A rectangle's base is 3 in shorter than five times its height. The rectangle's area is 68 in?. Find this rectangle's dimensions.
The rectangle's height is 2 in, and the rectangle's base is 5 x 2+ 3 = 30 in, whose area is given as 68in².
What is rectangle?It has two pairs of equal-length sides that are at right angles to each other. It is the most common type of quadrilateral, and it can be found in everyday objects like windows, doors, and tabletops.
To solve this problem, we need to use the formula for the area of a rectangle (A = l x w), where A is the area, l is the length, and w is the width. We also know that the base is 3 inches shorter than 5 times the height. Therefore, we can set up the equation to solve for the height and the base of the rectangle as follows:
A = l x w
A = (h + 3) x (5h)
A = 5h² + 3h
5h² + 3h = 68
h= -2 (as height can not be in negative)
h= 2
By using the quadratic formula, we can solve for the height, h, which is equal to 2.
Therefore, the rectangle's height is 2 in, and the rectangle's base is 5 x 2+ 3 = 30 in.
This problem was solved by using the quadratic equation to solve for the height of the rectangle, which was then used to solve for the base.

He completed volunteering in 39 hours 40 minutes in 4 weeks
How to determine this
If Ken volunteers 1 hr 25 mins each day
i.e 1 hr 25 mins = 1 days
By converting 1 hr 25 mins to mins
When 60 mins = 1 hr
1 hr 25 mins = 60 + 25 = 85 mins
How many hours of volunteering is completed in 4 weeks
Let x represent the numbers of hours
i.e x = 4 weeks
By converting 4 weeks to days
When 7 days = 1 week
4 weeks = 4 * 7 days
= 28 days
So, when 85 mins = 1 day
x mins = 28 days
x = 28 days * 85 mins/1 day
x = 2380 mins
By converting it back to hour
When 60 mins = 1 hour
2380 mins = x
x = 2380/60 hour
x = 39 hours 40 mins
Therefore, the hours that can be completed in 4 weeks is 39 hours 40 minutes

what expression is equivalent to 91 plus 39?
Answer: 130
Step-by-step explanation:
The problem is asking for an expression that is equivalent to the addition of 91 and 39. An expression is a combination of numbers, variables, and mathematical operations that does not have an equal sign. In this case, the expression we are looking for should evaluate to the same value as the sum of 91 and 39, which is 130.
To obtain this expression, we simply add 91 and 39, since the sum of these two numbers is equivalent to the expression we are looking for. Adding 91 and 39, we get:
91 + 39 = 130
Therefore, the expression that is equivalent to 91 plus 39 is simply 130.

The kite is approximately 18.57 yards high above the edge of the pond.
How to solve for the height of the kiteThe Pythagorean theorem would be used to solve the prob;lem that we have here
The theorye tell us that the squatre of the hypotenuse is the same as the sum of the square of the other two sides
The formula is written as
c^2 = a^2 + b^2
In this case:
c = 37 yards (length of the string)
a = 32 yards (distance from where the kite is tied to the ground to the edge of the pond)
b = height of the kite above the edge of the pond (which we need to find)
Now, plug the values into the Pythagorean theorem:
37^2 = 32^2 + b^2
1369 = 1024 + b^2
Subtract 1024 from both sides:
b^2 = 345
Now, take the square root of both sides to solve for b:

y = - [tex]\frac{3}{4}[/tex] x - 4 → (2)
substitute y = [tex]\frac{1}{2}[/tex] x + 6 into (2)

5x + 24 = - 16 ( subtract 24 from both sides )
5x = - 40 ( divide both sides by 5 )
x = - 8
substitute x = - 8 into either of the 2 equations and evaluate for y

Break-Even Sales
BeerBev, Inc., reported the following operating information for a recent year (in millions):
Sales $6,512
Cost of goods sold $1,628
Gross profit $4,884
Marketing, general, and admin. expenses 592
Income from operations $ 4,292
Assume that BeerBev sold 37 million barrels of beer during the year, that variable costs were 75% of the cost of goods sold and 50% of marketing, general and administration expenses, and that the remaining costs are fixed. For the following year, assume that BeerBev expects pricing, variable costs per barrel, and fixed costs to remain constant, except that new distribution and general office facilities are expected to increase fixed costs by $21.09 million.
a. Compute the break-even sales (in barrels) for the current year. Round your answer to two decimal places. Enter your answers in millions.
The break even sales for the current year using the contribution per unit is 5.27.
The formula to find the break even sales is,
Break even sales = Fixed costs / Contribution per unit
Now,
Contribution per unit = Sales price per unit - Variable cost per unit.
Sales price = $6,512
Variable cost = (75% × cost of goods sold) + (50% × marketing, general and administration expenses)
= (75% × $1,628) + (50% × $592)
= $1517
Contribution margin = $6,512 - $1517 = $4995
Contribution per unit = $4995 / 37 = $135 per million
Fixed costs = (25% × cost of goods sold) + (50% × marketing, general and administration expenses)
= $703
Break even sales = 703 / 135 = 5.21
Hence the break even sales is 5.27.

4. How many combinations are possible on a 4 number computer cable lock. Each space can
be any number 0 - 9. The only exception is that all four numbers cannot be the same.
How many combinations are possible?
The possible number of combinations are 9,720.
What is combination?In mathematics, a combination is a way of selecting a subset of items from a larger set, where the order of selection does not matter. The number of combinations of size k that can be chosen from a set of n items is denoted by the symbol C(n,k) or sometimes by ⁿCk, and is given by the formula:
C(n,k) = n! / (k! ×(n - k)!)
Define number?A number is a mathematical concept used to represent quantity or value. It can be a whole number, such as 1, 2, 3, or a decimal, such as 1.5 or 3.14. Numbers are used in various mathematical operations, such as addition, subtraction, multiplication, and division. They are also used in everyday life for counting and measuring.
There are a total of 9,720 possible combinations for a 4-number computer cable lock where each space can be any number 0-9, except for the restriction that all four numbers cannot be the same. To arrive at this number, we can first calculate the total number of possible combinations without the restriction, which is 10⁴ = 10,000. Then we subtract the number of combinations where all four numbers are the same, which is simply 10 (i.e. 0000, 1111, 2222, etc.), to get 9,990. Finally, we subtract the number of combinations where all four numbers are the same and also subtract the number of combinations where three out of four numbers are the same (which is simply 10×4 = 40 since there are 10 possible values for the repeated number and 4 possible positions for it), which gives us a final count of 9,720.

Find the angle of depression from the top of a lighthouse 400 feet above water level to the water line of a ship 18,410 ft offshore? Round your answer to the nearest hundredth of a degree.
To find the angle of depression, we can use the tangent function in trigonometry. In this situation, we have a right triangle where the height (opposite side) is 400 feet, and the distance (adjacent side) is 18,410 feet.
tan(angle) = opposite / adjacent
tan(angle) = 400 / 18,410
Now, we'll use the arctangent (inverse tangent) function to find the angle:
angle = arctan(400 / 18,410)
angle ≈ 1.25 degrees

The two buses drove towards each other at constant speeds. The first left NY at 11AM and arrived in Boston at 4 PM, and the second left Boston at 12 PM and arrived in NY at 5 PM. What time did they meet?
The two buses meet at the same time they left their respective cities, so they meet at 11 AM in NY.
Since the two buses are traveling towards each other at constant speeds, we can use the formula for finding the time two objects meet when traveling at constant speeds in opposite directions:
t = (d2 - d1)/(v1 + v2)
Where t is the time they meet, d1 is the distance the first bus travels, d2 is the distance the second bus travels, v1 is the speed of the first bus, and v2 is the speed of the second bus.
In this case, d1 is the distance between NY and Boston (approx. 200 miles), d2 is the distance between Boston and NY (also approx. 200 miles), v1 is the speed of the first bus (200 miles in 5 hours, or 40 miles/hour), and v2 is the speed of the second bus (200 miles in 5 hours, or 40 miles/hour).
Plugging these values into the formula, we get:
t = (200 - 200)/(40 + 40)
t = 0/80
t = 0
Hence, the two buses meet at the same time they left their respective cities, so they meet at 11 AM in NY.

Suppose that the polynomial function f is defined as follows.
The zeros of f according to their multiplicity are:
Zero of multiplicity 1: x = -8, x = -3, x = 0, x = 9
Zero of multiplicity 2: None
Zero of multiplicity 3: None
Here,
We have,
The zeros of a polynomial function are the values of x that make the function equal to zero. The multiplicity of a zero is the number of times it appears as a factor in the polynomial.
In the given function f(x), the zeros are the values of x that make the function equal to zero.
We can find these values by setting the function equal to zero and solving for x.
f(x) = 7x(x-9)(x+8)^2(x+3) = 0
Therefore, the zeros of f(x) are x = -8, x = -3, x = 0, and x = 9.
To determine the multiplicity of each zero, we can look at the degree to which the corresponding factor appears in the polynomial.
For example, x = -8 is a zero of multiplicity 2 because it appears as a factor twice in the function, as (x+8)^2.
Similarly, x = -3, x = 0, and x = 9 are zeros of multiplicity 1 because they each appear as a factor once in the function.
There are no zeros of multiplicity 3 or higher in this function, so we can list "None" for those categories.
