Answer:
There is a difference between FRACTION and PROPORTION.
Explanation of fraction:
On a card board sheet draw a square or rectangle or any simple shape of your choice. Divide your preferred shape into 4 equal parts. One portion or one part of the divided shape is 1/4. Three (3 ) parts of the divided shape equal 3/4. Also if the shape is divided into twenty (20). One (1) part is 1/20, sixteen(16) parts equal 16/20.
Explanation of Proportion:
If an item is shared in a proportion of 3:4,it means that A gets 3/(3+4) of what is to be shared , that is 3/7 of the bulk item to be shared. B gets 4/(3+4) of what is to be shared, that is 4/7 of the bulk item to be shared.
Also if an item is shared in a proportion of 16:20 , A gets 16/(16+20)=16/36 of Bulk item while B gets 20/(16+20)= 20/36 of the Bulk item being shared.
In effect Fractions and Proportions are related but different.
A ball falls from the top of a building. When it strikes the ground its velocity is 10 m/s. It took 5 seconds to fall. What is its acceleration? _____ m/s2
Answer:
a = 2 m/s²
Step-by-step explanation:
[tex]a = \frac{v-u}{t}[/tex]
where v is the final velocity, u is the initial velocity, and t is the time it takes. the intial velocity is always 0 m/s. given the equation, we subsitute:
[tex]a = \frac{10m/s - 0 m/s}{5s}[/tex]
a = 10m/s ÷ 5s
a = 2 m/s²

What are the factors of the function represented by this graph?
A. (x − 4) and (x − 8)
B. (x − 4) and (x + 8)
C. (x + 4) and (x − 8)
D. (x + 4) and (x + 8)
The factors of the function represented by the graph are (x + 4) and (x - 8)
How to determine the factors of the function represented by the graph?From the question, we have the following parameters that can be used in our computation:
The graph
From the graph, we can see that:
The graph intersects with the x-axis at x = -4 and x = 8
So, we have
x = -4 and x = 8
Set the equations to 0
So, we have
x + 4 = 0 and x - 8 = 0
This means that the factors of the function represented by the graph are (x + 4) and (x - 8)

Select the correct days. Gina tracks the low temperatures for a city over six days. Identify the days colder than -1.75°F.
Answer:
[tex]Monday = -2.5F[/tex]
[tex]Tuesday = -1.9F[/tex]
Step-by-step explanation:
Given
See attachment
Required
Days colder than -1.75°F
From the attachment, we have:
[tex]Monday = -2.5F[/tex]
[tex]Tuesday = -1.9F[/tex]
[tex]Wednesday = 0F[/tex]
[tex]Thursday = -1.5F[/tex]
[tex]Friday = 0.5F[/tex]
Days with temperature less than -1.75°F are colder.
-2.5 and -1.9 are less than -1.75
So, we have:
[tex]Monday = -2.5F[/tex]
[tex]Tuesday = -1.9F[/tex]

what is the area of a square yards of a rectangle with a length of 9 yds and a width of 4 yds?
[tex]a = lw[/tex]
[tex]a = (9)(4)[/tex]
[tex]a = 36 \: {yds}^{2} [/tex]
Answer:
Here we can understand that the shape is a rectangle as length is not equal to width.
Area of the rectangle in square yards when length is 9 yds and width is 4 yds will be,
Area of Rectangle = LENGTH × WIDTH
⇒ 9*4
⇒ 36 sd yds
Thus the are will be 36 sd yds

Bir kutudaki kalemlerin sayısı, mavi renkli kalemlerin sayısından 48 fazladır. kutudaki kalemlerin sayısı, mavi kalem sayısının 9 katı olduğuna göre, kutuda kaç tane mavi kalem vardır
Answer:
6
Step-by-step explanation:
Mavi kalemlerin sayısına x diyoruz
Kutudaki kalemlerin sayısı mavi kalemlerin sayısından 48 fazlaymış yani x+48 kutudaki kalemlerdir.
Kutudaki kalemlerin sayısı mavi kalem sayısının 9 katı ise x+48=9x olur
Şimdi denklemi çözmemiz lazım sol taraftaki x sağ tarafa - x olarak geçer sağ tarafda 8x kalır yeni denklemimiz 48=8x olur
Her iki tarafı da bilinmeyenin yanındaki sayıya böleriz bunun sonucu da 6=x çıkar
Mavi kalemlere de x demiştik yani 6 adet mavi kalem vardır.
