Emma is making a snack mix of pretzels and peanuts. For every batch, she uses 2 thirds cup of peanuts and 3 u 2 , 1 half cups of pretzels. Use the ratio of pretzels to peanuts to find the constant of proportionality. Write an equation that relates the amounts of pretzels and peanuts in the snack mix.
Answer:
Explanation:
So the equation it's asking you to do is like y=kx ,
so your k is 2/3.
y=2/3x
Then for x it's 3 1/2.
y= 2/3(3 1/2)
now your "y" is any variable to hold the other too.
Hope this helped!

As a part of raising funds for an orphanage,you received $120.50 and wanted to split the money into
groups of food items; clothes and story books .
a)If you want the same amount for each group, how much money will you put into each group?
b)Imagine if you want to save same amount of the money for stationary items, then how will you split the money into various groups?Justify
c)If you receive an extra money of $9.50 from people, then how much will be saved for each group?(Include all the groups)
Answer:
a) there are three groups here
total cash = $120.50
each group takes = $120.50 / 3
each group have = $40.17
b) Total no of groups = 4
Total cash = $120.50
each group takes = $120.50 / 4
Each group have = $30.13
c) Total group =4
Total cash = $120.50 + $9.50
=$130
each group have = $130 / 4

Which 2 of the following statements are TRUE about the Y-INTERCEPT of this line? Select the TWO statements that are accurate.
A.
The y-intercept is 0.
B.
The y-intercept is 10.
C.
The y-intercept tells me that they paid the babysitter $20 to buy her lunch.
D.
The y-intercept tells me that they paid the babysitter $10 to buy her lunch.
The y-intercept, which represents the point the graph crosses the y-axis, is the point where x = 0, or the usual start of a time based function
The true statements about the y-intercept are;
B. The y-intercept is 10
D. The y-intercept tells me that they paid the babysitter $10 to buy her lunch
Reasons:
The points on the graph are;
[tex]\begin{array}{|c|cc|} \mathbf{Time }&&\mathbf{Cost}\\0&&10\\1&&20\\2&&30\\3&&40\\4&&50\\5&&60\end{array}\right][/tex]
The slope of the graph is therefore; [tex]\dfrac{60 - 50}{5 - 4} = 10[/tex]
The equation of the graph is y - 60 = 10·(x - 5)
y = 10·x - 50 + 60 = 10·x + 10
y = 10·x + 10The y-intercept is give by the point where the x-value is zero
At the start when x = 0, the amount paid to the baby sitter is y = 10×0 + 10 = 10
Therefore, the y-intercept which is $10, represent the amount the family
paid to the babysitter at the start for her lunch
The correct statements are therefore;
Option B; The y-intercept = 10
Option D; The y-intercept indicates the amount given to the babysitter for
her lunch

Find the zeros of f (x) = 8x^2 - 1.
The zeros are x = ___and x___
Answer:
x=[tex]\sqrt{2}[/tex]/4 and x=-[tex]\sqrt{2}[/tex]/4
Step-by-step explanation:
One method of solving is using the Quadratic Formula: -b ±[tex]\sqrt{b^{2}-4ac }[/tex]/2a, with a=8, b=0, and c=-1.
After plugging these values in you get -0±[tex]\sqrt{0^2-(4*8*-1)}[/tex]/2*8
After simplifying you get ±[tex]\sqrt{32}[/tex]/16
Because 32 is 2^5, you can simplify it to 4[tex]\sqrt{2}[/tex], which makes the equation ±4[tex]\sqrt{2}[/tex]/16, or ±[tex]\sqrt{2}[/tex]/4.

As shown on the diagram below ABC ~ DEF, AB=7x, BC=4, DE=7 and EF=x what is the length of AB?
==========================================================
Explanation:
We're told that [tex]\triangle ABC \sim \triangle DE F[/tex] which means triangle ABC is similar to triangle DEF. The order of the letters is important as you'll see in the next two paragraphs.
AB and DE are the first two letters of ABC and DEF respectively. These two sides pair up as one corresponding pair. This forms the fraction AB/DE.
Through similar logic, we get the fraction BC/EF. We have BC and EF as the last two letters of ABC and DEF respectively. This fraction is equal to the previous fraction we set up (due to similar triangles having equal proportions).
Once again, the order of the letters matters to tell us how the sides and angles pair up together.
-----------------
In short, the key takeaway from that last section is that we can form this equation:
AB/DE = BC/EF
From here, we apply substitution and solve for x
So,
AB/DE = BC/EF
7x/7 = 4/x
7x*x = 7*4 .... cross multiplication
7x^2 = 28
x^2 = 28/7
x^2 = 4
x = sqrt(4)
x = 2
We only consider the positive square root because x is some side length. Negative x values are not allowed.
To wrap things up, use that x value to find AB
AB = 7x = 7*2 = 14

6) Candace Parker bought some new furniture for her house. Tax was included in the price
of the furniture. She bought a chair for 213 dollars, a couch for $812.50, and a television
for $499.99. If she left a 15% tip on the final price of all the furniture how much would
she have paid in total for the furniture and the tip?
ning Carmelo Anthony
Answer:
$1,754,31
Step-by-step explanation:
Furniture = $213 + $812.50 + $499.99 = $1,525.49
15% * $1,525.49 = $228.82
Total = $1,525.49 + $228.82 = $1,754,31

Help stuck on question number 9
Answer:
y=4x-4
Step-by-step explanation:
You know that a line perpendicular to the equation (y= -1/4x-14) would have an opposite reciprocal slope.
The slope from the given equation is -1/4x. Take the opposite reciprocal and you get 4/1x or 4x as your slope.
Now use the point-slope formula to find your b value.
(y-y1)=m(x-x1)
m= 4
Plug in (3,8) for x and y, and solve.
(y-8)= 4(x-3)
y-8= 4x -12
y=4x-4
