Answer:
Store B offers the better buy. The difference in Unit cost is 5 cents or $0.05
Step-by-step explanation:
First find the costs per tuna. In Store A: 8 cans cost $7.20. To find the cost of 1 can you have to do $7.20/8 which is 90 cents or $0.90In store B; 6 cans cost $5.10. To find the cost of 1 can do $5.10/6 which is 85 cents or $0.85.Therefore store B is cheaper, and to find the difference cost: Do the larger cost minus the smaller: 90 cents-85 cents= 5 cents or $0.05 as the difference cost

Find x & y so that quadrilateral is a parallelogram. (Look at image)
Answer:
x = 20° and y = 12°
Step-by-step explanation:
3y + 15° = 5y - 9° ( being opposite angles of parallelogram)
5y - 3y = 15° + 9°
2y = 24°
y = 24° / 2
y = 12°
Now
5x + 29° = 7x - 11° ( being opposite angles of parallelogram)
7x - 5x = 29° + 11°
2x = 40°
x = 40° / 2
x = 20°

She earns $50 per week working at the stables and wonders how many weeks it will take to earn enough for a pony of her own. Show the relationship between the number of weeks (W) and Sadie’s savings (S) using an expression.
Answer:
It will take her 10.5 weeks.
Expression: 50w + 75
Find the value of x. Show your work congruent triangles
Answer:
x = 8
Step-by-step explanation:
We have a given triangle with two interior angles which are x + 23 and 80°. The third angle of the triangle would be equal to 4x + 17. This is because vertical angles are congruent.
Thus:
(x + 23) + 80 + (4x + 17) = 180
x + 23 + 80 + 4x + 17 = 180
5x + 120 = 180
Subtract - 120 both sides
5x = 180 - 120
5x = 40
Divide both sides by 5
x = 8
Find the value of x in the triangle shown.

In one study on the effect of argan oil on wrinkles, 125 subjects who acknowledged being long-time argan oil users had their wrinkles compared with those of 125 people who had never used argan oil. In a second study, 75 subjects were chosen randomly to use argan oil and 75 were chosen to use a placebo. Identify the types of studies performed. (4 points)
Answer: The first study was an observational study whereas the second was a controlled experiment.
Step-by-step explanation:
A study that record the characteristics of a population by studying individuals in a sample, but does not manipulate variables of interest is known as an operational study. Like in the first study only effects have been noted.
A controlled experiment is an experiment where the variable of interest is directly manipulated by a scientist, in order to test a single variable at a time.
Like in the second study, the subjects were under the control of the experimenter, to test the effect of oil.
The first study was an observational study whereas the second was a controlled experiment.

Step-by-step explanation:
the cost for a company to produce a part for d days is represented by the function f(d)=275d+12,950 what does the value 12,950 represent in this situation?
A.) Each day the total cost increases by $12,950
B.) The initial cost is $12,950
C.) Each day the total cost decreases by $12,950
D.) The total cost to produce a part for d days is $12,950
Answer:
B.) The initial cost is $12,950
Step-by-step explanation:
Given that:
[tex]f(d)=275d+12,950[/tex]
is the function to represent the cost for a company for the production of a part for [tex]d[/tex] number of days.
To find:
What does the value 12,950 represent in the above cost function.
Solution:
The given function contains two parts:
1. One part is multiple of [tex]d[/tex] and
2. Second part is a constant.
Here, [tex]d[/tex] is the number of days.
As [tex]d[/tex] changes, the value also changes but the constant part remains the same.
Therefore, we can conclude that the initial cost for the company is $12,950.
The answer is:
B.) The initial cost is $12,950
Answer: the initial cost is $12,950

Answer:
392?
Step-by-step explanation:
h = 4x and x= 3t write h in terms of t
Answer:
h = 12t
Step-by-step explanation:
Its given that x = 3t.
Also its given that h = 4x
Substituting the value of x gives =
h = 4(3t) = 4 × 3t = 12t
Prove the following statements: (a) For every integer x, if x is even, then for every integer y, xy is even. (b) For every integer x and for every integer y, if x is odd and y is odd then x y is even. (c) For every integer x, if x is odd then x 3 is odd.
Answer and Step-by-step explanation:
(a) Given that x and y is even, we want to prove that xy is also even.
For x and y to be even, x and y have to be a multiple of 2. Let x = 2k and y = 2p where k and p are real numbers. xy = 2k x 2p = 4kp = 2(2kp). The product is a multiple of 2, this means the number is also even. Hence xy is even when x and y are even.
(b) in reality, if an odd number multiplies and odd number, the result is also an odd number. Therefore, the question is wrong. I assume they wanted to ask for the proof that the product is also odd. If that's the case, then this is the proof:
Given that x and y are odd, we want to prove that xy is odd. For x and y to be odd, they have to be multiples of 2 with 1 added to it. Therefore, suppose x = 2k + 1 and y = 2p + 1 then xy = (2k + 1)(2p + 1) = 4kp + 2k + 2p + 1 = 2(kp + k + p) + 1. Let kp + k + p = q, then we have 2q + 1 which is also odd.
(c) Given that x is odd we want to prove that 3x is also odd. Firstly, we've proven above that xy is odd if x and y are odd. 3 is an odd number and we are told that x is odd. Therefore it follows from the second proof that 3x is also odd.

Step-by-step explanation:
11a^3−4a^2−14a−7
Answer:
11a³-4a²-14a-7
(The light blue/green one)
Step-by-step explanation:
We'll need to combine like terms (terms with the same variables and exponents)
(4a³-8a-4a²)+(7a³-7-6a)
add/subtract
we'll keep -4a² and -7 as is as there aren't any other terms like them
11a³-14a-4a²-7
put into standard form:
11a²-4a²-14a-7
(The light blue/Green one)

Multiply and simplify: –3x2y2 • x4
–3x5y2
9x5y2
–3x6y2
–3x5y6
Answer:
Multiplying and simplifying the term [tex]-3x^2y^2 \:.\: x^4[/tex] we get [tex]\mathbf{-3x^6y^2}[/tex]
Option C is correct option.
Step-by-step explanation:
We need to multiply and simplify: [tex]-3x^2y^2 \:.\: x^4[/tex]
Simplifying the term:
[tex]-3x^2y^2 \:.\: x^4[/tex]
While multiplying, the variables with same bases are multiplied: [tex]a^m\:.\:a^n=a^{m+n}[/tex]
In the given question only x^2 and x^4 are variables with same bases, So we get:
[tex]=-3(x^{2+4})y^2\\=-3x^6y^2[/tex]
So, multiplying and simplifying the term [tex]-3x^2y^2 \:.\: x^4[/tex] we get [tex]\mathbf{-3x^6y^2}[/tex]
Option C is correct option.
