Rationalize the denominator and simplify 6/√2-√3
Answer:
Step-by-step explanation:
[tex]\frac{6}{\sqrt{2} - \sqrt{3} } * \frac{\sqrt{2} + \sqrt{3} }{\sqrt{2} + \sqrt{3} }[/tex]
[tex]\frac{6\sqrt{2} + 6\sqrt{3} }{2-3}[/tex]
[tex]-6(\sqrt{2} + \sqrt{3} )[/tex]
The fraction after rationalizing the denominator is given by the equation
A = -6 ( √2 + √3 )
What is a Fraction?An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a proper fraction is less than the denominator.
Given data ,
Let the fraction be represented as A
Now , the value of A is
A = 6 / ( √2 - √ 3 ) be equation (1)
Now , on simplifying the equation , we get
To rationalize the denominator of the fraction ,
Multiply the denominator by its conjugate ,
So , the conjugate of ( √2 - √ 3 ) = ( √2 + √ 3 )
Multiplying the numerator and denominator of the fraction by ( √2 + √ 3 )
A x ( √2 + √ 3 ) / ( √2 + √ 3 )
Substituting the values in the equation , we get
[ 6 / ( √2 - √ 3 ) ] x ( √2 + √ 3 ) / ( √2 + √ 3 )
On simplifying the equation , we get
6 ( √2 + √ 3 ) / ( 2² - 3² )
So , the value of A is A = 6 ( √2 + √ 3 ) / ( -1 )
A = -6 ( √2 + √ 3 )
Therefore , the value of A is A = -6 ( √2 + √ 3 )
Hence , the equation A = -6 ( √2 + √ 3 )

can someone explain this to me?? so im trying to find the scale factor of quadrilateral I to quadrilateral II and the answer is 1/2 but how does that make sense if quadrilateral I is smaller than Quad II? if we were to use the scale factor wouldnt it just divide our side lengths in half?
Answer:
the scale factor is 1/2 you are right and that is credible as the larger cd is 20 and smaller bc 10 which make out that it is half of the other Quad and the marking on the edge makes clear us that it is equal whatever the drawing is.
Step-by-step explanation:
BC=2CD
10x=20
x=10/20
x=1/2
if u want to find the other angle then it is 2 times of the smaller quad that will be:
AG=FE
15=2(15)=30
AB=ED
9=2(9)=18
GC=FC
13=2(13)=26

The radius of a circle is 40 miles. What is the angle measure of an arc 9pi miles long?
Answer:
40.5°
Step-by-step explanation:
So this problem is a ratio setup. First, you have to calculate the total circumference of the circle using the following formula:
c = 2πr
Where c is the circumference, and r is the radius of the circle. Therefore:
c = 2π(40)
Simplify:
c = 80π
Now if the arc is 9π miles long, then it's a fraction of the whole circle, which is 360° . We can set this up as follows:
[tex]\frac{9\pi }{80\pi }[/tex] = [tex]\frac{x}{360}[/tex]
Now if we cross-multiply to solve for x:
(9)(π)(360) = (80)(π)(x)
When simplified dividing by 10π :
9*36 = 8x
Simplfy.
324 = 8x
Solve for x.
x = 40.5
This table shows direct variation. Find k.
Answer:
k=2/3
Step-by-step explanation:
As said, this table shows direct variation. The equation is y=kx.
we can solve the equation to isolate the variable to see what the equation is to find k.
divide by x on both sides
y/x=k
that means that k is y/x
so we can divide 2/3 for example. Or 4/6 and see it simplifies to 2/3. You can do this for the other numbers to see that they are all equal to 2/3
That means that k is 2/3

Answer:
x=12 Proportion should be 1 2/3
Step-by-step explanation:
To find PT, subtract 26 from 65= 39
26/39 is equal to 2/3, so 30/(4x-3) should also be equal to 2/3
30/(4x-3)=2/3 (Cross Multiply)
30*3=90
2(4x-3)=8x-6
8x-6=90 (Add 6 to both sides)
8x=96 (Divide 8 from both sides)
x=12

Two trains leave the station at the same time, one heading east and the other west. The eastbound train travels at 75 miles per hour. The westbound train travels at 85 miles per hour. How long will it take for the two trains to be 384 miles apart?
Do not do any rounding.
Let the time = x
Distance = Speed x time
One train is 75x, the other train 85x
Add together to equal total distance:
75x + 85x = 384
Simplify:
160x = 384
Divide both sides by 160:
x = 384 / 160
x = 2.4 hours

Examples: Rain, Snow, Hail, Sleet
Evaporation:
The process of a liquid changing into gas due to an increase of tempurature or pressure.
Transpiration:
Plants absorb water through their roots and then give off water vapor through their leaves.
Accumulation:
Water collects in rivers, lakes, oceans, and other bodies of water or as ice caps or glaciers.
Infiltration:
Water soaks into the soil (not sure abt this one) from the ground level and moves into rocks through cracks and pores.
Surface run off:
Precipitation that reaches the Earths surface, flows over land, and reaches lakes, rivers, and oceans
Condensation:
The process of a gas changing into a liquid due to a decrease in temperature or pressure.
Sublimation:
The process of snow and ice changing into water vapor without first melting into water
