You need to find out if 57 can be divided evenly by a number other than 1 and 57.

57 is odd, so it is not divisible by 2.

The digits of 57 are 5 and 7. Add 5 + 7 to get 12. Since 12 is divisible by 3 (12/3 = 4), then 57 is also divisible by 3.

57/3 = 19

19 is a prime number, so the only factors of 57 are 1, 3, 19, 57.

57 rows can be divided into 19 sections of 3 rows each or 3 sections of 19 rows each.

Hunter-Best [27]

A group of friends wants to go to the amusement park. They have no more than $320 to spend on parking and admission. Parking is $9.25, and tickets cost $28.25 per person, including tax. Write and solve an inequality which can be used to determine p, the number of people who can go to the amusement park.

___________________________________________

Please, give me some minutes to take over your question

________________________

They have no more than $320 to spend on parking and admission

320 ≥ 9.25 + 28.25*p

9.25 + 28.25*p ≤ 320

320- 9.25 ≥ 28.25*p

310.75/28.25 ≥ p

p ≤ 11

__________________________

Answer

The number of people who can go to the amusement park can be a maximum of 11 people (less than or equal to 11).

sp2606 [1]

Answer:

1 999 000

Step-by-step explanation:

Formula:

$1+2+3+.\ .\ .+n=\frac{n\times \left( n+1\right) }{2}$

………………………………………

Then

$1+2+3+....+1997+1998+1999=\frac{1999\times \left( 1999+1\right) }{2}$

$1+2+3+....+1997+1998+1999=\frac{1999\times \left( 2000\right) }{2}$

$1+2+3+....+1997+1998+1999=\frac{3998000 }{2}$

$1+2+3+....+1997+1998+1999=1999000$
