marishachu [46]

Answer:

There are 178 more boys in Barlow school as compared to Willow school.

Step-by-step explanation:

We are given the following in the question:

Barlow school:

Total number of students = 873

Number of boys =

$=\dfrac{4}{9}\times 873 = 388$

Willow school:

Total number of students = 630

Number of girls =

$=\dfrac{2}{3}\times 630 = 420$

Number of boys =

Total number of students - total number of girls

Thus, Barlow school has greater number of boys than Willow school.

Difference between the number of boys =

$=388-210\\=178$

Thus, there are 178 more boys in Barlow school as compared to Willow school.

2.1 liters of coffee were equally distributed to 30 cups how many millimeters of coffee were in each cup

sattari [20]

Answer: 70 ml of coffee in each cup

Step-by-step explanation:

1 liter = 1000 ml

Amount of coffee given = <em>2.1 liters</em>

$\Rightarrow$ <em>2.1 liters = 2.1 * 1000 = 2100 ml</em>

Total number of cups = 30

$\therefore$ Amount of coffee in each cup = $\frac{Total\ amount \ of \ coffee}{number\ of \ cups}$ = $\frac{2100}{30}$ =70

<em>∵ Amount of coffee in each cup </em>= <u>70 milliliters</u>
