jaime bought a jar of 50 vitamins. his two children each take one vitamin each day. the number of vitamins left in the jar after
Reil [10]

Answer:


Step-by-step explanation:

f(x) = 50 - 2x

x = 0  when the vitamins are bought and none have been taken 9 that is day 0).

So the intercept on the y axis  50 - 2(0) = 50 represents this situation ( day = 0 and number of vitamins = 50).

When all the vitamins have been taken f(x) = 0   so we have

50 - 2(25) = 0  This is the intercept on the x axis ( x = 25 days).

The temperature in St. Louis, Missouri, is 31°F. The temperature in Duluth, Minnesota, is -29°F. Is the temperature in St. Louis
Sati [7]

-29 is 29 degrees away from 0 degrees.

31 is 31 degrees away from 0 degrees.

-29 (the temperature in Duluth) is closer to 0, because 29 is less than 31.

What is 575% written as a mixed number?
pav-90 [236]

<u><em>Answer:</em></u>

575% as a mixed number is 5\frac{3}{4}

<u><em>Explanation:</em></u>

575% is equivalent to \frac{575}{100} which is equal to 5.75

5.75 = 5 + 0.75

0.75 can be written as \frac{75}{100}. This value can be simplified by dividing both the numerator and the denominator by 25. This would give us \frac{3}{4}

<u>Back to our number:</u>

5.75 = 5 + 0.75 = 5 + \frac{75}{100} = 5 + \frac{3}{4} = 5\frac{3}{4}

Hope this helps :)
