A.the rise of reptiles and flowering plants
B. the rise of mammals and swimming mammals
C. the ice ages and the rise of humans
D. the rise of dinosaurs and other reptiles
The Quaternary period is best known for the ice ages and the rise of humans.
What is the quaternary period?The numerous cycles of glacial expansion and retreat, the extinction of several species of big animals and birds, and the spread of humans are all associated with the Quaternary Period.
Due to the existence of at least one permanent ice sheet (Antarctica), the whole Quaternary Period, including the present, is referred to as an ice age; yet, the Pleistocene Epoch was usually drier and colder than the current period.
The Holocene is the most recent of the geochronological time divisions that make up the quaternary period, which began around 2.6 million years ago with the commencement of the Northern Hemisphere glacial (Zalasiewicz et al., 2015). Glacier deposits and proof of glacial erosion are the Quaternary's most distinctive features at middle and high latitudes. The main characteristic of high mountains like the Alps, Himalayas, Andes, and Rockies is glacial erosion.

Shaggy earned 7.50 an hour plus an additional $100 in tips waiting tables last night. He earned more than $160 in all. Write an inequality to represent this situation and help you find the number of hours (h) he worked.
Answer
x>21.2
Step-by-step explanation:
7.55x+100>160:
subtract 100 on both sides to get:
7.55x>60:
divide 7.55 on both sides:
x>21.2 is your answer
Answer:
7.50h + 100 > 160
Step-by-step explanation:
7.50 is the hourly wage
h = hours he worked
add 100 once because it's his tips for the amount of time her worked
since he worked more than 160, you'll use the greater sign
then solve for h
h = 8 hours

Write an equation in point slope form that passes through the given point and has the given slope.
Point = (-1, -4)
Slope = 2
Answer:
y+4=2(x+1)
Step-by-step explanation:
y-y1=m(x-x1)
y-(-4)=2(x-(-1))
y+4=2(x+1)
Answer:
y+4=2(x+1)
Step-by-step explanation:
point slope form
(y-y1)=m(x-x1)
m: slope = 2
(x1,y1) = (-1,-4)
(y+4)=2(x+1)

Two fair dice are rolled at the same time. What is the probability that one die will show 3 and the other will show 4? A. 1/36
B. 1/18
C. 1/12
D. 1/6
Answer:
1/36
Step-by-step explanation:
There are 6 numbers on a die. You have a 1/6 chance of rolling a 3 and a 1/6 chance of rolling a 4. 1/6 times 1/6 = 1/36.
Enter the number that makes the equation true
Answer:
80
Step-by-step explanation:
First of all, before you do anything to compute the answer, you can see that there is (–13/100) on both sides of the equation. You can cancel them out, since they're the same thing.
Now, you're left with:
[tex]0.8 = \frac{}{100}[/tex]
This is also read as 0.8 is the same thing as [how many] hundredths.
You should know that 0.8 = eight tenths.
So if you move the decimal point right once, you'll get:
0.80
Which is also eighty hundredths.
Your answer would be:
[tex]0.8 = \frac{80}{100}[/tex]
which is 80.
To check your answer, you can also do:
80/100
Because the fraction bar can also be read as "divided by."
You will get 0.8.
