a bus travels 18 miles in 15 minutes at the same rate what distance will the bus travel in 50 minutes

1 answer:

7 0

So the roc(rate of change) here would be 18/15 which simplifies to 1.2 and then just mutiply this by 50 to get...
60 miles

An investigator purchased 150 shares of stocks at $12.60 per share, and sold the shares later for $11.94 per share. Calculate th

ziro4ka [17]

Given Information:

Number of shares = 150

Buying rate = $12.60 per share

Selling rate = $11.94 per share

Required Information:

Profit or loss = ?

Answer:

Loss = $99

Step-by-step explanation:

The total purchasing cost of the shares is

C = Number of shares*Buying rate

C = 150*$12.60

C = $1890

The total selling cost of the shares is

S = Number of shares*Selling rate

S = 150*$11.94

S = $1791

Profit or loss = Selling cost - Buying cost

Profit or loss = $1791 - $1890

Profit or loss = -$99

Therefore, the investigator has incurred a loss of $99 by this transaction.

The volume of a cone is 36 pi inches cubed. What is the volume of a cylinder with the same base and height as the cone?

Roman55 [17]

Answer:

3*36=108 pi

Step-by-step explanation:

V_cone = 1/3 pi * r^2 * h

V_cylinder = pi*r^2*h

If you multiply the cone's volume by 3 then you get the cylinder's volume. They become the same formula

3 V_cone = pi r^2 h

Since the cone's volume is 36pi They cylinder's volume is 3*36pi = 108 pi

If √3 = 1.732, then √[(√3-1)/(√3+1)] is equal to

adelina 88 [10]

Step-by-step explanation:

<h3><u>Given Question :-</u></h3>

$\sf \: \sqrt{3} = 1.732, \: then \: \sqrt{\dfrac{ \sqrt{3} - 1}{ \sqrt{3} + 1} }$

$\red{\large\underline{\sf{Solution-}}}$

Given expression is

$\rm :\longmapsto\: \sqrt{\dfrac{ \sqrt{3} - 1}{ \sqrt{3} + 1} }$

<em>On rationalizing the denominator, we get </em>

$\rm \: = \: \sqrt{\dfrac{ \sqrt{3} - 1}{ \sqrt{3} + 1} \times \dfrac{ \sqrt{3} - 1}{ \sqrt{3} - 1} }$

$\rm \: = \: \sqrt{\dfrac{ {( \sqrt{3} - 1)}^{2} }{( \sqrt{3} + 1)( \sqrt{3} - 1)} }$

$\boxed{ \tt \: (x - y)(x + y) = {x}^{2} - {y}^{2} \: }$

<em>So, using this, we get </em>

$\rm \: = \: \dfrac{ \sqrt{3} - 1}{ \sqrt{ {( \sqrt{3})}^{2} - {(1)}^{2} } }$

$\rm \: = \: \dfrac{ \sqrt{3} - 1}{ \sqrt{ 3 - 1} }$

$\rm \: = \: \dfrac{ \sqrt{3} - 1}{ \sqrt{2} }$

$\rm \: = \: \dfrac{ \sqrt{3} - 1}{ \sqrt{2} } \times \dfrac{ \sqrt{2} }{ \sqrt{2} }$

$\rm \: = \: \dfrac{(1.732 - 1) \sqrt{2} }{2}$

$\rm \: = \: \dfrac{0.732 \times \sqrt{2} }{2}$

$\rm \: = \: 0.366 \sqrt{2}$

Hence,

$\rm :\longmapsto\: \boxed{ \rm{ \: \: \: \sqrt{\dfrac{ \sqrt{3} - 1}{ \sqrt{3} + 1} } = 0.366 \sqrt{2} \: \: \: }}$

<h2>More Identities to know :- </h2>

(a + b)² = a² + 2ab + b²

(a - b)² = a² - 2ab + b²

a² - b² = (a + b)(a - b)

(a + b)² = (a - b)² + 4ab

(a - b)² = (a + b)² - 4ab

(a + b)² + (a - b)² = 2(a² + b²)

(a + b)³ = a³ + b³ + 3ab(a + b)

(a - b)³ = a³ - b³ - 3ab(a - b)
