Answer:
John is currently 6 years old.
Step-by-step explanation:
2 years ago: x years
Current time: x+2
In 6 years: x+8
EQUATION:
3(x)=x+8= 3x=x+8
(subract x from both sides)
2x=8
x=4
Therefore, John is 6 years old in current time
Answer:
Since length is three times, hence it is 6 inches.
let the width be x.
then, length= 3x
perimeter= 16 inches.
perimeter of a rectangle = 2( L+B)
2(3x+x)=16.
3x+x= 16÷2
4x= 8
x= 2
since length=3x
hence, 3×2= 6 inches
We know that
area of circle =pi*r²
for r=4 ft
area=pi*4²------> 16*pi ft²
<span>the shaded sector of the circle represent 3/4 of the total area
so
3/4*16*pi-----> 12*pi ft</span>²
the answer is
12*pi ft²
