Answer:
16 years
Step-by-step explanation:
Given data
For the first tree
let the expression for the height be
y=4+x--------------1
where y= the total height
4= the initial height
x= the number of years
For the second tree, the expression is
y=12+0.5x-------------2
Equate 1 and 2
4+x=12+0.5x
x-0.5x=12-4
0.5x= 8
x= 8/0.5
x=16
Hence it will take 16 years for both trees to have the same height
Answer:
it is the 3rd option
Step-by-step explanation:
Answer:
r = 2.55
Step-by-step explanation:
The formula for finding the radius of a circle using the area is r = √A/π
with the r being the radius. the A being the area, and the π being pi (we'll use 3.14).
So the equation should look like this:
r = √(20.4/3.14)
Find the quotient of 20.4/3.14 and round to the nearest tenth
r = √6.5
Find the square root and round to the nearest hundredth
r = 2.55
