Answer:

$\large\boxed{0.000008=8\cdot10^{-6}}$

Step-by-step explanation:

The scientific notation:

$a\cdot10^k$

where 1 ≤ a < 10 and k ∈ Z.

0.000008

You must move the comma 6 places to the right.

$0\underbrace{.000008}_{6\rightarrow}=8\cdot10^{-6}$

$0.000008=\dfrac{8}{1,000,000}=8\cdot10^{-6}$

Answer:

3x² * (6x² + 4x - 8) = 18x⁴ + 12x³ - 24x²

2x * (9x³ + 6x² - 12x) = 18x⁴ + 12x³ - 24x²

x² * (18x² + 12x - 24) = 18x⁴ + 12x³ - 24x²

6x² * (3x² + 2x - 4) = 18x⁴ + 12x³ - 24x²

Step-by-step explanatation:

Let's set unknown variables as y (and y₁, y₂, etc)

Question 1:

y * (6x² + 4x - 8) = 18x⁴ + 12x³ - 24x²

So, divide both sides by (6x² + 4x - 8)

y = 3x²

Question 2:

2x * (9x^y₁ + y₂*x^y₃ - y₄*x) = 18x⁴ + 12x³ - 24x² '

Divide both sides by 2x.

(9x^y₁ + y₂*x^y₃ - y₄*x) = 9x³ + 6x² -12x

y₁ = 3, y₂ = 6, y₃ = 2, y₄ = 12

Question 3:

x^y * (18x² + 12x - 24) = 18x⁴ + 12x³ - 24x²

Divide both sides by (18x² + 12x - 24)

x^y = x²

Question 4:

y₁ * x^y₂ * (3x² + 2x - 4) = 18x⁴ + 12x³ - 24x²

Divide both sides by (3x² + 2x - 4)

y₁ * x^y₂ = 6x²

y₁ = 6, y₂ = 2

I hope this helps! Feel free to ask any questions!

Eliah bought 1.87 pounds of chicken and 2.46 pounds of turkey at the deli. About how many pounds of meat did he buy?

mart [117]

So,

If this was mental math, I would round 1.87 to the nearest pound and 2.46 to the nearest half pound, making the following addition problem:
2 + 2.5 = 4.5
Because 1.87 is closer to 2 than to 1.5 or 1, and 2.46 is sooo close to 2.5.
So I would say about 4.5 pounds of meat.

But if you're rounding to the nearest pound for both, then you have this equation:
2 + 2 = 4
Because in 1.87, 8 is greater than or equal to 5, and in 2.46, 4 is less than or equal to 5.
So in that case, it would be about 4 pounds of meat.

Alexis is knitting a blanket 2 meters long. Every 2 decimeters, she changes the color of the yarn to make stripes. How many stri

hjlf

Answer:

There are 10 stripes in the blanket.

Step-by-step explanation:

We are given the following in the question:

Length of blanket = 2 meters

1 meter = 10 decimeter

Length of blanket in decimeter =

$2\times 10 = 20\text{ decimeters}$

Change of color = Every 2 decimeters.

Number of stripe =

$=\dfrac{\text{Length of blanket}}{\text{Length of change of color of stripe}}\\\\=\dfrac{20}{2} = 10$

Thus, there are 10 stripes in the blanket.
