You can focus on the two sub-triangles ABC and ACD
We know that they are both right triangles, because we're given that AC and BD are perpendicular.
The sides AB and AD are the hypothenuses of these triangles, so we know their length through the pythagorean theorem:
But since we're given 
, the expressions for AD and AB are actually the same expression. This proves that AD=AB, and thus that the triangle is isosceles.
Answer:
78.88%
Step-by-step explanation:
We have been given that
The z-score formula is given by
For 
For 
Now, we find the corresponding probability from the standard z score table.
For the z score -1.25, we have the probability 0.1056
For the z score 1.25, we have the probability 0.8944
Therefore, the percent of the trees that are between 20 and 30 years old is given by
0.8944 - 0.1056
= 0.7888
=78.88%
Since the water bill costs $35, to split it into 2 equal payments, you would simply just half $35 which is $17.50.
Answer:
1? Because its the only number beetween 2 and 0.
Answer:
Pick the best solution.
Step-by-step explanation:
Volume of a cone is V = ⅓πr²h
If cone diameter is 4.3
V = ⅓π(4.3/2)²(5.2) = 25.17148... ≈ 25.17 ft³
If cone radius is 4.3
V = ⅓π(4.3)²(5.2) = 100.685950... ≈ 100.69 ft³
If cone diameter is 5.2
V = ⅓π(5.2/2)²(4.3) = 30.439938... ≈ 30.44 ft³
If cone radius is 5.2
V = ⅓π(5.2)²(4.3) = 121.75975... ≈ 121.76 ft³
