Answer:

61.2 cm²

Step-by-step explanation:

The area (A) of a trapezoid is calculated using the formula

A = [tex]\frac{1}{2}[/tex] h ([tex]b_{1}[/tex] + [tex]b_{2}[/tex] )

Substitute in given values

A = [tex]\frac{1}{2}[/tex] × 4 × (13.8 + 16.8 ) = 2 × 30.6 = 61.2 cm²

The answer is 61.2cm² .

[tex]((13.8 + 16.8) \times 4) \div 2[/tex]

This equation helps you get the answer.

The actual length of a lap cannot be determined without the scale of the map. The 25 cm measurement seems to be from the map, so without knowing the real-world equivalent of the map's measurements, we can't find the actual distance.

The length of a lap around the reservoir cannot be directly determined from the information given. The measurement provided (25 cm) appears to be a distance measured on a map or plan of the area, and not in real life. In order to convert that measurement into a real-world distance, we need the scale of the map. A map's scale is typically represented as a ratio that indicates the relationship between a certain distance on the map and the real-world distance it represents.

For example, if the map's scale was 1 cm : 1 km, then a measurement of 25 cm on the map would represent a real-world distance of 25 km. However, without the scale, we cannot accurately determine the actual length of a lap around the reservoir. This concept is extremely important in geography and cartography as well as in mathematical problems dealing with maps and scales.

Answer:

1. The other root is [tex]-2[/tex]

2. c=-106

Step-by-step explanation:

The given equation is [tex]10x^2-33x+c=0[/tex].

If [tex]5.3[/tex] is a solution to the given quadratic equation, then [tex]x=5.3[/tex] must satisfy this equation.

[tex]10(5.3)^2-33(5.3)+c=0[/tex]

[tex]280.9-174.9+c=0[/tex]

[tex]106+c=0[/tex]

[tex]c=0-106=-106[/tex]

We now substitute [tex]c=-106[/tex] into the given equation to obtain;

[tex]10x^2-33x-106=0[/tex].

Comparing to the general equation;

[tex]ax^2+bx+c=0[/tex], we have a=10, b=-33 and c=-106.

Recall the quadratic formula;

[tex]x=\frac{-b\pm \sqrt{b^2-4ac} }{2a}[/tex]

We now use the quadratic formula to obtain;

[tex]x=\frac{--33\pm \sqrt{(-33)^2-4(10)(-106)} }{2(10)}[/tex]

This implies that;

[tex]x=\frac{33\pm \sqrt{5329} }{20}[/tex]

[tex]x=\frac{33\pm73}{20}[/tex]

[tex]x=\frac{33-73}{20}[/tex] or [tex]x=\frac{33+73}{20}[/tex]

[tex]x=\frac{-40}{20}[/tex] or [tex]x=\frac{106}{20}[/tex]

[tex]x=-2[/tex] or [tex]x=5.3[/tex]

Hence the other root is [tex]-2[/tex]

Answer:

x=5

Step-by-step explanation:

-6+5=-1

start at -6 then go right units until u get -1 you got right 5 units

The value of x in the given equation is:

                              x=5

We are given a algebraic expression in terms of the variable x by:

             [tex]-6+x=-1[/tex]

Now, we are asked to find the value of x from the equation.

i.e. we have to solve for x.

i.e. by some appropriate algebraic operation we need to solve for x.

so we will add 6 on both the sides of the equation to get:

[tex]-6+x+6=-1+6\\\\i.e.\\\\-6+6+x=5\\\\i.e.\\\\0+x=5\\\\i.e.\\\\x=5[/tex]

           Hence, the value of x is: 5

Answer:

[tex]y=-6(x-1)^{2}-7[/tex]

Step-by-step explanation:

we have

[tex]6x^{2} -12x+y+13=0[/tex]

Convert to vertex form

Group terms that contain the same variable, and move the constant to the opposite side of the equation

[tex]y+13=-6x^{2} +12x[/tex]

Factor the leading coefficient

[tex]y+13=-6(x^{2} -2x)[/tex]

Complete the square. Remember to balance the equation by adding the same constants to each side.

[tex]y+13-6=-6(x^{2} -2x+1)[/tex]

[tex]y+7=-6(x^{2} -2x+1)[/tex]

Rewrite as perfect squares

[tex]y+7=-6(x-1)^{2}[/tex]

[tex]y=-6(x-1)^{2}-7[/tex] -----> equation of the parabola in vertex form

The vertex is (1,-7) is a maximum, the parabola open downward

To convert 6x^2 - 12x + y + 13 = 0 to vertex form, follow the steps to complete the square and rewrite the equation as (x - 1)^2 = -y/6 - 7/6.

The equation 6x^2-12x+y+13=0 is in the general form of a quadratic equation. To convert it into the vertex form, we need to complete the square.

First, let's group the x terms together: 6x^2 - 12x = -(y + 13).

Next, let's complete the square: 6(x^2 - 2x) = -(y + 13).

Now, we can add (2/2)^2 = 1 to both sides to complete the square: 6(x^2 - 2x + 1) = -(y + 13) + 6.

Simplifying further, we get 6(x - 1)^2 = -y - 7.

Finally, we can write the equation in vertex form by dividing both sides by 6: (x - 1)^2 = -y/6 - 7/6.

Answer:

B. There is an association because the value 0.15 is not similar to the value 0.55

Step-by-step explanation:

Based on the above picture, for the nutritionist to determine whether there is an association between where food is prepared and the number of calories the food contains, there must be an association between two categorical variables.

The conditions that satisfy whether there exists an association between conditional relative frequencies are:

1. When there is a bigger difference in the conditional relative frequencies, the stronger the association between the variables.

2. When the conditional relative frequencies are nearly equal for all categories, there may be no association between the variables.

For the given conditional relative frequency, we can see that there exists a significant difference between the columns of the table in the picture because 0.15 is significantly different from 0.55 and 0.85 is significantly different from 0.45

We can conclude that there is an association because the value 0.15 is not similar to the value 0.55

Answer:There is an association because the value 0.15 is not similar to the value 0.55.

Step-by-step explanation:

We can make and use the equation: A = 160( 1.03 )^y: A = amount, 160 = amount put in, 1 + .03 = 1.03 = interest, and y as the number of years, as the money is compounded every year. (This is the compound interest equation, but I put in the numbers)

A) 160 * 1.03 = $164.80, 160 * 1.03² = $169.744 ≈ $169.74

B) 160 * 1.03⁵ = 185.48385 ≈ $185.48

The expression is the same as saying (((((160 * 1.03)1.03)1.03)1.03)1.03). This is like multiplying 160 * 1.03, which gives the amount for the first year. Then, that amount is multiplied by 1.03, which is the amount for the second year. This isi repeated until 5 years.

C) 160(1.03)³⁰

Claire will have $164.80 after 1 year and $169.74 after 2 years in her savings account due to the 3% interest rate. After 5 years, she will have $185.86. The expression for the amount after 30 years is $160 × (1.03)³⁰.

When Claire deposited $160 into her savings account at a 3% interest rate per year, she initiated a process of compound interest. This means each year, the amount of money in her account will increase by 3% of the amount from the previous year. The way to find out how much money she will have after a certain number of years is to multiply the initial amount by 1.03 raised to the power of the number of years.

Interest After 1 Year

After 1 year: $160 × 1.03 = $164.80

Interest After 2 Years

After 2 years: $160 × (1.03)² = $169.74

Interest After 5 Years

After 5 years: $160 × (1.03)⁵ = $185.86. This is calculated using the formula for compound interest: $160 × 1.03 raised to the fifth power.

Interest After 30 Years

To write an expression for the amount of money she will have in 30 years: $160 × (1.03)³⁰. This follows the general formula for compound interest, which is the initial amount times one plus the interest rate raised to the number of years.

Final answer:

Using the given information, the total travel time by airplane and bus is calculated as 4.47616 hours, which includes flying time and additional travel time by bus.

Explanation:

To calculate the total travel time by airplane including the additional travel time by bus, we must first find out the time taken by the airplane to cover the distance between the two airports. This can be done by dividing the distance by the airplane's average speed. Afterward, we add the bus travel time to get the total travel time.

The time taken by the airplane to cover 1,450 miles at an average speed of 350 mph is calculated by dividing distance by speed: 1,450 miles ÷ 350 mph = 4.142857 hours. Note that we do not round this number to maintain accuracy.

Next, we convert the bus travel time of 20 minutes into hours: 20 minutes ÷ 60 minutes per hour = 0.3333 hours.

Now, we add both the airplane and bus travel times together: 4.142857 hours + 0.3333 hours = 4.47616 hours total travel time.

The graph for the following system of inequalities is attached below.

Step-by-step explanation:

The given system of inequalities is

[tex]x+y>3[/tex]                    .... (1)

[tex]x+y<-4[/tex]                  .... (2)

From inequality (1) and (2) it is clear that (x+y) is greater than 3 adn 3 is not less than -4. So, the given system of inequality has no feasible reason or solution.

The related equation of first inequality is

[tex]x+y=3[/tex]

Put x=0 to find the y-intercept.

[tex]0+y=3\Rightarrow y=3[/tex]

The y-intercept is 3.

Put y=0 to find the x-intercept.

[tex]x+0=3\Rightarrow x=3[/tex]

The x-intercept is 3.

The related equation of second inequality is

[tex]x+y=-4[/tex]

Put x=0 to find the y-intercept.

[tex]0+y=-4\Rightarrow y=-4[/tex]

The y-intercept is -4.

Put y=0 to find the x-intercept.

[tex]x+0=-4\Rightarrow x=-4[/tex]

The x-intercept is -4.

The related lines are dotted line because the sign of inequalities are > and <.

Check each inequality be (0,0).

[tex]0+0>3[/tex]

[tex]0>3[/tex]

This statement is false. So the shaded region of first inequality is opposite sides of the origin.

[tex]0+0<-4[/tex]  

[tex]0<-4[/tex]  

This statement is false. So the shaded region of first inequality is opposite sides of the origin.

Answer:

19.32

Step-by-step explanation:

One way to find the missing number is to get the value of the left side of the equation first.

8.4(1.5 + 2.3) = 31.92

Now we need to take that value and subtract it to the value on the right side of the equation.

31.92 - 12.6 = 19.32

So we have:

8.4(1.5 + 2.3) = 12.6 + 19.32

31.92 = 31.92

Answer:

The required number is 19.32

Step-by-step explanation:

Consider the provided expression.

Let the missing number is x.

[tex]8.4(1.5 + 2.3) = 12.6 +x[/tex]

Add the numbers as shown.

[tex]8.4(3.8) = 12.6 +x[/tex]

Open the parentheses.

[tex]31.92= 12.6 +x[/tex]

Subtract 12.6 from both the sides.

[tex]31.92-12.6= 12.6-12.6 +x[/tex]

[tex]x=19.32[/tex]

Hence, the required number is 19.32

Mark Brainliest if this helps!

Final answer:

An exact number is one that is known with complete precision, such as the number of books on a shelf. An approximate number, or inexact number, includes uncertainty and comes with an error range, often due to measuring limitations such as estimating a length with a ruler. The level of rounding applies to approximate values determines their reliability, and significant figures are influenced by inexact numbers.

Explanation:

The difference between an exact number and an approximate number lies in their level of precision and the source of the number. Exact numbers are count numbers that are known with complete precision. An example of an exact number is the number of students in a classroom, which might be exactly 25. On the other hand, inexact numbers, also known as measured numbers, come with an error range due to the limitations of measuring instruments or methods. For instance, when using a ruler, you might measure a length as approximately 12.7 cm, but the true length might be slightly less or more.

It's important to note that the more rounding that is applied to a number, the less reliable it becomes. Approximations are common in various fields, including physics, where scientists and engineers make educated guesses, or 'guesstimates', based on available data and formulae with limited accuracy. These approximations are essential for problem-solving and can help in making quantitative decisions and realistic predictions.

Conversion factors in measurements are considered to be exact numbers because they are defined as such by the measurement systems. In calculations involving both exact and inexact numbers, the precision of the inexact numbers dictates the number of significant figures in the result.
