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 .

Answers

8.76 x 10^6 is 10,000 times greater than 8.76 x 10^2.

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].

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

Answers

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.

A store manager timed Janette to see how long it would take her to fold and put away a sweater, a shirt, a pair of pants, and a scarf. It took her 26.1 seconds for the shirt, 24.3 seconds for the sweater, 32.8 seconds for the pants, and 18.2 seconds for the scarf. What was the average time it took Janette to fold and put away all four items?

Answers

The Average, or the mean of the times, is the sum of the times divided by the number of times.

26.1 + 24.3 + 32.8 + 18.2 = 101.4
101.4 / 4 = 25.35 seconds.

25.35 seconds is the average

25.35 seconds.
26.1+24.3+32.8+18.2=101.4
101.4/4 (the number of items)=25.35 per each item

36 is 75% of what number

Answers

The answer should be 48

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.

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?

Answers

3/9 will fit on one bus so it will take 3 buses to fit 9/9 of the students, which 9/9 is the whole 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.

To find 12 times 13, I double 13 and halve 12 and then multiply

Answers

No just multiply them 12 times 12 is 144 just add 12 so it could be 12 times 13 and it would be 156

13
x12
——-
26
+130
——-
156

So first you do the back of 12, 2 times the back of 13, which is 6. Then the back of 12, 2 times the front of 13, which is 2. So you get 26. Then you go to the next line and put a zero, then the same thing as you did with the back of 12, but with the front, which is 1. So 1 times 3 and 1 times 1, so you get 13 and the zero you added earlier, 130. So you get 26 and 130, add them to get 156.

She needs [tex] \frac{1}{2} [/tex] yard piece, which is [tex] \frac{4}{8} [/tex] if you multiply the numerator and the denominator for [tex] \frac{1}{2} [/tex].
Now that all the numbers have the same denominator, you can subtract the numerators which is: 6 - 4 - 3 = -1

Use complete sentences to describe why postulates are helpful.

Answers

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 .
