Answer:

i believe the answer is x=6

Step-by-step explanation:

12x + 4 = 2(5x + 8)

12x + 4 = 10x + 16

12x - 10x = 16 - 4

2x = 12

2x/2=12/2

x=6

Answer: 14n ,-18

Answer:

We can say we start with 490 grams and after 1 year we have (490 * .81 grams) or 396.9 grams.

We can solve for half-life by this equation:

Half life = (time * log 2) / log (beginning amount / ending amount)

Half-life = (1 year * 0.30102999566) / log (490 / 396.9)

Half life = (1 year * 0.30102999566) / log (1.2345679012 )

Half life = (0.30102999566) / 0.091514981109

Half-Life = 3.2894067399  years

Well, that's a start.

Step-by-step explanation:

The half life of the given radioactive isotope will be 3.2894067399  years.

The amount of time it takes to disintegrate by half an initial amount. For a given reaction, a reactant's half-life t-1/2 is the time it takes for its concentration to reach a value which is the arithmetic mean of its initial and final value.

Here, Element X starts with 490 grams

After 1 year we have  (490 X 0.81 grams) or 396.9 grams

Now, We can solve for half-life by this equation:

Half life = (time  X log 2) / log (beginning amount / ending amount)

Half-life = (1 year X 0.30102999566) / log (490 / 396.9)

Half life = (1 year X 0.30102999566) / log (1.2345679012 )

Half life = (0.30102999566) / 0.091514981109

Half-Life = 3.2894067399  years

Thus, the half life of the given radioactive isotope will be 3.2894067399  years.

Answer:

Slope= 4

Step-by-step explanation:

When you start at (0, 0) and then go to (1, 4), then you have to use the slope.

So, to figure out the slope, you have to do rise over run, rise/run.

So, as shown in the graph, the rise is 4 because the rise is the y so to get from 0 to 4, you have to add 4.

And the run, which would be the x side is 1 because to get from 0 to 1. You add 1.

This shows us that the slope is 4/1 which could be simplified to just 4.

Answer:

64/2 or 64 I hope this helps

Answer:

A: 32, B: 18

Step-by-step explanation:

For A, we multiply 8 by 8 (8 to the second power). From that, we get 64, now, we put that over 2, so now we have 64/2. We can simplify this, though, just divide both numbers by two to get 32/1, or just 32. For B, we know that x=6, so we put that in the equation, 30 - (2x6). We can simplify that to 30 - 12. When we solve this, we get 18. I hope this helps!

Answer: First Option (5√5)

Answer:

First, you see if there are any perfect squares that are a factor of 125. If you do find some, find what is seemingly the biggest. In this case, it is 25, I think. So you can then out it as root(25×5), I think. As 25 is a perfect square, you can square and then put the number you get on the outside. So since 5×5=25, it becomes 5(root)5, which essentially means 5×(root)5, I think.

Answer: 6) 15 1/10

Step-by-step explanation:

Add the whole numbers and then find a common number for the bottom fraction. So that'd be ten. To get to ten from 2 you'd multiply by five then multiply the top number by five too. That gets you 5/10 and do the same for the other fraction. Get the bottom number to ten then whatever you multiply by do the same to the top. After doing that putting the fractions together which gets you 11/10. That'd make 1 1/10 so that makes it 15 instead of 14 whole

Based on the calculations, the value of x for this regular polygon with the given interior angle is equal to 3.

A polygon can be defined as a two-dimensional geometric shape that comprises straight line segments and a finite number of sides. Also, some examples of a polygon include the following:

Note: The number of sides (n) of a hexagon is 6.

In Geometry, the sum of the interior angles of both a regular and irregular polygon is given by this formula:

Sum of interior angles = 180 × (n - 2)

Sum of interior angles = 180 × (6 - 2)

Sum of interior angles = 180 × 4

Sum of interior angles = 720°.

Next, we would determine the value of x by using this formula:

Interior angle × Number of sides = Sum of interior angles

Substituting the parameters into the formula, we have;

(-134x + 516 + 2x) × 6  = 720

-134x + 516 + 2x = 720/6

-134x + 516 + 2x = 120

516 - 120 = 134x - 2x

396 = 132x

x = 396/132

x = 3.
