Answer:

30 hrs

Step-by-step explanation:

Downstream. In water, the direction along the stream is called downstream.

Upstream. In water, the direction against the stream is called upstream. Let the speed of a boat in still water be u km/hr and the speed of the stream be v km/hr, then. Speed downstream = (u + v) km/hr. Speed upstream = (u - v) km/hr

Drag a statement or reason to each box to complete this proof.
Pepsi [2]

In the given quadrilateral ABCD,

m\angle A=7x^{\circ} , m\angle B=5x^{\circ}, m\angle C=7x^{\circ} , m\angle D=5x^{\circ}  (Given)

m\angle A + m\angle B+ m\angle C+ m\angle D=360^{\circ}

(Sum of interior angles of a quadrilateral is 360 degrees)

7x\dot{^{\circ}} + 5x^{\circ}+ 7x\dot{^{\circ}} + 5x^{\circ}=360^{\circ}(Substitution Property)

24x^{\circ}=360\dot{^{\circ}} (Addition Property of Equality)

x=15^{\circ}

Find the 100th term to 1,3,9,27​
shusha [124]

Answer:

The n-th term of this sequence appears to be

3

n

−

1

,

n

≥

1

.

Step-by-step explanation:

These are powers of

3

ordered from

3

0

=

1

to

3

a

(for an integer

a

≥

1

). However, the first convenient value for

n

is

1

, not

0

(imagine saying the 0th term of a sequence). Because of that, since the first term is actually

3

0

, we need to start from the first term (

n

=

1

) being

3

1

−

1

. The next is

3

2

−

1

,

3

3

−

1

...

3

n

−

1

.
