Answer:
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.
tons. (Answer)
Now, this amount is larger than
by
times. (Answer)
Answer:
x= 1/5 y= 23/5
Step-by-step explanation:
Y = kxz
Find k first to get the equation.
206 = k*(6*11)
206 = 66*k
Divide both sides by 66.
3.12 = k
y = 3.12xz
y = 3.12(-4*25)
y = 3.12(-100)
y = -312
