Answer:
Part A: 60
5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60.
12, 24, 36, 48, 60.
---------------------------------
Part B: 9
81 / 72 = 9
----------------------------------
Part C: 9 (8 + 9)
---------------------------------
GCF of 72 and 81 is 9...
Divide 72 by 9 and get 8.
Divide 81 by 9 and get 9.
To check multiply 9 with 8, and multiply 9 by 9.
The answer is $3,850 and have a very nice day
Answer:
see explanation
Step-by-step explanation:
Using the trigonometric identity
sin²x + cos²x = 1
Consider the left side
2cos²A - 1 ← replace 1 by sin²A + cos²A
= 2cos²A - ( sin²A + cos²A)
= 2cos²A - sin²A - cos²A
= cos²A - sin²A = right side ⇒ verified
Answer:
Answer is 25/56
Step-by-step explanation:
Given that
Katie and her brother are both writing a report. Katie write 7/8 of her report and her brother wrote 3/7 of his report
TO compare these two fractions we have to make both of them have the same denominator.
We find that as such the two fractions have denominators as 7 and 8 and hence Least common multiple is 56
LEt us make equivalent fractions
7/8 = 49/56
3/7=24/56
Difference i.e. Katie wrote more than her brother = 49/56-24/56
=25/56
