Matt claims that the decimal 6.25 is equivalent to the fraction 25/4. Explain how that's incorrect.
sdas [7]
Actually, that is a trick question. Matt is correct because 24/4 is equal to 6. 1/4 is equal to 0.25. Add them together and you get 6.25. I just split 25/4 into 24/4 and 1/4 if you didn't understand what I did.

Lera25 [3.4K]

Answer:

B) 7 cans

Step-by-step explanation:

First task is to determine how many square units we have.

With the rectangle spanning 2 units on the X-axis and 3 unites on the Y-axis, we know that it has an area of 6 square units.

The two triangle shapes sum up to one unit total, since a triangle's area is (base * height) / 2.  Both have a base of 1 unit, and a height of 1 unit... so  (1 * 1) / 2  = 1/2 for each triangle.  Together, they occupy 1 unit.

So, total is 7 square units. Let's imagine it as a 7-unit by 1-unit rectangle, it will be easier to calculate.  Each unit is 5 feet.  So, this rectangle measures 35 (7 * 5) feet long, by 5 (1 * 5) feet wide... for a total of 175 (35 * 5) sq feet.

Since a can of paint can cover 25 sq feet, he'll need 7 cans (175 / 25).

Given ABC=65 and BCD=105. Is it possible that Line AB intersects line CD​
levacccp [35]

Given:

m\angle ABC=65^\circ

m\angle BCD=105^\circ

To find:

Whether it is possible that Line AB intersects line CD​.

Solution:

We have,

m\angle ABC=65^\circ

m\angle BCD=105^\circ

The angles m\angle ABC and m\angle BCD are same sided interior angles.

If two lines are parallel and a transversal line intersect them, then the same sided interior angles are supplementary angles and their sum is 180 degrees.

m\angle ABC+m\angle BCD=65^\circ+105^\circ

m\angle ABC+m\angle BCD=170^\circ

m\angle ABC+m\angle BCD\neq 180^\circ

So, the lines AB and CD are not parallel to each other.

Therefore, the intersection of lines AB and CD is possible.
