70% of the members voted for Jina.

Step-by-step explanation:

votes : members

  28   :      40

  70   :      100

70% of the members voted for Jina.

70%

Step-by-step explanation:

To find the percentage, turn 28/40 into a fraction:

28

40

Then, keep simplifying it, or dividing it by the GCF.

28 14 7

> >

40 20 10

7/10 in a percentage is 70 percent since 7/10 can turn into 70/100

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

48 / 6 = x

in this case, x will equal the amount of money in each card!

x therefore will be 8.

trent had $8 in each birthday card.
