Explanation :
II. False. a rectangle is a special type of rhombus since a rhombus has all sides equal, while a rectangle has all angles equal. A rhombus has opposite angles equal, while a rectangle has opposite sides equal. The diagonals of a rhombus intersect at equal angles, while the diagonals of a rectangle are equal in length.
I. True. A square is a special case of a rhombus, because it has four equal-length sides and goes above and beyond that to also have four right angles. Every square you see will be a rhombus, but not every rhombus you meet will be a square.
III. False. Trapezoids have only one pair of parallel sides; parallelograms have two pairs of parallel sides. A trapezoid can never be a parallelogram. The correct answer is that all trapezoids are quadrilaterals.
Answer:
Correct choice is B
Step-by-step explanation:
Let x% be your final test score, then the average of all test scores is
Since you must have an average between 80% and 89%, then
X is measured in percent, then the greatest value of x can be 100%. You get that
Hey there!☺
Equation
−(2x+5)+14=22 Simplify both sides
−2x + −5 + 14 = 22 Distribute
(−2x) + (−5+14) = 22 Combine Like Terms
-2x + 9 = 22
-2x + 9 - 9 = 22 - 9 Subtract 9 from both sides
-2x = 13
-2x/-2 = 13/-2
-13/2 Add the negative to 13
x = -13/2
Hope this helps!
Answer:
312π mm^2
Step-by-step explanation:
to find the volume of the figure, you have to calculate the volume of a cone and the volume of a sphere divided it by 2.
The volume of a cone is 1/3 * π * r ^ 2 * h, replacing the information:
V = 1/3 * (6) ^ 2 * (14) = 168π mm^2
The volume of a sphere is 4/3 * π * r ^ 3, replacing the information:
V = 4/3 * π * (6) ^ 3 = 288π mm^2
but since you only have half the sphere
V = 288π / 2 = 144π mm^2
then the total volume is
Vt = 168π + 144π = 312π mm^2
