The angle 181 degrees is in quadrant 3 (Q3) since it is between 180 and 270. We can rule out choice A as we want angles that aren't in Q3

-179 is coterminal to 181 since 360+(-179) = 181. Which is identical to choice A. We can rule this choice out too. To find coterminal angles, you add or subtract 360

145 is NOT in Q3 since it is not between 180 and 270. So this is the answer

-97 is coterminal to 263 (360+(-97) = 263), so this is in Q3. We can cross choice D off the list

Answer: Choice C) 145 degrees

A fruit seller has 3 crates of apples. Each crate has 100 apples. If he packed 6 apples in 1 box. Which of these gives the numbe

xz_007 [3.2K]

Answer:

300 divided by 6

Step-by-step explanation:

Given that;

Number of crates of apple owned by fruit seller = 3 crates

Number of apples in each crate = 100 apples

He packed 6 apples in 1 box;

Unknown:

Number of boxes needed to pack all the apples = ?

This problem is pretty straight forward;

Number boxes needed to pack all apples = $\frac{Number of crates owned by fruit seller x number of apples per crate}{Number of apples per box}$

Input the parameters and solve;

Number of boxes need to pack all apples = $\frac{100 x 3}{6}$ = $\frac{300}{6}$

So the solution is 300 divided by 6

Find the slope of a line that passes through the given points. Write your answer below.

12345 [234]

Just use the formula:
$slope(m) = \frac{y_2-y_1}{x_2-x_1}$

Then, plug in numbers:
$m = \frac{1-4}{-2-3} = \frac{-3}{-5} = \frac{3}{5}$

And that would be your answer: 3/5 is the slope.
