Answer:
(-3)² = 9
Step-by-step explanation:
3 + p = 8...subtract 3 from both sides
p = 8 - 3
p = 5
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:
Can you put the picture the right way pls?
Step-by-step explanation:
Suppose we have two points, A= (1,2) and B=(2,5)
We need to divide the line segment AB obtained by joining these 2 points, in a ratio 2:3,
Then, to find the coordinates of the point (x,y) which will divide the line segment AB (x1,y1) and (x2,y2) we will use the formula,
x=(mx1 + nx2)/(m+n)
y=(my1 + ny2)/(m+n)
Where m:n is the ratio in which it divides
Thus, coordinates will be x= (2*1 + 3*2)/(2+3)
Or x = 8/5
And y = (2*2 + 5*3)/(2+3) = 19/5
Thus the coordinates of the point are (8/5, 19/5) which divide the line in 2:3 formed by coordinates (1,2) and (2,5)
