A truckload of apples weighs 2550 lbs. If 5 (exact) apples weigh 1250 g, how many apples are in the truck?
egoroff_w [7]

Answer:

There are 4,626 apples in the truck.

Explanation:

Mass of  5 apples = 1250

Mass of an apple = \frac{1250 g}{5}=250 g

Mass of apples in the truck = 2550 lbs

1 lbs = 453.592 g

2550 lbs=2550\times 453.592 g

Let the number of apples with mass of 2550 lbs be a.

a\times 250 g=2550\times 453.592 g

a=\frac{2550\times 453.592 g}{250 g}=4,626.63

4,626.63 ≈ 4,626

So, there are 4,626 apples in the truck.

Answer:

The answer is 2i on right hand side.

Explanation:

We should star by checking the equation from right.

First we check how many Zn r there in left hand side. Which is 1. Let us check how many Znr there in right hand side, there is 1.So Zn is balanced, and don't worry about Znplus2 on right hand side it is just the ions not how many zinc r there.

Now let us check how many I are there left hand side. Which is 2. Now how many I are there in right hand side? Only 1.

So we put 2 behind I.

Now there r 2 I on both sides.

Its simple actually.
