Write an expression using the distributive property that can be used to find the quotient of 126 divided by 7

Answers

Answer 1

Answer: Well, let's discover how many times 7 goes into 126 first.

7 x 11 = 77
7 x 12 = 84
7 x 13 = 91
7 x 14 = 98
7 x 15 = 105
7 x 16 = 112
7 x 17 = 119
7 x 18 = 126

Well, 7 goes into 126 - 18 times - therefore the quotient is 18. The use of the distributive property wouldn't be necessary.

Nevertheless, you could say that:

$\frac { 126 }{ 14 } \n \n =\frac { 140-14 }{ 7 } \n \n =\frac { 140 }{ 7 } -\frac { 14 }{ 7 } \n \n =20-2\n \n =18$

* I've used the distributive property above.

Solve:-10²
23³
14³
52²

I don't know how to do this. please Help! Thanks in advance.

Answers

10^2 = 10 × 10 = 100

23^2 = 23 × 23 × 23 = 12167

14^3 = 14 × 14 × 14 = 2744

52^2 = 52 × 52 = 2704

These are exponents. To solve d exponents we will multiply d base itself how many times it says to in d exponent.

a^b

a = base
b = exponent

10²

10 = base
2 = exponent

10² = 10 × 10 = 100
10² = 100

23³

23 = base
3 = exponent

23² = 23 × 23 × 23 = 12167
23² = 12167

14³

14 = base
3 = exponent

14³ = 14 × 14 × 14 = 2744
14³ = 2744

52²

52 = base
2 = exponent

52² = 52 × 52 = 2704
52² = 2704

So:-

10² = 100
23² = 12167
14³ = 2744
52² = 2704

The area of Asia is about 44,600,000 square kilometers. The area of Europe is about 9.94 x 10^6 square kilometers. What is the combined area of Asia and Europe?a. 1.44 x 10^6 square kilometers

b. 5.454 x 10^6 square kilometers

c. 1.44 x 10^7 square kilometers

d. 5.454 x 10^7 square kilometers

Answers

Answer:

d. 5.454 x 10^7 square kilometers

Step-by-step explanation:

Adding 4.46×10^7 to 0.994×10^7 we get 5.454×10^7.

___

Before you can add numbers in scientific notation, they must both have the same multiplier. Here, we can see that the area of Asia will be written with an exponent of 7, so we choose to write both numbers that way.

44,600,000 = 4.4×10,000,000 = 4.4×10^7

9.94×10^6 = (0.994×10)×10^6 = 0.994×10^7

The sum is (4.400 +0.994)×10^7 = 5.454×10^7.

Combined area is 5.454 × 10^7 km²

Step-by-step explanation:

Step 1: Find the combined area of Asia and Europe.

Area of Asia = 44,600,000 km²

Area of Europe = 9,943,106 km²

⇒ Combined Area = 44,600,000 + 9,943,106

= 54,543,106 km²

Step 2: Convert to one significant figure.

54,543,106 = 5.454 × 10^7 km² (Dividing and multiplying by 10^7)

How you be a very good maths improver

Answers

In order to improve in your math skills you have to study.
I know from experience.
You can get a tutor like I did. Some help some dont so choose wisely.
You should print out worksheets from online, if you dont have a printer just copy the question onto a piece of paper.
STUDY!
Everyday when you come home from school, review what you have done during math class so if you forgot some of it you refresh your mind. Do the same thing before you go to sleep.
Hope I helped!

Study by finding online games and printing out worksheets. Ask your parents or guardian to quiz you and MAKE FLASHCARDS! It helps so much. When you have a spare 5 minutes pull them out and study. Take extra notes in class than your teacher wants you to and rewrite them and highlight them. Find workbooks around your house. Ask your parents/guardian to make a math test for you or just print one out. Don't stress yourself with math, take a 10 minute break before doing more every 30 minutes. I used to HATE MATH but now it's ok because I do these things. MATH IS FUN!!!!
