What is a number system?

The number system is a way to represent or express numbers.

A decimal number is a very common number that we use frequently.

Since the decimal number system employs ten digits from 0 to 9, it has a base of 10.

Any of the multiple sets of symbols and the guidelines for utilizing them to represent numbers are included in the Number System.

Given,

Diameter of structure =  9 × 10⁻⁹ meter

Multiply and divide by 10⁹

Diameter of structure =  9 × 10⁻⁹ ×  10⁹/ 10⁹

By the law of indices

Diameter of structure = 9/10⁹

Diameter of structure = 0.000000009

Hence "The correct answer to the following question will be 0.000000009".

Answers

Answer: x= 2

Step-by-step explanation:

hope this helped :)

Answer:

x=7

Step-by-step explanation:

well there's a simple way to do this, you out each side by side like so and solve:

3x+6=-15+6x

then you move like terms to the other side (like terms have the same variables). So we'll add 15 to both sides to balance the equation out because you cant remove a number from one side without affecting the other so:

3x+21=6x

then because we don't want an equation equal to 0 we move 3x to the other side by substracting 3x from both sides:

21=3x

now we divide by 3 both sides and because 21 divided by 3 is 7:

x=7

hope it helped (^u^)

Ferdie was having a big party and he was excited. He had been practicing his opening lines all week and as soon as he he got to the part, 20 girls at the party left. There now remained 2 boys for each girl. A lot of the other boys thought the party was pathetic, so 20 of the boys also left. There were now 3 times as many girls as boys. How many boys and girls were at the party when Ferdie got there?

Answers

Answer: Boys = 24

Girls = 32

Step-by-step explanation:

Let the original number of boys = b

Let the original number of girls = g

The following can be further gotten from the question:

When 20 girls left, the equation can be written as:

b = 2(g - 20)

b = 2g - 40 ........ equation i

When 20 boys left, the equation can be written as:

(g-20) = 3(b-20) ......... equation ii

Substitute the value of b into equation ii and solve.

(g-20) = 3(b-20)

g - 20 = 3(2g - 40 - 20)

g - 20 = 3(2g - 60)

g - 20 = 6g - 180

6g - g = 180 - 20

5g = 160

g = 160/5

g = 32

Therefore, the original number of girls = 32.

The original number of boys will be:

b = 2g - 40

b = 2(32) - 40

= 64 - 40

= 24

Answers

x= 1/2

Step-by-step explanation:

start by adding 6/3 to both sides. the negative 6/3 on the left side will disappear, and the right side will equal one. (6/3 + 3/6= 9/9 = 1).

Youll end up with:

3x=x+1

now, subtract x from both sides to get:

2x=1

Divide both sides by two to get

x=1/2

if the average of 2 and p is equal to the average of 1,6, and p, what is the value of p

Answers

Answer:

p = 8

Step-by-step explanation:

[tex]\frac{2+p}{2}=\frac{1+6+p}{3}\\\\\frac{2+p}{2}=\frac{7+p}{3}\\\\[/tex]

Cross multiply

 (2+p) * 3 = (7 + p) * 2          {Use distributive rule}

2*3 + p*3 = 7*2 + p *2

    6+ 3p   = 14 + 2p          {subtract 2p form both sides}

6 + 3p - 2p= 14

      6 + p  = 14                {Subtract 6 form both sides}

              p = 14 - 6

              p = 8
