In a ten pin bowling the highest possible score in a single game is 300. At one point in the season, John had an average score o

Sindrei [870]

Answer:

John need to get 293 in his next game to bring his average up to 183.

Step-by-step explanation:

John starts with N games played and averaging 177 points per game.

In game N+1, John scored 199 points.

$\frac{177N + 199}{N+1}=178\\177N+199=178N+178\\N=21\\$

So, John has now played (N+1) = 22 games.

We need to know what score John needs in game 23 to bring his average to 183.

$\frac{177*21 + 199+Y}{23}=183\\3916+Y=4209\\Y=293\\$

AlekseyPX

Answer:

192 Kids' Lunches are possible.

Step-by-step explanation:

The client must make 5 decisions:

1) Size (junior, small, medium, large)

2) Cheese (with or without)

3) Type of bun (white, wheat)

4) Side order (fries, onion rings, fruit cup)

5) Drink (orange, grape, cherry, lemonade)

Since the client must make all 5 decisions all the time, we will multiply the number of options we have:

1) For size, he has 4 options,

2) For cheese, he has 2 options,

3) For type of bun, 2 options,

4) For side order, 3 options,

5) For drink, 4 options.

Therefore, the number of total options he has is 4 x 2 x 2 x 3 x 4 = 192 Kids' Lunches.

Prove 2/sqrt3cosx+sinx=sec(pi/6-x)

dlinn [17]

Thus L.H.S = R.H.S that is 2/√3cosx + sinx = sec(Π/6-x) is proved

We have to prove that

2/√3cosx + sinx = sec(Π/6-x)

To prove this we will solve the right-hand side of the equation which is

R.H.S = sec(Π/6-x)

= 1/cos(Π/6-x)

[As secƟ = 1/cosƟ)

= 1/[cos Π/6cosx + sin Π/6sinx]

[As cos (X-Y) = cosXcosY + sinXsinY , which is a trigonometry identity where X = Π/6 and Y = x]

= 1/[√3/2cosx + 1/2sinx]

= 1/(√3cosx + sinx]/2

= 2/√3cosx + sinx

R.H.S = L.H.S

Hence 2/√3cosx + sinx = sec(Π/6-x) is proved
