Using proportions, it is found that Juan spends 15 minutes on each 5-point problem.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and is solved using a rule of three.

In this problem, the amount of time is proportional to the amount of points the problem is worth. Hence, for a 5-point problem, in a 75-minute time, the time is given by:

t = 75/5 = 15 minutes.

iVinArrow [24]

Answer:

See below

Step-by-step explanation:

f(x)=\frac{2x^{m} }{x+a}

f(x)=\frac{2x^{1} }{x-1}

If x=1, then 1-1=0, which implies a vertical asymptote at x=1 since dividing by 0 is undefined.

g100num [7]

Answer:

0.75 cup = 0.1763 liters

Step-by-step explanation:

From the question:

Using the conversion factors given in question

We are converting

0.75 cup to liters

Step 1

Convert cups to pint

1 cup = 0.5 pints

0.75 cup = x pints

x = 0.75 × 0.5 pints

x = 0.375 pints

Step 2

Convert pints to Quart

1 pints = 0.5 quart

0.375 pint = x quart

Cross Multiply

x quart = 0.375 × 0.5 quart

x quart = 0.1875 quart

Step 3

Convert from quart

1 quart = 0.94 liter

0.1875 quart = x liter

Cross Multiply

x liter = 0.1875 × 0.94 liter

x liter = 0.17625 liters

Approximately to 4 significant figures= 0.75 cup = 0.1763 liters
