Step-by-step explanation: Lets estimate first to the nearest whole number.
15.8 kilograms estimated is 16 kg
17.42 kilograms estimated is 17 kg
16.28 kilograms estimated is 16 kg
Now add the estimated values, 16 + 17 + 16 = 49 kg
The estimate gives you the correct answer because it gives you an accurate reasonable amount in this problem.
I'm guessing S^20 is actually referring to the 20th partial sum
, with
in the arithmetic case, and
in the geometric case.
(a) Combining like terms, we have
and invoking the formula
we end up with
(b) Multiply
by 1.1, then subtract this from
:
10.5 or 10 1/2 basically ten and a half
Answer: OPTION C.
Step-by-step explanation:
1. To solve this problem you must apply the Pythagorean Theorem, which is shown below:
Where a is the hypotenuse, and b and c are the legs of the triangle.
2. When you solve for one of the legs and substitute values, you obtain that the result is:
Answer:
Step-by-step explanation:
4x-8<5x+4
4x<5x+12
-x<12
flip sign
x > -12
