AnnZ [28]

Answer:

75

Step-by-step explanation:

Divide 50 by 2/3. Division is the same as asking "how many times can i subtract 2/3 from 59?"

50 \div  \frac{2}{3}

Dividing by a fraction is the same as multiplying by the reciprocal.

50 \times  \frac{3}{2}  = 75

You can subtract 2/3 from 50, 75 times

5miles = 8km. How many km in 80miles?
Zina [86]

Answer:

128

Step-by-step explanation:

Set this up as a proportion with miles on the top and km on the bottom:

\frac{mi}{km}:\frac{5}{8}

If we want to know how many km are in 80 miles, we put the variable with the km stuff on the bottom and 80 on top and cross multiply to solve for the variable:

\frac{mi}{km}:\frac{5}{8}=\frac{80}{x} so

5x = 640 and

x = 128

That means that 80 miles is equivalent to 128 km

The total cost, y, for Leah and x friends to go to an amusement park can be modeled by a
Katarina [22]

Answer:

Range of the function is:

{55.25, 100.50, 145.75, 191.00, 236.25, 281.50}

Step-by-step explanation:

Given that:

Seating capacity of the car = 6

Entrance fee per person = $45.25

Parking fee per car = $10

Leah is accompanied by x friends.

So, the total cost can be modeled as the following linear function:

y=45.25x+10

Now, the value of x i.e. number of friends going with Leah can be any of the following:

0, 1, 2, 3, 4 or 5 (because maximum capacity of the car is 6).

Leah is also going.

So, total number of people can be 1, 2, 3, 4, 5 or 6.

Therefore, the table of x, y can be:

\begin{center}\begin{tabular}{ c c}x & y \\ 1 & 55.25  \\  2 & 100.50  \\   3 & 145.75  \\ 4 & 191  \\ 5 & 236.5   \\ 6 & 281.50   \\\end{tabular}\end{center}

Here, the value of y is nothing but the range of the function.

Therefore, the range of the linear function is:

{55.25, 100.50, 145.75, 191.00, 236.25, 281.50}
