3 0
     n² - 4n = 0
n(n) - n(4) = 0
    n(n - 4) = 0
n = 0    or    n - 4 = 0
                     + 4 + 4
                        n = 4

Solution Set: {0, 4}

if a 16 ounce nectar feeder concede about 80 hummingbirds a day how many hummingbirds would you expect to be able to feed with a
tekilochka [14]
In the given question, it is already given that the 16 ounce feeder can feed about 80 humming birds. It has to be found the number of birds that a 12 ounce feeder can feed.
Now coming back to the problem.
The number of humming birds that a 16 ounce feeder can feed = 80
The number of humming birds that 1 ounce feeder can feed = (80/16) * 1
                                                                                                 = 5 * 1
                                                                                                 = 5 birds
Then
The number of humming birds that a 12 ounce feeder can feed = (12 * 5) birds
                                                                                                       = 60 birds
So a 12 ounce feeder can feed 60 humming birds.

olga_2 [115]

Answer:

the first option

Step-by-step explanation:

solution:

distance: d=1/4 lc (because is a quarter of a circle)

length of the circumference: lc=2 pi r

pi: constant=3.14

radius of the circle: r=80 feet

replacing pi and r in the formula of lc:

lc=2 pi r

lc=2 (3.14) (80 feet)

lc=502.4 feet

replacing lc in the formula of d:

d=1/4 lc

d=1/4 (502.4 feet)

d=502.4/4 feet

d=125.6 feet
