Using simple mathematical operations, David's overall loss is -5.8.
What do we mean by mathematical operations?Calculating a value while using operands as well as a math operator is known as a mathematical "operation."The supplied operands or integers must comply with a specified set of standards pertaining to the symbol of the math operator.A rule that outlines the appropriate procedures to follow when examining a mathematical equation is known as the order of operations.You can recall the PEMDAS actions parenthesis, exponents, multiplication, dividing (from Left to Right), adding, and subtracting in this order (from left to right).So, the overall gain/loss of David is:
Gain: 3.5 pounds, 1.4 poundsLoss: 8.6 pounds, 2.1 poundsNow, calculate loss/gain as follows:
3.5 + 1.4 - 8.6 - 2.14.9 - 10.7- 5.8Therefore, using simple mathematical operations, David's overall loss is -5.8.

Kyle buys $50,000 of company XYZ's shares, at a share price of
$100. A year later, XYZ's share price is $110, and Kyle sells all his
shares. How many dollars did Kyle's investment gain?
The share Kyle sells worth $55000 and Kyle's gain amount is $5000
Given,
The share bought by Kyle of company XYZ = $50,000
The share price = $100
The share price after an year = $110
We have to find the gain amount by Kyle when Kyle sells all his shares.
Here,
We can apply Unitary method;
100 ⇒ 110
50000 ⇒ x
Compute;
100x = 110 x 50000
x = (110 x 50000) / 100
x = 110 x 500
x = $55000
Now,
Kyle gains,
55000 - 50000 = $5000
That is,
The share Kyle sells worth $55000 and Kyle's gain amount is $5000

What expression is equivalent to -6(t+9)
-6t -54 is the expression equivalent to-6(t+9)
How determine equivalent expressions?Equivalent expressions are expressions that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we substitute the same value(s) for the variable(s)
Given: -6(t+9)
First, clear the parenthesis by using -6 to multiply t and 9:
-6(t+9) = (-6 x t) + (-6 x 9)
= -6t + (-54)
= -6t -54
Therefore, the -6t -54 is equivalent to -6(t+9)

The measure of the largest angle in a triangle is 110° larger than the sum of the measures of the other two angles. The measure of the smallest angle is three-
quarters the measure of the middle angle. Find the measure of each angle.
Measure of largest. smallest and middle angle of a triangle under given conditions is 145°, 15° and 20° respectively.
What is angle sum property of a triangle?
Angle sum property of triangle states that the sum of interior angles of a triangle is 180°.
According to the given question:
Let the measure of middle angle = x
The measure of the smallest angle is three-quarters the measure of the middle angle.
∴ Smallest angle = (3/4)x
The measure of the largest angle in a triangle is 110° larger than the sum of the measures of the other two angles.
∴ Largest angle = 110° + x + (3/4)x
Now, by Angle sum property of a triangle
x + (3/4)x + 110° + x + (3/4)x = 180°
On solving for the value of x we get
2x + (3/2)x = 70°
7x = 140°
x = 20°
Therefore,
measure of middle angle x = 20°
measure of smallest angle (3/4)x = 15°
measure of the largest angle 110° + x + (3/4)x = 145°

When an object is thrown upward, its height (S), in meters, is given (approximately) by the quadratic equation
S = -5t² + vt + h, where v is the upward initial velocity in meters/second, t is the time of flight in seconds, and h is the
height above level ground from which the object is thrown. Johnny is standing on a platform 16 meters high and
throws a ball straight up as high as he can at a velocity of 16 meters/second. At what time t will the ball hit the
ground?
The ball will strike the ground
seconds after it is thrown.
Check the picture below.
[tex]~~~~~~\textit{initial velocity in meters} \\\\ S = -5t^2+v_ot+h_o \quad \begin{cases} v_o=\textit{initial velocity}&16\\ \qquad \textit{of the object}\\ h_o=\textit{initial height}&16\\ \qquad \textit{of the object}\\ h=\textit{object's height}&\\ \qquad \textit{at "t" seconds} \end{cases} \\\\\\ 0=-5t^2+16t+16\implies 5t^2-16t-16=0 \\\\\\ (5t+4)(t-4)=0\implies t= \begin{cases} -\frac{4}{5}\\\\ 4 ~~ \textit{\LARGE \checkmark} \end{cases}[/tex]
the equation for meters is usually as you see in the picture but for this exercise it got rounded from -4.9 to -5, which is fine.
let's notice that "t" has two values, however the seconds cannot be a negative value, so we dismiss that one.
The ball will strike the ground 4 seconds after it is thrown When an object is thrown upward, its height , in meters, is given by the quadratic equation S = -5t² + vt + h
To find the time at which the ball will hit the ground, we need to determine when the height (S) of the ball becomes zero. At that moment, the ball will be at ground level.
The height (S) of the ball is given by the quadratic equation:
S = -5t² + vt + h
where:
S = height of the ball in meters
t = time of flight in seconds
v = initial velocity in meters/second (upward velocity, so it's positive)
h = height above level ground from which the object is thrown
Given that the initial velocity (v) is 16 meters/second, and the height above the ground (h) is 16 meters, we can substitute these values into the equation:
S = -5t² + 16t + 16
Now, to find the time (t) at which the ball hits the ground, we need to solve for t when S = 0:
0 = -5t² + 16t + 16
This is a quadratic equation in standard form (ax² + bx + c = 0), and we can solve it by factoring or using the quadratic formula. In this case, let's use the quadratic formula:
The quadratic formula is given by:
t = (-b ± √(b² - 4ac)) / 2a
In our case, a = -5, b = 16, and c = 16. Plugging these values into the quadratic formula:
t = (-(16) ± √(16² - 4*(-5)16)) / 2(-5)
t = (-16 ± √(256 + 320)) / -10
t = (-16 ± √576) / -10
Now, find the two possible solutions for t:
t₁ = (-16 + √576) / -10
t₁ = (-16 + 24) / -10
t₁ = 8 / -10
t₁ = -0.8 seconds
t₂ = (-16 - √576) / -10
t₂ = (-16 - 24) / -10
t₂ = -40 / -10
t₂ = 4 seconds
We have two solutions for t: t = -0.8 seconds and t = 4 seconds. However, we can disregard the negative value for time, as time cannot be negative in this context.
So, the ball will strike the ground 4 seconds after it is thrown.

1. The cost of bell peppers varies directly with the weight of bell peppers, as shown in the table. Write a direct variation equation to represent this relationship. Then identify the constant of variation and interpret its meaning.
The constant of variation is 1.75 for every unit increase in x (weight), and the cost(y) value increases by $ 1.75.
What is the equation?
The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
The difference between two consecutive entries is constant, as we can see = 1.75
⇒ 7 - 5.25 = 1.75
⇒ 8.75-7 = 1.75
⇒ Slope(m) = 1.75
The slope represents the variable's rate of change.
y - 3 = m(x - 5.25)
y - 5.25 = 1.75(x-3)
y = 1.76x
Thus, the constant of variation is 1.75
This indicates that for every unit increase in x (weight), the cost(y) value increases by $ 1.75.

The cost per mile incurred by Ernest Dorsey for driving the sports coupe for last year was $0.41.
How is the cost per mile derived?The cost per mile is the quotient of the division operation involving the total cost incurred and the driving mileage for the year.
To derive the total cost, add up the value of the car consumed (cost - current value), the annual variable, and fixed costs.
Cost of a used sports coupe last year = $8,000
The current value of the car = $6,000
Used value for the year = $2,000.00 ($8,000 - $2,000)
Yearly variable costs:Gasoline $1,589.56
Oil changes $245.98

The interval where the product will be at least break even equals to 18 units.
What is a break even point?In accounting, the break-even point refers to the production level at which total revenues equal total expenses.
Given data
Cost is given as C = 45x + 450
Revenue is given as: R = 70x
In this case, the point of breakeven will be:
Cost = Revenue
45x + 450 = 70x
We will collect like terms:
70x - 45x = 450
25x = 450
We will divide both side by 25:
