Answer:
Step-by-step explanation: <1= 53+47=100/2=50 degrees
<2= 180-50=130 degrees
125 inches is equal to 10 feet and 5 inches because 12 inches are in each foot. To find how many feet, you would do 125/12 which is 10 and a remainder of five. This means that 125 inches is equal to 10feet and 5 inches.
Answer: 288pi in3
Step-by-step explanation:
Volume of a sphere= 4/3pir^3
R=6inches
V=4/3pir^3
V=4/3pi(6^3)
V=4/3pi(216)
V=864pi/3
V=288pi in^3
Answer:
Internal validity
Step-by-step explanation:
The internal validity here is weak
Internal validity describes the extent to which an evidence weighs the cause and effect claim. In this study, the internal validity that brought about failure in the new exam is mainly due to the environment where the exam was written and not the new exam itself.
So this validity is weak in claiming that the new exam is not a good substitute for the old exam.
Putting them in the same good environment might help the researchers to draw a better conclusion.
Let C present amount of change
The expression is C = 50 - d
