Olivia was reading about the Earth’s history. She grew interested in the Quaternary period in the Cenozoic era and studied it further. The Quaternary period is best known for which two major events?
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)

Before beginning voice lessons, Colin already knew how to sing 2 pieces, and he expects to
learn 2 new pieces during each week of lessons. How many weeks of lessons will Colin need
before he will be able to sing a total of 50 pieces?
Answer: Answer is 24 though
Answer:
24 weeks of lessons
Step-by-step explanation:
use y = mx + b
y = total pieces Colin can sing = 50
m = pieces learned each week of lessons = 2
x = number of weeks = ?
b = pieces colin knew before lessons = 2
50 = 2x + 2 (subtract 2 from both sides)
48 = 2x (divide both sides by 2)
x = 24 weeks

The Greatest Value of a country's paper money ever printed is 10 to the 8th power dollars. What is this amount written in standard form?
Answer: 1 × 10^8
Step-by-step explanation:
The standard form is written as:
= c × 10^n
For example if we are told to change 200 to standard form, it'll be:
200 = 2 × 10^2
Therefore, 10 to the 8th power in standard form will be:
= 1 × 10^8
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.

One tract of land contains 25 acres. An adjoining tract of land is 1 square mile. The owners agreed to sell for $1,500 per acre. What was the total price of the 2 lots?
Answer:
$997,500
Step-by-step explanation:
Tract 1 = 25 acres
Tract 2 = 1 square mile
Cost of land per acre = $1500
Number of acres per square mile = 640 acres
Total number fo acres :
(Tract 1 + Tract 2)
(25 + 640) acres
= 665 acres
Total cost :
665 * $1500
= $997,500
