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".

Consider the equation:
4(2 + px) = 12x
For what value of p does the equation have no solution?
A 1
B. 3
C 12
D. 48
Answer:
p = 3
Step-by-step explanation:
Given
4(2 + px) = 12x
If the coefficient of the x- term is the same on both sides of the equation, it will have no solution.
Distributing gives
8 + 4px = 12x ( equate the coefficients of the x- term )
4p = 12 ( divide both sides by 4 )
p = 3
The value of p when the equation has no solution will be 3. Then the correct option is B.
What is a linear equation?A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
The linear equation is given below.
4(2 + px) = 12x
8 + 4px = 12x
If the coefficient of the x-term is the same on both sides of the equation, it will have no solution.
4p = 12
p = 3
The value of p when the equation has no solution will be 3. Then the correct option is B.

Step-by-step explanation:
3 quarts of apples juice for $3.59 OR 1 gallon (4 quarts) of apple juice for $3.99
Answer:
1 gallon is the better deal
Step-by-step explanation:
If you divide 3.99/4 you get 0.9975. Therefore, a quart of apple juice costs 0.9975. If you divide 3.59/3, you get 1.19 which is more expensive than 0.9975. The answer is 1 gallon of apple juice for 3.99 is the better deal.

A tree is casting a shadow of 28 ft. At the same time, a 7ft statue was casting a shadow of 2ft. How tall is the tree? Remember, I don't want the answer just an explanation
(●'◡'●)
Answer:
Step-by-step explanation:
You have to find ratio for feet for a shadow.
In your case, a 7ft statue was casting a shadow of 2ft. You divide 7/2 and it results in 3.5 feet in real life vs. 1 foot shadow. You do the same for the tree. Since it is 3.5 feet:1 foot statue, you have to multiply 3.5 by 28 to get the full height of the tree. (In this example the shadow is smaller than the tree that's why you multiply).

The equation 4 (x - 2) = 100 is a true equation for a particular value of x. Explain why 2 (x - 2) = 50 is also true for the same value of x.
Answer:
Step-by-step explanation:
i. 4 (x - 2) = 100
x-2= 100/4
x-2=25
x=25+2
x=27
ii. 2 (x - 2) = 50
x-2= 50/2
x-2=25
x=25+2
x=27
The equation 4 (x - 2) = 100 is a true equation for x when x = 27
4 (x - 2) = 100
4x - 8 = 100
Collect like terms
4x = 100 - 8
4x = 92
Divide both side by 4
4x/4 = 92/4
x= 27
Also the equation 4 (x - 2) = 100 is the same as 2 (x - 2) = 50 when the former equation is being divided by 2.
Therefore, the equation 4 (x - 2) = 100 is a true equation for x when x = 27
