation:

Part 1) Find the measure of arc AB

we know that

$arc\ AB=m\angle AOB$ ----> by central angle

we have

$m\angle AOB=49^o$

therefore

$arc\ AB=49^o$

Part 2) Find the measure of arc ABC

we know that

The central angle of complete circle is equal to 360 degrees

so

$arc\ ABC=360^o-107^o-49^o=204^o$

Part 3) Find the measure of arc BAC

we know that

$arc\ BAC=arc\ BA+arc\ AC$ ----> by angle addition postulate

we have

$arc\ BA=49^o$ ---> by central angle

$arc\ AC=107^o$ ---> by central angle

so

$arc\ BAC=49^o+107^o=156^o$

Part 4) Find the measure of arc ACB

we know that

The central angle of complete circle is equal to 360 degrees

so

$arc\ ACB=360^o-arc\ AB$

substitute

$arc\ ACB=360^o-49^o=311^o$
