Pooja writes the ratio x3=y4 to help her increase the size of a two-dimensional shape. If the new value of x is 15 units, what will be the value of y?
To find the value of y when x is 15 units, we can set up a proportion:
x3 = y4
Substitute x = 15 units:
15*3 = y*4
45 = 4y
Divide by 4 on both sides to solve for y:
y = 45/4
y = 11.25
Therefore, when x is 15 units, y will be 11.25 units.
