Will solve this problem using something called, "proportions."
Where one thing is proportional to another thing.
While this isn't always the case, most of the time the two similar measurements they gave you are the measurements you'll be using as your proportion. This is true in this particular case.
50/17 = x/10
Cross multiply!
17x = 500
Solve for x!
x = 500/17 = 29.41
Rounded off the tree is:
30 ft tall!(Or, 29 ft tall depending on how you want to round it)
First step: name the sides according to geometry standards, namely, the sides are named the same lowercase letter as the opposing angle. A revised diagram is shown.
Second step: we need to know the relationships of the trigonometric functions.
cosine(A)=cos(63) = adjacent / hypotenuse = AC/AB .................(1)
sine(A)=sin(63) = opposite / hypotenuse = CB/AB .......................(2)
We're given AB=7, so
using (1)
AC/AB=cos(63)
AC=ABcos(63)=7 cos(63) = 7*0.45399 = 3.17993 = 3.180 (to three dec. figures)
Using (2)
BC/AB=sin(63)
BC=ABsin(63) = 7 sin(63) = 7*0.89101 = 6.237 (to three dec. figures).
4/9 of 351 pages mean (4/9)x351 = (4x351)/9 = 156 pages
To find the total length we justadd the llength of the vBulletin peices together 9 +5.59 + 16 . 8 = 31.39
The total length is 31.39
Answer: 2√10 - √30
explanation:
ok so they’re asking for the difference between the lengths of the sides of each cube. they have different SA’s (surface areas). all you gotta do is plug in the SA in the given equation to find the length of the side and THEN you subtract the answers and thats how you find the difference between the sides.
given:
s = √(SA/6)
SA1 = 240 m^2
SA2 = 180 m^2
S1 = √(240/6) = 2√10 or 6.32
S2 = √(180/6) = √30 or 5.47
s1 -s2 = 2√10 - √30
