Answer:

r =5 miles per hour

Step-by-step explanation:

rt = d

We want to solve for r

Divide each side by t

rt/t = d/t

r = d/t

We know the distance is 7.5 miles and the time is 1.5 hours

r = 7.5 miles / 1/5 hours

r =5 miles per hour

Answer:

The rate is 5 miles per hour

Step-by-step explanation:

First thing off we need to get r alone. We can do this by dividing both sides by t. Lets do so

rt/t=d/t

Simplfy

r=d/t

Now input the known value for d and t

r=7.5/1.5

Divide

r=5

The rate is 5 miles per hour

An adult takes 800 mg of ibuprofen. Each hour, the amount of ibuprofen in the person's
ss7ja [257]

Answer:

116.31468544 mg ibuprofen left

Step-by-step explanation:

Since there are 800 mg at the beginning and the system decreases by about 32% of the ibuprofen

After 1 hour

→ 800 - (800x32/100) = 800 - 256 = 544 mg ibuprofen left

After 2 hours

→ 544 - (544x32/100) = 544 - 174.08 = 369.92 mg ibuprofen left

After 3 hours

→ 369.92 - (369.92x32/100) = 369.92 - 118.3744 = 251.5456 mg ibuprofen left

After 4 hours

→ 251.5456 - (251.5456x32/100) = 251.5456 - 80.494592 = 171.051008 mg ibuprofen left

After 5 hours

→ 171.051008 - (171.051008x32/100) = 171.051008 - 54.73632256 = 116.31468544 mg ibuprofen left
