Hi there!

{x}^{2}  \times  {x}^{5}  = x {}^{2 + 5}  =  {x}^{7}

We can also write is out entirely.
{x}^{2}  = x \times x
{x}^{5}  = x \times x \times x \times x \times x
{x}^{2}  \times  {x}^{5}  = \\  (x \times x ) \times (x \times x \times x \times x \times x) =  \\ x \times x \times x \times x \times x \times x \times x =  \\  {x}^{7}

Tom and Jimmy plan to leave at the same time from home and
raketka [301]

To find the distance between the homes of Tom and Jimmy, it is assumed

that the distances from their home to the café are equal.

  • The distance between Tom and Jimmy's home is \underline{1,617.\overline 7 \ meters}<u />

Reasons:

The direction in which Tom and Jimmy walks = Towards each other

The speed at which Tom walks = 52 meters per minute

The speed with which Jimmy walks = 70 meters per minute

The time at which Tom leaves = 4 minutes earlier than Jimmy

The point at which they meet = The café

The rate of their speed = Constant

Required:

The distance between Tom and Jimmy home.

Solution:

Tom and Jimmy had a plan to walk at the same speed and meet up at the café.

We have;

The café is equal distance from Tom and Jimmy's houses.

Which gives the following simultaneous equation.

52 × (4 + t) = The distance of Tom's house from the café

70 × t = The distance of Jimmy's  house from the café

  • 52 × (4 + t) = 70 × t

52 × 4 = 70 × t - 52 × t = 18 × t

\displaystyle t = \frac{52 \times 4}{18}  = \frac{104}{9} = 11.\overline{6}

The time it take Jimmy to reach the café, <em>t</em> = \mathbf{11.\overline6} minutes

The distance between their homes, d = 52 × (4 + t) + 70 × t

∴ d = 52 × (4 + 11.\overline6) + 70 × 11.\overline6 = 1,617.\mathbf{\overline 7}

  • The distance between Tom and Jimmy's home = 1,617.\overline 7 meters

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 .
