Do you notice anything strange about those points ?

(0, 1),
(1, 2),
(2, 4),
(3, 8).

The y-coordinate of each point is (2) raised to the power of the x-coordinate.

First point:   x=0, y=2⁰ = 1
Second point: x=1, y=2¹ = 2
Third point:    x=2, y=2² = 4
Fourth point: x=3, y=2³ = 8

The equation of the curve appears to be

   y = 2 ^ x .

So, after 10 hours, x=10, and y = 2¹⁰ = 1,024 .

NeTakaya

Answer:

The required number of bowls are 5.

Step-by-step explanation:

Given : A sugar bowl holds 237 grams. You have a one kilogram bag of sugar.

To find : Estimate how many bowls of sugar you can fill from the bag?

Solution :

1 bowl can hold 237 gram of sugar.

We have, 1 kg of sugar or 1000 gram of sugar.

According to question,

237 gram of sugar can hold in 1 bowl.

So, 1 gram of sugar can hold in $\frac{1}{237}$ bowl.

1000 gram of sugar can hold in $\frac{1000}{237}$ bowl.

1000 gram of sugar can hold in $4.21$ bowl.

Which means, The required number of bowls are 5.

As 4 bowls have $237\times 4=948$ grams of sugar.

Sugar left is 1000-948=52 grams

That 52 grams is filled into 5th bowl.
