Answer:
I believe D is the answer
Step-by-step explanation:
how I find the slope it by looking at the y-axis and what hits directly on that line. you can see that 3 hits directly on that line so the b in y=mx+b is three which is your starting point. then you follow the line and see where it hits directly on a point. then count the blocks. remember that it's rise over run so that's y over x. so you go down five and over one. since you go down five it's negative. the negative is only added onto the five not the one. and since it's five over one, you don't need to put the over one, it's just automatically there. hope this helps! good luck!

Ashley is making trail mix.The ratio of peanuts to raisins in one portion is 5:9. Create a ratio table to find out how many peanuts and raisins you will need if you make 7 portions and 12 portions
The number of peanuts and raisins for 7 portions is 35 and 63 respectively.
What is the ratio?The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.
Given that, the ratio of peanuts to raisins in one portion is 5:9.
Number of peanuts and raisins you will need if you make 7 portions and 12 portions.
Now, 5×7 : 9×7
35:63
Here, 5×12 : 9×12
60 : 108
Therefore, the number of peanuts and raisins for 7 portions is 35 and 63 respectively.

Write a situation about today's sales for the following systems of equations and then determine how much of each menu item you sold e + f = 48 and e = 3f
Answer:
3x48+48 = 192
3x48= 144
144+48= 192
There has been sold 12 items of f and 36 items of e in the system.
What is a system of equations?A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
We are Given the system of equation:
(1) e + f = 48
(2) e = 3f
Then Substituting e=3f into e + f=48:
3f + f = 48
Adding similar terms:
4f = 48
Dividing both sides by 4:
f = 48/4
Simplifying:
f = 12
Replacing;
f=12 in e + f =48
e + 12 = 48
Now Subtracting -12 to both sides:
e = 48 - 12
e = 36
Thus There has been sold 12 items of f and 36 items of e.

What is the solution of 5y + 2 = 42?
The graph below shows the solution to which system of inequalities
Answer:
C. y </ 3/4x +10 and y<l -1/2x - 3
Step-by-step explanation:
Basically first do process of elimination with your focus on one equation
for example :: ( >l is greater then or equal to and <l is lease then or equal to)
focus -> y >l 3/4x + 10
1) determine which line has the y-intercept of positive 10
2) is the line dotted or straight? dotted line = > or < while straight line = >l or <l
this should get rid of B and D now
3) remember this = if the slope is - then the shaded portion would be the way that the less then sign is pointing
( y <l -4x then the shaded portion would be on the left side )
remember again = if the slope is + then the shaded portion would be the way that the greater then sign is pointing
( y <l 4x then the shaded portion would be on the right side )
so the line that we are focused on would have the right side shaded which means that it would be a <l ,so the answer would be C
hope this helped you understand how to solve these a bit better!

The ratio of adult to children is 5:2, There are 35 adults at the museum, how many children are there
Answer:
14 children
Step-by-step explanation:
If we know the ration, and we are given the adults, we can set up a proportion in order to solve for the amount of children there are.
5:2=35:x
5x=35*2
5x=70
x=14
There are 14 children
A triangle has a base of 18.1 kilometres and a height of 17.4 kilometres. What is the area?
Answer:
157.47km²
Step-by-step explanation:
Given the following
base of 18.1 kilometres
height of 17.4 kilometres
Area of the triangle = 1/2 * base * height
Area of the triangle = 1/2 * 18.1 * 17.4
Area of the triangle = 314.94/2
Area of the triangle = 157.47km²
Hence the area of the triangle is 157.47km²
Rita is designing a building shaped like a pyramid that's cut off in a plane parallel to its base (this is called a truncated pyramid). The building has a 64×64 m end text square base and is 36 m tall. The cut off section has an a16×16m square base and is 12 m tall. What is the volume of the building? Round to the nearest cubic meter.
Answer:
64,512 m3
Step-by-step explanation:
3 1
(base area)(height) = 3 1
(64⋅64)(48) =65,536
The volume of the building is 64512 cubic meters if the pyramid that's cut off in a plane parallel to its base.
What is a right square pyramid?In geometry, it is defined as the shape having a square base with equal sides length and all the vertex of the squares joints at the top which is perpendicular to the center of the square.
We know volume for the right square pyramid is given by:
[tex]\rm V= \frac{1}{3} b\times h[/tex]
Volume for the cut off portion:
[tex]\rm v = \dfrac{1}{3}\times16\times16\times12[/tex]
v = 1024 cubic meters
Volume for the completer pyramid"
[tex]\rm V=\dfrac{1}{3}\times64\times64\times48[/tex]
V = 65536 cubic meters
Volume of the building = 65536 - 1024
= 64512 cubic meters
Thus, the volume of the building is 64512 cubic meters if the pyramid that's cut off in a plane parallel to its base.

Ten players on Michelle's soccer team were asked if they will attend a soccer camp this summer and 7 said yes. There are 20 players on the team in all.
Write a pair of equivalent fractions that could be used to determine the number of players that will attend camp this summer.
How many players on Michelle's soccer team will attend a soccer camp this summer?
s is inversely proportional to t
When s = 0.5, t = 7
Work out s when t = 0.8
Given:
s is inversely proportional to t.
When s = 0.5, t = 7.
To find:
The value of s when t=0.8.
Solution:
s is inversely proportional to t.
[tex]s\propto \dfrac{1}{t}[/tex]
[tex]s=\dfrac{k}{t}[/tex] ...(i)
Where, k is the constant of proportionality.
Putting s=0.5 and t=7, we get
[tex]0.5=\dfrac{k}{7}[/tex]
[tex]0.5\times 7=k[/tex]
[tex]3.5=k[/tex]
Putting k=3.5 in (i), we get
[tex]s=\dfrac{3.5}{t}[/tex]
This is the equation of proportionality.
Putting t=0.8, we get
[tex]s=\dfrac{3.5}{0.8}[/tex]
[tex]s=4.375 [/tex]
Therefore, the value of s is 4.375 when t=0.8.
