(f○g)(x)=√(7(x+8))

(f○g)(x)=√(7x+56)

Since there is no real square root of a negative value, the smallest value in the domain would make the radicand equal to zero.  x=-8 is the smallest number in the domain of (f○g)(x)

Ruby plans to make 3 quilts per month until she makes 15 quilts. She figures this will take 1/5 month. Which is NOT a reason why
pashok25 [27]

Answer: c)She should have multiplied 15 by 3 instead of dividing.


Step-by-step explanation:

Number of quilts Ruby plan to make in one month= 3

which means if Ruby makes more than 3 quilts, the time will be more than 1 month.

To find the number of months to make 15 quilts, she need to divide 15 by 3

Thus, the number of months to make 15 quilts=5

Her answer was 1/5 which was absolutely wrong as if she is making 3 quilt in 1 month then in 1/5  month she would make fewer than 3 quilts.

She divides 3 by 15 instead of 15 by 3, thus but the unit is quilts not months.

Thus the only wrong option is c)She should have multiplied 15 by 3 instead of dividing.

How do you write 4/6 as a unit fraction
lawyer [7]

Answer:

1/6

Step-by-step explanation:

1/6 + 1/6 + 1/6 + 1/6 = 4/6. A unit fraction has a numerator of 1 so since 4 is the numerator in 4/6 You should add 1/6 four times.

Hope this helps!
