Hi there! The answer to this problem is 27.

n=27.

Well this is simply subtraction so just add the other two number to find the answer.

22 add 5 would be 27 so 27 would be the answer or can say n.

n-5=22

5+n=22

22+5=n

n=27

Answer:

<em>D.1767.1 in³</em>

Step-by-step explanation:

<em>volume of a sphere=4/3πr³</em>

<em>where r=radius of the sphere</em>

<em>Given diemeter= 15in</em>

<em>so radius=15/2=7.5in</em>

<em>volume=4/3×π×(7.5)³</em>

<em>=4/3×22/7×(7.5)³</em>

<em>=1767.1in³</em>

<em>hope it helps...</em>

<em>have a great day!!</em>

A boat crew rowed 10.5 miles downstream, with the current, in 1.5 hours. the return trip upstream , against the current , covere
alukav5142 [94]

Answer:

The speed of the boat is 5 miles per hours

The speed of the current is 2 miles per hours .

Step-by-step explanation:

Given as :

The distance cover by boat downstream = D = 10.5 miles

The time taken by boat to cover D distance = T = 1.5 hours

The distance cover by boat Upstream = d = 10.5 miles

The time taken by boat to cover d distance = t = 3.5 hours

Let The speed of boat =  x mph

Let The speed of current =  mph

Now, According to question

∵ Speed = \dfrac{Distance}{Time}

<u>For Downstream</u>

x + y = \dfrac{D}{T}

Or, x + y =  \dfrac{10.5}{1.5}

Or, x + y = 7          .......A

<u>For Upstream</u>

x - y = \dfrac{d}{t}

Or, x - y =  \dfrac{10.5}{3.5}

Or, x - y = 3          .......B

Now, Solving eq A and eq B

So, (x + y) + (x - y) = 7 + 3

Or, (x + x) + (y - y) = 10

Or, 2 x + 0 = 10

∴  x = \dfrac{10}{2}

i.e x = 5 mph

So, The speed of the boat = x = 5 miles per hours

Put the value of x into eq A

∵ x + y = 7

Or, 5 + y = 7

∴ y = 7 - 5

i.e y = 2 mph

So, The speed of the current = y = 2 miles per hours

Hence, The speed of the boat is 5 miles per hours and The speed of the current is 2 miles per hours . Answer
