If a spinner is divided into 2 sections is spun 5 times, how many outcomes are possible?
Karo-lina-s [1.5K]
The final number of outcomes would end up being 10 possible outcomes because you would do five and multiply it by two. And there would be a possibility of landing on any of ten outcomes. Hope I helped reassure you of your answer :)

Mags is 2 years older than vector . if mags is 34 years old how old is vector
lord [1]

Answer:

Vector is 32 years old.

Step-by-step explanation:

As it is given that Mags is 34 years old and he is 2 years older than Vector.

Since Mags is 2 years older than Vector, Vector's age is 2 year less than Mags.

therefore we subtract 2 years from the age of Mags.

= 34 - 2 = 32 years

So Vector is 32 years old.

NO LINKS AND NO ANSWERING WHAT YOU DON'T KNOW!!! THIS IS NOT A TEST OR ASSESSMENT!!!
Reptile [31]

Answer:

Part 1)

1) Sylvia' process was incorrect. In her last step, when she multiplied 0.88 by 10, she also need to divide exponent by 10.

2) Dylan is perfectly correct.

3) Ethan's process was also incorrect. Instead of subtracting the exponents, he added them.

Part 2)

Only Skyler's approach was incorrect. When Skyler acquired (3⁶)ˣ = 9, he made the error of setting the exponent on the left to the value on the right.

Step-by-step explanation:

Part 1)

We want to simplify the expression:

\displaystyle \frac{3.61\times 10^{-11}}{4.1\times 10^7}

We can divide. Recall that <em>xᵃ </em>/ <em>x</em>ᵇ = <em>x</em>ᵃ ⁻ ᵇ. Hence:

\displaystyle =0.88\times 10^{-11-7}=0.88\times 10^{-18}

In scientific notation, the coefficient is always between 1 or 10.

So, we can multiply 0.88 by 10. To keep the equality, we need to divide 10⁻¹⁸ by 10. Hence:

\displaystyle =0.88(10)\times \frac{10^{-18}}{10}

(You can see that the 10s can cancel out, giving us our original expression.)

Simplify. Thus:

\displaystyle \frac{3.61\times 10^{-11}}{4.1\times 10^7} = 8.8\times 10^{-19}

Therefore, as we can see:

1) Sylvia' process was incorrect. In her last step, when she multiplied 0.88 by 10, she also need to divide exponent by 10.

2) Dylan is perfectly correct.

3) Ethan's process was also incorrect. Instead of subtracting the exponents, he added them.

Part 2)

Reviewing their work, we can see that only Skyler's approach was incorrect.

729 is indeed 3⁶. However, when Skyler acquired (3⁶)ˣ = 9, he made the error of setting the exponent on the left to the value on the right.

Both Robert and Kevin are correct, having set each exponent equal to each other after their bases are equivalent and solving for <em>x</em>.
