Aliza needs to run at a rate faster than 8.8 feet per second in order to exceed her fastest time in a race. After running for 15

Answer:

$120.

Step-by-step breakdown:

Libby sold $60 worth of vegetables at the farmer's market.

Jess sold 3/4 of what Libby sold, so let's calculate that: 3/4 of 60.

Thus, Jess made $45.

Now, Stephanie sold one-third of Jess's total, necessitating the calculation of one-third of 45.

This means Stephanie sold $15 worth of vegetables.

Putting together Libby's, Jess's, and Stephanie's sales, we arrive at the collective total earned by all three.

Consequently, their total sales amount to $120.

The equation of the perpendicular line can be identified by determining its slope and applying the given point within the standard formula.

Standard equation: y-y1 = m(x-x1)

m*m'=-1
where m' indicates the slope of the perpendicular line
m denotes the slope of the original line

m = -coefficient of x/coefficient of y = -4/-3 = 4/3
m' = -3/4

Substituting the point (3, -2):
y+2 = -3/4*(x-3)
4y+8 = -3x+9

Thus, the equation of the perpendicular line is: 3x+4y-1=0
