Answer:

1. We assume, that the number 1572 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 1572 is 100%, so we can write it down as 1572=100%.

4. We know, that x is 0.3% of the output value, so we can write it down as x=0.3%.

5. Now we have two simple equations:

1) 1572=100%

2) x=0.3%

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

1572/x=100%/0.3%

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 0.3% of 1572

1572/x=100/0.3

(1572/x)*x=(100/0.3)*x - we multiply both sides of the equation by x

1572=333.33333333333*x - we divide both sides of the equation by (333.33333333333) to get x

1572/333.33333333333=x

4.716=x

x=4.716

now we have:

0.3% of 1572=4.716

lisov135 [29]

Answer:

$l\approx 1.296\,cm$

Step-by-step explanation:

The water density is approximately 1 gram per cubic centimeter, which means that 1 gram of water occupies a volume of a cubic centimeter. Hence, 2.179 grams occupies a volume of 2.179 cubic centimeters.

Let assume volume occupied by the water has a cube-like shape, whose side has the following measure:

$l = \sqrt[3]{2.179\,m^{3}}$

$l\approx 1.296\,cm$

What would you have to show in order to prove that a quadrilateral is a rectangle?

nekit [7.7K]

Answer:

A. Consecutive sides have opposite reciprocal slopes

Step-by-step explanation:

A rectangle is a special case of parallelogram, in which the diagonals bisect each other and are the same length, and all angles are right angles. In order to prove a quadrilateral is a rectangle, it can be shown to be a parallelogram, but one or the other of these additional characteristics must be proven.

A. Consecutive sides have opposite reciprocal slopes

Sides with opposite reciprocal slopes will be perpendicular. That is, the angle between them will be a right angle. If all pairs of consecutive sides meet at right angles, the figure must be a rectangle.

B. All sides are congruent

A rhombus is a quadrilateral in which all sides are congruent. It will only be a rectangle if the diagonals are the same length, or, equivalently, adjacent sides meet at right angles.

C. Opposite sides are parallel

A parallelogram will have opposite sides parallel. It will only be a rectangle if the diagonals are the same length, and/or adjacent sides meet at right angles.

D. Consecutive sides are congruent, opposite sides are not.

This seems a contradiction, as opposite sides are consecutive to the same side. (For example, sides AB and CD are both consecutive to side BC.) If we take this to mean that there are two pairs of consecutive congruent sides, then the figure may be a kite, but isn't necessarily a rectangle unless the other conditions are met.

Additional comment

If sides are horizontal and vertical, the slope of the vertical sides is "undefined." It cannot be shown to be the opposite reciprocal of the slope of the horizontal sides.
