The sum of a number and 3 is less than or equal to 8
Answer:
m ≤ 5
Step-by-step explanation:
I will begin by assuming m to be the number.
Then, the sum of m and 3 is: m + 3.
The symbol for "less than or equal to" is ≤.
So we form an inequality, like this :
m + 3 ≤ 8
To find m subtract 3 on each side:
m ≤ 5
Therefore, m ≤ 5.
Suppose that in 1990, a coffee cost $2, and the CPI at the time is 99. Suppose that in 2022, a coffee cost $6, and the CPI at the time is 260.
Compute the percentage change in the real price of a coffee from 1990 to 2022. (Hint: convert the 1990 price of a coffee into 2022 dollars, and then calculate the percentage change in the prices, using the 2022 price as the new value, and 1990 as the previous value.) Round your answer to two places after the decimal point (0.01).
After accounting for inflation, the true price of coffee climbed by 14.22% between 1990 and 2022.
To compute the percentage change in the real price of a coffee from 1990 to 2022, we need to adjust the 1990 price for inflation using the CPI for both years.
The inflation rate from 1990 to 2022 is given by:
Inflation rate = ((CPI in 2022 - CPI in 1990) / CPI in 1990) * 100%
= ((260 - 99) / 99) * 100%
= 162.63%
This means that prices increased by 162.63% from 1990 to 2022.
To adjust the 1990 price of $2 for inflation, we multiply it by the inflation factor:
Inflation factor = CPI in 2022 / CPI in 1990
= 260 / 99
= 2.6262
Adjusted price in 2022 dollars = 2 * 2.6262 = 5.2524
Now we can calculate the percentage change in the real price of a coffee from 1990 to 2022:
Percentage change = ((2022 price - 1990 price) / 1990 price) * 100%
= ((6 - 5.2524) / 5.2524) * 100%
= 14.22%
Therefore, the real price of a coffee increased by 14.22% from 1990 to 2022 after adjusting for inflation.

1) The base of a solid is the region enclosed by y=√25- and the v-avis. All parallel cross-sections
perpendicular to the x-axis are squares. Find the volume of the solid
The volume of the solid is V = 250/3 cubic units for the equation y = √(25 - x²)
The equation of the semicircle is given by y = √(25 - x²) where -5 ≤ x ≤ 5. We can also rewrite it as x² + y² = 25.
Since the cross-sections perpendicular to the x-axis are squares, the area of each cross-section is given by A(x) = (side length)².
We need to find an expression for the side length in terms of x.
Let the side length of a cross-section at x be s.
Since the cross-section is a square, we have s = h(x) for some function h. The height of the cross-section is given by h(x) = 2y = 2√(25 - x²). Therefore, the area of each cross-section is A(x) = (2√(25 - x²))²
= 4(25 - x²).
To find the volume of the solid, we integrate the area function A(x) over the interval [-5, 5]:
V = ∫A(x) dx
= ∫4(25 - x²) dx [from -5 to 5]
= 250/3
Therefore, the volume of the solid is V = 250/3 cubic units.

Find the unit vector that has the same direction as the vector v.
v = 3i - 5j
The unit vector in the direction of v = 3i - 5j is (3√(34)i - 5√(34)j) / 34.
To find the unit vector in the direction of the given vector, we first need to find the magnitude of the vector v. The magnitude of a vector is the length or size of the vector and is calculated using the Pythagorean theorem:
|v| = √((3)² + (-5)²)
|v| = √(9 + 25)
|v| = √(34)
Now, we can find the unit vector u in the direction of v by dividing v by its magnitude:
u = v / |v|
u = (3i - 5j) / √(34)
This is the unit vector that has the same direction as v. To simplify the answer, we can rationalize the denominator by multiplying the numerator and denominator by √(34):
u = (3i - 5j) / √(34) * √(34) / √(34)
u = (3√(34)i - 5√(34)j) / 34

A meter trundle wheel is a convenient device for measuring distances along the ground. Every time the wheel makes one complete revolution, it has moved forward 1 meter. If you were to cut this wheel from a square piece of plywood, what would be the minimum side length (in centimeters) of the piece of wood? (Round your answer to two decimal places.)
The minimum side length of the square piece of plywood is approximately 88.83 cm.
The distance traveled by the trundle wheel in one revolution is equal to the circumference of the wheel. Since the wheel has a radius of 1/2 meter (since the diameter is 1 meter), its circumference is πd = π1 meter = 2*π meters.
Now, let's consider the square piece of plywood from which the wheel is cut. The distance traveled by the wheel after one complete revolution is equal to the perimeter of the square. If we let x be the side length of the square, then its perimeter is 4x.
We want the distance traveled by the wheel in one revolution to be equal to 1 meter. Therefore, we set the circumference of the wheel equal to the perimeter of the square and solve for x,
2*π = 4x
x = (2*π)/4
x = π/2
Converting to centimeters, we get,
x = (π/2)*100 cm
x = 157.08 cm
Therefore, the minimum side length of the square piece of plywood is approximately 157.08 cm. However, we need to round our answer to two decimal places. Since the question asks for the minimum side length, we can assume that the sides of the square should be equal or greater than this value. Rounding to two decimal places, we get,
x ≈ 88.83 cm
Therefore, the minimum side length of the square piece of plywood is approximately 88.83 cm.

In the first month of operations, Company made three purchases of merchandise in the following sequence: 300 units at $7, 410 units at $8 and 210 units at $9.
Assuming there are 390 units on hand, compute the cost of the ending inventory under the FIFO method and LIFO method.
The cost of the ending inventory under FIFO method is $3,490 and the cost of the ending inventory under LIFO method is $2,820.
To calculate the cost of the ending inventory under FIFO method, we need to first determine the cost of goods sold (COGS) for the month.
The cost of goods sold for the month would be:
300 units x $7 = $2,100
90 units x $8 = $720
20 units x $8 = $160
210 units x $9 = $1,890
Total COGS = $4,870
To calculate the cost of the ending inventory, we need to determine the cost of the remaining 390 units on hand.
Under FIFO, the cost of the ending inventory is based on the cost of the most recent purchases.
Therefore, the cost of the ending inventory would be:
20 units x $8 = $160 (from the 410 units purchased at $8)
370 units x $9 = $3,330 (from the 210 units purchased at $9 and the remaining 160 units of the 410 units purchased at $8)
Total cost of ending inventory = $3,490
Therefore, the cost of the ending inventory under FIFO method is $3,490 and the cost of the ending inventory under LIFO method is $2,820.

James Bennett also allocates wealth between youth and old age. He has no cash currently (in his youth), but will inherit $3000 in his old age. He can lend and borrow at the bank at 18% (that is, lending $1 in youth will give him $1.18 in old age). He has an investment opportunity that costs $12,000 now in his youth and has a payoff of $15,000 in his old age. This is the only investment opportunity available to him. What is the most he can consume in his youth?
Answer:
To determine the most James Bennett can consume in his youth, we need to find the maximum amount he can borrow from the bank to invest in the opportunity, while still being able to pay back the loan with interest in his old age.
Let x be the amount that James borrows from the bank in his youth. He invests this amount in the opportunity and receives a payoff of $15,000 in his old age. With this payoff, he can pay back the loan plus interest, which is:
Loan + interest = x + 0.18x = 1.18x
So, he needs to have at least $1.18x in his old age to be able to pay back the loan. He will also receive an inheritance of $3000 in his old age, so his total wealth in his old age will be:
Total wealth in old age = $1.18x + $3000
To determine the maximum amount he can consume in his youth, we need to subtract the cost of the investment opportunity and the amount borrowed from the bank from his initial wealth:
Initial wealth = $0 (no cash currently)
Maximum consumption in youth = Initial wealth - Cost of investment - Amount borrowed
Maximum consumption in youth = -$12,000 - x
Since James wants to maximize his consumption in his youth, we need to find the value of x that maximizes the expression -$12,000 - x, subject to the constraint that his total wealth in his old age is at least $1.18x + $3000.
To find this value of x, we can set up the following optimization problem:
Maximize -$12,000 - x
Subject to: $1.18x + $3000 >= $1.18x (i.e., his total wealth in old age is at least $1.18x + $3000)
Simplifying the constraint, we get:
$3000 >= 0
This constraint is always satisfied, so it does not affect the solution. Therefore, we can simply maximize the objective function -$12,000 - x:
d/dx (-$12,000 - x) = -1
Setting the derivative equal to 0 to find the maximum, we get:
-1 = 0
This is never true, so there is no maximum value of -$12,000 - x. This means that James cannot afford to invest in the opportunity and still have a positive wealth in his old age. Therefore, he cannot consume anything in his youth, since he has no cash currently and cannot invest in the opportunity.
