Correct question is;

Speed of a boat in standing water is 9 kmph and the speed of the stream is 1.5 kmph. A man rows to a place at a distance of 105 km and comes back to the starting point. The total time taken by him is:

Answer:

Total time = 24 hours

Step-by-step explanation:

We are given;

Speed of a boat in standing water = 9 kmph

Speed of the stream = 1.5 kmph

Distance rowed by the man; d = 105 km

He now came back to his starting point.

Thus, we can say that;

Speed upstream; V_up = 9 - 1.5 = 7.5 kmph

Speed downstream; V_down = 9 + 1.5 = 10.5 kmph

Now, we know that;

time = distance/speed

Thus;

Total time = time taken upstream + time taken downstrem

Total time = (105/7.5) + (105/10.5)

Total time = 14 + 10

Total time = 24 hours

HELP I have attatched an image i will give extra points for best answer
Eduardwww [97]

Answer:

y = 2x

Step-by-step explanation:

Given y is directly proportional to x then the equation relating them is

y = kx ← k is the constant of proportion

To find k use the condition when x = 4, y = 8, that is

8 = 4k ( divide both sides by 4 )

2 = k, thus

y = 2x ← equation of proportion

6 numbers form an arithmetic sequence with a common difference of 4. THe sum of these numbers equals 12. What are the 6 numbers.
frutty [35]

Answer: See explanation

Step-by-step explanation:

We will use the formula for an arithmetic sequence which will be:

a + (n - 1)d

where a = unknown

n = 6

d = 4

We then slot them into the formula

a + (6 - 1)4 = 12

a + 5(4) = 12

a + 20 = 12

a = 12 - 20

a = -8

The 6 numbers are

1st term = -8

2nd term = -8 + 4 = -4

3rd term = -4 + 4 = 0

4th term = 0 + 4 = 4

5th term = 4 + 4 = 8

6th term = 8 + 4 = 12

fiona draws a 24 centimeter rectangle.gregory draws a 24 square inch rectangle.whose rectangle is in area .how do you know
Valentin [98]

Answer:

Therefore we come to a conclusion that,

Gregory's Rectangle is in Area.

Step-by-step explanation:

Given:

Fiona draws a 24 centimeter rectangle.

Gregory draws a 24 square inch rectangle.

To Find:

Whose rectangle is in area = ?

Solution:

Rectangle has a dimension as

Length and Width which are in meters, centimeters, inches, feet, units, etc.

For Area

Area\ of\ Rectangle=Length\times Width

here units are getting Multiplied so it becomes

unit × unit = unit²  = square units

m × m = m² =square meter

inch × inch = inch² =square inches

Hence Area is calculated in square units.

Therefore we come to a conclusion that,

Gregory's Rectangle is in Area.
