Answer:

distribute the radicals, simplify the radicals, combine like terms

Step-by-step explanation:

(-5sqrt[2]-sqrt[6])(sqrt[3]+2sqrt[2])

(-5\sqrt{2})-\sqrt{6} )(\sqrt{3} +2\sqrt{2} )

To multiply it , we apply FOIL method

Distribute the radicals inside the second parenthesis

After distributing the radicals inside the second parenthesis we multiply and simplify the radical as much as we can

Then we combine like terms to simplify further

distribute the radicals, simplify the radicals, combine like terms

Find the percent of change. Round to the nearest percent.
katovenus [111]

Answer:

<u> -54.5%</u>

Step-by-step explanation:

You will have to use this formula

\frac{new value-oldvalue}{oldvalue}

When substituted in you have \frac{30-66}{66}

30-66=-36

-36/66= -0.54 (54 repeating)

Then you have to convert this into a percentage, -54.54(repeating) percent

To the nearest hundredth you would round down to<u> -54.5%</u>.

It is a Decrease because it is negatated.

And model links of 12 cm represents an actual length of 102 feet what is the scale for the model
babymother [125]
If there are 30.48cm in a foot and 12cm represents 102 feet then 12 cm represents 3109cm or 12:3109. Divide both sides by 12 to get the scale and it is: 1:259, the scale is 259.

Hope this helps :)

50 POINTS PLEASE HELP
lorasvet [3.4K]

Answer:

perimeter= 5\sqrt{15} + 5\sqrt{5}

Step-by-step explanation:

Given ,

A right angle triangle ΔABC with right angle at C and ∠A=30° and AC=5√5 units .

Let ∠A=A,∠B=B∠C=C and AC=b,BC=a,CA=b .

Implies perimeter of triangle = a+b+c .

now

tanA=\frac{a}{b} \\\a=b*tanA\\a= 5\sqrt{5} *tan30^0\\a=\frac{5\sqrt{5}}{\sqrt{3}}

and

cosA=\frac{b}{c} \\\c=\frac{b}{cosA} \\c=\frac{10\sqrt{5}}{\sqrt{3} }

implies ,

perimeter = \frac{5\sqrt{5}}{\sqrt{3}} + 5\sqrt{5} +\frac{10\sqrt{5}}{\sqrt{3} }\\perimeter= 5\sqrt{15} + 5\sqrt{5}
