4.5 cubic feet is the answer
Answer:
a) 8/19 chance
b) 7/19 chance (I'm not 100% sure)
Step-by-step explanation:
A) since there are 8 prime numbers from 1-19 we can say that the probability is 8 over 19 or 8/19
Answer:
$5?
Step-by-step explanation:
3 x 4=12
12 is a dosen
1.25 x 4=5
6 and 7
the square root of 43 is 6.557
Answer:
unit
Step-by-step explanation:
Since Here Δ ABC is a isosceles triangle.
Also,
and
Thus, ∠ ADH = 90°
That is, Δ ADH is the right angle triangle.
In which, AD = a unit and HD = b unit
And, By the definition of Pythagoras theorem,
![AH^2 = HD^2 + AD^2](https://tex.z-dn.net/?f=AH%5E2%20%3D%20HD%5E2%20%2B%20AD%5E2)
⇒ ![AH^2 = a^2 +b^2](https://tex.z-dn.net/?f=AH%5E2%20%3D%20a%5E2%20%2Bb%5E2)
⇒ ![AH = \sqrt{a^2+b^2}](https://tex.z-dn.net/?f=AH%20%3D%20%5Csqrt%7Ba%5E2%2Bb%5E2%7D)
Since, the perimeter of a triangle = sum of the all sides of the triangle.
Therefore, perimeter of ΔADH = AD + DH + AH
=
unit
