1.

x√8 = 2

x = 2/√8 = 1/√2

so

1/√2 × √8 = 2

2.

4√x = 3

√x = 3/4

x = (3/4)^2 = 9/16

so

4√(9/16) = 3

Answer:

\large\boxed{1.\ 3}\\\boxed{2.\ 81}

Step-by-step explanation:

\sqrt[3]{a}=b\iff b^3=a\\\\\sqrt{a}=b\iff b^2=a\ for\ a,b\geq0\\==========================\\\\1.\ \sqrt[n]{8}=2\iff2^n=8\Rightarrow2^n=2^3\Rightarrow \boxed{n=3}\\\\2.\ \sqrt[4]{n}=3\iff 3^4=n\Rightarrow \boxed{n=81}

500 cats were chosen. 52% of the cats liked to sleep inside the house. Fish was the favorite dish of 25% of those cats, while 62
Alex777 [14]
You would need to take 500 * .52 = 260 next take 260 * .25 to find how many cats like fish which equals 65, the probability that it likes fish and it sleeps inside can be found by taking .52 * .25 = .13 so there would be a 13% chance of picking a cat that sleeps indoors and likes fish, 435 cats dont like fish found by taking 500-65=435 and finally to find how many cats sleep outside take 500-260=240 then take 240 * .625 = 150 then 240-150 = 90 so 90 cats like to sleep outside and like fish thats it!=) Hope this helps!

In the figure CD is the perpendicular bisector of AB . If the length of AC is 2x and the length of BC is 3x - 5 . The value of x
Dennis_Churaev [7]

Answer

Find out the value of x .

To proof

SAS congurence property

In this property two sides and one angle of the two triangles are equal.

in the Δ ADC and ΔBDC

(1) CD = CD (common side of both the triangle)

(2) ∠CDA = ∠ CDB = 90 °

( ∠CDA +∠ CDB = 180 ° (Linear pair)

as given in the diagram

∠CDA  = 90°

∠ CDB = 180 ° - 90°

∠ CDB = 90°)

(3) AD = DB (as shown in the diagram)

Δ ADC ≅ ΔBDC

by using the SAS congurence property .

AC = BC

(Corresponding sides of the congurent triangle)

As given

the length of AC is 2x and the length of BC is 3x - 5 .

2x = 3x - 5

3x -2x =5

x = 5

The value of x is 5 .

Hence proved

The rectangles in the figure below are similar. Find the value of x
V125BC [204]

Answer:

C. 6

Step-by-step explanation:

It is given that the rectangles in the figure are similar.

<em>Thus, the corresponding sides of the two rectangles will be equal.</em>

So, we get,

\frac{3}{x}=\frac{5}{x+4}

i.e. 3(x+4)=5x

i.e. 3x+12=5x

i.e. 2x=12

i.e. x = 6.

Hence, the value of x is 6.
