Based on the task content; If you multiply both sides of an inequality by a negative number, the inequality symbol should be reversed always. Option B
<h3>Multiplication of inequality</h3>
Based on the rule of inequality, whenever you multiply or divide an inequality by a negative number, you must flip the inequality sign.
For instance,
-4x > 12
divide both sides by -4
x < 12/-4
x < -3
If you multiply both sides of an inequality by a negative number, the inequality symbol should be reversed always.

All isosceles trapezoids have congruent base angles.
Option A
<u>Explanation:</u>
An isosceles trapezoid is a convex quadrilateral with a line of symmetry bisecting one pair of opposite sides.
Properties of isosceles trapezoid:
- Opposite sides of an isosceles trapezoid are the same length (congruent).
- The angles on either side of the bases are the same size/measure (congruent).
- The bases (both top and bottom) of an isosceles trapezoid are parallel.
Note: Refer the attached file for the image of an isosceles trapezoid.
All isosceles trapezoids come into the category of trapezoids but all trapezoids cannot be marked as isosceles. Clearly, if a trapezoid has congruent legs, it is an isosceles trapezoid.
If a trapezoid has one pair of congruent base angles, then the trapezoid is isosceles. A trapezoid is isosceles if and only if its diagonals are congruent.
In the case of quadrilaterals, if the quadrilateral is an isosceles trapezoid, then each pair of base angles are congruent.
Answer:
A
Step-by-step explanation:
30% of 100 = 30
100 - 30 = 70
15% of 70 = 10.5
70 - 10.5 = 59.5
Answer:
A total of 8 (eight) completely filled cups.
Step-by-step explanation:
Recall that 1 milliliter is the SAME as 1 cubic cm. Therefore, the 275 ml cup holds exactly 275 cm^3 of water.
Now calculate the volume of water in the container. Since the container measures 19 cm x 6 cm x 30 cm, its total volume is:
Volume = 19 x 6 x 30 = 3420 cm^3
The amount of water in it fills 2/3 of its volume, then:
amount of water = 2/3 (3420) = 2280 cm^3
Now to find how many cups can be filled with such amount of water, we do the division:
2280 / 275 = 8.29
Then the maximum number of completely filled cups is: 8
