Using proportions, it is found that:
3. Due to the lower cost per pound, the twelve-pack is the better value.
4. Due to the lower cost per cup, the Pacific Coast Coffee is the better value.
5. Lettuce and Asparagus cost the same per pound.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.
For item 3, the cost per pound is the proportion of the cost by the weight, hence:
6 pack: 1.75/6 = $0.292 per pound.12 pack: 3/12 = $0.25 per pound.Due to the lower cost per pound, the twelve-pack is the better value.
For item 4, we follow the same procedure, hence:
Pacific: 12.88/80 = $0.161 per cup.Down South: 9/50 = $0.18 per cup.Due to the lower cost per cup, the Pacific Coast Coffee is the better value.
In item 5, we have that:
Lettuce: 8.75/3.5 = $2.5 per pound.Snap Peas: 11.25/3 = $3.75 per pound.Asparagus: 6.25/2.5 = $2.5 per pound.Lettuce and Asparagus cost the same per pound.

To reflect a graph, f(x) over the x-axis, you take -f(x). So if f(x)=x^2, then -f(x) is -x^2. Then g(x)=-x^2 is the reflection of your function f(x) over the x-axis.

Solve the given differential equation's particular solution when the curve passes through the point (a = 1, b = 1).
(b^2+7ab+16a^2)da+a^2db=0
Answers
The solution of the given differential equation is;
-1/(b/a + 4) = -㏑|a| - 1/5.
What is defined as the differential equation?A differential equation is a mathematical expression that contains one or even more functions and their derivatives. The function's derivatives characterize the rate of change in a function at a given point.The given differential equation is-
(b² + 7ab + 16a²)da + a²db = 0
Take da common from both;
b² + 7ab + 16a² + a²db/da = 0
The curve passes through the point (a = 1, b = 1).
As, the given differential eq is the homogeneous eq; we can use it as;
Put, b = va
Differentiate above applying product rule.
db/da = (dv/da)a + v
Substitute the value in the main equation;
(va)² + 7a(va) + 16a² + a²( (dv/da)a + v ) = 0
Dividing whole equation by a².
v² + 7v + 16 + (dv/da)a + v = 0
Further simplifying;
(dv/da)a = -(v² + 8v + 16)
(dv/da)a = -(v + 4)²
Bring similar variable together;
dv/(v + 4)² = -da/a
Integrating the equation;
-1/(v + 4) = -㏑|a| + C ; c is the integration constant.
Substitute again the values of v;
-1/(b/a + 4) = -㏑|a| + C ........equation 1
Now use the given points; a = 1; b = 1.
-1/(1/1 + 4) = -㏑|1| + C [㏑|1| = 0]
-1/5 = C
Put the value of C in equation 1.
-1/(b/a + 4) = -㏑|a| - 1/5; is the required differential equation.

Find the kWh per day, kWh per month, and kWh per year.
Write all of them in scientific notation.
Answers
The clothes dryer uses the maximum energy at 1.018 × 10⁶ kilowatt-hour
Kilowatt-hours are primarily used to sell electrical energy to customers. A device's power consumption in kilowatts, operating time in hours, and price per kilowatt-hour are multiplied to get the cost of running it. Utility companies' charges for power may vary based on the customer's consumption patterns over time. Prices vary widely depending on the location. Prices in the US can differ by a factor of three between states.
A composite energy unit called a kilowatt-hour is defined as one kW sustained for (and multiplied by) one hour. It is equivalent to 3600 kilojoules, or 3.6 MJ, when expressed in the joule (symbol J), the SI's base unit of energy.
So from the given conditions the television uses the least amount of energy per day at 300 kilowatt-hour.
The amount of energy per year:
Television = 300 × 365 = 1.095 × 10⁵ kilowatt-hour
Dryer = 2790 × 365 = 1.018 × 10⁶ kilowatt-hour
Refrigerator = 225 × 365 = 8.213 × 10⁴ kilowatt-hour
Hence the maximum energy is used by the Dryer.

Answers
She should take the offer from the second family as she will make $5 more.
How to calculate the value?First family offers her $40 plus $5 per hour. Therefore, the amount that she can make for 5 hours will be:
= $40 + 5($5)
= $40 + $25

The value obtained from the given function f(z) = 10z²-9z+3 are-
a = 10h.b = 71h.What defined as the quotient function?A quotient function is a function that consists of two functions isolated by a division sign.The domain of the quotient between two functions, f(x) and g(x), is A ∩ B ("A intersected with B" implies the set among all points that Both A and B have in common), excluding where g(x) = 0.In mathematics, a quotient is the result of dividing one number by another.For the given function;
f(z) = 10z²-9z+3.
The quotient is given as;
Quotient = f(4+h)-f(4)
Put the values (4 + h) and 4 at the place of z in the function.
f(4+h)-f(4) = 10(4 + h)² - 9(4 + h) + 3 -[10(4)² - 9(4) + 3)]
f(4+h)-f(4) = 10h² + 160 -9h + 80h + 3 - 160 + 36 - 3
Cancel the values;
f(4+h)-f(4) = 10h² + 80h - 9h
f(4+h)-f(4) = 10h² + 71h.
Thus, comparing the obtained equation by give form of (ah + b)

Jane travels 3 times as fast as Jill. Traveling in opposite directions, they are 256 miles apart after 8 hours. Find their rates of travel.
Answers
Jane is traveling at 26.66 mph
Jill is traveling at 5.33 mph .
let the speed of jane and jill are
Jill = x mph
Jane = 5x mph
where mph= Miles per hour
To solve for speed or rate use the formula for speed, s = d/t which means speed equals distance divided by time.
we also write as -
Distance = rate x time
8x + 8(5x) = 256
8x + 40 x = 256
48x = 256
x = 256/48
x = 5.33 mph
jill is traveling at 5.33 miles per hour. We can find jane speed by put the value of x

2/3 of a number plus 1/6 of the same number is equal to 25. What is the number?
Answers
The number is 30.
Step-by-step explanation:
n=number.
2/3n+1/6n=25
Make a common denominator for 2/3 and 1/6 and then combine like terms.
4/6n+1/6n=25
5/6n=25
divide 5/6 on both sides to isolate n.
n=25/(5/6)
oreja.
n=25/1/5/6
nu(25×6)/(5×1)
n=150/5
n=30
OR
multiply the reciprocal instead of dividing.
n=25×(6/5)
n=150/5
n=30
