You will need the formula for finding the volume of a rectangular prism (cuboid).
V = l x w x h
1. V = x^2 x h
2. To solve for x, you will substitute in the information you know.
150 = x^2 x 24
Divide both sides by 24 to get
6.25= x^2
The square root of 6.25 is 2.5.
x = 2.5 cm
Let the number of islands visited be x and that peninsulas be y
thus,
x+y=19
⇒y=19-x.........i
if he skydives twice in islands and thrice in peninsulas, then the total number of skydives will be:
2x+3y=45.....ii
substituting i in ii we get:
2x+3(19-x)=45
2x+57-3x=45
putting like terms together we get:
2x-3x=45-57
-x=-12
therefore
x=12
and
y=19-x=19-12=7
hence the number of islands visited was 12 and that of peninsulas was 7
U use sin
sin50 = b/10
b=10(0.76)
b=7.6
