- Figure
Figure A is a scale image of Figure B, as shown. (figure a is 6 inches, and figure b is x inches, both squares) The scale that maps Figure A onto Figure B is 1:1 1/3. Enter the value f x - A cuboid
A cuboid has a volume of 768 cm3, and the edges marked x are equal in length. Calculate the value of x - The length 11
The length of a rectangle is four times its width. If the area is 100 m², what is the length of the rectangle? - Highway
A stretch of highway 12 1/4 kilometers long has speed limit signs every 7/8 of a kilometer. How many speed limit signs are on this stretch of highway? - Treasure map
On a treasure map, the actual distance is directly related to the scaled distance. If 15 miles is represented by 3 centimeters on the treasure map, are they equivalent to 135 miles? - Isosceles trapezoid
Find the area of an isosceles trapezoid; if the bases are 12 cm and 20 cm, the arm's length is 16 cm. - Wall and body diagonals
The block/cuboid has dimensions a = 4cm, b = 3cm, and c = 12cm. Calculate the length of the wall and body diagonals. - Median in right triangle
In the rectangular triangle, ABC has known the length of the legs a = 15cm and b = 36cm. Calculate the length of the median to side c (to hypotenuse). - Rectangle area
The length of a rectangle is x units, and the width is y. Dimensions are increased by 10% and 15%, respectively. What is the ratio of the areas of the old and new rectangle? - Parallelogram perimeter
The ABC triangle with sides a = 5cm, b = 3cm, c = 40mm has the center of the sides of the K,L,M. How many cm have the KBLM parallelogram perimeter? - Trapezoid ABCD
ABDC is a trapezoid in which AB and CD are parallel sides measuring 6 and 9, respectively. Angles ABC and BCD are both right angles. Find the length of segment BD. - Cuboid - edges
The sum of all edges cuboid is 8 meters. However, the width is twice shorter as the length, and the height is seven times longer than the width. Determine the dimensions of the cuboid. - N-gon II
What is the side length of the regular 9-gon circumscribed circle of radius 13 cm? - IS triangle
Calculate interior angles of the isosceles triangle with base 40 cm and legs 22 cm long. - Angles
Find the interior angles of a rhombus with area 319.1 cm² and perimeter 72 cm. - Cube wall
The surface of the first cube wall is 64 m². The second cube area is 40% of the surface of the first cube. Find the length of the edge of the second cube (x). - Circle chord
What is the length x of the chord circle of diameter 115 m if the distance from the center circle is 11 m? - Greatest 82502
In triangle ABC, side a = 30 cm b = 7 cm. The length of the third side in cm is a natural number. What is the least and what is the greatest length that side c can have? - Distance 82240
