Okay, so keeping mind that the equation for area is A = L x W, look at the measurements you already have. 5.5 x 10^5 is the length, and 4.2 x 10^4 is the width. Switch them into full form and use a calculator to multiply the two for the area in meters.

550000 x 42000 = 23100000000, which in scientific form is 2.31 × 10^10. So that's answer one.

For the second, in kilometers, just take the full measurement you already have, 23100000000 m, transfer it into kilometers, 23100000 km, and then find its scientific notation, 2.31 × 10^7. That's answer two.

To answer the last question for which is more suitable, just consider what number you'd prefer to look at: a bigger number or a smaller one. Since the kilometer measurement number is smaller, its correct.

Summarily, the answers are 2.31 × 10^10, 2.31 × 10^7, and square kilometers, in that order.

The number of point a baketball team cored ha 3,4, and 5 a factor. What i the leat number of point the team could have cored
Inga [223]

The least number of point the team could have scored is the LCM of the factors given = 60.

Factor 1 = 3

Factor 2 = 4

Factor 3 = 5

therefore, LCM  

= 4 * 5 * 3   [because they don't have any factors in common]

= 60

The positive integers that can divide a number evenly are referred to as factors. Let's say we multiply two numbers to produce a result. The product's factors are the number that is multiplied.

Each number has a self-referential element. There are several examples of factors in everyday life, such putting candies in a box, arranging numbers in a certain pattern, giving chocolates to kids, etc. We must apply the multiplication or division method in order to determine a number's factors.

What is the first step in simplifying the expression 11x-2-3(1-7x)^2+(x+1)?
Gennadij [26K]

Answer:

PEMDAS is a great way to figure this out!

P - Parenthesies

E - Exponents

M - Multiplcation

D - Division

A - Addition

S - Subtraction

Follow this order and you should be good to go! Here's how I would follow this in this equation.

11x-2-3(1-7x)^2+(x+1)

First, parentheses

The 3 directly next to the parenthesies shows that everything inside of the () needs to be multiplied by 3.

-3*1  and -3*-7x (don't forget the negative)

This gives us 11x-2+(-3+21x)^2+(x+1)

Now distribute the exponents to everything inside of the parentheses.

11x-2+-3^2+21x^2+(x+1)

now solve the numbers with exponents without a variable.

3^2 = 3*3 = 9

combine any numbers without a variable outside of parentheses

11x-2+9+21x^2+(x+1)

11x+7+21x^2+(x+1)

From here, what I would do is divide the whole equation by 2

5.5x+3.5+21x+(.5x+.5)

now combine x values outside of parentheses

3.5+26.5x+(.5x+.5)

I believe this would be the simplest form, but please do correct me if I'm wrong or made any errors
