Gracie is sharing 75 marshminnows among 4 of her friends. If each of her friends gets
sukhopar [10]

Given:

Gracie is sharing 75 marshminnows among 4 of her friends.

Each of her friends gets  the same number of marshminnows, and she gives them as many marshminnows as possible.

To find:

The remaining number of marshminnows she has.

Solution:

We have,

Total number of marshminnows = 75

Number of friends = 4

Divide 75 by 4.

4|\overline{75}|{18}\\                -4\\\text{\quad }\overline {35}  \\ -32\\\text{\quad }\overline {\ 3\qaud }

Here, quotient is 18 and remainder is 3. It means, each friend can be get maximum 18 marshminnows and the number of remaining marshminnows is 3.

Therefore, the correct option is B.

During your cycling trip, you and your friends often stayed in hostels. The prices of these are listed below.
kiruha [24]

Answer:

  • a) NTRD standard price = $26.30
  • b) range: $11.20 to $33.00, a range of $21.80

Step-by-step explanation:

a) The average is the sum divided by the number of contributors. Let n represent the standard price at Night-Time Rest Days. Then ...

... ($22.45 +18.55 +24.50 +11.20 +n)/5 = $20.60

... 76.70 + n = 103.00 . . . . multiply by 5 and collect terms

... n = $26.30 . . . . standard price at NTRD

b) The lowest standard price is $11.20. The highest breakfast price is $33.00. The range is the difference between these ...

... $33.00 -11.20 = $21.80 . . . . range in cost for a single night

What is the inverse of the function g(x) = 1/2x + 1/2?
m_a_m_a [10]

Step-by-step explanation:

Since g(f(x))=x g ( f ( x ) ) = x , f−1(x)=2x f - 1 ( x ) = 2 x is the inverse of f(x)=12x f ( x ) = 1 2 x .

Replace f(x)f(x) with yy.

y=12xy=12x

Interchange the variables.

x=12yx=12y

Solve for yy.

Rewrite the equation as 12y=x12y=x.

12y=x12y=x

Multiply both sides of the equation by 22.

2⋅12⋅y=2⋅x2⋅12⋅y=2⋅x

Simplify 2⋅12⋅y2⋅12⋅y.

Cancel the common factor of 22.

Cancel the common factor.

2⋅12⋅y=2⋅x2⋅12⋅y=2⋅x

Rewrite the expression.

1⋅y=2⋅x1⋅y=2⋅x

Multiply yy by 11.

y=2⋅xy=2⋅x

Solve for yy and replace with f−1(x)f-1(x).

Replace the yy with f−1(x)f-1(x) to show the final answer.

f−1(x)=2xf-1(x)=2x

Set up the composite result function.

g(f(x))
