Answer:

f(n) = 46 +4n . . . . . . where f(n) is the number of seats in row n

Step-by-step explanation:

The numbers form an arithmetic sequence with first term 50 and common difference 4. The general term for such a sequence is ...

... a[n] = a[1] + d·(n -1)

... = 50 + 4(n -1) . . . . filling in your numbers

... = 46 + 4n . . . . . . . simplify

3 over the power of 2 multiply by 3 over the power of 5
Nostrana [21]

Answer:

3^2 \times 3^5 = 3^7

3^2 * 3^5 = 3^7

Step-by-step explanation:

I assume you mean this:

3^2 \times 3^5

If so, then the rule is that when you multiply two numbers with the same base, you give the same base and add the exponents.

3^2 \times 3^5 = 3^{2 + 5} = 3^7

Out of these numbers which of them differ by 46. 29,17,38,71,35,63,24
mafiozo [28]

Answer:

71

Step-by-step explanation:

Add 46 to each number, see if the sum is in the list. In the set of 7 numbers listed, two of them are even (24 and 38), and the other 5 numbers are odd

71

We do not need to look at all differences.

We need to find two numbers fairly far appart,

and not all look promising.

You could look at approximate differences,

or you could look at the last digit.

71-35 and 63-17 are the only promising differences,

because 71 and 63 are the only numbers large enough to be 46 more than another number in that list,

and when you calculate the last digit you calculate

11-5=6 and 13-7=6.

71-35=36

You plan to take $450 u.s. on a trip to south africa. how many rands is this if one u.s. dollar equals 3.70 rands?
Mumz [18]
$1 = 3.70 rand

$450 is the same as 450 * $1, so multiply both sides of the conversion equation above by 450.

450 * $1 = 450 * 3.70 rand

$450 = 1665 rand
