Multiplication/division and addition/subtraction are in no particular order; solve from left to right.

6 × 10⁸

Exponents first. Find 10 to the 8th power. Move the decimal (imaginary decimal in front of the 0 in 10) 8 places to the right.

6 × 1,000,000,000

Now multiply 6 by 10⁸.

6,000,000,000 is the answer to 6 × 10⁸.

Now let's solve 3 × 10⁶

Exponents first; solve 10 to the 6th power. Move the decimal point at the front 6 places to the right.

3 × 10,000,000

Multiply.

30,000,000 is the answer to 3 × 10⁶.

Compare both answers: 6,000,000,000 and 30,000,000

Looking at them, you can see that 6 billion has 9 zeros and 30 million has 7 zeros.

Each zero counts for 100; 9 - 7 = 2 (or you can use a calculator to solve 6,000,000,000 ÷ 30,000,000)

You can conclude that 6 × 10⁸ is B) 200 times larger than 3 × 10⁶.

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b

$15.40 per mile

step-by-step explanation:

you have to round up to 4 because 6 is over 5 so you have to round the 3 up to 4
