A trapezoid is a quadrilateral that has two parallel sides with a height.
<h3>The proof for trapezoid</h3>
From the diagram, AK = 1/2(AD-BC)
The combination of the bases of the equilateral triangle and the parallelogram is = the base of the trapezoid.
Therefore, BC = AD - 2AK
Make AK the subject of formula,
AK= 1/2 (AD -BC)
- From the second equation given,
KD = 1/2(AD - BC). This is wrong because of the following,
BC is parallel to KD.
Therefore length of KD = BC - AK and not KD = 1/2(AD - BC).

Answer:
About 6 hours.
Step-by-step explanation:
The cylinder has a diameter of 10 meters and a depth of 1.4 meters.
First, we can find the volume of the cylinder, given by the formula:
Where r is the radius and h is the height (or depth, in this case).
Since our diameter is 10, our radius is 5.
Therefore, the volume of the cylinder will be (using 3.14 as π):
Since water is pumped at a rate of 18 cubic meters per hour, it will take then:
So, it will take about 6 hours for the water to completely fill the pool.

5(9)=45
v=bh
v=(45)(3.2)
v=144
Answer:
your answer is 45
Step-by-step explanation: it is 45 because 30 divided by 2/3 is 45

Step-by-step explanation:
Julia spends in math.
and spends in spelling.
Lets make for calculation propuses.
Julia spends doing her math and spelling homework.
And lets make
and
So, Julia spends in reading.
If I divide an hour into 4 equal units, each unit equals 15 min, so 1 unit is 15 min.
Julia spends 15 min in reading.
