Answer:
8.55 x 10^-5
Step-by-step explanation:
we need to write 0.0000855 in scientific notation
To get the number in scientific notation, we need to move the decimal point after the first number
To get the decimal number after the first number we move the decimal point 5 places to the right
0.0000855 becomes 00008.55
We moved 5 places to the right, so we multiply by 10^-5
[tex]8.55 \cdot 10^{-5}[/tex]

Use complete sentences to describe why postulates are helpful.
Answer:
Postulates are the base structure of Mathematics.Step-by-step explanation:
Postulates are suggestion or assumptions that something is true based on reasoning, for example, the definition of a point in Euclidian Geometry.
Therefore, mathematics is grounded in systems of postulates that are tacitly true. Those postulates are used to define and demonstrate theorems, which are the strong structure of every law in Mathematics.
The postulates are helpful as they are taken to be true without proof and are basic structure from which lemmas and theorems are derived .
What are postulates?A statement, also known as an axiom, which is taken to be true without proof. Postulates are the basic structure from which lemmas and theorems are derived. The whole of Euclidean geometry, for example, is based on five postulates known as Euclid's postulates.
According to the question
Postulates are helpful because they are basic structure from which lemmas and theorems are derived and they are also known as an axiom, which is taken to be true without proof.
Hence, postulates are helpful as they are taken to be true without proof and are basic structure from which lemmas and theorems are derived .

James is reading the latest book by his favorite science fiction author. The table shows the number of pages James read over different periods of time. Calculate the proportionality constant from the table in terms of pages per minute.
A) 0
B)1/2
C)8
D)12
Time (minutes)8 16 24
Pages Read 4 8 12
The proportionality constant from the table in terms of pages per minute is 1/2.
option B.
What is the proportionality constant ?The proportionality constant from the table in terms of pages per minute is calculated by applying the following formula.
The given time and pages read are;
Time (minutes)-------- 8 16 24
Pages Read ----------4 8 12
Mathematically, the formula for the proportionality constant is given as;
proportionality constant = pages read / time taken
proportionality constant = 4 pg / 8 min = 8 pg / 16 min = 12pg / 24 min
proportionality constant = 1/2 pg/min = 1/2 pg/min = 1/2 pg/min
Thus, the proportionality constant from the table in terms of pages per minute is calculated by dividing the pages read by the time taken to read the pages.

What is the relationship between 8.76×106 and 8.76×102 ? Select from the drop-down menus to correctly complete the statement. 8.76×106 is times than 8.76×102 .
Answer:
[tex]8.76\times 10^6[/tex] is 10,000 times [tex]8.76\times 10^2[/tex].
Step-by-step explanation:
Let [tex]8.76\times 10^6[/tex] be n times [tex]8.76\times 10^2[/tex].
We have been given two numbers [tex]8.76\times 10^6[/tex] and [tex]8.76\times 10^2[/tex].
We can represent this information in an equation as:
[tex]8.76\times 10^2\cdot n=8.76\times 10^6[/tex].
[tex]\frac{8.76\times 10^2\cdot n}{8.76\times 10^2}=\frac{8.76\times 10^6}{8.76\times 10^2}[/tex]
[tex]n=\frac{8.76\times 10^6}{8.76\times 10^2}[/tex]
Using exponent property of fractions [tex]\frac{a^m}{a^n}=a^{m-n}[/tex], we will get:
[tex]n=\frac{8.76\times 10^{6-2}}{8.76}[/tex]
[tex]n=1\times 10^{4}[/tex]
[tex]n=10,000[/tex]
Therefore, [tex]8.76\times 10^6[/tex] is 10,000 times [tex]8.76\times 10^2[/tex].

A group of students and teachers are going on a field trip? One ninth of the group will fit on 1/3 of a school bus. How many buses are needed to transport the entire group?
The entire group will need 3 buses to transport them on the field trip.
How many buses will be needed?Let total number of people in the group be represented by 'P'
We are told that 1/9 of the group can fit on 1/3 of a school bus.
So, this shows 1/9 of P = (1/3) of a bus; we will write an equation to find the total number of buses needed
==>
(1/9)P = (1/3) bus
P = (1/3) bus * 9
P = 9/3
P = 3 buses.

Which table best represents the steps to solve the equation 8 + = 4?

36 is 75% of what number
The percentage is the method of distributing the numbers in a range from 0 to 100. The number 36 is 75% of 48.
To find the number that 36 is 75% off, use the following steps:
Remember that per cent means "per hundred." So, 75% can be written as the fraction 75/100 or the decimal 0.75.
Let's call the unknown number "x". We want to find the value of "x" that satisfies the equation: 36 = 0.75 * x.
To solve for "x", we need to isolate it on one side of the equation. We can do this by dividing both sides of the equation by 0.75.
36 / 0.75 = (0.75 * x) / 0.75
Simplifying the right side, we get:
36 / 0.75 = x
Evaluating the left side of the equation, we have:
48 = x
Therefore, 36 is 75% of 48.
