The approximate value of 5.5 million x 1.9 thousand is(scientific notation)

1 answer:

5 0

The answer is: " <span>1.045 * 10¹⁰ " .</span>
_____________________________________
Explanation:
______________________________________
"5.5 million = 5,500,000 = 5.5 * 10 ⁶ " ;
______________________________________
"1.9 thousand = 1,900 = 1.9 * 10³ " ;
______________________________________
So; "<span>5.5 million * 1.9 thousand" ;
_________________________________________
= (</span>5.5 * 10 ⁶) * (1.9 * 10³) = 5.5 * 10⁶ * 1.9 * 10³ ;

= 5.5 * 1.9 * 10⁶ * 10³ ;
___________________________________________
Note the following properties of exponents:
____________________________________________
xᵃ * xᵇ = x⁽ᵃ⁺ᵇ⁾ ;
____________________________________________

As such, " 10⁶ * 10³ = 10⁽ ⁶ ⁺ ³⁾ = 10⁹ " ;
_____________________________________
So; rewrite:
______________________________________
5.5 * 1.9 * 10⁶ * 10³ ;
_______________________________________
= 5.5 * 1.9 * 10⁹ ;
__________________________________
5.5 * 1.9 = 10.45 ;
__________________________________
Rewrite as: " 10.45 * 10⁹ " ;

In scientific notation, we need to rewrite as an single digit integer, followed by a decimal and other values (if applicable); following by * 10 raised to the appropriately adjusted exponential power.
_________________________________________________
As such, we write the value as:
________________________________________________
" 1.045 * 10¹⁰ " .

Solve the system of equations using elimination. How many solutions does the system have?

Morgarella [4.7K]

Answer:

I hope it helps u

Step-by-step explanation:

Let's solve your system by elimination.

15j+12k=18;5j+4k=6

Multiply the second equation by -3, then add the equations together.

(15j+12k=18)

−3(5j+4k=6)

Becomes:

15j+12k=18

−15j−12k=−18

Add these equations to eliminate j:

0=0

Answer:

Infinitely many solutions

Note: Please Brain-list it ok dear!

The girls in Lana’s troop set a goal to sell 1,000 boxes of cookies this year. There are 13 girls in the troop. At least how man

motikmotik

Answer:

$77$

Step-by-step explanation:

The troop wants to sell a minimum of 1,000 boxes, so we're looking for the smallest number of boxes they can sell and still meet the goal. Since there are 13 girls in the troop, take the ceiling (round up to the nearest whole number) of 1,000 divided by 13:

$\left\lceil \frac{1,000}{13}\right\rceil=\boxed{77}$

What is permutation and combination?

A set of elements can be divided into subsets in two different ways: combination and permutation.

The components of the subset may be arranged in any order when combined. The components of the subset are listed in a permutation in a certain order.

If the word has 5 different letters then it is just 26-choose-5 or (26/5).

If the word has 4 different letters then it is just 26-choose-4 or (26/4)

have 4 options to choose which letter to duplicate twice.

This gives = 4*(26/4)

If the word has 3 different letters then it is just 26-choose-3 or (26/3).

you duplicate one of the three letters 3 times - 3 options for that, or you choose 2 letters and duplicate each one twice - again 3 options. In total this gives = 6*(26/3).

If the word has 2 different letters then it is just 26-choose-2 or (26/2).

The sets of 2 different letters and duplicate either one of the letters 4 times - 2 options; or duplicate one letter 2 times, and the other 3 times - again 2 options. In total this is = 4*(26/2).

The word has just 1 distinct letter you have = (26/1).

we get :

N = (26/5)+ 4*(26/4) + 6*(26/3) + 4*(26/2) + (26/1)

= 142506
