4,800,000/6,000,000 = 48/60 = 8/10 = 0.8
80% of 6,000,000 is 4,800,000
so 4,800,000 is 80% of 6,000,000
Answer:
a.) tanL= 0.533
b.) sinN= 0.882
c.) cosN= 0.471
Step-by-step explanation:
Triangle ABC is similar to Triangle LMN, which means that their corresponding angles are congruents.
Using SOH-CAH-TOA we have,
tanL~tanA= 8/15 = 0.533
sinN~sinC= 15/17 = 0.882
cosN~cosC= 8/17 = 0.471
Answer:
y=4
Step-by-step explanation:
y-y1=m(x-x1)
y-4=0(x-2)
y-4=0
y=0+4
y=4
Answer:
h = 4cm
Step-by-step explanation:
Diameter = 18cm
Radius = Diameter/2 = 18/2 = 9cm
V = 1/3*pi*r^2*h
We know that the volume is 108pi cm^3. We can just plug in 108pi cm^3 for V and we also know that our Radius (r) is 2.
So,
108 pi = 1/3*pi*9^2*h
108 pi = (81pi*h)/3
multiply 3 from both side
108pi*3 = (81pi*h)/3 *3
324pi = 81pi*h
Now divide the 81pi from both side
324pi/81pi = (81pi*h)/81pi
4 = h
So the height is 4cm
