Answer:
π
Step-by-step explanation:
the formula is V = πr2h
pie times radius to the second power times hight
29 36 39 45 49 51
39 + 45 = 84
84 ÷ 2 = 42
Answer: Median is 42.
Answer:
The distance between the hose and the point (P) is 0.9 miles
Step-by-step explanation:
Here we have
Speed of rowing the boat = 3 mph
Speed of waling = 4.5 mph
Since the speed of walking is more than that of to row the boat, the location of where he should dock his boat in order to minimize the total time he would need to reach the house is the shortest distance across the river to the house
Therefore the location of the point (P) should be directly opposite the house across the water and the distance id 0.9 miles.
Answer:
y = -
x + 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (0, 2) and (x₂, y₂ ) = (4, 0) ← 2 points on the line
m =
=
= - 
The line crosses the y- axis at (0, 2) ⇒ c = 2
y = -
x + 2 ← equation of line
There are several ways two triangles can be congruent.
<em> congruent by SAS</em>
<em> congruent by corresponding theorem</em>
In
and
(see attachment), we have the following observations
--- Because O is the midpoint of line segment AD
--- Because O is the midpoint of line segment BC
---- Because vertical angles are congruent
---- Because vertical angles are congruent
Using the SAS (<em>side-angle-side</em>) postulate, we have:

Using corresponding theorem,
---- i.e. both triangles are congruent
The above congruence equation is true because:
- <em>2 sides of both triangles are congruent</em>
- <em>1 angle each of both triangles is equal</em>
- <em>Corresponding angles are equal</em>
