A paddleboat can move at a speed of 4 ​km/h in still water. The boat is paddled 12 km downstream in a river in the same time it
Bas_tet [7]

Answer:

Speed of the river = \frac{4}{3} km per hour

Step-by-step explanation:

Speed of the boat in still water = 4 km per hour

Let the speed of the river = v km per hour

Speed of the boat upstream = (4 - v) km per hour

Time taken to cover 6 km = \frac{\text{Distance}}{\text{Speed}}

                                           = \frac{6}{4-v} hours

Speed of the boat downstream = (4 + v) km per hour

Time taken to cover 12 km = \frac{12}{4+v} hours

Since, time taken by the boat in both the cases is same,

\frac{6}{4-v}= \frac{12}{4+v}

6(4 + v) = 12(4 - v)

24 + 6v = 48 - 12v

12v + 6v = 48 - 24

18v = 24

v = \frac{24}{18}

v = \frac{4}{3} km per hour

Pls help me this is due tomorrow

Step-by-step explanation:

Claim: There's 14 Goats and 9 Chickens!!

Data:

Working with the Provided Information.

Let the Number of goats be x

let the Number of Chickens be y

x + y = 23..... (i)

Since the goat Possesses Two Pair of Legs... Which is a Total of 4 Legs... We say Let its Contribution be 4x.

The Chicken has Only a Pair Of Legs...Which is a total of 2 legs.... We say let its contribution be 2y

4x + 2y = 74 .....(ii)

BRINGING BOTH EQUATIONS TOGETHER.

x + y = 23

4x + 2y = 74

From Eqn i

x= 23 - y

Substitute into eqn ii

4(23 - y ) + 2y = 74

92 - 4y + 2y = 74

92 - 2y = 74

2y = 92 - 74

2y = 18

y= 9.

Substitute y into any of the eqns to get x

x + y = 23

x + 9=23

x = 23 - 9

x = 14

This simply proves that there are 14 Goats and 9 Chickens!!!.

HAVE A GREAT DAY!

a radioactive sample contains 3.00 g of pure 11c, which has a half-life of 20.4 min. (a) how many moles of 11c are present initi
sveta [45]

The number of mole of pure 11C (carbon-11) initially present is 0.2727 mole

<h3>Description of mole </h3>

The mole of a substance is related to it's mass and molar mass according to the following equation

Mole = mass / molar mass

With the above formula, we can obtain the number of mole of pure 11C. Detail below:

<h3>How to determine the mole of 11C</h3>

From the question given, the following data were obtained:

  • Molar mass of 11C = 11 g/mol
  • Mass of 11C = 3 g
  • Mole of 11C =?

Mole = mass / molar mass

Mole = 3 / 11

Mole = 0.2727 mole

Therefore, the number of mole of pure 11C initially present is 0.2727 mole

Find the average rate of change for f(x) = x2 − 3x − 10 from x = 4 to x = 6
cluponka [151]
I believe you meant f(x) = x^2 - 3x - 10.
                                                              f(b) - f(a)
The ave. r. of c. formula is     a. r. c = -----------------
                                                                 b -a
                               (6)^2 - 3(6) - 10 - [(4)^2 - 3(4) - 10]
Here,   a. r. c. =   ------------------------------------------------------        
                                                      6-4
                                           36 - 18 -10 - 16 + 12 + 10
     ... which comes out to ---------------------------------------
                                                                2

                a. r. c. = 7             for x^2 - 3x - 10 on the interval [4,6]
