Answer: $20,000,000+400,000+80,000+4,000+100+60+3$

Step-by-step explanation:

In Mathematics, expanded form is a general representation of writing numbers according to their place value of individual digits.

Given : In 2008, the population of 10-to 14-years-old in the United States was 20,484,163.

From Right , Place value of 3 = 3 ones or 3

Place value of 6 = 6 tens or 60

Place value of 1 = 1 hundreds or 100

Place value of 4 = 4 thousands or 4,000

Place value of 8 =8 ten thousands or 80,000

Place value of next 4 = 4 hundred thousands or 400,000

Place value of 0 = 0 million

Place value of 2 = 2 ten million or 20,000,000

Now, the expanded form of $20,484,163=20,000,000+400,000+80,000+4,000+100+60+3$

Or 2 ten millions+4 hundred thousands+8 ten thousands+4 thousands+1 hundreds+ 6 tens+3 ones.

ANSWER

$y = 3x - 3$

EXPLANATION

Let

$y = mx + c$

be the equation.

We can choose any two ordered pairs to determine the equation of the relation.

$(6,15) \: and \: (8,21)$

We find m using the formula;

$m = \frac{y_2-y_1}{x_2-x_1}$

$m = \frac{21 - 15}{8 - 6} = \frac{6}{2} = 3$

The equation becomes

$y = 3x + c$

When x=6, y=15.

This implies that,

$15 = 3(6) + c$

$15= 18 + c$

$15 - 18= c$

$c = -3$

The equation of the relation is therefore,

$y = 3x -3$

Which are the roots of the quadratic function f(b) = 62 – 75? Select two options.

elena55 [62]

Answer:

$b = 5 \sqrt{3} \ or\ b = -5 \sqrt{3}$

Step-by-step explanation:

Given

$f(b) = b^2 - 75$

Required

Determine the roots

To get the root of the function, then f(b) must be 0;

i.e. f(b) = 0

So, the expression becomes

$0 = b^2 - 75$

Add 75 to both sides

$75 + 0 = b^2 - 75 + 75$

$75 = b^2$

Take square roots of both sides

$\sqrt{75} = \sqrt{b^2}$

$\sqrt{75} = b$

Reorder

$b = \sqrt{75}$

Expand 75 as a product of 25 and 3

$b = \sqrt{25*3}$

Split the expression

$b = \sqrt{25} *\sqrt{3}$

$b = \±5 *\sqrt{3}$

$b = \±5 \sqrt{3}$

$b = 5 \sqrt{3} \ or\ b = -5 \sqrt{3}$

The options are not clear enough; however the roots of the equation are $b = 5 \sqrt{3} \ or\ b = -5 \sqrt{3}$

Seven cereal bars are shared equally by 3 students. How many does each student receive?I really need help and my teacher won't h

Katarina [22]

Answer:

Each student gets 2 1/3

Step-by-step explanation:

So you would divide 7 by 3, which you can't...so 6 divided by 3 is 2, and when you split the last one into thirds you can each have 1/3. Add the sections together, and each person gets 2 1/3
