there is a 1/2 probability of getting heads on any one flip
since the first one landed on heads you have a 1/2 probability f getting a 2nd one
Probability = 1/2
We have been given prism J and prism K have the same volume. A cube J with height 10, length 4 and width 3 A right angled triangular prism K with breadth 10, height 3 and width w. We are asked to find width w of the prism K.
We will use formulas of volume of cuboid and volume of triangular prism.
Now we will equate both volumes as we are told that prism J and prism K have the same volume.
Therefore, the width w of prism K is 8 units.
Answer: We should use the correct formula for tan α (which is opposite
leg over adjacent leg) tan α = 5/b
Step-by-step explanation:
See attached file
We must use the for equation of tan α = BC/AC
tan α = BC/ b tan α = 5/b tan 30⁰ = 1/√3
b = 5/√3 ⇒ b = 5/1.7320
b = 2.8868 cm
Answer:
30,40,50
Step-by-step explanation:
If it is a right triangle then the pythagorean theorum would work
a^2+b^2=c^2
30^2+40^2=50^2
900+1600=2500
2500=2500
this means that 30,40,50 is the right answer
*******extra********
also 30,40,50 is a pythagorean triplet
pythagorean triplets form right angles
this one came from the original triplet of 3,4,5---just multiply by 10
