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.

i really need help with this 6th grade work due today
5
Step-by-step explanation:
Length (L) = u
Breadth (b) = 6 mi
Perimeter (P) = 22 miles
Now we know
P = 2 (L+ b)
22 = 2 ( u + 6)
11 = u + 6
11 - 6 = u
u = 5
Answer:
u = 5
Step-by-step explanation:
The perimeter of a rectangle is all the sides added up.
The oppisite sides are parralel.
So the side across from 6 is all 6
6 + 6 = 12
The perimeter is 22 so you do
22 - 12 = 10
So 'u' equals 5 because you have to divide the number 10 by 2.

The lines represented by the equations y + 5/3x = -4 and 3y - 5x = 9 are
the same line
parallel
neither parrallel nor perpendicular
perpendicular
SOMEONE PLS HELP
Answer:
C. neither parallel nor perpendicularStep-by-step explanation:
Given lines:
y + 5/3x = -4 and 3y - 5x = 9To determine the relationship between the lines put them both into slope-intercept form and compare the slopes.
y + 5/3x = -4 ⇒ y = -5/3x - 43y - 5x = 9 ⇒ 3y = 5x + 9 ⇒ y = 5/3x + 3The slopes are different so the lines are neither parallel nor perpendicular.
Correct choice is C
Answer:
Neither parallel nor perpendicular
Step-by-step explanation:
If two lines are parallel, they share the same slope. If two lines have slopes that are opposite reciprocals of each other, then they are perpendicular. If it is the same line, then the two equations must be the same when converted into the same form. If none of these apply, then the line is neither of any these.
1) First, convert each equation into y = mx + b format, or slope-intercept form, to easily identify their slopes. Isolate y in both equations.
First equation:
[tex]y + \frac{5}{3} x = -4\\y = -\frac{5}{3} x-4[/tex]
Second equation:
[tex]3y - 5x = 9 \\3y = 5x + 9 \\y = \frac{5}{3} x + 3[/tex]
2) In slope-intercept format, the coefficient of the x term, or m, represents the slope. Thus, the slope of the first equation is [tex]-\frac{5}{3}[/tex] while the slope of the second equation is [tex]\frac{5}{3}[/tex]. The slopes are not the same, nor are they opposite reciprocals of each other. The equations are not the same either. Therefore, they are neither parallel nor perpendicular.
Nola was selling tickets at the high school dance. At the end of the evening she picked up the cash box and noticed a dollar lying next to it. She said, "I wonder whether the dollar belongs inside the cash box or not." The price of tickets for the dance was 1 ticket for
Answer:
The $1 belongs to the cash box
Step-by-step explanation:
Given
See attachment for complete question
Required
Determine if the $1 belongs to the cash box or not
Represent singles with s and couples with c.
From the attachment, we have:
[tex]s + c = 47[/tex] --- total attendance
[tex]5s + 4c =200[/tex] --- ticket sold
Solve for s and c.
Make s the subject in (1)
[tex]s = 47-c[/tex]
Substitute 47 - c for s in (2)
[tex]5(47 - c) + 4c = 200[/tex]
Open bracket
[tex]235 - 5c + 4c = 200[/tex]
[tex]235 - c = 200[/tex]
[tex]c = 235 - 200[/tex]
[tex]c = 35[/tex]
This means that the total individual which makes up the couples are 35. This is not possible because couples are in 2's and the total should be an even number.
So, we can conclude that the $1 belongs to the cash box

Find the slope of a line parallel to each given line. y=-5/3x+5
Answer:
m= -5/3
Step-by-step explanation:
M= slope
To find slope, you do y= mx + b
Answer:
[tex]\boxed {\boxed {\sf m= -\frac{5}{3}}}[/tex]
Step-by-step explanation:
First, identify the slope of the line given.
[tex]y= -\frac{5}{3}x+5[/tex]
This line is in slope-intercept form or y=mx+b where m is the slope and b is the y-intercept. The number being multiplied by x is the slope. The number being added or subtracted is the y-intercept.
-5/3 is the coefficient to x (-5/3 and x are being multiplied). So, the slope must be -5/3.
Next, remember that parallel lines have equal slopes. If the line is parallel to y= -5/3x+5, the slope must also be -5/3.
