Write the following numbers in expanded form and exponential form a. 4081673 b.561827 c.892 d.3848 e. 777320916

We need to write in expanded form and exponential form. So

1. 4081673 = 4000000 + 0 + 80000 + 1000 + 600 + 70 + 3

= 4 x 10^6 + 0 + 8 x 10^4 + 1 x 10^3 + 6 x 10^2 + 7 x 10^1 + 3 x 10^0

2. 561872 = 500000 + 60000 + 1000 + 800 + 70 + 2

= 5 x 10^5 + 6 x 10^4 + 1 x 10^3 + 8 x 10^2 + 7 x 10^1 + 2 x 10^0

3. 892 = 800 + 90 + 2

= 8 x 10^2 + 9 x 10^1 + 2 x 10^0

4. 3848 = 3000 + 800 + 40 + 8

= 3 x 10^3 + 8 x 10^2 + 4 x 10^1 + 8 x 10^0

5. 777320916 = 700000000 + 70000000 + 7000000 + 300000 + 20000 + 0 + 900 + 10 + 6

= 7 x 10^8 + 7 x 10^7 + 7 x 10^6 + 3 x 10^5 + 2 x 10^4 + 0 + 9 x 10^2 + 1 x 10^1 + 6 x 10^0

The mean of the data set(9,5,y,2,x)is twice the data set (8,x, 4,1,3).What is (y-x)

pantera1 [17]

Answer:

y - x = 16

Step-by-step explanation:

Explanation:-

Step(i):-

Given data set A is 9,5,y,2,x

Mean of the Data set A

= $\frac{9 + 5 + y + 2 +x}{5}$

= $\frac{16 +x+y}{5}$

Given data set B is 8, x, 4, 1, 3

Mean of the Data set B

= $\frac{8+ x+4+1+3}{5}$

Step(ii):-

Mean of the Data set A = 2 X Mean of the Data set B

$\frac{16 +x+y}{5} = 2 X \frac{16+x}{5}$

On simplification , we get

16 +x + y = 2( 16 +x)

16 + x + y = 32 + 2 x

16 + x + y - 32 - 2 x = 0

y - x -16 =0

y - x = 16

Triangles LMN and NWR are right triangles. What is

Sever21 [200]

Answer:

NW = 15.6 cm

Step-by-step explanation:

If ΔLMN ~ ΔNWR then:

$\sf LN : LM = RN : RW$

$\implies \sf \dfrac{LN}{LM}=\dfrac{RN}{RW}$

$\implies \sf \dfrac{10}{24}=\dfrac{6}{RW}$

$\implies \sf 10RW=6 \cdot 24$

$\implies \sf RW = 14.4\:cm$

Find NW by using Pythagoras' Theorem:

$a^2+b^2=c^2$

(where a and b are the legs, and c is the hypotenuse, of a right triangle)

Given:

a = RN = 6 cm
b = RW = 14.4 cm
c = NW

Substituting the given values into the formula and solving for NW:

$\implies \sf 6^2+14.4^2=NW^2$

$\implies \sf NW^2=243.36$

$\implies \sf NW=\sqrt{243.36}$

$\implies \sf NW=15.6\:cm$

HELP FIND THE AREA PLS BRAINLY WILL BE GIVEN

irakobra [83]

Answer:

the area is 60 square units

Step-by-step explanation:

Area = (base x height) / 2

from class 1 to 2 is 10 units

from class 2 to 3 is 12 units

10 x 12 / 2

10 x 12 = 120

120 / 2 = 60

PLZ HELP FIRST RIGHT GETS BRAINLEST

konstantin123 [22]

Answer:

$\frac{1}{8}$ or $\frac{9}{78}$

(see explanation)

Step-by-step explanation:

This problem is asking about compound probability, what is the probability of this even happening three times in a row.

Since there are 20 boy's names and 20 girl's names in the hat, one can say that half of the names in the hat. Assume that after drawing it from the hat, the name is put back into the hat. Therefore, on each night, there is a half-chance of the event happening. To find the probability of the event, one must multiply ( $\frac{1}{2}$ ) by itself (3) times,

$(\frac{1}{2})(\frac{1}{2})(\frac{1}{2})\\=\frac{1}{8}$

In this case, assume that after each drawing the name is not replaced into the hat. This means that after every draw, one must subtract (1) from both the numerator and denominator of the fraction when the fraction is in the un-simplified form.

$(\frac{1}{2})(\frac{19}{39})(\frac{18}{38})$

Simplify,

$(\frac{1}{2})(\frac{19}{39})(\frac{9}{19})$

$\frac{9}{78}$
