Oduvanchick [21]3 years ago
4 0

Answer:

Step-by-step explanation:

Thrice the sum of three fifths and two thirds less one half  is expressed as 3(3/5 + 2/3)-1/2

Open the parenthesis

3(3/5) + 3(2/3) - 1/2

= 9/5 + 6/3 - 1/2

Find LCM

= 9(6)+10(6)-15/30

= 54+60-15/30

= 54+45/30

= 99/30

= 3 9/30

= 3 3/10

Hence the number id 3 3/10

Answer:

Your answer would be B: 30 ft squared

Step-by-step explanation:

Find the area of the circle: 5.5 (radius) multiply it by itself then multiply that by 3.14 which gets you 94.985. Now find the area of the square which is 8*8 = 64. Subtract 64 from 94.985 and your answer will be 30.985. The questions asks for the approximate (estimate), so the closest one would be 30 ft squared

What is 65.047 to 1 decimal place?
Anarel [89]
65.0

This is because 4 is not a big enough number to round up, so you must round down. When it is 5 and over, you can round up.

Convergent or divergent?
navik [9.2K]

Answer:

Convergent

Step-by-step explanation:

This is an alternating series where bn = 2n / eⁿ.  Apply the alternating series test:

lim(n→∞) bn

= lim(n→∞) (2n / eⁿ)

Use L'hopital's rule:

= lim(n→∞) (2 / eⁿ)

= 0

For n ≥ 1, the series is decreasing. 2(n+1) / eⁿ⁺¹ < 2n / eⁿ.

Therefore, the series converges.
