Answer:
1 : 4 : 9
Step-by-step explanation:
Given the ratio of diameters = a : b , then
ratio of areas = a² : b²
Here ratio of diameters = 1 : 2 : 3 , so
ratio of areas = 1² : 2² : 3² = 1 : 4 : 9
Answer:
Step-by-step explanation:
Maximum capacity of the elevator = 2000 pounds
Combined weight of the elevator = 428 pounds
A). Let the possible weights that can be added to the elevator = w pounds
B). Therefore, inequality representing this situation will be,
428 + w < 2000
C). By solving the given inequality,
(428 + w) - 428 < 2000 - 428
w < 1572 pounds
Now we draw this inequality on a number line.
It should be 6 3/5 If not I’m sorry
GCF = 3a^2b
Solution: A, u are correct :)
