Multiply the total hours by each portion:
Ally = 60 hours x 0.4 = 24 hours.
Megan = 60 x 1/4 = 60 x 0.25 = 15 hours.
Rachel and Liz = 60 hours - 24 hours - 15 hours = 21 hours total.
Rachel and Liz shared equally so 21 / 2 = 10.5 hours each.
Liz babysat 10.5 hours ( 10 and 1/2 hours).
I believe the correct answers from the choices listed above would be the first and the second option. The conversion factors that are to be used to convert from units of km/min to units of m/hr would be 60 min / 1 h and 1000 m / 1 km. Hope this helps.
X/100 x 3 = 3.21
x = 3.21/3 x 100
=107
107-100=7%
2x2 is 6
4x6 is 24
6 divided by 24 is 0.25
Answer:
Maximum number of turns: 3
Step-by-step explanation:
1. By definition, a polynomial of
degree, has a maximum turning points of
.
2. Therefore, if you have the polynomial given in the problem, which is a polynomial of degree 4 (
, the maximum number of turns can be obtained as following:
![n-1=4-1=3](https://tex.z-dn.net/?f=n-1%3D4-1%3D3)
3. Therefore, you can conclude that the maximum number of turns are 3.
