snow_tiger [21]

Answer:

  • 5 runs

Step-by-step explanation:

Initial number is 64 players

<u>Number of players reduce twice every run and will be equal to 2 to reach the grand final</u>

  • 64*(1/2)^x = 2
  • (1/2)^x = 1/32
  • 2^-x = 2^-5
  • -x = -5
  • x = 5

Number of runs is 5

64 > 32 > 16 > 8 > 4 > 2

iragen [17]
So, to solve this, we use this equation:
3700 + 0.05(3700)
But, if we want to make it shorter:
1.05(3700)
Now you just multiply(you may want to use a calculator)
1.05(3700) = 3885
She will pay $3885

Solve x and y please need it for tomorrow
Evgen [1.6K]
Solve for x by cross multiplying then isolating the variable:
\frac{9}{15}= \frac{x}{10}                     cross multiply
15x=90                     Isolate the variable
x=6
Solve for y by cross multiplying then isolating the variable:
\frac{9}{15} = \frac{6}{y}          cross multiply
9y=90               Isolate the variable
y=10

Tickets for an American Baseball League game for 3 adults and 3 children cost less than $75, while tickets for 2 adults and 4 ch
nikitadnepr [17]
<h3>No, the cost of 1 adult ticket cannot be $ 20 and the cost of 1 children ticket is not $ 8.</h3>

Step-by-step explanation:

Let us assume the cots of ticket for 1 adult  = $ x

Let us assume the cots of ticket for 1 children  = $ y

So, the cost of ticket for 3 adults = 3 x ( Cost of 1 adult ticket) =  3 x

The cost of ticket for 3 children  = 3 x ( Cost of 1 children ticket)  =  3 y

Also, given the combined cost of 3 adult and children ticket is less than $75.

⇒  3 x +  3  y < 75  ... (1)

Similarly,  the cost of ticket for 2 adults = 2 x

The cost of ticket for 4 children   = 4 y

⇒  2 x +  4  y < 62  ... (2)

Now, solving for the values of x and y, we get:

3 x + 3 y < 75 or, x + y < 25   ⇒ x = 25 - y ( substitute in 2)

2 x +  4  y < 62  or, x +  2 y < 31

⇒   25  - y + 2 y < 31

or, y + 25 < 31

or, y < 6

⇒ x = 25 - 6  = 19

or, x < 19

So, the cost of 1 adult ticket  is x and is less than $19.

The cost of 1 child ticket  is y  and is less than $6.

Hence, by above statement, NO the cost of 1 adult ticket  can not be $ 20 and the cost of 1 children ticket is not $ 8.
