Answer:
9.95 cm
Step-by-step explanation:
Volume of a cylinder = pi * r² * h
Volume = 500 cm³
Radius, r = 8cm / 2 = 4cm
500 = 3.14 * 4² * h
500 = 3.14 * 16 * h
500 = 50.24 * h
h = 500 / 50.24
h = 9.952229
Height, h = 9.95 cm

Answer: 1.68?
Step-by-step explanation:
i used trigonometry
Adjacent = cos 62 = A/30
cos 62 x 30 = 14 ( rounded off )
A = 14
X = A = cot 58 = A/14
cot 58 x 14 = 1.68
X = 1.68 ( rounded off )
Part A: $1920 because if you change 20%to .2 then .2*1600= 320 and 320+1600=1920
Part B: $320 because 1600/5=320 that is after taxes, before taxes it is $384 because 1920/5=384 you divided it by 5 because it is 1/5, so you divide it by 5 and then multiply it by 1 because 1/5=y/1600 so find y which is what he out in the savings account
Answer:
15:17
Step-by-step explanation:
Since the triangle has a right angle, we may find the length of the unknown side using the trigonometric notations SOH CAH TOA where
SOA stands for
Sin Ф = opposite side/hypotenuses side
Cosine Ф = adjacent side/hypotenuses side
Tangent Ф = opposite side/adjacent side
With respect to ∠B given that ∠D=90°,
BD is the adjacent side
CB is the hypotenuse side
and DC is the opposite side
Hence Sin B = 15/17
