1/3 z - 12 = 36
1/3 z - 12 + 12 = 36 + 12
1/3 z = 48
1/3 z = z/3
Then multiply by the denominator, 3 to get 3 on other side of the equation.
3• z/3 = 48 • 3
z = 48 • 3
z = 144.
The solution to your problem is z = 144
If area is 81pi then 81pi=pir^2. Divide both sides by pi and we are left with r^2=81 take the square root of both sides to find the radius is 9 then plug that into the equation for circumference(2pir) so 2pi(9)=18 pi so the answer is E 18pi
I'm guessing 9.1 is a typo and it's suppose to be 9.0. In that case, the answer is D
It can go into 100 feet 4 times. After you add four times you should have 97 and 4/8 or 97 and 1/2
Step-by-step explanation:
The ratio of the perimeters = the scale
P₂ / P₁ = 6 / 4 = 3 / 2
The ratio of the areas = the square of the scale
A₂ / A₁ = (6 / 4)² = (3 / 2)² = 9 / 4
Same for the triangles:
P₂ / P₁ = 6 / 3 = 2
A₂ / A₁ = (6 / 3)² = (2)² = 4
