Area of the rectangle = L X W

Area of the rectangle = 4 X 2

Area of the rectangle = 8 inches

If the drawing is 1/5 of the actual air conditioning unit, then you multiply the reciprocal which is 5 times the area of the drawing. When you want to enlarge it has to be a whole number. When you want to reduce you multiply by a fraction.

So 8 inches X 5 = 40 inches is the actual area of the unit.

Kurt drives a total of 32 miles to and from work every day. He works 5 days a week. How many miles does Kurt drive in a week for
Naily [24]
Does Kurt drive 32 miles to work and 32 back home or does Kurt drive a combined total of 32 miles to and from work.

If he drive 32 miles to work and 32 home- Kurt would have driven a total of 64 miles each day. So if he works 5 days a week you would just use this simple equation: {64 x 5} which would get you 320 miles each week.

If he drives a combined total of 32 miles each day then you use this following equation: {32 x 5} which would get you 160 miles each week

A diver is standing on a platform 24 feet above the pool. He dives form the platform with an initial upward velocity of 8 feet p
Mazyrski [523]

Answer:

It should be t = 1.5 seconds  if your equation is  h(t)  = -16*t^2 + 8t + 24

Step-by-step explanation:

h(t)  = -16*t^2 + 8t + 24

We want  to solve for t when h(t) = 0.

This is a parabolic equation so basically we can use the quadratic formula to solve this.

h(t)  = -16*t^2 + 8t + 24

0 = h(t)  = -16*t^2 + 8t + 24

take out the 8

0 = -2t^2 + t + 3

0 = -2t*t  - 2t  + 3t + 3

0 = -2t * (t + 1)  +  3*( t + 1)

0 = (-2t + 3) * ( t + 1)

so time cannot be negative, so we choose  0 = (-2t + 3),   t = 3/2 seconds

or  t = 1.5 seconds

Answer:

Step-by-step explanation:

x = 1/4

y = -x = -1/4

x-y=\frac{1}{4}-(-\frac{1}{4})\\\\=\frac{1}{4}+\frac{1}{4}\\\\=\frac{1+1}{4}\\\\=\frac{2}{4}\\\\=\frac{1}{2}
