Which of the following is the statement below describing? If a point is on the perpendicular bisector of a segment, then it is e
Bezzdna [24]

Answer:

(C) Perpendicular bisector theorem

Step-by-step explanation:

(A) Right angle theorem : The right angle theorem states that if two angles are supplementary and congruent, then these two angles are right angles.

(B) Converse of perpendicular bisector theorem: The converse of  perpendicular bisector theorem states that If a point is equidistant from the endpoints of a segment, then it is on the perpendicular bisector of that segment.

(C) Perpendicular Bisector Theorem: The Perpendicular Bisector Theorem states that  If a point is on the perpendicular bisector of a segment, then it is equidistant from the endpoints of the segment.

(D) Pythagorean theorem: The Pythagorean theorem states that in the right angled triangle, the square of the hypotenuse of the triangle is equal to the sum of the squares of the other two sides that is:

(Hypotenuse)^2=(Base)^2+(Perpendicular)^2

Since, the given statement is the statement of the Perpendicular bisector theorem, thus  option C is correct.

A multi-layer cake is in the shape of a right cylinder. The height of the cake is 20 centimeters, and its radius is 10 cm. If ea
gizmo_the_mogwai [7]

Answer:

There are total 5 layers.

Step-by-step explanation:

A multi-layer cake is in the shape of a right cylinder.

Height of the cake is = 20 cm

Radius is = 10 cm

Each of the cake layers has a volume of approximately 1,250 cm³.

Means, the volume of 1 cylindrical layer is 1250 cubic cm with radius as 10 cm and we have to find the height.

Volume of the cylinder is given as:

V=\pi r^{2} h

1250=3.14\times(10)^{2}\times h

1250=314 h

h=\frac{1250}{314}

h = 3.98 or approximately height of 1 layer is 4 cm.

As the cake's height is 20 cm so, there are \frac{20}{4}=5 layers in the cake.

Answer: There are 5 layers in the cake.

Which solid has two bases that are triangles and three lateral surfaces that are rectangles?
arlik [135]
Answer is triangular prism.

Pyramids have only 1 bases so they cannot be the answer. Prisms on the other hand have 2 bases. Prism sides are rectangles no matter of the shape of the bases.  In the text of the task it is required that bases are triangles therefore rectangular pyramid cannot be the answer.

Correct answer is triangular prism.
