The complete question in the attached figure
Part a)
we know that
ABC is a right triangle
∠ACB=45°
AC=hypotenuse------> 6√2 cm
sin 45=AB/AC-----> AB=AC*sin 45----> AB=6√2*√2/2----> AB=6 cm
the answer part a) isAB=6 cmPart b)
we know that
volume of the pyramid=(1/3)*Area of the base*height
area of the base=50 cm²
height=6 cm
so
volume of the pyramid=(1/3)*50*6----> 100 cm³
the answer part b) is 100 cm³
If 40% reps 98
100% will rep (98/50)*100 = 245
20, 180 - 20, 180 + 20 and 360 - 20
i.e. 20°, 160°, 200° and 340°
Answer:
Answer C: 96 students
Step-by-step explanation:
Take 1/5 of the 480 total students:
(1/5)(480) = 480/5 = 96
Answer C (96 students) is correct.
Answer:
2:5
Step-by-step explanation:
Because if we look 8:20 can be turned into 8/20 and if we simply we got 2/5 and turn it into 2:5
