Answer:

B . \frac{3 n}{n+3}

Step-by-step explanation:

<u>Arithmetic sequence</u>:-

Step1:

Given sequence is \frac{3}{4} ,\frac{6}{5} ,\frac{9}{6} ,\frac{12}{7} ,\frac{15}{8}

Above sequence taking numerator terms

3,6,9,12,15 are in arithmetic progression

First term a= 3 and difference d = 3

now n t h term of given sequence is

t_{n} =a+(n-1)d

now substitute a =3 and d=3

t_{n} = 3+(n-1)3 = 3+3 n-3=3n

Step2:-

Above sequence taking denominator

4,5,6,7,8...

here a=4 and d=1

t_{n} =a+(n-1)d

t_{n} =4+(n-1)1

t_{n}=3+n

Final answer is the general term of given sequence is

t_{n} = \frac{3n}{3+n}

Sam is delivering two refrigerators that each weigh 105 kilograms there is an elevator with a weight limit of 1,00 pounds
rosijanka [135]

Question:

Sam is delivering two refrigerators that each weigh 105 kilograms. There is an

elevator with a weight limit of 1,000 pounds. Can he take both refrigerators on the

elevator in one trip? (1 kilogram 2.2 pounds)

Answer: yes he can

Step-by-step explanation:

Yes he can.

He can if the total weight of the 2 refrigerator didn't exceed the weight limit of the elevator.

Therefore:

Since 1 refrigerator weigh 105kg

2 refrigerator = 2 x 105kg = 210kg

The weight limit of the elevator 1000pounds convert to kg.

Since

2.2 pounds = 1kg

1000 pounds = 1000/2.2 kg

=454.55kg

Weight limit of the elevator = 454.55kg.

Since Weight of the 2 refrigerator is less than

weight limit of the elevator, he can take both refrigerators on the elevator in one trip
