Answer:
<h2>This value is called the common difference</h2>
Step-by-step explanation:
The common difference is the constant value which is repeatedly added to each term in an arithmetic sequence to obtain the next term, it is basically the difference between consecutive numbers
To find the common difference we can subtract the previous term from the first time or the second to the last term from the last term, the idea of finding the common difference is basically subtracting the previous term form the subsequent term.
A GCF is the greatest common factor. It is the largest number that fits into other numbers. A seven cannot fit into a number smaller than itself, that doesn't work. Try to fit 7 into a smaller number like 4, it doesn't work.
Option A is 21 and 3 and Option C is 7 and 1. Those can be eliminated because 7 is larger than 3 and 1.
Option B is 7, 14. 7 Is the largest number that goes into 7 and it goes into 14. So B works.
28 and 7 is Option D. 7 is the largest number that goes into 7 and it goes into 28, so D works.
Answer:
(a) 150
(b) 384
(c) 84
(d) 261
(e ) 480
Step-by-step explanation:
(a)
Let 'a' be a number such that the half of his third is 25; i.e.
Hence, the number is 150.
(b)
Let 'b' be the number such that the quarter of his half is 48 i.e.
Hence the number is 384.
(c)
Let 'c' be the number such that the third quarter or, increased by 17 is 80.
Hence, the number is 84.
(d)
Let 'd' be the number such that its triplet, reduced by 28 is 755
Hence the number is 261.
(e
Let 'e' be the number such that double his third, increased by 80 is 400.
Hence, the value of the number is 480.
The instructor wants the profit to be positive, so
f(n) > 0
70n -400 > 0
n - 400/70 > 0
n > 5 5/7
The instructor must enroll at least 6 students to make a profit.
Answer:
1
Step-by-step explanation:
.75-.25 is .5
1/2 is equal to .5 so .5 +.5 is 1
