Answer:
-3/2
Step-by-step explanation:
Perpendicular lines have negative reciprocal slopes. That means that it's the reciprocal, but with the opposite sign. The slope of a line perpendicular to a line with slope 2/3 would be -3/2. Here's how to figure it out:
Start with the slope: 2/3
Flip the fraction to find the reciprocal : 3/2
The sign has to be changed! So the negative reciprocal is -3/2.

Answer:
84
Step-by-step explanation:
140% of 60 = 60 times 140% = 60 × 1.4 = 84
Volume of a cone = (1/3) * Area of Base * height
144 * 3 / 9 = Area of Base
Area of the Base = 48
Answer:
A = 800( 1.075)^(t)
Step-by-step explanation:
The equation for interest is
A = p (1+r/n) ^ nt where p is the principle, r is the interest rate, n is the number of times per year and t is the years
A = 800( 1+ .075/1)^(1*t)
A = 800( 1.075)^(t)
