Solve for X <br><br>Explain if possible :)

The two labeled angles are alternate interior angles, and as such, they are the same.

From this result you can build the equation

15x-2 = 13x+2

and solve it for x: subtract 13x from both sides to get

2x-2=2

and add 2 to both sides to get

2x = 4 \implies x = 2

Check: if we plug the value we found we have

13\cdot 2 + 2 = 26+2 = 28 = 15\cdot 2 - 2 = 30-2

So the angles are actually the same, as requested.

Fill 350 milliliter bottles from a 30 liter drum how many bottles
Mama L [17]

Answer:

  85

Step-by-step explanation:

0.350 L × n = 30 L . . . . . where n is the number of bottles.

Divide by 0.350:

  n = (30 L)/(0.350 L) ≈ 85.7

85 bottles can be filled, and one can be partially filled.

_____

Of course, you know the SI prefix milli- means 1/1000, so 350 mL = 350/1000 L = 0.350 L. When you do the division indicated above, ...

  (30 L)/(0.350 L)

the units of liters cancel, and you are left with the number of bottles.

Kisachek [45]

Answer:

See possible solutions below.

Step-by-step explanation:

The statements are not given. But the following can be determined from the graph:

  • More days recorded temperatures between 82 and 84 then other temperatures.
  • The least number of days recorded temperatures between 88 and 90.
  • The histogram is skewed to the right also known as positive skewed distribution.
  • The mean and median will most likely be in the range of 82-84 temperatures. But the mean will be greater than the median.
