QUESTION POSTED AT 05/12/2019 - 01:38 PM

The process of writing repeating decimals or repeating pattern of digits by using a bar is called Bar Notation. Bar notation can be put with single or multi-digit repeating numbers or repeating patterns of decimals. For a single-digit repeating decimal, the repeating number is written once and a bar is put over it.

**Answer:**

Option 3 - ** **

**Step-by-step explanation:**

**Given : **Number -

**To find :** Re-write the number into standard notation?

**Solution : **

**Standard notation **in the expansion of scientific notation.

**Scientific notation**

means 10 with 6 zeros i.e. 1000000

**So,**

**Removing decimal,**

**Therefore, **

**So, Option 3 is correct.**

**Answer:**

** .**

**Step-by-step explanation:**

Given : 105,000

To find : Rewrite 105,000 in scientific notation.

Solution : We have given 105,000 .

**Steps to write in scientific notation :
**

**
Step 1 : If a number has n digit we move decimal point ( n-1) place to left and to balance , multiply by .
**

We can see there are** n = 6** in 105,000

So, we move decimal point 5 place to the left .

Then .

**Therefore, .**

For a polygon inscribed in a circle, the circle passes through all of the vertices of the polygon. Using this idea, a polyhedron (a 3-D polygon) inscribed in a sphere can be described in a similar way. The sphere also touches all of the vertices of the polyhedron, except this is done in 3 dimensions, not limited to just 2 dimension.

Given:

weight of mixture : 1792 ounces

output of mixture : 560 bars of soap

to get the weight per unit, we simply divide by total weight by the total number of output.

1792 oz / 560 bars = 3.2 ounces per bar.

QUESTION POSTED AT 18/01/2020 - 01:07 AM

Since we are already given the amount of jumps from the first trial, and how much it should be increased by on each succeeding trial, we can already solve for the amount of jumps from the first through tenth trials. Starting from 5 and adding 3 each time, we get: 5 8 (11) 14 17 20 23 26 29 32, with 11 being the third trial.

Having been provided 2 different sigma notations, which I assume are choices to the question, we can substitute the initial value to see if it does match the result of the 3rd trial which we obtained by manual adding.

Let us try it below:

Sigma notation 1:

10

Σ (2i + 3)

i = 3

@ i = 3

2(3) + 3

12

The first sigma notation does not have the same result, so we move on to the next.

10

Σ (3i + 2)

i = 3

When i = 3; 3(3) + 2 = 11. (OK)

Since the 3rd trial is a match, we test it with the other values for the 4th through 10th trials.

When i = 4; 3(4) + 2 = 14. (OK)

When i = 5; 3(5) + 2 = 17. (OK)

When i = 6; 3(6) + 2 = 20. (OK)

When i = 7; 3(7) + 2 = 23. (OK)

When i = 8; 3(8) + 2 = 26. (OK)

When i = 9; 3(9) + 2 = 29. (OK)

When i = 10; 3(10) + 2 = 32. (OK)

Adding the results from her 3rd through 10th trials: 11 + 14 + 17 + 20 + 23 + 26 + 29 + 32 = 172.

Therefore, the total jumps she had made from her third to tenth trips is 172.

**Answer:**

b. 3.532×10^-4

**Step-by-step explanation:**

If you have: 0,0003532

you have to put the comma 4 positions to the right in order to get the number "3,532"

Then you can to express the number in scientific notation like 3.532×10^-4

which means that to return to the original number you must run the comma 4 positions to the left.

QUESTION POSTED AT 17/01/2020 - 02:10 AM

**Answer:**

The answer is:

**Step-by-step explanation:**

In order to determine the answer, we have to know about **scientific notation.**

In general the scientific notation is:

where:

a= **rational number **such that its absolute value has to **satisfy**:

b= the **power of 10** required so that the scientific notation is mathematically equivalent to the original number.

We have to follow the **next steps **to determine the **scientific notation **of any number:

**Move**the decimal point in your number until there is only one non-zero digit to the left of the decimal point. The resulting decimal number is "a".**Count**how many places you moved the decimal point. This number is "b".- If you moved the decimal to the
**left**, "b" is**positive**. If you moved the decimal to the**right**, "b" is**negative**. If you**did not need**to move the decimal, "b" = 0. **Remove**trailing 0's only if they were originally to the left of the decimal point.

Finally, the number 0.000000028 written in scientific notation is:
