The greatest common factor (GCF) of 21 and 84 is 21.
The GCF is the largest number by which both numbers can be divided. Between 21 and 84, it is 21 because 21/21=1 and 84/21=4.
Answer:
The cost of a pound of rice = $0.48
Step-by-step explanation:
The cost of rice is $1.05 per kilogram.
1 kilogram = 2.2 pounds
To find the cost of rice per pound, we need to divide.
Divide the cost of rice per kilogram by 2.2, we get
The cost of a pound of rice = 1.05/2.2
=$0.48
Hope this will help you.
Thank you.

Answer: The measures of all the three angles are 24 , 60 and 96
Step-by-step explanation:
Since the measures are given in ratio form, the first thing is to find the total ratio, which is
2 + 5+ 8 = 15
Recall that the sum of angles in a triangle is 180 ,so to calculate each angle , we have
2/15 x 180 = 24
also , 5/ 15 x 180 = 60
Finally, 8/15 x 180 = 96
The triangle is obtuse , since it is having one angle greater than 90.
It can not be acute because of the existence of 96 , for a triangle to be acute , all the angles must be less than 90 , and it can not be right triangle because there is no existence of 90
