Answer:
-9
Step-by-step explanation:
<u>Given </u><u>:</u><u>-</u><u> </u>
- A Arithmetic sequence -5 , -14 , -23 ...
And we need to find out the common difference of the Arithmetic sequence . The common difference of a Arithmetic sequence is the number which is added to a term to obtain the next term of the sequence . And it can be obtained by subtracting the consecutive terms.
<u>Sequence</u><u> </u><u>:</u><u>-</u><u> </u>
-5 , -14 , -23
<u>Common</u><u> difference</u><u> </u><u>:</u><u>-</u><u> </u>
CD = -14 -(-5) = -14+5=-9
CD = -23-(-14) = -23+14=-9
<u>Hence </u><u>the</u><u> </u><u>common</u><u> difference</u><u> </u><u>is </u><u>(</u><u>-</u><u>9</u><u>)</u><u> </u><u>.</u>
We don't know what's correct, because we don't know anything about where the number came from. If you want the number ROUNDED to two places, that's 3.62 If you want it TRUNCATED (shortened, trimmed) to two places, that's 3.61 .
The boxes can weight at most 5 grams less than the desired amount, so they can't be lighter than
grams
Similary, they can't weight more than 5 grams more than the desired amount, so they can't be heavier than
grams
So, the acceptable range is between 208 and 218.
<em>A = 80°</em>
<em>B = 10°</em>
- Step-by-step explanation:
<em>complementary angle => </em>
<em>=> A + B = 90°</em>
<em>A = 8B</em>
<em />
<em>8B + B = 90°</em>
<em>9B = 90°</em>
<em>B = 90° : 9</em>
<em>B = 10°</em>
<em>A = 8B</em>
<em>A = 8×10°</em>
<em>A = 80°</em>
Answer:
total amount paid = 32.5 + 28.9 + 24.95 = 86.35
20% of the total amount paid = 0.2 * 86.35 = 17.27
you tip 17.25$
