Answer:

35

Step-by-step explanation:

We know that the numbers have to be in ascending order. If, for example, the first digit is 0, and second digit is 1, then we would have 5 other numbers in the ones place that would be larger. If the second digit is 2, then would would have 4 other numbers that would be larger, and so on. So if 0 is the first digit, then we would have 5+4+3+2+1=15 combinations. If 1 is the first digit, then we would have 4+3+2+1 combinations. Eventually, we would get 35.

express 121,200 in exponential (powers of 10) notation. express the earth sun distance in kilometers in powers of 10 notation.

Mashutka [201]

The exponential form of given number 121200 is 1.212 × $10^5$

And the earth sun distance in kilometers in powers of 10 notation is 1.5 × $10^8$

For given question,

We need to express 121,200 in exponential (powers of 10) notation.

To use scientific notation, pick a value between 1 and 10, then multiply it by 10ˣ.

The number between 1 and 10 in 121200 is 1.212 with 5 decimal points.

So, the exponential notation of given number would be,

121,200 = 1.212 × $10^5$

Earth's average distance from the Sun is around 93 million miles (150 million kilometers). That's one AU.

So the number between 1 and 10 in 150,000,000 is 1.5, with 8 decimal points.

So, the distance between he Earth and the Sun is:

150,000,000 = 1.5 × 10⁸

Therefore, the exponential form of given number 121200 is 1.212 × $10^5$

And the earth sun distance in kilometers in powers of 10 notation is 1.5 × $10^8$

Write the values in the boxes that make the statement true

Answer:

$\frac{5}{3}xz^8*9x^6y^0z^2 = 15x^7z^{10}$

Step-by-step explanation:

<u>Given</u>

$\frac{5}{3}xz^a*bx^cy^dz^2 = 15x^7z^{10}$

<u>Simplify</u>

$\frac{5}{3}b*x^{1+c}z^{a+2}y^d = 15x^7z^{10}y^0$

Compare left and right sides and

<u>Find b:</u>

<u /> $\frac{5}{3}$ b = 15 ⇒ b = 15*3/5 = 9

<u>Find c:</u>

1 + c = 7 ⇒ c = 7 - 1 = 6

<u>Find a:</u>

a + 2 = 10 ⇒ a = 10 - 2 = 8

<u>Find d:</u>

d = 0

<u>Solution is:</u>

$\frac{5}{3}xz^8*9x^6y^0z^2 = 15x^7z^{10}$
