one would say that the simple interest doubles if the period of time is specified in the contract and the contract is still valid, if the interest amount is available anitime and so on.

So if the amount doubles let's say at half time for which the principal was awarded to the bank, by the end of the contract , the interest amount can be double × just increased by 1.5

Meredith is playing games at an arcade to earn tickets that she can exchange for a prize. She has 255 tickets from a previous vi
aliya0001 [1]

Answer:

20 games.

Step-by-step explanation:

Given:

Meredith is playing games at an arcade to earn tickets that she can exchange for a prize.

She has 255 tickets from a previous visit.

She earns 6 tickets for each game she plays.

Meredith needs 375 tickets to exchange for the prize she wants.

Question asked:

How many games does Meredith need to play?

Solution:

Total tickets needed to exchange for the prize = 375

Meredith already have = 255 tickets

More tickets needed = 375 - 255 = 120 tickets

<u>By unitary method:</u>

She earns 6 tickets by playing = 1 game

She earns 1 ticket by playing = \frac{1}{6} game

She earns 120 tickets by playing =  \frac{1}{6}\times120=\frac{120}{6} =20\ games

Therefore, she needs to play 20 games to earn 120 more tickets.

Pls help me Find the correct answer
IrinaK [193]
I believe the answer would be D, 2y+6/9y-7 x 3/2 because dividing by a fraction is the same as multiplying by its reciprocal (the fraction flipped). 
Hope I helped! ;)

The root x = 1 has multiplicity 3 for the function f(x)=x^3-x^2-x+1. True or false
Ostrovityanka [42]
X^3 - x^2 - x + 1 = 0
Plug in x = 1:-
1 -1 - 1 + 1 = 2 - 2 = 0  so x =1 is a root.

If it has multiplicity 3 then  the function will factor to (x - 1)^3:-

(x - 1)^3 = (x - 1)(x^2 - 2x + 1) =  x^3 - 2x^2  + x - x^2 + 2x - 1 
             
 =  x^3 - 3x^2 + 3x - 1  so it is FALSE
