EXPLANATION
If the first two terms of an arithmetic sequence are 7 and 4, then we know that an arithmetic sequence has a constant difference d and is defined by

Check wheter the difference is constant:
Compute the differences of all the adjacent terms:

Replacing terms:
4-7 = -3
The difference between all of the adjacent terms is the same and equal to
d = -3
The first element of the sequence is


Therefore, the nth term is computed by
d= -3

Refine
d= -3 ,

Now, replacing n=7

So, the answer is -11.
Solve:-
2.39 = decimal
2.39 × 100 = 239
239%
2.39 = C. 239%
Answer:

Step-by-step explanation:
The measure of arc which the right triange cuts from the circle is
this means the central angle has the same measure.
Angle with measure
is inscribed angle subtended on the given arc. Its measure is half the measure of the central angle, hence

Angles with measures
and
are complementary angles (add up to 90°), so

Answer:
A book about a mass of 1 kilogram, but that isn't the only answer.
Explanation:
There's many objects with a mass of one kilogram like one liter of water, a pineapple, bag of sugar etc.
