At the local dairy farm, Kareem buys a 32-oz container of yogurt for $2.56. Jonah buys a 6-oz container of yogurt for $0.48. Are the cost, y, in dollars and the amount of yogurt, x, proportional? Explain. Write an equation to represent this relationship.
I need the answer asap plsssssssss ty
Answer:
Yes, y = .08x
Step-by-step explanation:
Yes, because if you divide 2.56 by 32 you get .08.
If you multiply .08*6 = .48.
The equation would be y = .08x
If y is the cost and x is the amount of yogurt then this equation makes sense.
Check 32oz
y = .08(32)
y = 2.56

−7x + 25 = 48 Step 1: −7x + 25 − 25 = 48 − 25 Step 2: −7x = 23 Step 3: negative seven times x over seven = twenty-three over seven Step 4: x = twenty-three over seven Step 1: He should have added 25 to each side. Step 1: He should have divided both sides by −7. Step 3: He should have divided both sides by −7. Step 3: He should have multiplied both sides by −7.
Answer:
Step 3: He should have divided both sides by −7
Step-by-step explanation:
Incorrect calculation
−7x + 25 = 48
Step 1: −7x + 25 − 25 = 48 − 25 Step 2: −7x = 23
Step 3: negative seven times x over seven = twenty-three over seven
-7*x/7 = 23/7
-7x/7 = 23/7
Step 4: x = twenty-three over seven
Correct calculation
−7x + 25 = 48
Step 1: −7x + 25 − 25 = 48 − 25 Step 2: −7x = 23
Step 3: negative seven times x over seven = twenty-three over seven
-7*x/-7 = 23/-7
-7x/-7 = 23/-7
Step 4: x = twenty-three over negative seven
x = -23/7
Lucy can buy a pair of shoes from 4 different retailers. Which is the best buy?A.Online Shoes for $32, plus a sales tax of 8% and shipping and handling costs of $6B.From the Best Buy Shoes catalog for $35 plus 8% sales tax and free shipping and handling.C.Local shoe store for $38 with 15% discount and 8% sales taxD.Local shoestore for $40 with 25% discount and 8% sales tax
9514 1404 393
Answer:
D. $40 with 25% discount
Step-by-step explanation:
All of the options have 8% sales tax, so that is not important to choosing the best deal.
The store with the lowest price after discount is D (local shoe store #2), as the discount brings the price down to $30 before tax.
The price at store C (local shoe store #1) will be 15% less than $38.00, so about $5.70 less. That is not as low a price as at store D.
The best buy is had at store D.
__
In the spreadsheet, we have multiplied the base price by (1+discount) then added shipping. That total is multiplied by (1+tax rate).

PLZ HELP I WILL GIVE 20 POINTS WHOEVER ANSWERS FIRST:
Answer:
-2
Step-by-step explanation:
So to find slope you just subtract y^1 - y^2 and divide it by x^1 - x^2
The first point is (2, 1)
The second is (0, 5)
1 is our y^1 and 5 is our y^2
1 - 5 = -4
2 is our x^1 and 0 is our x^2
2 - 0 = 2
So our slope is -4/2, reduced its -2

Elise doesn't like sorbit, so she omits that ingredient and adds 5 percent to each of the other ingredients. How many cups of punch will she have if she uses 6 cups of orange juice?
Answer: 20
Step-by-step explanation:
From the question, to make the punch recipe, the following are needed:
Ginger Ale - 40%
Orange Juice - 25%
Pineapple juice - 20%
Sorbet - 15%
Since we are told that Elise doesn't like sorbit, so she omits that ingredient and adds 5 percent to each of the other ingredients. The the new percent will be:
Ginger Ale - 40% + 5% = 45%
Orange Juice - 25% + 5% = 30%
Pineapple juice - 20% + 5% = 25%
Sorbet - 15% - 15% = 0
To get the total cups of punch that'll be used, let it be represented by y. Therefore,
30% of y = 6
30/100 × y = 6
0.3 × y = 6
0.3y = 6
y = 6/0.3
y = 20
Therefore, she'll have 20 cups of punch.
Given the exponential function [tex]f(x) = -2(0.8)^x[/tex], what is the value of f(x) when x =0?
Work Shown:
[tex]f(x) = -2(0.8)^x\\\\f(0) = -2(0.8)^0\\\\f(0) = -2(1)\\\\f(0) = -2\\\\[/tex]
In the third step, I used the idea that [tex]x^0 = 1[/tex] where x is any nonzero number.

A train covers 165 km in 1.5 hours. How far will the train travel in 2.2 hours if it maintains the same speed?
Answer:
242
Step-by-step explanation:
165 ÷ 15 = 110
110 × 2.2 = 242
The distance that trains travel in 2.2 hours with the same ratio or same speed will be 242 km.
What are the ratio and proportion?The ratio is the division of the two numbers.
For example, a/b, where a will be the numerator and b will be the denominator.
Proportion is the relation of a variable with another. It could be direct or inverse.
As per the given,
A train covers 165 km in 1.5 hours.
The ratio of distance covered to the number of hours is 165/1.5.
Let's say in 2.2-hour train travel x number of km.
The ratio of distance covered to the number of hours x/2.2
Both ratios must be the same,
x/2.2 = 165/1.5
x = 110 x 2.2 = 242 km
Hence "The distance that trains travel in 2.2 hours with the same ratio or same speed will be 242 km".

It takes 16 beads to make 4 bracelets. What is the constant of proportionality that relates the number of bracelets made, y, to the number of beads used, x?
Answer:
4
Step-by-step explanation:
Given that:
Number of beads used to make 4 bracelets = 16
Number of bracelets made = [tex]y[/tex]
Number of beads used = [tex]x[/tex]
To find:
The constant of proportionality = ?
Solution:
Number of bracelets made is proportional to Number of beads.
i.e.
[tex]y \propto x[/tex]
OR
[tex]y=k\times x[/tex]
Where [tex]k[/tex] is the constant of proportionality.
We are given that:
when [tex]x = 12, y = 4[/tex]
Putting the values in the above equation:
[tex]4 = k \times 16\\\Rightarrow \bold{k = 4}[/tex]
Therefore, the constant of proportionality is 4.
Line q has a slope of 4 and line r has a slope of –1/4.

Complete each of the following statements given z = 1 - 2i and w = -3 + 5i
The answers would be z + w = -2 + 3i, z - w = 4 - 7i, and w - z = 4 + 7i after adding and subtracting two complex numbers.
What is a complex number?It is defined as the number which can be written as x+iy where x is the real number or real part of the complex number and y is the imaginary part of the complex number and i is the iota which is nothing but a square root of -1.
It is given that:
The complex numbers are:
z = 1 - 2i and w = -3 + 5i
z + w = 1 - 2i - 3 + 5i
z + w = -2 + 3i
z - w = 1 - 2i + 3 - 5i
z - w = 4 - 7i
w - z = 4 + 7i
Thus, the answers would be z + w = -2 + 3i, z - w = 4 - 7i, and w - z = 4 + 7i after adding and subtracting two complex numbers.

You are given a various set of values: xbar = 12 ybar = 16 r = .46 Sy = 18 Sx = 6 Find a and b, then write them as an equation for a line. b = a = yhat =
Answer:
Slope, b = 1.38 ; intercept, a = - 0.56 ;
Y = - 0.56 + 1.38x
Step-by-step explanation:
Given that :
xbar = 12
ybar = 16
r = .46
Sy = 18
Sx = 6
The equation of a line can be expressed as :
Y = a + bx
Where ;
a = intercept ; b = slope ; x = independent variable ; y = dependent variable
The slope b ; can be obtained using the relation :
b = r(Sy / Sx)
= 0.46(18/6)
= 0.46(3)
= 1.38
The intercept a, can be obtained using the relation :
Ybar - b(Xbar)
16 - 1.38(12)
16 - 16.56
a = - 0.56
Hence ;
Slope, b = 1.38 ; intercept, a = - 0.56
Th equation of the line will be :
Y = - 0.56 + 1.38x
