Answer: 3 and 4
Step-by-step explanation: I took the quiz
So when the pool is filled by the two hoses together in 30 minutes, the larger hose itself fills 30/40 = 3/4 of the pool. That means in those 30 minutes the smaller hose fills 1/4 of the pool; and that means it would take the smaller hose 30*4 = 120 minutes to fill the pool alone.
Answer: 5 inches.
Step-by-step explanation:
Let be "x" the length of the airplane (in inches) in Will's drawing.
The first step to solve this exercise is to find the scale factor.
Since the airplane has a 100 foot wingspan and in his drawing the airplane has a wingspan of 10 inches, you get that the scale factor is:
Finally, knowing the scale factor and knowing that the airplane is 50 feet long, you can multiply this lenght by the scale factor in order to find the length of the airplane (in inches) in Will's drawing.
This is:
Its lenght in Will's drawing is 5 inches.
Find the B)'s plot :
21.4 × 21.4 = 457.96 sq.m
A) 360 sq.m
B) 457.96 sq.m
When you compare them, B) is the better option.
So, The farmer should buy B)
It has two solutions because there is two Xs in the equation (x-4) (x-4)=36 which will get u two answers
