Answer:

The unit rate would be gallons per minute.

Divide total gallons by total minutes:

42/8 = 5.25

Unit rate = 5.25 gallons per minute

B) The perimeter of the rectangle below is 42cm. Calculate thelengths of the sides by forming an equation and solving it.x-2x + 5

**Step-by-step explanation:**

**Answer:**

** 8 and 9**

**Step-by-step explanation:**

√64 = **8**

√81 = **9**

√74 falls inbetween those 2

8 and 9

8*8=64

9*9=81

74 is between those

8*8=64

9*9=81

74 is between those

Answer-44

You can turn both of the denominators ( bottom numbers on the fractions ) into 120 ( the whole number ) and the top numbers can be multiplied by how many times the denominators went into 120. Then add the top numbers which equals 76 and then 120-76=44. Hope that kinda helps !!

**Answer:**

x+ 0.5=3 this is the equation

**Step-by-step explanation:**

first you would subtract 0.5 on both sides. Then You have an answer of x=2.5

Hope this helped have a good day :D

**Answer:**

69 users.

**Step-by-step explanation:**

First, we need to calculate the amount of seconds in one day.

a) Each hour has 60 minutes and each minute has 60 seconds.

Therefore, one hour has (60)(60) = 3600 seconds.

b) Since the day has 24 hours, we are going to multiply the total amount of seconds per hour by 24.

3600 (24) = 86400 seconds per day.

c) Now that we have the amount of seconds per day, we are going to divide the total amount of users added each day by the amount of seconds per day.

6000000/86400 = 69.44 users per second.

Therefore, 69 users are added, on average, each second.

**Answer:**

**Step-by-step explanation:**

For this case we have the following expression:

(1)

And we want to find the value of ln K. If we apply natural log on both sides of the equation (1) we got:

Using the following property:

for x and y real numbers, x>0, y>0, then we have:

Now since the natural log and the exponentiation are inverse operations we have this:

And then the final expression for ln K is :
