Find ten rational numbers between -1 by 5 and 1 by 2 ​
uysha [10]

Answer:

Step-by-step explanation:

First both the rational numbers should have same denominators. So, find least common denominator

Least common denominator is 10

\frac{-1}{5}=\frac{-1*2}{5*2}=\frac{-2}{10}\\\\\\\frac{1}{2}=\frac{1*5}{2*5}=\frac{5}{10}\\\\\\

Now multiply  the numerator  and denominators of the both the numbers by 10.

\frac{-2*10}{10*10}= \frac{-20}{100} \ and \ \frac{5*10}{10*10}=\frac{50}{100}\\\\\\Now\ 10 \ rational  \ numbers \ between\frac{-20}{10} \ and \ \frac{50}{100} \ is \\\\\\\frac{-19}{100},\frac{-18}{100},\frac{-17}{100},\frac{-16}{100}.\frac{-15}{100},\frac{-14}{100},\frac{-13}{100},\frac{-12}{100},\frac{-11}{100};\frac{-10}{100}

insens350 [35]

Answer:

\displaystyle s = -\frac{1}{5}h + 20

Step-by-step explanation:

<em>Time</em><em> </em>is the dependent variable, so you set your function equal to <em>s</em>. Then, the correlation of the graph has a \displaystyle -\frac{1}{5}<em>rate</em><em> </em><em>of</em><em> </em><em>change</em><em> </em>[<em>slope</em>] from the y-intercept of \displaystyle [0, 20],so we choose this answer choice.

Evgen [1.6K]

The complete question is;

A paintball court charges an initial entrance fee plus a fixed price per ball.

P represents the total price (in dollars) as a function of the number of balls used n.

P = 0.80n + 5.50

How much do 10 balls cost?

Answer:

Cost of 10 balls = 8 dollars

Step-by-step explanation:

We are told that;

total price in dollars is given as a function of the number of balls

p = 0.8n + 5.5

Where n is number of balls.

We are told that the price above is price of number of balls plus entrance fee.

Thus, 5.5 dollars is the entrance fee while 0.8n dollars is the price for n number of balls.

Thus,for 10 balls,

Price of 10 balls will be 0.8 x 10 = 8 dollars
