Answer:

7,000 x 50 = 35* 10^{4}.

Step-by-step explanation:

Given  :  7,000 x 50

To find : What is the product written as the product of a whole number and a power of 10 .

Solution : We have given  7,000 x 50

We can write the  7,000 x 50 = 35, 0000

We can write the 35000  as 35 * 10000.

In term of power 10.

35 * 10000 = 35* 10^{4}.

Here, whole number = 35  and poer of 10 is 4.

Therefore, 7,000 x 50 = 35* 10^{4}.

Anna enjoys dinner at a restaurant in Washington DC where the sales tax on meals is 5%. She leave a 20% tip on the price of her
Maru [420]

Answer:

52.40

Step-by-step explanation:

Discussion

Suppose the meal starts out as x.

She pays 5% of x as a sales tax

So that brings the total up to 100% + 5% = 105%

Before paying, she pays 20% on x as her tip. The tax does not touch the tip.

So that brings the total up to 100% + 5% + 20% = 125% of this is based on x, the cost of the meal.

So 125% of x = 65.50                          change the % to a fraction

125/100 * x = 65.50                             Multiply both sides by 100/125  

125/100 * 100/125x = 100/125 * 65.50

x = 100/125 * 65.50                             Multiply by 100

x = 6550 / 125                                     Divide by 125

Check

Tax = 5% * 52.40 = 5/100 * 52.40 = 2.62

Tip = 20%*52.40 = 20/100 * 52.40=10.48

Meal =                                               52.40

Total                                                  65.50  Just as it should

Multiplying x^2 by 5 stretches the graph vertically by a factor of 5.  Try graphing both x^2 and 5x^2 and see for yourself that this is correct.
