Answer: First option of STATEMENT and third option of REASON are correct.

Step-by-step explanation:

Since we have given that

$\frac{AD}{DB}=\frac{CE}{EB}$

We need to prove that DE is parallel to AB.

For this we need to use the converse of BPT theorem.

which states that if the corresponding parts of the triangle is in same ratio, then the line joining the points of other two sides parallel to the third side.

So, we have ,

$\frac{AD}{DB}=\frac{CE}{EB}\\\\\frac{AD}{DB}+1=\frac{CE}{EB}+1(\text{ Addition property of equality)}\\\\\frac{AD+DB}{DE}=\frac{EC+EB}{EB}\\\\\frac{AB}{DB}=\frac{BC}{EB}$

Hence, First option of STATEMENT and third option of REASON are correct.

The formula for the volume V of a cylinder is V = πr2h, where r is the radius of the base and h is the height of the cylinder. S

lana [24]

Answer:

Part A) $h=V/(\pi r^{2})$

Part B) $h=4\ cm$

Step-by-step explanation:

Part A)

we have the formula of the volume of a cylinder

$V=\pi r^{2}h$

Solve for h

That means ----> isolate the variable h

Divide both side by πr²

$V/(\pi r^{2})=\pi r^{2}h/(\pi r^{2})$

Simplify

$V/(\pi r^{2})=h$

Rewrite

$h=V/(\pi r^{2})$

Part B) Find the height of a cylinder with a volume of 36π cm3 and a base with a radius of 3 cm

we have

$V=36\pi\ cm^3$

$r=3\ cm$

substitute in the formula and solve for h

$h=36\pi/(\pi 3^{2})$

$h=4\ cm$

The figure below shows a parallelogram ABCD. Side AB is parallel to side DC and side AD is parallel to side BC: A quadrilateral

il63 [147K]

The postulate that is used in order to prove the congruency of the triangles is the ASA which means (Angle – Side – Angle). The property that is applicable for the congruency of DB to itself is the reflexive property. Therefore, the answer to this item is the second choice.
Hope I helped! :)

Parker is planning to build a playhouse for his sister.The scaled model below gives the reduced measures for width and height. H

kipiarov [429]

Answer:

The cross multiplication would be 10(350) = 22(x).

Step-by-step explanation:

We would first convert meters to centimeters. There are 100 cm in a meter; this means 3.5 m = 3.5(100) = 350 cm.

The ratio of the height to base of the model is 10/22. The ratio of the playhouse would then be x/350. This gives us

10/22 = x/350

Cross multiplying, we would have 10(350) = 22(x).
