The difference in elevations between a scuba diver at -8 meters and a shark at -29 meters is calculated as: -8 - (-29) = 21 meters.

The subject in question involves finding the difference in elevations. In this context, the scuba diver is swimming at an elevation of -8 meters, and the shark is at -29 meters. To find the difference, we subtract the lower number (-8) from the higher number (-29).

However, due to the negative signs, the difference will be calculated as follows: -8 - (-29) = -8 + 29 = 21 meters. Therefore, the difference in elevations between the shark and the scuba diver is 21 meters.

Answer: There are 82.5% after school students who are enrolled in his classes.

Step-by-step explanation:

Let the total number of students be 100

Percentage of students who need help in computer science = 30%

So, number of students who need help in computer science = 30

Percentage of students who need help in maths = 70%

So, number of students who need assistance in maths  = 70

Of the students who need help,

40% are enrolled in Mr. Ellis's class during the school day,

So, it means 60% are enrolled in his class after the school day.

Number of students who are enrolled in his class after the school day = 60

Number of students who need help in Maths is given by

[tex]\frac{70}{100}\times 60=42[/tex]

Of the students that need help in maths, percent of students are enrolled in his class during the day = 25%

So, number of students who need help in maths and enrolled in his class after school hours

[tex]\frac{75}{100}\times 42=31.5[/tex]

Number of students who need help in computer science and enrolled in his class after school hours

[tex]\frac{30}{100}\times 60=18[/tex]

Therefore, there are [tex]31.5+18=49.5[/tex] students who joined his class after school hours,

Percentage of the after students who are enrolled in Mr. Ellis's classes is given by

[tex]\frac{49.5}{60}\times 100=82.5\%[/tex]

Hence, there are 82.5% after school students who are enrolled in his classes.

29.5% of the after-school students are enrolled in Mr. Ellis's classes.

1. Calculate the percentage of students who need help in computer science and are enrolled in his class:

  - 30% of the students need help in computer science.

  - 40% of those students are enrolled in his class during the school day.

[tex]\[ \text{Percentage of students needing help in computer science and enrolled in his class} = 30\% \times 40\% = 0.3 \times 0.4 = 0.12 = 12\% \][/tex]

2. Calculate the percentage of students who need help in math and are enrolled in his class:

  - 70% of the students need help in math.

  - 25% of those students are enrolled in his class during the school day.

[tex]\[ \text{Percentage of students needing help in math and enrolled in his class} = 70\% \times 25\% = 0.7 \times 0.25 = 0.175 = 17.5\% \][/tex]

3. Combine the two percentages to find the total percentage of after-school students enrolled in his classes:

  - 12% of the total students are those who need help in computer science and are in his class.

  - 17.5% of the total students are those who need help in math and are in his class.

Thus, the total percentage of after-school students enrolled in Mr. Ellis's classes is:

[tex]\[12\% + 17.5\% = 29.5\%\][/tex]

Answer:

1st blank is 0,14 dollars/1yuan, and 2nd blank is 1kg/2.2lb

Step-by-step explanation:

The tomatoes at the Chinese market would cost approximately $0.99 per pound, following the currency conversion rate from yuan to dollars and the weights conversion rate from kilograms to pounds.

To find the cost in dollars per pound from yuan per kilogram, we should use both the conversion rate from yuan to dollars and the conversion rate from kilograms to pounds. In this case, we are given that 1 yuan is worth 0.14 dollars and that 1 kilogram is approximately 2.20462 pounds. Therefore, the cost in yuans per pound would be 15.65 yuan/kg divided by 2.20462 lbs/kg, which equals approximately 7.09 yuan/pound. After converting it to dollars, it'd be approximately 7.09 yuan/pound times 0.14 dollars/yuan which gives us approximately $0.99 per pound.

Answer:

Step-by-step explanation:

2.) −$180/year

The average rate of change between Year 4 and Year 9 is -$180 per year.

A linear equation can be used to represent a non linear line. A linear equation is of the form:

y = mx + b

where y, x are variables, m is the slope of the line and b is the y intercept.

Let y represent the value of car after x years.

From the graph, at year 4, y = 2300, hence it is (4, 2300). At year 9, y = 1400, hence it is (9, 1400). Therefore:

[tex]Average\ rate\ of\ change=\frac{1400-2300}{9-4}= - 180[/tex]

Hence the average rate of change between Year 4 and Year 9 is -$180 per year.

Answer:

She would have to do 219 haircuts in a month for the costs to be the same, which would be $428.

Step-by-step explanation:

To find this we take the costs of the first place.

$438

Next we can look at the costs of the second place using x as the number of haircuts she'd do.

2x

Now we can set the two equal to each other to find the number of cuts.

438 = 2x

219 = x

Carrie would pay $438 and perform 219 haircuts each month.

To find out how much Carrie would pay and how many haircuts that would be, we need to set up an equation.

Let's assume the number of haircuts per month is x.

For self-employment at The Belmont Salon, Carrie would pay a fixed monthly rent of $438, so her total cost would be $438.

For the franchise option, Carrie would pay $2 for every haircut. So the total cost would be 2x.

Setting up the equation: 438 = 2x

To solve for x, we divide both sides of the equation by 2:

x = 438 / 2 = 219

Therefore, Carrie would pay $438 and perform 219 haircuts each month.

Solving the system using elimination reveals that the two equations are dependent, resulting in infinitely many solutions since they represent the same line. There is no unique solution for x and y.

To solve the system of equations 2x + 3y = 12 and -4x - 6y = -24 using the elimination method, we aim to eliminate one variable by combining the equations. First, notice that the second equation is exactly -2 times the first equation. If we multiply the first equation by 2, we would have identical left-hand sides but with opposite signs, which would cancel out when added together.

Multiplying the first equation by 2 gives 4x + 6y = 24. Now, add this new equation to the second equation:

Adding them results in 0 = 0, which indicates that the two equations are dependent, and the system has infinitely many solutions. This is because each equation is a multiple of the other, and they both represent the same line. Therefore, we cannot isolate x or y to find a unique solution. The system is consistent and dependent.

Answer:

[tex]f(x) = 3 \cdot 0.2^x[/tex]

Step-by-step explanation:

[tex]f(x) = 3 \cdot 0.2^x[/tex]

Domain of f: "What values of x can we plug into this equation?" This makes sense for all real numbers so the domain is [tex]\mathbb{R}[/tex]

Range of f: "What values of f(x) can we get out of the function?" From the graph we see we can get any real number greater than 0 out of the function by choosing a suitable x-value in the domain. The range is therefore [tex](0, \infty)[/tex].

Continuity: Since the graph is one, unbroken curve (i.e. a curve that can be drawn in one movement without taking your pen off the paper). We see that "roughly speaking" the function is continuous.

Increasing or decreasing behaviour: For all x in the domain, as x increases, f(x) decreases. This means the function exhibits decreasing behaviour.

Symmetry: It is clear to see the graph of f(x) has no symmetry.

Boundedness: Looking at the graph we see it is unbounded above as when we choose negative values, the graph of f(x) explodes upwards exponentially. Choose a value of x, plug it in, next choose (x-1), plug this in and we observe [tex]f(x-1) > f(x)[/tex] for all x in the domain.

The function is however bounded below by 0: no value of x in the domain exists which satisfies [tex]f(x) < 0[/tex].

Extrema: As far as I can tell, there are no turning points on the curve. (Is this what you mean by extrema?)

Asymptotes: Contrary to the curve's appearance, there are no vertical asymtotes for this curve. The negative-x portion of the curve is just growing so quickly it appears to look like an asymptote. There is a value of f(x) for all x<0. There is however a horizontal asymtote: [tex]y=0[/tex].

End behaviour: As [tex]x \rightarrow \infty, f(x) \rightarrow 0[/tex]. As [tex]x \rightarrow -\infty, f(x) \rightarrow +\infty[/tex]

The function f(x) = 3*0.2^x is a decaying exponential function, with a domain of all real numbers and a range of (0, ∞). It is continuous, decreasing and has a horizontal asymptote at y=0.

The function f(x) = 3*0.2^x is an exponential function with a base of 0.2. Here we're multiplying the function by a coefficient of 3.

Domain: The domain of an exponential function is always all real numbers. So, the domain is (-∞, ∞).

Range: Since this is a decaying exponential function, the output will always be between 0 (which will never actually be reached) and positive infinity. So, the range is (0, ∞).

Continuity: An exponential function is always continuous, meaning there are no holes or jumps in the graph.

Increasing or Decreasing Behavior: Since the base of the exponential (0.2) is less than 1, this function is always decreasing.

Symmetry: Exponential functions are not symmetric.

Boundedness: This function is bounded below by 0.

Extrema: There are no maximum or minimum points in this function. However, it is worth noting that the function gets closer and closer to y=0 as x goes to infinity, but never reaches it. This is sometimes considered a minimum.

Asymptotes: An asymptote is a line that the graph approaches but never reaches. For this function, the x-axis, or y = 0, is the horizontal asymptote.

End behavior: As x approaches positive infinity, y approaches 0; as x approaches negative infinity, y approaches positive infinity.

When adding two fractions, you must add them with the same denominator. This means finding the lowest common multiple of  10 and 5, which is 50. Simply multiply each fraction by the denominator of the opposite fraction:

[tex]\frac{4}{5} * 10 = \frac{40}{50}[/tex]

[tex]\frac{9}{10} * 5 = \frac{45}{50}[/tex]

Add the two fractions together:

[tex]\frac{40}{50} + \frac{45}{50} = \frac{85}{50}  = 1 \frac{35}{50} = 1 \frac{7}{10}[/tex]

7 + 1 + 1 + 7/10 = 9 7/10

4)

Again, make the denominator the same number by multiplying the fraction by the denominator of the other fraction:

[tex]\frac{3}{4} * 3 = \frac{9}{12}[/tex]

[tex]\frac{1}{3} * 4 = \frac{4}{12}[/tex]

9/12 + 4/12 = 13/12 = 1 1/12

10 + 15 + 1 + 1/12 = 26 1/12

5)

Again, multiply the fraction by the denominator of the opposite fraction:

[tex]\frac{1}{2} * 3 = \frac{3}{6}[/tex]

[tex]\frac{1}{3} * 2 = \frac{2}{6}[/tex]

3/6 + 2/6 = 5/5

7 + 6 + 4 + 5/6 = 17 5/6

Answer:

2x+ 2.1 = 7.5

x=2.7

Step-by-step explanation:

The perimeter of an isosceles triangle with sides x and y is

2x+y = P

I put y as the single side since the question said y is the shortest side.  It should say shorter sides if the two sides with the same length are smaller than the third.

We know y =2.1 and P = 7.5

Substituting these values in, we get

2x+ 2.1 = 7.5

Subtract 2.1 from each side

2x+2.1 -2.1 = 7.5 -2.1

2x= 5.4

Divide each side by 2

2x/2 = 5.4/2

x = 2.7 m
