Find the common difference of the arithmetic sequence -5, -14, -23, ...
BartSMP [9]

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>

:\implies -5 , -14 , -23

<u>Common</u><u> difference</u><u> </u><u>:</u><u>-</u><u> </u>

:\implies CD = -14 -(-5) = -14+5=-9

:\implies 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>

Write 3.617 correct to 2 decimal places
astra-53 [7]
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 .

1) A company makes boxes of crackers that should weigh 213g. A
Lesechka [4]

The boxes can weight at most 5 grams less than the desired amount, so they can't be lighter than

213-5=208 grams

Similary, they can't weight more than 5 grams more than the desired amount, so they can't be heavier than

213+5=218 grams

So, the acceptable range is between 208 and 218.

PLEASE HELP The measure of an angle is eight times the measure of its complementary angle. What is the measure of each angle?
sveta [45]
  • Answer:

<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>
