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

Ok so 6^5
6x6x6x6x6 = 7776
7776x=20
Then we divide each side by 7776
7776x = 20
——— ———
7776 7776
X= 0.00257202
Estimate: 0
The terms 9r^2 and 6r^2 are like terms. We add the numbers to the left of the "r^2" to get 9+6 = 15.
So 9r^2+6r^2 becomes 15r^2
The r^2 stays the same. We do not say something like r^2+r^2 = r^4. You might be thinking of r^2 * r^2 = r^(2+2) = r^4
When it comes to adding like terms, we keep the variables the same.
The other pair of like terms are 3r and 2r, so they add to 3r+2r = 5r
--------------------------------------------------------------------------------------------
Overall,
(9r^2+3r+6)+(6r^2+2r) = (9r^2+6r^2)+(3r+2r)+6
(9r^2+3r+6)+(6r^2+2r) = 15r^2+5r+6
Answer:
3 cm
Step-by-step explanation:
So the area of the total circle is:

If you remove the outer band you have the area of the inner circle

This means that the inner circle had an area of
area = pi * r^2
9 pi = pi * r^2
r =

So the radius of the inner circle is 3.
