We have to express the number 304,800,400 in standard and expanded form.

The expanded form is shown as a sum of each digit multiplied by its matching place value. Let us express the number in expanded from.

So, 304,800,400 = (3 \times 100000000) + (4 \times 1000000) + (8 \times 100000)+ (4 \times 100)

= 300000000 + 4000000 + 800000+400

So, this is the expanded form of the given number.

Standard form is a way of writing down very large or very small numbers easily.

The standard from of the number is:

304,800,400 = 3.048004 \times 10^8.

Given :

f(x) =  {x}^{3}  + 2 {x}^{2}  + 3x + 1

g(x) = 4x - 5

let's solve for f(x) × g(x) :

( {x}^{3}  + 2x {}^{2}  + 3x + 1)(4x - 5)

4x {}^{4}  - 5 {x}^{3}  + 8 {x}^{3  }  - 10 {x}^{2}  + 12 {x}^{2}  - 15x + 4x - 5

4 {x}^{4}  + 3 {x}^{3}  + 2 {x}^{2}   - 11x - 5

therefore, correct choice is : D

If Santiago wanted to turn his $279.89 into as many nickels as possible, how many would he<br>have?​
Elina [12.6K]

Answer:

5,597 nickels and 4 pennies

Step-by-step explanation:

First, we can take away 4 cents since we know 4 isn't divisible by 5.

Our new number would be 279.80

Then, we divide 279.80 by 0.05 since 0.05 is what a nickel equals>

279.85/0.05 = 5597

Therefore, he would have 5,597 nickels and 4 pennies.

What is 1.83 repeating as a fraction?
maks197457 [2]
The answer to this question would be: 1 5/6

To change a decimal number into fraction, you need to divide the number on the right of decimal point with 1. In this case, the number is 0.83.
This number is hard since .83 doesn't have many factors. To find the answer you can try to multiply the decimal with some number until it close to 1(no decimal left)
0.83* 2= 1.66
0.83* 3= 2.49 ---> close to half, if you find this number, you can try to double it
0.83* 4= 3.32
0.83* 5= 4.15
0.83* 6= 4.98---> close to 1, that means there is high probability that the number can be divided by 6 
0.83 would be 4.98/6, but if we assume that the number is 0.8333...... then 0.83 would be 5/6. So, 1.83 would be 1 5/6
