2) last zero not count for number (2050 ) significant figure = 3

AleksAgata [21]

Answer:

$30.00

Step-by-step explanation:

The original price of the sweater is $75.00.  The new sale price is the original price of  100% less  60% of the original price.  That means the sales price is 40% of the original price.

You can do this 2 ways:

1.  $75 x 60% or .60 = $45

  $75-45 = $30

or

2.  $75 x 40% or .40 = $30

What's the question? The estimated product of two numbers that are not multiples of 10 is 2800.
Neporo4naja [7]

Seems to me like the question is:  What are the two numbers ?

They have to multiply to  2,800 . 
It's fairly easy to find two numbers that do that,  BUT ...
they're not supposed to be multiples of 10 .

1 x 2,800 = 2,800 . . . . . No good.  2,800 is a multiple of 10 .

2 x 1,400 = 2,800 . . . . . No good.  1,400 is a multiple of 10 .

4 x 700 = 2,800 . . . . . No good.  700 is a multiple of 10 .

5 x 560 = 2,800 . . . . . No good.  560 is a multiple of 10 .

7 x 400 = 2,800 . . . . . No good.  400 is a multiple of 10 .

8 x 350 = 2,800 . . . . . No good.  350 is a multiple of 10 .

10 x 280 = 2,800 . . . . . No good.  280 is a multiple of 10 .

14 x 200 = 2,800 . . . . . No good.  200 is a multiple of 10 .

16 x 175 = 2,800 . . . . . Finally !  Neither one is a multiple of 10 .

You are having a family meeting during the a epidemic. You want to follow the guidelines and know everyone has to stay 6 feet ap
Lady_Fox [76]

Answer:

a.

Total No. of People = 8 people

b.

Total No. of People = 6 people

Hence, we can not fit the same amount of people in both rooms.

Step-by-step explanation:

a.

Here, the dimensions of the room are 12 ft by 24 ft. So, in order to maintain the 6 ft distance, we can allow following number of people in it.

No. of people along 24 ft dimension = 24 ft/6 ft

No. of people along 24 ft dimension = 4

No. of rows along 12 ft dimension = 12 ft/6 ft

No. of rows along 12 ft dimension = 2

So, the total no. of people is given as:

Total No. of People = (People along 24 ft)(Rows along 12 ft)

Total No. of People = (4)(2)

<u>Total No. of People = 8 people</u>

<u></u>

b.

Here, the dimensions of the room are 16 ft by 18 ft. So, in order to maintain the 6 ft distance, we can allow following number of people in it.

No. of people along 16 ft dimension = 16 ft/6 ft

No. of people along 16 ft dimension = 2.67

In order to maintain minimum 6 ft distance the no. of people is rounded down to 2.

No. of people along 16 ft dimension = 2

No. of rows along 18 ft dimension = 18 ft/6 ft

No. of rows along 18 ft dimension = 3

So, the total no. of people is given as:

Total No. of People = (People along 24 ft)(Rows along 12 ft)

Total No. of People = (2)(3)

<u>Total No. of People = 6 people</u>

<u>Hence, we can not fit the same amount of people in both rooms.</u>

<u></u>
