Svetradugi [14.3K]

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)

astraxan [27]

Answer:

As j decreases, the expression increases.

Step-by-step explanation:

As j decreases, the expression will increase. This is because once it becomes a lower number, it will subtract less from 150, and it will soon eventually add towards with 150, if j is negative.
