A laptop is 30% off the regular price of 920$ If a 6% sales tax is added to the cost what is total cost of the laptop

Lunna [17]

Answer

If we had a sale price of 30% off of $1,050then the sale price is 70% of $1,050 or 0.7(1050) Then we add 7% sales tax to that making thefinal price paid 107% of [0.7(1050)] ... 1.07[0.7(1050)] = $786.45

When two of the three numbers are added at a time, the possible sums are 32, 39, 23. What is the sum of all three numbers?

arsen [322]

Answer:

Step-by-step explanation:

Let a, b, and c be those three numbers.

When two of the three numbers are added at a time, the possible sums are 32, 39, 23. Let

$a+b=32\\ \\a+c=39\\ \\b+c=23$

Add these three equations:

$a+b+a+c+b+c=32+39+23\\ \\2a+2b+2c=94$

Divide this equation by 2:

$a+b+c=47$

The sum of all three numbers is 47.

F(n)=−11+22(n−1), left parenthesis, n, right parenthesis, equals, minus, 11, plus, 22, left parenthesis, n, minus, 1, right pare

prisoha [69]

Answer:

$a_1 = -11\\\\a_n = a_{(n - 1)} + 22$

Step-by-step explanation:

An arithmetic sequence is generally given as:

f(n) = a + (n - 1)d

where a = first term and f(n) = nth term, d = common difference

The explicit formula given is:

f(n) = 11 + 22(n - 1)

The recursive formula is made of two statements, the first term and the formula showing how successive terms are related.

Mathematically, it is given as:

$a_1 = a\\\\a_n = a_{(n - 1)} + d$

Therefore, the recursive formula is:

$a_1 = -11\\\\a_n = a_{(n - 1)} + 22$
