10x + 19.95 = 139.95

Subtract 19.95 from both sides
10x =130.00
Divide both sides by 10

X = 13

steposvetlana [31]
Even though this is not maths, let me help you. In order to answer the first question I suggest you to try to <span>imagine what would happen if people had the power to genetically alter things. It might be helpful to think about how it would affect your life. In that case you would come up to the answer on what should I do with my genetic power.
Now for the second one, let me say that </span> <span>science cannot answer because results are not in the hands of the scientists, but in the hands of the people. 
I hope this info can help</span>

1. Are there more inches in a mile or second in a day?​
Sedaia [141]

Answer:

Step-by-step explanation:

60 x 60 = 3600

3600 x 24

5280 x 12

I know for steps 2 and 3 to be equal, 3600 would have to be half of 5280 because 24 is twice 12, and it’s not. And because 3600 is more than half of 5280, I know that 3600 times 24 is more than 5280 times 12. My answer, therefore, is there are more seconds in a day.

Y is directly proportional to x^2. It is known that y=10 for a particular value of x. Find the value of y when the value of x is
Mandarinka [93]
<span>Y is directly proportional to x^2. It could be represented by the expression:

y </span>α x^2

We can make it into an equality by inserting the proportionality constant, k.

y = kx^2

k would be constant for any value of y with a corresponding value of x. We solve the problem by this concept as follows:

y1/(x1)^2 = y2/(x2)^2
10/(x1)^2 = y2/(x1/2)^2
10/4 = y2

Therefore, when the value of x is halved, y is equal to 10/4.

Static and Reasoning:
Serggg [28]

Based on the data recorded by Isabella, it can be concluded the cube is rather fair.

<h3>How many times did Isabella get each number?</h3>

Based on the data, here are the results:

  • Getting a 1: 6 times
  • Getting a 2: 5 times
  • Getting a 3: 7 times
  • Getting a 4: 5 times
  • Getting a 5: 6 times
  • Getting a 6: 7 times

This implies, in total Isabella got the same number between five and seven times. For example, the number 2 was obtained 5 times, but the number 3 was obtained 7 times.

<h3>What can be concluded based on the results?</h3>

Even though Isabella did not get the same number of times each number, the dice is rather fair because by rolling the dice thirty six times you will obtain the same number at least five times.

Moreover, there is not a big difference in the number of times you obtain each number.
