Answer:
4
Step-by-step explanation:
12 can be multipled by 4 and 4 and 8 can be multipled by 4 and 2 so 4 is the greatest common factor
You multiply 5 times 8 so that will give you 40, so the answer is 40
Answer: $509 per week
Explanation:
in order to find how much Robin earned per week, we just need to divide the total amount earned by the number of weeks:
In this case, we have
total amount = $4,581
Nweeks = 9
So, the earn per week is
So, Robin earned $509 per week.
Hi there!
We can set up a ratio to model the problem...
540/3000 = x/100
Now, just cross multiply and solve for x.
54000 = 3000x
x = 18
Therefore, 18 percent of last semester's college costs was spent on books. Hope this helped and have a great day!
Answer: option a.
Step-by-step explanation:
In polar coordinates we have that:
x = r*cos( θ)
y = r*sin( θ)
we know that x = 4 and y = 4. now let's analyze the options:
a) x = 4√2*cos(45°) = 4 nice.
y = -4√2*sin(225°) = 4 nice
Option a is correct
b) x = 4√2*cos(315°) = 4 nice
y = -4√2*sin(135°) = -4 incorrect
option b is not correct
c) x = 4√2*cos(135°) = -4 incorrect
Option c is not correct
d) x = 4√2*cos(225°) = -4 incorrect
option d is not correct
