Suppose you travel to Africa and drop a note in a sealed bottle in the Nile at its source. If the bottle traveled at 7 km/h on a
ValentinkaMS [17]

The time required for the bottle to reach the end of Nile is 963 hours

What is Speed?

Speed is defined as the rate of change of position of an object in any direction. Speed is measured as the ratio of distance to the time in which the distance was covered. Speed is a scalar quantity as it has only direction and no magnitude

Speed = Distance / Time

Given data ,

Let the speed of the bottle in the river be S = 7 km/h

Let the distance traveled by the bottle in the river be D = 6741 km

Now , the time taken by the bottle to reach the distance D with speed S is calculated by the equation

Speed = Distance / Time

and ,

Time = Distance / Speed

Substituting the values of distance and speed in the equation , we get

Time taken by the bottle = 6741 / 7

                                          = 963 hours

Therefore , the time required is 963 hours

Hence , The time required for the bottle to reach the end of Nile is 963 hours

The table below shows a baseball player’s batting average batting left and right versus left- and right-handed pitches Left-hand
Assoli18 [71]

Answer:

C. 11 is the correct answer

Step-by-step explanation:

The table representing the probabilities of player's batting average is,

                        Left-Handed pitchers         Right-Handed pitchers

Bats Left                    0.285                                      0.175

Bats Right                   0.215                                      0.250

So, when the players bats left 100 times,

The probability of hits he gets when faced by left-handed pitchers = 0.285 × 100 = 28.5

The probability of hits he gets when faced by right-handed pitchers = 0.175 × 100 = 17.5

Thus, the difference in the hits = 28.5 - 17.5 = 11

Hence, the player will get 11 more hits t when he faces left-handed pitchers as opposed to right-handed pitchers.

melamori03 [73]

Answer:

The scale factor is 18 to 1 for the painting

Step-by-step explanation:

Here we want to get the scale factor of the original to what is reproduced

Let us have same units first

Mathematically;

1 foot = 12 inches

3 feet = 36 inches

2 feet = 24 inches

So 36 to 2 and 24 to 1 1/3

That will be ratio 36/2 = 18 to 1

same as 25 divided by 1 1/3 = 18 to 1
