<h3>Answer:   20 hours</h3>

=========================================

One way to solve

1 car = 20 minutes

3*(1 car) = 3*(20 minutes) multiply both sides by 3

3 cars = 60 minutes

3 cars = 1 hour

20*(3 cars) = 20*(1 hour) ... multiply both sides by 20

60 cars = 20 hours

-------------------

Another way to solve

(1 car)/(20 minutes) = (60 cars)/(x minutes)

1/20 = 60/x

1*x = 20*60 ... cross multiply

x = 1200 minutes

x = (1200 min)*( (1 hr)/(60 min) )

x = (1200/60) hr

x = 20 hours

<h3>Answer: Choice D</h3>

Domain: {-3, -1, 2, 4, 6}  

Range: {-2, 1, 2, 4, 6}

===========================================

Explanation:

The domain is the set of possible x values of a relation or function. To form the domain, we just list out the x coordinates of each point

Point A is located at (-3, 4) so the x coordinate x = -3 is part of the domain

Point B is at (-1,1) meaning x = -1 is also part of the domain

And so on. Doing this for all five points leads to the list of x coordinates {-3,-1,2,4,6} which is the domain.

--------------------

The range is a similar story, but we look at the y coordinates now. Point A has y coordinate 4, so y = 4 is part of the range.

Point B has y coordinate y = 1, so that is also part of the range.

The range is {-2, 1, 2, 4, 6} representing all of the possible y values of this relation.

With any set, the order does not matter. Though convention is to list the items from smallest to largest.

Estimate the difference of the decimals below by rounding to the nearest whole number. 23.827
iragen [17]

Step-by-step explanation:

The key rule is: to round up the number one digit to the left has to be the number 5 or more, else it rounds down.

23.827 rounds up because the 8 is more than 5.

1.218 rounds down because 2 is less than 5.

24-1= 23

Step-by-step explanation:

After 3 hours , 4² mold spores are growing.

After 6 hours , 4³ mold spores are growing.

After 9 hours , 4⁴ mold spores are growing.

After 12 hours , 4⁵ mold spores are growing.

It means in every 3 hours , 4 new spores form and grow from each pre-existing spore.

⇒ After 15 hours , 4⁶ mold spores are growing.

⇒ After 18 hours , 4⁷ mold spores are growing.

⇒ After 21 hours , 4⁸ = 65536 mold spores are growing
