Mathematics
1 answer:
lions [1.4K]3 years ago
3 0

Answer:

Step-by-step explanation:

angle 2 and angle 3 are linear pair

angle 1 and angle 7 are alternate exterior angle

angle 4 + angle 7=a80 degree

124 + angle 7=180

angle 7=180-124

angle 7=56 degree

angle 1 is supplementary to angle 2 ,angle 4, angle 6, angle 8 .In supplementary angle sum of two angle is always 180 degree.

angle 4 and angle 5 are supplementary angles because their sum is equal to 180 degree.

angle 4 + angle 5(being co interior angle)

3x+17+x+23=180

4x+40=180

4x=19=180-40

x=140/4

x=35

Answer:

The answer is $240

If you do one box which has 6 tiles you can get that one box has enough for 120 by 120. if you do another box you get 240 by 240 and add one more box to get 360 by 360. Unless you need to calculate for the ones she only needs and not in the box then the answer should be $240

Well, hopefully you know how to get Kelvin. For example. 1 degrees Celsius to Kelvin is 274.15.   Celsius - Kelvin 273.15. Anyway, two other related equations would be  x Celsius + 273.15 =  y (Kelvin) and   Celsius - Kelvin = Add 273.15

If the temperature in Celsius is 23 degrees, it would be 296.15 Kelvin. 

300 Kelvin is greater than 25 Celsius. I got my answer because I know to get Celsius, you would add 273.15 to the celsius. 25 + 273.15 = 298.15. So 300 Kelvin is greater than 25 Degrees Celsius.

I hope this helps!!

Professor Lauer provides a review session for half of the students (randomly determined) taking her experimental methods course.
Gnom [1K]

Answer:

Test scores

Step-by-step explanation:

In this example, there are two variables that are being analyzed: the review session that the professor is providing and the test scores of the students. The review session is the independent variable. This is because it is the variable that we can manipulate and that we have control over. On the other hand, the test scores is the variable that <em>depends</em> on whether the students received the review session or not. This makes it the dependent variable.
