Answer:

9.  \frac{1}{10,000} = 0.0001

10. \frac{1}{81}

Step-by-step explanation:

9. x^{-4}

Evaluate when x = 10.

Substitute x = 10 into the expression

10^{-4}

Apply the negative exponent rule (a^{-n} = \frac{1}{a^n})

Thus:

= \frac{1}{10^4}

= \frac{1}{10^4} = \frac{1}{10,000} = 0.0001

10. 2a^{-1}b^{-3}

Evaluate when a = 6 and b = 3

Substitute

(2*6^{-1})(3^{-3})

Apply the negative exponent rule

(2*\frac{1}{6})(\frac{1}{3^3})

(\frac{2}{6})(\frac{1}{27})

\frac{2*1}{6*27}

\frac{1}{81}

<h2><u>Question</u> : 9</h2>

plugging the value of x as 10, we get

\longrightarrow\: \: x {}^{ - 4}

\longrightarrow\: 10 {}^{ - 4}

\longrightarrow \dfrac{1}{10 {}^{4} }

\longrightarrow\dfrac{1}{10000}

\longrightarrow0.0001

<h2><u>Question</u> : 10</h2>

plugging the value of

  • a as 6
  • b as 3

\longrightarrow2 {a}^{ - 1} b {}^{ - 3}

\longrightarrow2 \times 6 {}^{ - 1}  \times 3 {}^{ - 3}

\longrightarrow \dfrac{2}{6 \times 27}

\longrightarrow \dfrac{2}{162}

\longrightarrow \dfrac{1}{81}

There are 90 girls and 60 boys in the sixth grade at a middle school. Of these students, 7 girls and 2 boys write left-handed. W
Radda [10]

Answer:

6%

Step-by-step explanation:

  1. 90 + 60 = 150
  2. 7 + 2 = 9
  3. Set up a proportion: \frac{9}{150} = \frac{x}{100}  
  4. Cross multiply, then divide: 9 × 100 = 900, 900 ÷ 150 = 6
  5. So, 6% of students in 6th grade were left-handed

I hope this helps!
