Answer:
The radius is: 1
Step-by-step explanation:
The equation of a circle in center-radius form is:
Where the center is at the point (h, k) and the radius is "r".
Given the equation of the circle:
You can identify that:
Then, solving for "r", you get that the radius of the circle is:
The correct answer is B- The surface area of B is greater than the surface area of A. I got this answer because...
Figure A's Volume= 60
Figure B's Volume= 60
Figure A's Surface Area= 104
Figure B's Surface Area= 248
So because the volumes are the same I knew it was not C or D, and then I solved the Surface Area for figures a and b and knew the correct answer is B.
Hope that helps. :)
Answer: she wants to rent the car for 11 days.
Step-by-step explanation:
Let x represent the number of additional days that Pamela wants to rent the car for.
Customers can pay $40 to rent a compact car for the first day plus $6 for each additional day. This means that the total cost of using this special for x days would be
40 + 6(x - 1) = 40 + 6x - 6
= 34 + 6x
Also, they can rent the same car for $30 the first day and $7 for every additional day beyond that. This means that the total cost of using this special for x days would be
30 + 7(x - 1) = 30 + 7x - 7
= 23 + 7x
Since she found out that the two specials are equivalent for x days, then
34 + 6x = 23 + 7x
7x - 6x = 34 - 23
x = 11
