Since 3=30/10, (30+1)/10=31/10. 31s/10=(30+1)/5 ( we get 30 because 5*6=30) = 31/5. Multiplying both sides by 10, we get 31s=62 (since 5 is a factor of 10, we can do 10/5 =2 and multiply 2 by 31). Dividing both sides by 31, we get s =2

Pavel [41]

Answer:

Mary = 24

Chau = 15

David = 48

Step-by-step explanation:

The formula is

Mary + Chau + David = 87

And we know that

Chau = Mary - 9

David = Mary * 2

So when we fill this in

Mary + Mary - 9 + Mary * 2 = 87

4Mary - 9 = 87

4Mary = 96

Mary = 24

Chau = Mary - 9 = 15

David = Mary * 2 = 48

xeze [42]

Answer-

Mary should pour 150.8 in³ water into the vase.

Solution-

The volume of the cylinder is given by,

$V=\pi r^2h$

Where,

r = base circle radius = 3 in,

h = height of the cylinder = 8 in,

Putting the values,

$V=\pi \times 3^2\times 8$

$=\pi \times 9\times 8$

$=226.2\ in^3$

As Mary has to fill the vase $\dfrac{2}{3}$ th, so the amount of water would be,

$=\dfrac{2}{3}\times 226.2=150.8\ in^3$
