Suppose that y varies directly with x and y =10 when x = 20. What is y when x=15
Vanyuwa [196]

y=13.34 when x=15

Step-by-step explanation:

We are given that x varies directly with y i.e y ∝ x

We know that: y ∝ x then

y= k/x

where k is constant.

So, if y=10 and x=20 we can find k

y=\frac{k}{x}\\10=\frac{k}{20}\\ k=10*20\\k=200

Now, we need to find y when x=15

We know that k = 200,

So, y=\frac{k}{x}\\y=\frac{200}{15}\\y=13.34\\

So, y=13.34 when x=15

In a box containing a dozen eggs ,3 eggs are rotten .What fraction of eggs are not rotten?​
Minchanka [31]

Answer:

3/4 of the eggs are not rotten.

Step-by-step explanation:

a dozen = 12 eggs

3+3+3+3 = 12

3x4 = 12

1/4 = 3/12

2/4 = 6/12

3/4 = 9/12   <--- |

4/4 = 12/12        |

12-3 = 9  ---------|

SO 3/4 eggs are not rotten
