Why do people hate someone just because of the color of their skin? :(
Imaginary numbers are taught in high school algebra, which I think imaginary numbers are taught in 10th or 11th grade.
Step-by-step explanation:
You need to find six combinations of a and b such that a² + b² = 7.
a = 1, b = √6
a = √2, b = √5
a = √3, b = 2
a = 2, b = √3
a = √5, b = √2
a = √6, b = 1
Answer:
Enterprise charges more for a 6 day rental. ($284 for Hertz and $294 for Enterprise). Avery would save $4 if he rented with Hertz for 4 days.
Step-by-step explanation:
H = Hertz
E = Enterprise
x = Days rented
T = Total cost for x days, in $
<u>Hertz:</u> TH = 42x + 32
<u>Enterprise: </u> TE= 45x + 24
====================
6 Day Rental:
TH = 42*(6) + 32, = $284
TE = 45*(6) + 24 = $294
4 Day Rental:
TH = 42*(4) + 32, = $200
TE = 45*(4) + 24 = $204

So, Katherine can do 0.1 of the job per hour. (if she needs 10 hours for the job, each hour she can do the whole divided by the time, so 1/10, which is 0.1)
if in two hours she and Marina can be done, then Marina will do 1(the whole job)-2/10 (twice as much as she can do in an hour)=0.8 of the job. So if Marina does 0.8 of the job in two hours, each hour she will do half of it: 0.4 - and this is the correct answer
