The correct option is B or,
t=d(2+3.5)
5.5 hours a day times however many days he or she decides to do so, equals the total number of hours :)
we know that
In a right triangle NPM
cos 71°=adjacent side angle 71°/hypotenuse
adjacent side angle 71°=side NP
hypotenuse=side NM
NP=15
NM=p
so
cos 71=NP/NM
cos 71=15/p
solve for p
p=15/cos 71°
p=46.07----------->p=46.1 units
therefore
the answer is
46.1
Answer:
30
Step-by-step explanation:
Solve for n: 0.22n = 6.6.
- 6.6/0.22 (because for example 3/3 and n/n= 1 so 0.22/0.22 = 1 so we have to divide 6.6 since it is part of the equation and we have to do it on both sides.)
- =30
Answer:
answer C is the right one
Step-by-step explanation:
Volume cylinder is area of the (round) surface * height.
The formula for the area of any circle = pi * radius²
pi * radius²
So the formula for the volume is
Volume cylinder = pi * radius² * height
radius = 15 in and height = 6 in
Substitute this in the formula and you get:
Volume cylinder = pi * 15² * 6
Volume cylinder = pi * 225 * 6
Volume cylinder = pi * 1350
so answer C is the right one
