Identify the percent of change as an increase or a decrease. 3/8 to 7/8. find the percent of change. round to the nearest tenth of a percent if necessary.

Percentage of change is increase .

The percentage of change is  133.3 % (Approx).

Step-by-step explanation:

Formula

As given

Clearly the fraction is increase .

Here

Put in the formula

Put in the formula

Perecntange = 133.3 % (Approx)

554.4

step-by-step explanation:

44*12.6=544.4

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.
