Answer:

B

Step-by-step explanation:

These angles add up to 180°.

(2x + 2) + (x + 34) = 180° = 3x + 36

3x = (180 - 36)° = 144°

x = (144/3)° = 48°

Carlos is investing his money. He thinks that he should make nine dollars for every $100 he invests. How much does he expect to
Semenov [28]

Answer:

Carlos expect to make <u>$540</u> on an investments of $6000.

Step-by-step explanation:

Given:

Carlos thinks that he should make $9 for every $100 he invests.

Now, to get the amount Carlos expect to make on an investments of $6000.

Let the amount he expect to make on an investments of $6000 be x.

As, Carlos thinks that he should make nine dollars for every $100 he invests.

<em>So, $100 is equivalent to $9.</em>

<em>Thus, $6000 is equivalent to </em>x.<em />

Now, to get the amount using cross multiplication method:

\frac{100}{9} =\frac{6000}{x}

<em>By cross multiplying we get:</em>

<em />100x=54,000<em />

<em>Dividing both sides by 100 we get:</em>

x=540.

Therefore, Carlos expect to make $540 on an investments of $6000.

√3=1.732 find the value of√75+1/2√48-√198​
Nookie1986 [14]

Answer:

12.124-3\sqrt{22}

Step-by-step explanation:

\sqrt{75} = \sqrt{5^{2}*3} \\

\sqrt{48}= \sqrt{2^{2}*2^{2}*3} \\

\sqrt{198} =\sqrt{3^{2}*2*11} \\

\sqrt{75} +\frac{1}{2} *\sqrt{48} - \sqrt{198} \\\\\sqrt{5^{2}*3} +\frac{1}{2} *\sqrt{2^{2}*2^{2}*3} - \sqrt{3^{2}*2*11} \\\\5\sqrt{3} +\frac{1}{2} *4 \sqrt{3} - 3 \sqrt{2*11} \\\\5\sqrt{3} +2 \sqrt{3} - 3 \sqrt{22} \\\\5*1.732 +2*1.732 - 3 \sqrt{22} \\\\8.66 + 3.464 - 3 \sqrt{22}\\\\12.124- 3 \sqrt{22}
