Answer:

Step-by-step explanation:

If two line 'm' and 'n' are parallel and a transversal line 't' i intersecting these lines at two distinct points,

Sum of interior consecutive angles should be 180°.

(Property of the angles formed between parallel lines and a transversal line)

Therefore, 114° + 64° = 180°

178° = 180°

Which is not true.

Therefore, lines 'm' and 'n' are not the parallel lines.

Kim picked 250 pounds of pears yesterday and 287 pounds of pears today. What is the percentage increase of

xxMikexx [17]

Given:

Kim picked 250 pounds of pears yesterday and 287 pounds of pears today.

To find:

The percentage increase of amount of pears picked by Kim.

Solution:

We know that,

$\%\text{ increase}=\dfrac{\text{New value - Initial value}}{\text{Initial value}}\times 100$

$\%\text{ increase}=\dfrac{287-250}{250}\times 100$

$\%\text{ increase}=\dfrac{37}{25}\times 10$

$\%\text{ increase}=\dfrac{370}{25}$

$\%\text{ increase}=14.8$

Therefore, the percentage increase of amount of pears picked by Kim is 14.8%.

Which of the following points is a vertex for the image produced by a dilation about the origin with a scale factor of 1/2?

MA_775_DIABLO [31]

Answer:

A (0,3)

Step-by-step explanation:

The given trapezoid has vertices:

(0,6), (7,12), (7,9) and (0,12).

We want to choose from the given options, a point that is a vertex for the image produced by a dilation about the origin with a scale factor of 1/2.

Note that the mapping for such a dilation is:

$(x,y)\to( \frac{1}{2} x, \frac{1}{2} y)$

This implies that:

$(0,6)\to(0,3)$

$(7,12)\to(3.5,6)$

$(7,9)\to(3.5,4.5)$

$(0,12)\to(0,6)$

Therefore correct choice is (0,3)
