In this case,
Therefore,
Hence, the correct answer is (-1, 4) (option 3)
9 is what percent of 6 the answer is 150%
Answer:
There was a 48% increase from last year.
Step-by-step explanation:
Last year the debate club had 25 members. This year there are 37 members in the club. Estimate the percent change in the number of club members.
= (37 - 25) / 25
= -12 / 25
= 0.48 or 48%
There was a 48% increase from last year.
<u>check: </u>
25 * 1.48 = 37
Answer: 60°
Step-by-step explanation:
When a figure has a rotational symmetry, it maps onto itself under rotation about a point at the centre.
When an hexagon rotate onto itself,
the vertices must cover to vertices and from sides to sides. There are six angles in a hexagon and the sum of the angles is 360°. Therefore, each angle has a measure of 360°/6 is equal to 60°.
Rotating subsequently by 60 degree will rotate a hexagon onto itself. A hexagon has 6 rotations, that is, a hexagon has a rotational symmetry of 6 and at angle 60°, the hexagon will rotate onto itself.
