It would be C.60 If you add the column of 16-20 and 21-25 it makes 60.
Answer:
x={0, 2pi/3, pi, 4pi/3}
Step-by-step explanation:
First, move sin x by adding sin x to both sides. sin 2x+ sin x = 0. Next using the double angle identity, sin 2x=2(sin x)(cos x), so 2(sin x)(cos x)+sinx=0. Factoring, sin x(2cos x +1)=0. Solving, sin x=0 and 2cos x +1 = 0, or cos x = -1/2.
sin x = 0. Using the unit circle, sin x=0 when x=0 and x=pi.
cosx=-1/2. Using the unit circle, cos x= -1/2 when x=2pi/3 and x=4pi/3.
Answer:
Each kid will get 2.5 submarine sandwiches
Step-by-step explanation:
Answer:
V = 65.548 cm³
Step-by-step explanation:
We have,
Volume of a ball is 4 cubic inches or
.
We know that, 1 inch = 2.54 cm
It is required to convert this volume to cubic centimetre or
.

So, the volume of the ball is 65.548 cm³.
