Ph will be equal to the sum of pn and nh. Thus:
ph = pn + nh
17 = pn + 12
pn = 5
nh = pn + hm
12 = 5 + hm
hm = 8 inches
Answer:
The answer to your question is: BC = √65 or 8.05 u
Step-by-step explanation:
Data
AD = 12 u
BD = 15 u
AC = 4 u
BC = ?
First calculate the length of AB using the pythagorean theorem
BD² = AB² + AD²
AB² = BD² - AD²
AB² = 15² - 12²
AB² = 225 - 144
AB² = 81
AB = 9 u
Now, use the pythagorean theorem to find BC
AB² = BC² + AC²
BC² = AB² - AC²
BC² = 9² - 4²
BC² = 81 - 16
BC² = 65
BC = √65 or 8.05 u
Find the slope a, then using y-y1=a(x-x1)
The volume is the product of length, width, and height. This is a formula you should commit to memory.
.. V = l*w*h
The base is square, so the length and height are both 25 mm. The length is given in cm, so you need to convert units so all the units match*. You know 1 cm = 10 mm, so the length is 120 mm. Or, if you convert the units of the base, you get the base is 2.5 cm square.
The numbers come out smaller and perhaps more understandable if they are given in cm, so let's do that.
.. V = (12 cm)*(2.5 cm)*(2.5 cm)
.. V = 75 cm^3
