Answer:</h2>
(a) Describe a property of squares that is also a property of rhombi =
- The sides are the same length. The opposite angles are equal.
- Each of the diagonals is the same length and intersects at right angles to each other.
- The point of intersection of the diagonals divides the diagonal into two equal parts.
- Has two axes of symmetry.
- Can be framed with exactly four ways.
- Has a half-turn symmetry.
(b) Describe a property of squares that is not a property of rhombi =
- Has 4 axes of symmetry and rotational symmetry level 4
- Can occupy it in 8 ways
- All four sides are the same length (AB = SM = CD = AD)
- Parallel sides (AB // CD and BC // AD)
- Each angle is the same size as a square
- The diagonals are the same length (BD = AC)
- The diagonals intersect at right angles and bisect the length (AO = OC = BO = OD)
(c) Describe a property of squares that is not a property of rhombi =
- Opposite sides are parallel and the same length (AB = DC and AB // DC, AD = BC and AD // BC) The opposite angles are equal ( and).
- Two adjacent angles are 180o or are complementary.
- Sum of all angles = 360o Its diagonals divide the parallelogram into two equal parts.
(d) Describe a property of rectangles that is not a property of parallelograms =
- Has four sides that are the same length.
- Has four right angles.
- Has two diagonals that intersect at right angles to each other.
- Has quadruple symmetry rectangular.
The volume of the gallon is 6000 gallon
the rate of water flow per min is f(t)=300t^2
a] amount of water that flowed in the first 7 minutes=7/60 hours will be:
f(7)=300(7/60)^2
solving the above we get
f(7)=7/12 gallons
b] The time taken for the tank to be empty will be as follows:
amount of water that will flow out for the tank to be empty will be 6000 gallons
thus,
6000=300t^2
this can be simplified to
20=t^2
t^2-20=0
solving this we get:
t=-2√5 or 2√5
the time taken for the tank to be empty will be t=2√5 hours=5.4721 hours

Answer:
<h3>
x = 10.0 </h3>
Step-by-step explanation:
tan(35°) ≈ 0.7002
from triangle:
tan(35°) = 7/x
so:
7/x = 0,7002
7 = 0.7002•x
x = 7/0.7002 = 9,9971...
x ≈ 10.0
