The numbers as powers of 5 are 5^-1, 5^-2, 5^-3 and 5^0

The numbers are given as:

• 0.2

• 0.04

• 125^-1

• 15^0

Number 1: 0.2

Express as fraction

1/5

Apply the power rule of indices

5^-1

Number 2: 0.04

Express as fraction

1/25

Express 25 as 5^2

1/5^2

Apply the power rule of indices

5^-2

Number 3: 125^-1

Express as fraction

1/125

Express 125 as 5^3

1/5^3

Apply the power rule of indices

5^-3

Number 4: 15^0

Evaluate the exponent

15^0 = 1

Express 1 as 5^0

15^0 = 5^0

Hence, the numbers as a power of 5 are 5^-1, 5^-2, 5^-3 and 5^0

The unknown number is 8.

Let the unknown number be x.

According to the given question.

We have a phrase "Triple a number decreased by 25 is equivalent to five less than half the same number".

Therefore, the equation for the phrase "Triple a number decreased by 25 is equivalent to five less than half the same number" is given by

3x - 25 = x/2 - 5

To find the unknown number we have to solve the above equation for x.

Therefore,

3x - 25 = x - 10/2

⇒ 6x - 50 = x - 10

⇒ 6x - x = -10 + 50

⇒ 5x = 40

⇒ x = 40/5

⇒ x = 8

Hence, the unknown number is 8.

There are four levels of measurements in statistics, namely nominal, ordinal, interval, ratio. These levels are important when it comes to analyzing data, since it helps us determine the technique that we can use to support or refute our study.

In the nominal level, we can categorize data but they cannot be ranked. An example would be hair color. In an ordinal data, the data can be both categorize and ranked, but doing mathematical calculation may not make sense. Also, the intervals between rankings doesn't necessarily dictate how close or far apart the data are.

A good example is level of education. In an interval level, the data can be categorized, ranked, and measured but they do not have a true zero. An example could be a range of values that does not include zero. Lastly, in the Ratio level the data can be categorized, rank, and measured, and it has a true zero.

So ratio level is most appropriate for ages of children. Note that ages can be categorized, rank, and measured .Moreover, an age equal to zero means that there is no age or the absence of age.

Step-by-step explanation:

prime factorization: 2^3×3×7 which has: 2, 3, 4, 6, 8

Answer:

It is divisible by 1, 2, 3, 4, 6, 7, 8

Step-by-step explanation:

Everything is divisible by one, so this is obvious.

168 is an even number, therefore being able to be divided by 2

1+6+8=15 which is in the 3 times tables (3x5=15)

If the last two digits are divisible by 4 (which 68 is) then you can divide it by 4.

168 doesn't end in 5 or 0 so it can't be divided by 5

This number can be divisible by 2 and 3 so it can be divided by 6

160 is divisible by 8 so if you add 8 it is divisible.

1+6+8=15 again which is not divisible by 9

It doesn't end in 0 meaning it cannot be divisible by 10

Answer:

C. 20

Step-by-step explanation:

Use the Pythagorean theorem which is [tex]a^{2} +b^{2} =c^{2}[/tex].

[tex]a^{2}[/tex] and [tex]b^{2}[/tex] are the sides of the triangle squared, AB and AC. [tex]c^{2}[/tex] is the hypotenuse (the slanted side of the triangle) or BC.

So, [tex]12^{2} + 16^{2} =400^{2}[/tex]. Then you square root 400 to get your answer.

[tex]\sqrt{400}[/tex] = 20.

20 is your answer.

Considering that the transformation is a dilation, the correct statement is given by:

The angles of Quadrilateral ABCD and A'B'C'D' are the same.

There are three statements:

A figure is said to go through a dilation is when it's side lengths are changed, either enlarged or diminished, but the angles remain constant.

For this problem, the scale factor is of 2, meaning that the side lengths are doubled, while the angles remain constant and the correct statement is:

Price: $178.57

30% off: -$53.57

Sale Price: $125.00

Step-by-step explanation:

She buys each shirt for $100.

She wants to make a profit of 25%.

25% of $100 = 0.25 × $100 = $125

She must sell the shirt at $125.

She wants to mark the shirt at a higher price than $125, so that after the 30% discount, she will still sell it for $125.

Call the higher price x.

x - 30% of x = 125

x - 0.3x = 125

0.7x = 125

x = 125/0.7

x = 178.57

The sale tag can read:

The equation of the line is y = -7.5x - 2.5

The given parameters are

y-intercept = -5/2

x-intercept = -1/3

A linear equation is represented s

y = mx + c

Where

c = y-intercept = -5/2

So, we have:

y = mx - 5/2

The equation x-intercept = -1/3 means that

y = 0 and x = -1/3

So, we have

0 = -1/3m - 5/2

This gives

1/3m = -5/2

Evaluate

m = -15/2

Substitute m = -15/2 in y = mx - 5/2

y = -15/2x - 5/2

Rewrite as

y = -7.5x - 2.5

Hence, the equation of the line is y = -7.5x - 2.5
