Answer:
27
Step-by-step explanation:
If the ratio is 1:3 multiply that by 9:9 so you effectively get 9:9x3 = 9:27. Or, you can say to yourself if B (3) is 3 times greater than A (1) then B is 3 times greater than 9. So 9x3 = 27
Answer:

Answer:
x = 41/3
y = 199/3
Step-by-step explanation:
Solve using system of equations
x is smaller number, y is larger
eq1> y + 2 = 5x > y = 5x - 2
eq2> 80 = x + y > y = 80 - x
equate
80 - x = 5x - 2
Solving:
x = 41/3
y = 199/3
So first we need to find the area of pizza which is pir^2 radius is 9 so 81pi
Now we need to find area of pizza slice triangle amd subtract its area from pizzas area
Triangles area is (9x5)/2 =22.5
So answer is 81pi-22.5 is left
I think its correct
