A surface amount of mass in a certain volume amount of matter an object contains.
I believe the second sentence is the answer since density is the measurement that compares the amount of matter that an object has to its volume.
Given :
Nathan smiled at 50 people one day and recorded that 36 people smiled back at him.
To Find :
How many people should Nathan expect to return a smile if he smiles at 650 people over a period of time.
Solution :
Ratio of people smiled by total number of people is :
Now, it is given that we have to use the given conditions.
Therefore, ratio will be same :
Therefore, number of smiles Nathan expect to return is 468.
33 rounded to the tens place would be 30.
89 rounded to the tens place would be 90.
Answer:
296
Step-by-step explanation:
74+68+79+75
=142+79+75
=221+75
(1) QS bisecting <PQR implies <PQS = <SQR
(2) <PQS=45 deg and (1) imply <SQR also = 45 deg
(3) from (2) it follows that <PQR = <PQS + <SQR = 45 + 45 deg = 90 deg and therefore the triangle is right-angled
