Final answer:
The unit rate for meat priced at $32 for 8 pounds is $4 per pound. This method of calculation is important in retail settings, such as butcher shops, where items need to be labeled with the correct price per unit.
Explanation:
The unit rate is calculated by dividing the total price by the number of pounds of meat to determine the price per pound. For $32 and 8lbs of meat, the calculation is $32 ÷ 8lbs, which equals $4 per pound.
This price is a simplified example of how goods are priced on a per unit basis. For instance, if we were discussing the price of fish, the price per pound at an equilibrium quantity may be $3.25 per pound, which is specific to the commercial market.
Real-world Application
Grocery pricing often includes bulk pricing, discounts, or access fees, and the final cost consumers pay can be represented in various unit rates, like $xx.xx/unit in some cases. It’s important for workers in retail settings, such as at a butcher shop or grocery, to understand these concepts to label and price items accordingly.

Find the circumference and area of a circle whose radius is 12.4 cm.Give your answer to the nearest centimeter (whole #). Circumference = cm Area = cm2
Final answer:
The circumference of the circle is approximately 78 cm and the area of the circle is approximately 484 cm².
Explanation:
The circumference of a circle can be found by using the formula:
Circumference = 2πr, where r is the radius of the circle.
Given that the radius is 12.4 cm, we can substitute this value into the formula:
Circumference = 2π(12.4 cm)
Using an approximation of π as 3.14, the calculation becomes:
Circumference = 2(3.14)(12.4 cm) = 77.9 cm
Therefore, the circumference of the circle is approximately 78 cm (to the nearest whole number).
The area of a circle can be found by using the formula:
Area = πr²
Substituting the given radius into the formula:
Area = 3.14(12.4 cm)² = 483.864 cm²
Therefore, the area of the circle is approximately 484 cm² (to the nearest whole number).

A 10 foot ladder is placed 4-feet from the edge of a building. How far up the building does the ladder reach? Round your answer to the nearest tenth of a foot.
A:10.8 feet
B:9.2 feet
C:2.4 feet
D:3.7 feet
The ladder is 9.2 feet up the building
The length (L) of the ladder is given as:
[tex]L = 10ft[/tex]
The distance (d) from the edge of the building is
[tex]d = 4ft[/tex]
The distance up the ladder is the height (h) of the ladder on the wall.
This is calculated using the following Pythagoras theorem
[tex]L^2 = d^2 + h^2[/tex]
So, we have:
[tex]10^2 = 4^2 + h^2[/tex]
Evaluate the exponents
[tex]100 = 16 + h^2[/tex]
Subtract 16 from both sides
[tex]84 = h^2[/tex]
Take square roots of both sides
[tex]9.2 = h[/tex]
Rewrite as
[tex]h =9.2[/tex]
Hence, the ladder is 9.2 feet up the building

A house purchased for $226,000 has lost 4% of its value each year for the past five years. What is it worth now?
Answer:
The answer would be $184,274.23.
Step-by-step explanation:
After a 4% annual decrease in value over five years, a house that was bought for $226,000 would be worth around $183,896.7.
Explanation:The student's question pertains to a situation where a house's value depreciates, in this case, at a rate of 4% per year for five years. To find out how much the house would be worth now, we need to employ the formula for depreciations, that is P = P0 (1 - r)^n, where P is the final value, P0 the initial value, r the rate of decrease and n the number of periods the decrease has occurred over.
In this case, P0 would be the initial value of the house $226,000, r would be 4% (or 0.04 as a decimal), and n would be the number of years, which is 5. Substituting these values into the formula gives us and calculated we get P = $226,000 * (1 - 0.04)^5 = $183,896.7.
So after a 4% annual decrease in value over five years, the house that was bought for $226,000 would now be worth around $183,896.7.

The range of possible sizes for side 'x' is from 1.5 to 4.5, inclusive of both endpoints.
Explanation:The question "What is the range of possible sizes for side xxx?" refers to finding the possible values that the variable 'x' can take. From the information provided, we understand that 'x' can be any number in the inclusive range from 1.5 to 4.5, which can be denoted mathematically as 1.5 ≤ x ≤ 4.5. This means that the smallest value 'x' can be is 1.5, and the largest value is 4.5. The range of possible sizes for 'x' is therefore between 1.5 and 4.5, including both of these endpoints.

A normal distribution has a mean of 186.4 and a standard deviation of 48.9.
What range of values represents the upper 2.5% of the data?
a
X > 235.3
b
X > 333.1
c
X > 284.2
d
X > 186.4
We have been given that a normal distribution has a mean of 186.4 and a standard deviation of 48.9. We are asked to find the range of value that represents the upper 2.5% of the data.
We know that upper 2.5% of data would be 97.5% of data.
We will use z-score formula to solve our given problem.
[tex]z=\frac{x-\mu}{\sigma}[/tex], where,
z = z-score,
x = Random sample score,
[tex]\mu[/tex] = Mean,
[tex]\sigma[/tex] = Standard deviation.
Now we will use normal distribution table to find z-score corresponding to 97.5% area or 0.975.
We can see from the normal distribution table that z-score corresponding to area 0.975 is [tex]1.96[/tex].
[tex]1.96=\frac{x-186.4}{48.9}[/tex]
Let us solve for x.
[tex]1.96\cdot 48.9=\frac{x-186.4}{48.9}\cdot 48.9[/tex]
[tex]95.844=x-186.4[/tex]
[tex]95.844+186.4=x-186.4+186.4[/tex]
[tex]282.244=x[/tex]
Therefore, the range [tex]x>282.244[/tex] represents the upper 2.5% of the data.

Which is the graph of f(x) = -(x + 3)(x + 1)?
Answer:
Step-by-step explanation:
Setting f(x) = -(x + 3)(x + 1) = 0 leads to identifying two roots/solutions of this equation: x = -3 and x = -1. The axis of symmetry is a vertical line halfway between these two roots: x = -2. This x = -2 is also the x-coordinate of the vertex. Evaluating f(x) = -(x + 3)(x + 1) at x = -2 gives us the y-coordinate of the vertex: y = -(-2 + 3)(-2 + 1) = -(1)(-1) = 1.
In summary, the vertex is at (-2, 1) and the two x-intercepts are (-3, 0) and (-1, 0). The y-intercept is found by setting x = 0 and finding y:
f(0) = -(0 + 3)(0 + 1) = -3, or (0, -3)

He has between 10 and 20 batteries. He counts the batteries by putting them into piles of 4 and finds that he has 3 left over. He then counted them by putting them into piles of 3 and found that he had one left over. How many batteries does he have?
Answer:
15 batteries
Step-by-step explanation:
If he puts the batteries in piles of 4, and there is 3 left over, the number of batteries he can have is:
2 piles: 4*2 + 3 = 11
3 piles: 4*3 + 3 = 15
4 piles: 4*4 + 3 = 19
Then, when he puts in piles of 3, there is no batteries left over, so the number of batteries is a multiple of 3.
From the 3 possibilities above (11, 15 and 19), only the number 15 is a multiple of 3, so the number of batteries is 15.

Find the missing factor. 5y^2+4y-1=(5y-1)()
Answer:
(5y−1)(y+1)
Step-by-step explanation:
Answer:
(y + 1 )
Step-by-step explanation:
Given
5y² + 4y - 1
Consider the factors of the product of the y² term and the y- term which sum to give the coefficient of the y- term
product = 5 × - 1 = - 5 and sum = + 4
The factors are + 5 and - 1
Use these factors to split the y- term
5y² + 5y - y - 1 ( factor the first/second and third/fourth terms )
= 5y(y + 1) - 1(y + 1) ← factor out (y + 1) from each term
= (y + 1)(5y - 1)
The missing factor is (y + 1)
The mass of the cylinder is 50,000 g. Find the density of the cylinder to the nearest tenth
answer choices
0.7 g/mm3
81.2 g/mm3
2.7 g/mm3
0.4 g/mm3
Answer:
Density of the Cylinder = 2.7 g/mm³
Step-by-step explanation:
Density of a cylinder is calculated using the formula =
Mass of the Cylinder ÷ Volume of the Cylinder
Step 1
The First step is to find the Volume of the Cylinder.
Volume of a Cylinder = πr²h
In the attached image , we are given:
Diameter of the Cylinder = 28mm
Radius of the Cylinder = Diameter ÷ 2 = 28mm ÷ 2
Radius of the Cylinder (r) = 14mm
Height of the Cylinder (h) = 30mm
The Volume of the Cylinder = πr²h
= π × (14mm)² × 30mm
= 18472.564803 mm³
Step 2
The second step would be to find the Density of the Cylinder.
Density of the Cylinder = Mass of the Cylinder ÷ Volume of the Cylinder
Mass of the Cylinder = 50,000g
Volume of the Cylinder = 18472.564803 mm³
Density of the Cylinder = 50,000g ÷ 18472.564803 mm³
= 2.7067167193 g /mm³
Approximately the Density of the Cylinder = 2.7 g/mm³
Jason owns a food truck that sells tacos and burritos. He sells each taco for $4.75 and each burrito for $7.50. Yesterday Jason made a total of $790 in revenue from all burrito and taco sales and there were twice as many burritos sold as there were tacos sold. Write a system of equations that could be used to determine the number of tacos sold and the number of burritos sold. Define the variables that you use to write the system.
let t be the number of tacos sold
let b be the number of burritos sold
Step-by-step explanation:
b=2t
4.75t+7.50b=790
To solve the problem, set up two variables T and B for the number of tacos and burritos sold. Two equations are formed: B = 2T (since twice as many burritos as tacos were sold) and 4.75T + 7.50B = 790 (from the total revenue). Solve these to find T and B.
Explanation:To determine the number of tacos and burritos sold by Jason's food truck, we need to establish two variables: let T represent the number of tacos sold, and let B represent the number of burritos sold. Given that burritos are sold at a ratio of two to every one taco, we can express this relationship with the equation B = 2T. Next, using the given prices of tacos ($4.75) and burritos ($7.50), along with the total revenue of $790, we can write the budget constraint equation as 4.75T + 7.50B = 790. These two equations together form the system of equations that can be solved to find the number of tacos (T) and burritos (B) sold.
