Element X decays radioactively with a half life of 6 minutes. If there are 260 grams of Element X, how long, to the nearest tenth of a minute, would it take the element to decay to 113 grams

Answers

Answer:

7.2 minutes

Step-by-step explanation:

The formula to find the time using the radioactive decay rate formula is given as:

t = t½ × In(Nt/No)/-In2

Where

t½ = half life = 6 minutes

No = Initial Amount = 260 grams

Nt = Amount after decay

= 113 grams

Hence:

t = 6 × In(113/260)/-In2

t = 7.2131331036796 minutes

Approximately = 7.2 minutes

3.6x+5.9−2.2−1.7x

Answers

Answer:

1.9x+3.7

Step-by-step explanation:

Subtract 3.6x-1.7x

and 5.9-2.2    

The solution is 1.9x + 3.7

The value of the equation is given as A = 1.9x + 3.7

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

A = 3.6x + 5.9 - 2.2 - 1.7x   be equation (1)

On simplifying the equation , we get

On grouping the similar terms

The value of A = ( 3.6x - 1.7x ) + ( 5.9 - 2.2 )

The value of A = 1.9x + 3.7

Therefore , the value of A is 1.9x + 3.7

Hence , the equation is A = 1.9x + 3.7

Solve the equation below for x.
0.5(x + 7) + 9 = 43

Answers

Answer:

x = 61

Step-by-step explanation:

0.5(x + 7) + 9 = 43

0.5x + 3.5 + 9.0 = 43

0.5x + 12.5 = 43.0

0.5x = 30.5

x = 30.5 / 0.5

x = 61

The solution to the value of x in the equation is 61

In a mathematical concept, an algebraic expression consists of variables, constants with their arithmetic operations.

From the given parameters

0.5(x + 7) + 9 = 43

Open brackets

0.5x + 3.5 + 9 = 43

0.5x + 12.5 = 43

0.5x = 43 - 12.5

0.5x = 30.5

x = 30.5/0.5

x = 61

A rectangular table top has dimensions as 1.52m and 0.75m. Find the perimeter in cm

Answers

That is a question about perimeter of rectangle.

The perimeter of a geometric shape is the sum of the value of the all sides.

In a rectangle, the opposite sides are cogruentes (equals). For example, look at picture below. In that rectangle, the sides AB and DC are equals, and the sides AD and BC are equals.

So, the sides of that rectangular table are: 1.52m, 1.52m, 0.75m and 0.75.

Therefore, the perimeter of that rectangle is [tex]1.52+1.52+0.75+0.75= 4.54[/tex]m.

But that is not the final answer because that is the perimeter in meters and the question want the answer in centimeters.

1 meter has 100 centimeter, so we need to multiplicate the perimeter by 100.

Thus, the perimeter of that rectangular table is [tex]4.54\cdot 100 = 454[/tex]cm.

Answer:

How many plates are on the table as it results in only one value with no variability

Step-by-step explanation:

D) How many plates are on the table? is not a statistical question because it does not involve the collection or analysis of numerical data.

What is Statistic?

A statistic is a piece of data derived from a subset of a population. It's the inverse of a parameter — census data, which polls everyone.

Statistics is a method of comprehending data collected about us and the world. For example, if you send a parcel through the mail, it is logged in a massive database.

How many plates are on the table? is not a statistical question because it does not involve the collection or analysis of numerical data.

A statistical question involves the collection and analysis of numerical data in order to make inferences or draw conclusions about a larger population.

The other questions (A, B and C) all involve the collection and analysis of numerical data and are therefore statistical questions.

Hence, the correct answer would be option (D).
