Find the measure of the missing angles.
Verdich [7]

Answer:

x = 57                y = 137

Step-by-step explanation:

x + 43 + 90 = 180

x + 43 + 90 - 90 = 180 - 90

x + 43 = 90

x + 43 - 43 = 90 - 43

x = 57

43 + y = 180

43 + y - 43 = 180 - 43

y = 137

Which expression is equivalent to StartFraction (5 a b) cubed Over 30 a Superscript negative 6 Baseline b Superscript negative 7
m_a_m_a [10]

Answer:

Option D.

Step-by-step explanation:

The given expression is

\dfrac{(5ab)^3}{30a^{-6}b^{-7}}

We need to find the expression, which is equivalent to the given expression.

The given expression can be rewritten as

\dfrac{5^3a^3b^3}{30a^{-6}b^{-7}}     [\because (ab)^m=a^mb^m]

\dfrac{125}{30}\times \dfrac{a^3}{a^{-6}}\times \dfrac{b^3}{b^{-7}}

\dfrac{25}{6}\times a^{3-(-6)}\times b^{3-(-7)}    [\because \dfrac{a^m}{a^n}=a^{m-n}]

\dfrac{25}{6}\times a^{3+6}\times b^{3+7}

\dfrac{25a^9b^{10}}{6}

Therefore, the correct option is D.
