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

Hope this helps!

Step-by-step explanation:

because they already have 61 dollars

Hey there!

You should not expect more than 34 times to be favorable, because favorable outcomes are about 28% of outcomes, and 28% of 100 is 28, which is less than 34.

6/21 outcomes will be favorable.

Here is a list of all possible out comes:

1 - 1

1 - 2

1 - 3

1 - 4

1 - 5

1 - 6

2 - 2

2 - 3

2 - 4

2 - 5

2 - 6

3 - 3

3 - 4

3 - 5

3 - 6

4 - 4

4 - 5

4 - 6

5 - 5

5 - 6

6 - 6

The underlined ones have one or two 3's in their outcome. There are 21 outcomes total, and 6 of them have 3's in them. We will find the percentage by doing 6/21 = .286, or 28.6%. This means that for every 100 outcomes, you should expect about 29 of them to be favorable.

I hope it helps and have an amazing day! You've got this!

Answer:

The distance of given two points

d( P₁, P₂)   [tex]= \sqrt{85}[/tex]   = 9.219

Step-by-step explanation:

Explanation:-

Given points are  p₁ ( 0,0)  and p₂ ( 7,6)

The distance formula of given points are

     d   =  [tex]\sqrt{(x_{2}-x_{1} )^{2} +(y_{2} -y_{1})^{2} }[/tex]

     d  =    [tex]\sqrt{(7-0 )^{2} +(6 -0)^{2} } = \sqrt{49 +36}[/tex]

    d = [tex]\sqrt{85}[/tex]

Precipitation:

Precipitation is condensed water vapor that falls back to earth.

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

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

The fraction after rationalizing the denominator is given by the equation

A = -6 ( √2 + √3 )

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 )
