Answer:

Time taken by the un powered raft to cover this distance is T = 192.12 hr

Step-by-step explanation:

Let speed of boat = u

Speed of current = v

Let distance between A & B = 100 km

Time taken in downstream = 32 hours

u + v = 3.125 ------ (1)

Time taken in upstream = 48 hours

u - v = 2.084 ------- (2)

By solving equation (1) & (2)

u = 2.6045

v = 0.5205

Now the time taken by the un powered raft to cover this distance

Because un powered raft travel with the speed of the current.

T = 192.12 hr

Therefore the  time taken by the un powered raft to cover this distance is

T = 192.12 hr

kompoz [17]

Answer: 34

Step-by-step explanation:

<u>Given expression</u>

[3 - (3 · 3) + 33 ÷ 3] × 4 · 5 / 10 - 2 · 3

<u>Simplify by parentheses in the bracket</u>

=[3 - 9 + 33 ÷ 3] × 4 · 5 / 10 - 2 · 3

<u>Simplify by multiplication</u>

=[3 - 9 + 33 ÷ 3] × 20 / 10 - 6

<u>Simplify by division</u>

=[3 - 9 + 11] × 10 - 6

<u>Simplify by bracket (addition/subtraction)</u>

=[-6 + 11] × 10 - 6

=[4] × 10 - 6

<u>Simplify by multiplication</u>

=40 - 6

<u>Simplify by subtraction</u>

=\boxed{34}

Which of the following are geometric series?
Temka [501]

Answer:

-256 +64 - 16 + 4 - 1

Step-by-step explanation:

A series is the summation of all the terms in a sequence.

So it is only the last three options that qualify to be a series.

The series 2 +5 + 8 + 11 + 14 + 17 has no common ratio. It is not geometric.

The series 1+1+2+3+5+ 8 +13 +21 also has no common ratio. It is not geometric.

The series -256 +64 - 16 + 4 - 1 has a common ratio of

r=\frac{64}{-256}=-\frac{1}{4}

There the only series that is geometric is.

-256 +64 - 16 + 4 - 1
