Q:
What is \( 15 \% \) of 200 ?
Q:
13. Solve the following inequality:
\( \frac{2}{3}(6 x-9)+4>5 x+1 \).
(A) \( x>6 \)
Q:
How many \( \mathrm{mg} / \mathrm{ml} \) does a \( 2.5 \% \) solution contain?
Q:
A power line is to be constructed from a power station at point \( A \) to an
island at point C , which is 4 mi directly out in the water from a point B
on the shore. Point \( B \) is 8 mi downshore from the power station at \( A \). It
costs \( \$ 2800 \) per mile to lay the power line under water and \( \$ 2000 \) per
mile to lay the line under ground. At what point S downshore from A
should the line come to the shore in order to minimize cost? Note that
S could very well be B or A . (Hint. The length of CS is \( \sqrt{16+\mathrm{x}^{2}} \).)
Q:
Simplify the algebraic expression completely.
\[ \sqrt[3]{54 x^{4} y^{6}}-\sqrt[3]{24 x^{3} y^{9}}+\sqrt[3]{128 x^{4} y^{6}} \]
A \( \quad x^{2} y^{3} \sqrt{6}+8 x^{2} y^{3} \sqrt{2}-4 x y^{4} \sqrt{6 x y} \)
B \( 7 x y^{2} \sqrt[3]{2 x}-2 x y^{3} \sqrt[3]{3} \)
C \( 7 x^{2} y^{4} \sqrt[3]{2 x}-2 x y^{3} \sqrt[3]{3} \)
D \( \sqrt[3]{158 x^{5} y^{3}} \)
Q:
b) Avrunda 247 till tiotal
Q:
Welcher Bruch ist grösser? Notiere den grösseren Bruch.
Schreibe deinen Rechenweg oder deine Überlegungen auf.
\( \begin{array}{lll}\text { a } \frac{2}{3} \text { oder } \frac{5}{6} & \text { b } \frac{2}{3} \text { oder } \frac{3}{5} & \text { C } \frac{3}{4} \text { oder } \frac{7}{10}\end{array} \) d \( \frac{13}{8} \) oder \( \frac{10}{6} \)
Q:
Match the polynomial expression on the left with the simplified version on the right.
\( (n-2)^{2} \)
\( \begin{array}{l}(n+2)(n-2) \\ n^{2} \\ n^{2}+4 \\ n^{2}-4 \\ n^{2}-4 n+4 \\ \\ n^{2}-2 n-4\end{array} \)
