Question

Last year, the world produced 3.5 billon tons of cement and that amount could increase by a billion tons by year 2050. Express the amount expected in 2050 in scientific. Notation and then tell me how much larger it is compared to 1.5 times ten to the seventh power

Answer 1

Answer:

$4.5 \times 10^{9}$ tons.

300 times.

Step-by-step explanation:

Last year, the world produced 3.5 billion tons of cement and that amount could increase by a billion tons by the year 2050.

So, the net production of cement by the year 2050 will be (3.5 + 1) = 4.5 billion tons i.e. $4.5 \times 10^{9}$ tons. (Answer)

Now, this amount is larger than $1.5 \times 10^{7}$ by $\frac{4.5 \times 10^{9} }{1.5 \times 10^{7}} = 300$ times. (Answer)
