Given that the point (12,-5) which takes the form (x,y), This implies that:
opposite=-5
adjacent=12
thus using using Pythagorean theorem, the hypotenuse will be:
c^2=a^2+b^2
plugging the values we obtain:
c^2=(12)^2+(-5)^2
c^2=144+15
c^2=169
thus
c=13
but
cos θ=adjacent/ hypotenuse
therefore:
cos θ=12/13
Answer is option . D
Answer:
C
Step-by-step explanation:
you need to find how many cups of water were used in the game:
512-384=128

Answer:
Volume is 80 cc
Ratio is 23 skittles per 20 cubic centimeter
Volume of a skittle is .416 cubic centimeters per skittle
Step-by-step explanation:
Volume = l*w*h = 4*4*5 = 80 cubic centimeters
192 skittles / 80 cubic centimeters is the ratio. You have to simplify it though.
192/80=46/40 23 skittles per 20 cubic centimeters
The volume of a skittle is 80 cubic centimeters/192 skittles = .416 cm^3/skittle
