Sara drank approximately 16.25 teaspoons of sugar in her 20-oz. bottle of soda.

This calculation is determining the amount of sugar that was consumed by Sara in her 20-oz. bottle of soda. The amount of sugar is given as 65 grams, and we are converting this quantity from grams to teaspoons.

One teaspoon of sugar is equivalent to 4 grams of sugar, so we divide the number of grams by 4 to find the number of teaspoons. The calculation is 65 grams divided by 4 grams/teaspoon, which gives us 16.25 teaspoons.

There are approximately 4 grams of sugar in a teaspoon, so 65 grams of sugar is equal to:

65 grams / 4 grams/teaspoon = 16.25 teaspoons

The value of a 45 degree angle in an isosceles right angled triangle is: 1

In an isosceles right angled triangle, where AB = BC = x, the sides AB and BC form the hypotenuse, and the remaining side AC forms one of the legs.

For the 45 degree angle (let's call it angle A), the sine function can be used to find the ratio of the opposite side to the hypotenuse:

Since the triangle is isosceles, AC = AB = x, therefore:

So the sine of a 45 degree angle in an isosceles right angled triangle is 1.

The value of z if the area to the right of z is 0.9803 is -2.06.

The area to the right of a standard normal random variable (z) can be calculated using the cumulative probability of the normal distribution. This can be done by using the formula P(z≤x) = Φ(x), where Φ is the cumulative probability of the normal distribution.

Since the area to the right of z is 0.9803, this implies that P(z≤x) = 0.9803.

Using the formula, this can be rearranged to solve for x. The rearranged equation is Φ(x) = 0.9803, which can then be solved using a standard normal table.

From the standard normal table, the value of x is found to be 2.06. This means that the value of z for the given area to the right of z is -2.06.

Therefore, the value of z if the area to the right of z is 0.9803 is -2.06.

The intersection of two functions f and g occurring midway between x = a and x = b can be calculated using the following formula: (f(x) - g(x)) = 0.

Let f and g be two functions with the domain (a,b). For f and g to intersect midway between x = a and x = b, the x-coordinate of the intersection point must be (a+b)/2. Therefore, the equation to solve is f(x) = g(x) = (a+b)/2. To solve this equation, we must first find the value of f((a+b)/2) and g((a+b)/2). Then, equate these values to each other, and solve for the variable. For example, if f(x) = x2+2x+4 and g(x) = x+7, the equation to solve is (a+b)/2 + 7 = (a+b)2/4 + 2(a+b)/2 + 4. Simplifying this equation, we get a2 - 2b2 + 2ab + 7a - 7b + 11 = 0. This equation can then be solved using the quadratic formula to find the value of a and b.

Step-by-step explanation:

x2 at origin (0,0) looks like a U porabola

in the above equation you can shift the graph up and down based on the +b.  So if the equation was, for example

F(g) = [tex]x^{2}[/tex] - 3 + 4

you would move the U shape with the origin at (0,0) up 4 and to the right 3.

The additive and multiplicative inverse of v{x} are -1 and 1 respectively.

An function in mathematics defines a relationship between one variable (the independent variable, x)  and another variable (the dependent variable, y). Example -

y = f{x} = ax + b

Given is a constant function -

v{x} = 1

We can write the additive inverse of v{x} as -

a⁻¹ (v{x}) = - v{x} = - 1

a⁻¹ (v{x}) = - 1                           ..... { 1 }

and

We can write the multiplicative inverse of v{x} as -

m⁻¹ (v{x}) = 1/v{x} = 1/1 = 1

m⁻¹ (v{x}) = 1                                ...... { 2 }

Time is the ongoing progression of existence and things that happen in what seems to be an irrevocable order from the past, present, and forward into the future.

The minute is a measure of time that is typically equal to 60 seconds, or 1/60 of an hour. Because to leap seconds, a minute occasionally has 61 seconds in the UTC time zone. The minute is acceptable for use with SI units even though it is not a SI unit. Minutes are represented by the SI unit min.

Depending on the speed of the Earth's rotation, an hour is a measure of time that is traditionally calculated as 1/24 of a day and scientifically estimated to last between 3,599 and 3,601 seconds. There are 24 hours in a day and 60 minutes in an hour.

The second is the International System of Units' unit of time, previously defined as 1/86400 of a day. This element came from the split of a day into 24 hours, 60 minutes, and then 60 seconds each.

Ur getting paid for both per month. So you would add the together.

Then they had to be greater then or equal to 100.

The correct answer to the inequality representing how much you want to earn from tutoring Math and English is '15x + 10y ≥ 100', where 'x' and 'y' represent the hours you spend tutoring Math and English, respectively, multiplied by their respective rates. You aim to earn at least $100, so the total should be equal to or exceed $100.

The question is about inequalities that represent the money you want to earn from tutoring in Math and English. 'x' represents tutoring hours in Math and 'y' represents tutoring hours in English.

We multiply these by their respective rates ($15 for Math and $10 for English) and sum them up. As you want to earn at least $100, this sum should be equal to or greater than $100.

Therefore, the correct inequality that represents this scenario is 15x + 10y ≥ 100 since you're adding, not subtracting, the possible earnings from each subject and that total needs to be greater than or equal to your desired weekly wage of $100.

So, the correct answer is C: 15x + 10y ≥ 100.

The mistake is in the second step, and the correct option is the second one (counting from the top).

The solution of the system is (2, 1).

Here someone wants to solve the system of equations below:

2x + y = 5

3x - 2y = 4

On the first step, they isolate y on the first equation to get:

y = -2x + 5

Then they substitute that on the same equation, they get:

2x + (-2x + 5) = 5

5 = 5

That is trivial, we are replacing one equation into itself.

The substitution method needs to replace that on the other equation, so there is the mistake, then the correct option is the second.

The actual solution is given by:

3x - 2*(-2x + 5) = 4

3x + 4x - 10 = 4

7x = 4 + 10

Produce per pound costs less than meat per pound because the slope of the graph for meat is greater to that of the graph for produce.

The slope of the graph tells you the unit rate in dollars per pound.

The graph of a linear function is a straight line. The following is the form of a linear function.

a + bx = y = f(x).

One independent variable and one dependent variable make up a linear function. x and y are the independent and dependent variables, respectively.

Given:

The graph's x-axis displays weight in pounds and the y-axis the cost in dollars.

The slope of a line is constant and indicates the unit rate of change.

The graph's slope, then, shows the unit rate in dollars per pound.

Also, the slope is higher on the steeper line (closer to the y-axis).

Considering the graph,

The graph of the line shows that the price of meat per pound is higher than the price of vegetables per pound.

Therefore, the line for meat is larger than the graph for produce, the price of meat per pound is higher than the price of produce per pound.

Answer:

The function C(x) that gives the total cost in a day as a function is C(x) = 0.03x + 1000

The inverse function is C^-1(x) = 100/3x - 100000/3

From the question, we have the following parameters that can be used in our computation:

Rate = $3 for every 100 reams

Initial cost = $1000

So, we have

C(x) = 3/100 * x + 1000

Evaluate

C(x) = 0.03x + 1000

To do this, we make x the subject

So, we have

0.03x = C(x) - 1000

This gives

3/100 x = C(x) - 1000

So, we have

x = 100/3 C(x) - 100000/3
