1 answer:
serious [3.7K]2 years ago
6 0

Step-by-step explanation:

=  \frac{2 \sqrt{2}   -  \sqrt{3} }{ \sqrt{2} +  \sqrt{3}  }

=  \frac{2 \sqrt{2} -  \sqrt{3}  }{ \sqrt{2} +  \sqrt{3}  }  \times  \frac{ \sqrt{2} -  \sqrt{3}  }{ \sqrt{2} -  \sqrt{3}  }

= \frac{ 2( \sqrt{2}  -  \sqrt{3} )( \sqrt{2}  -  \sqrt{3} )}{ { \sqrt{2} }^{2} -  { \sqrt{3} }^{2}  }

=  \frac{2(2 -  \sqrt{6}  -  \sqrt{6} - 3) }{2 - 3}

=  \frac{2( - 1 - 2 \sqrt{6} )}{ - 1}

=  \frac{ - 2(1 + 2 \sqrt{6} )}{ - 1}

= 2(1 + 2 \sqrt{6} )

= 2 + 4 \sqrt{6}

I'm going to suppose that this is asking for the volume.
The formula to find volume for a cylinder is<span> V= pi r 2(squared) h
</span><span><span />The radius is 10cm and the height is 14cm
Then plug the numbers in
So you should get V=3.14 x 10(squared) x 14
The once you multiply all that you should get 4396 cm(cubed)

HELP ME PLEASE!! ASAP!!
Levart [38]
The total area is given by:
 A1 = (300) * (500)
 A1 = 150000 feet ^ 2
 The area occupied by 5 people is:
 A2 = (5) * (5)
 A2 = 25 feet ^ 2
 Then, we can make the following rule of three:
 5 --------> 25
 x --------> 150000
 Clearing x we have:
 x = (150000/25) * (5)
 x = 30000

Courtney must earn at least $150 to pay for broken window. She earns $10 for every car she washes.
valkas [14]

Answer:

10c ≥ 150

At least 15 cars (or c ≥ 15)

Step-by-step explanation:

If she gets $10 for every car she washes a car then 10c is the rate of her gaining money and she needs at least (greater than or equal to) $150.

This equation can be used to express the situation:

10c ≥ 150

<em>To solve you divide the 10 from both sides of the inequality to get.</em>

c ≥ 15
