Step-by-step explanation:
Answer:
-11/64
Step-by-step explanation:
Answer:
Note: The expression "h =300- pi r /pi r" would equate to 299, as written. I find h = (300 - π
)/πr to be the equation for height.
Step-by-step explanation:
The total surface area of a sylinder is 2πr(h+r) where h is the height and r is the radius. That consists of top and bottom disks, each with an area of π
, for a total of 2π
. The side is a continous sheet that has an area of 2πrh, where h is the height. 2πr is the circumference of the can, so the surface area of the side is 2πrh.
The total surace area of a closed cylinder is therefore 2π
+ 2πrh.
2π
+ 2πrh = 600
π
+ πrh = 300
πrh = 300 - π
h = (300 - π
)/πr
Answer:
types of reading instruction - independent variable
reading comprehension of students - dependent variable
Explanation:
When it comes to the "experimentation" of a study, there are factors or variables that are being considered. These are <em>"independent variable</em>" and <em>"dependent variable."</em>
Independent variable refers to the variable that is being controlled. This affects the dependent variable. The influence of the independent variable on the dependent variable is <u>very important.</u>
So, in the situation above, the independent variable is the "types of reading instruction for a school year" while the dependent variable is the "reading comprehension" of the students.
<em>This means that the reading comprehension of the students will largely depend on the types of reading material.</em>
Thus, this explains the answer.
-8x+18y=-12
24x-18y=18
16x=6
X=3/8
Y=3-12)/6
y=-3/2
