Answer:

1) 40°

2) 140°

3) 140°

5)40°

6)140°

7)140°

8)40°

Step-by-step explanation:

1 = 40 °        <em>  [Vertically Opposite angles are equal]</em>

8 = 40 °         <em>[Corresponding Angles are equal]</em>

5 = 8 = 40°  <em> [Corresponding Angles are equal]</em>

7 = 180° - 40° = 140°      <em>[Supplementary angles sum 180°]</em>

6 = 140°           <em> [Vertically Opposite angles are equal]</em>

2 = 140°            <em>[Corresponding Angles are equal]</em>

3 = 140 °          <em> [Vertically Opposite angles are equal]</em>

The initial cost to drill a well is $210000. the daily rate to operate the well is $500. The current selling price is $65 per ba
SVETLANKA909090 [29]

Hi there!

There is an initial cost of $210,000 (which you're just going to pay once)

Then it costs $500 per day to operate.

The number of days is represented by "x".


Your equation in function notation should look like this :

f(x) = 500x + 210,000


There you go! I really hope this helped, if there's anything just let me know! :)

Justin lives 3 2 5 miles from his grandfather's house. Enter the mixed number as a fraction greater than one. 3 2 5 =
elena-s [515]

Answer: \dfrac{17}{5} miles

Step-by-step explanation:

We can express a mixed fraction as an improper fraction.

The process is as follows:

a\dfrac{b}{c}=\dfrac{ac+b}{c}

The given mixed number = 3\dfrac25 miles

This can be represented as

3\dfrac25=\dfrac{3\times5+2}{5}\\\\=\dfrac{15+2}{5}\\\\=\dfrac{15+2}{5}\\\\=\dfrac{17}{5}>1

Hence, the required fraction= \dfrac{17}{5} miles
