Set it up as a ratio to find what 40% of 250 mL is:
 x            40
---      =   ------
250       100
Then it becomes (40*250)/100, which is 100.
Finally, add 100 to 250. Your answer is 350.

Find the slope of the line throught each points (-19,1),(-1,-14)​
telo118 [61]

Answer:

\large\boxed{m=-\dfrac{5}{6}}

Step-by-step explanation:

The formula of a slope:

m=\dfrac{y_2-y_1}{x_2-x_1}

We have the points (-19, 1) and (-1, -14). Substitute:

m=\dfrac{-14-1}{-1-(-19)}=\dfrac{-15}{18}=-\dfrac{15}{18}=-\dfrac{5}{6}

melomori [17]
<h3>Emilo is more than half way done with his run during his water break</h3>

<em><u>Solution:</u></em>

Given that,

During practice, he has to run 40 laps around the track

To find:  Is he more or less than halfway done with his run during his water break

From given,

Half way of his run = 40 \div 2 = 20

After 26 laps, Emilio stops for water

26 > 20

Therefore, 26 is greater than 20

Thus, Emilo is more than half way done with his run during his water break

Divide 4 2/3 &amp; 3 1/3. Simplify the answer and write it as a mixed number.
Leto [7]

Answer:

4 2/3 ÷ 3 1/3= 1 2/5

Step-by-step explanation:

First, you turn the mixed terms into an improper fraction like this

4 2/3 → 14/3 because when you multiply 4 times 3 equaling 12 then having 2 then adding that you get 14/3.

3 1/3 → 10/3 because when you multiply 3*3=9 then having 1 and adding that you get 10/3.

Then, you do KCF which stands for <u>Keep Change Flip</u> so for this you would do: 14/3 ÷ 10/3 → 14/3 × 3/10

14 × 3 = 42 and 3 × 10= 30

Now being 42/30 this is considered an improper fraction in which you have to transform it into a mixed number like this:

(For this you need to find the greatest common factor)

42/30 →  42 and 30 greatest common factor is 6 because they are divisible and factor of 6.

Now you divide both the denominator and the numerator y 6 like this:

42 ÷ 6= 7

30 ÷ 6= 5

Now we have 7/5, this is still an improper number so we see how many times 7 can go to 5 which is once. So we have 1 as whole number, now we put the reminder as the numenator of the mix fraction keeping 5 as being the denominator.

Overall, We have our answer 1 2/5

I hope this helps :D
