1/2 because there are 3 odd numbers on a number cube and 6 numbers in total and 3/6 simplified is 1/2

Answer:

I just answered this question, In case you missed it, here it goes again:

Values for the coefficient in the product k:

$a=b=c=d=3*10^8$ , so the first four boxes should be filled with the number "3"

Drop down arrow: "does"

Step-by-step explanation:

We perform all the products of wavelength time frequency indicated for the column of the quantity "k":

$a$ = $1 * 10^{-10} * 3\, * 10^{18} = 3 * 10^{-10+18} = 3 * 10^{8}$ =

$b=1 * 10^{-1}*3*10^9=3* 10^{-1+9}=3*10^8$

$c=600*10^{-6}*5*10^{11}=3000*10^{-6+11}=3000*10^5=3*10^3*10^5=\\=3*10^{3+5}=3*10^8$

$d=4*10^{-7}*7.5*10^{14}=30.0*10^{-7+14}=30*10^7=3*10*10^7=\\=3*10^{1+7}=3*10^8$

Therefore, all products of these different wavelengths and their associated frequencies render the exact same answer : $3*10^8$ , which means that as one of these quantities increase, the other one will decrease in the same proportion to give the same numerical answer.

This means that the two quantities are associated via inverse proportionality. As seen in the equation below, if the quantities "x" and "y" are related by inverse proportionality (shown as one equals a constant "A" divided by the other variable), their product x*y will give that constant value "A" (which in our case is $3*10^8$ .

$x=\frac{A}{y} \\x*y=A$

Paul has completed 140 laps so far this season. He completes an additional 12 laps during each practice. Jacklyn has completed 5

kakasveta [241]

Paul: 140 + 12x

Jacklyn: 56 + 16x

Where x is how many practice sessions he had this season

"After how many more practices will Paul and Jacklyn have completed the same number of laps?"

This means what will x be if both equations are equal to each other

140 + 12x = 56 + 16x

Isolate x in one side by subtracting both sides by 12x

140 + 12x - 12x = 56 + 16x - 12x

140 = 56 + 4x

Subtract both sides by 56 to shift the 56 from the right side to the left side

140 - 56 = 56 - 56 + 4x

84 = 4x

Divide both sides by 4 to isolate x

84/4 = 4/4x

21 = x

x = 21

They'll have completed the same number of laps after 21 practices

Hope it helps :)

Branliest would be appreciated
