Answer:
-9.5=z
Step-by-step explanation:
-4.75=z/2
multiply both sides by 2
-4.75(2)=(z/2)(2)
-9.5=z
Answer:
It is proved
Step-by-step explanation:
A curve immersed in the three-dimensional sphere is said to be a Bertrand curve if there exists another curve and a one-to-one correspondence between and such that both curves have common principal normal geodesics at corresponding points.

Well we want to find out how much more will it cost to rent a ski boat than a sailboat for four hours.
All we have to do is Multiply 73 by 4 for the sailboat which gives you $292
Now we do the same for the ski boat. $88 * 4 = $352
So we now have to find out how much more it will cost for a ski boat than a sail boat. All we do is subtract 352 by 292
352

Your answer is $60
Answer:
The measure of smaller angle = 45°
Step-by-step explanation:
Finding the unknown angle
Ratio of the supplementary angles = 3 :1
The angles are 3x , x
Supplementary angles add up to 180°
3x + x = 180
4x = 180
x = 180 ÷ 4
x = 45°
3x = 3*45 = 135°
