Answer:

Step-by-step explanation:

The perimeter of a square with side a = 7.2 cm is 28.8 cm. Yes there exists a direct proportional relationship between Side length and Perimeter of square

Given that side of square "a" = 7.2 cm

We have to find the perimeter of square

The perimeter of square is given as:

Perimeter of square = 4a

Where "a" represents the length of side of square

Substituting the given value a = 7.2 cm in above formula, we get perimeter of square

Perimeter of square = 4(7.2) = 28.8 cm

Are the perimeter of the square and the length of its side directly proportional quantities?

[tex]\begin{array}{l}{\text { perimeter of square }=4 a=4 \times \text { length of side }} \\\\ {\frac{\text { perimeter of square }}{\text { length of side }}=4}\end{array}[/tex]

The Perimeter is equal to a constant times the Side length, or the Perimeter divided by the Side length is equal to four. So this is definitely a proportional relationship between Side length and Perimeter.

Two values are said to be in direct proportion when an increase in one results in an increase in the other.

So when length of sides increases, perimeter also increases

Hence perimeter and length of side of square are directly propotional quantities

Answer:

The numbers are 23 and 24

Step-by-step explanation:

Let

x ----> the first positive consecutive integer

x+1 ----> the second positive consecutive integer

we know that

The product of the two consecutive positive integers is 552

so

The algebraic expression that represent this situation is

[tex]x(x+1)=552[/tex]

Convert to expanded form

[tex]x^2+x-552=0[/tex]

Solve the quadratic equation by graphing

The roots of the equation are

[tex]x_1=-24[/tex] ----> the number cannot be negative

[tex]x_2=23[/tex]

see the attached figure

therefore

[tex]x=23\\x+1=24[/tex]

The numbers are 23 and 24

To find two consecutive positive integers whose product is 552, set up the equation x(x + 1) = 552, expand and solve the quadratic equation.

To find two consecutive positive integers whose product is 552, we can set up the equation x(x + 1) = 552, where x represents the smaller integer.

Expanding the equation, we get x^2 + x - 552 = 0. This is a quadratic equation, and we can solve it by factoring or using the quadratic formula.

Factoring the quadratic equation, we find that (x - 23)(x + 24) = 0. So the two consecutive positive integers are 23 and 24.

The area of the large sail is 144 square feet.

To find the area of the large sail, we can use the formula for the area of a triangle which is Area = 1/2 * base * height.

In this case, the base of the sail is 12 feet and the height (or the length of the sail) is 24 feet. Plugging these values into the formula, we get:

Area = 1/2 * 12 feet * 24 feet = 144 square feet

Therefore, the area of the large sail is 144 square feet.

The store charges $8 for one red dot CD and $10 for one green dot CD.

Step-by-step explanation:

Given,

Red dot CDs = r

Green dot CDs = g

According to given statement;

4r+2g=52   Eqn 1

3r+g=34    Eqn 2

Multiplying Eqn 2 by 2;

[tex]2(3r+g=34)\\6r+2g=68\ \ \ Eqn\ 3\\[/tex]

Subtracting Eqn 1 from Eqn 3

[tex](6r+2g)-(4r+2g)=68-52\\6r+2g-4r-2g=16\\2r=16[/tex]

Dividing both sides by 2;

[tex]\frac{2r}{2}=\frac{16}{2}\\r=8[/tex]

Putting r=8 in Eqn 2

[tex]3(8)+g=34\\24+g=34\\g=34-24\\g=10[/tex]

The store charges $8 for one red dot CD and $10 for one green dot CD.

By setting up and solving a system of linear equations based on the information that Collette bought 2 green-dot and 4 red-dot CDs for $52, and Jakara bought 3 red-dot CDs and 1 green-dot CD for $34, we determined that the price of each green-dot CD is $10 and each red-dot CD is $8.

Collette and Jakara went shopping at a local music store which had CDs marked with a red dot, r, at one price and CDs marked with a green dot, g, at another price. Collette bought 2 green-dot CDs and 4 red-dot CDs for $52, and Jakara bought 3 red-dot CDs and 1 green-dot CD for $34. To determine the prices for each type of CD, we set up a system of equations based on the information provided:

2g + 4r = 52 (Equation 1: Collette's purchase)

1g + 3r = 34 (Equation 2: Jakara's purchase)

We can solve this system of equations using either the substitution or the elimination method. In this answer, we will use the elimination method.

Multiply Equation 2 by 2 to align the coefficients of g: 2g + 6r = 68

Subtract Equation 1 from the new version of Equation 2 to eliminate g: (2g + 6r) - (2g + 4r) = 68 - 52

This simplifies to 2r = 16, so divide by 2 to find r: r = 8

Use the value of r to solve for g in Equation 1: 2g + 4(8) = 52

This simplifies to 2g + 32 = 52, so subtract 32 from each side: 2g = 20

Finally, divide by 2 to find g: g = 10

Therefore, the price of a green-dot CD is $10 and the price of a red-dot CD is $8.

About 158 students in the district participate in the school music program.

Step-by-step explanation:

394(2/5)=788/5=157.6

Answer:

C

Step-by-step explanation:

Using the distributive property of multiplication, we can say that 4x+4y-10 >= x+6y-4. Since we want to solve for y, we'll remove the x from one side (in this case, the left). Subtracting 4x from both sides, we get that 4y-10 >= -3x+6y-4. Separating the y, we can similarly subtract 6y from both sides to get rid of the y on the right and add 10 to both sides to get rid of the 10 on the left, resulting in -2y >= -3x+6. As we want to separate y, we must multiply our inequality by a negative number (-1/2, to be exact, as 1/(-2) = -1/2). However, when we multiply by a negative number, we must flip the sign. Thus, if we multiply both sides by -1/2, our result is y<= 1.5x+3, or C

In a kite, generally there is only 1 line of symmetry which runs from the vertex angle where the two sides of unequal length meet to the vertex angle directly opposite. Therefore, in the case of kite ABCD, the correct answer is option A) 1 line of symmetry.

In the field of mathematics, a kite is a quadrilateral shape with two pairs of adjacent sides that are the same length. When thinking about the lines of symmetry, you should keep in mind that symmetry means that one half of the figure is a mirror image of the other half. For a kite, the number of lines of symmetry is generally 1. The line of symmetry in a kite runs from the vertex angle where the two sides of unequal length meet, to the vertex angle directly opposite.

This means, in the case of kite ABCD, there is 1 line of symmetry.

So, the correct option is A) 1 line of symmetry.

To calculate the total number of homes in Lora's community, the number of flyers distributed (630) is divided by the percentage of homes that received flyers (35%), resulting in a total of 1800 homes.

To find the total number of homes in Lora's community, we need to set up a proportion where the number of flyers delivered represents 35% of all homes. Since Lora distributed flyers to 630, that is 35% of the total homes. Using the percentage formula:

Total Homes = Distributed Flyers / Percentage of Homes

So, in this case, it would be:

Total Homes = 630 / 0.35

Dividing 630 homes by 0.35 (35% as a decimal) gives us:

Total Homes = 1800

Therefore, there are 1800 homes in Lora's community.

Step-by-step explanation:

Answer:

The correct answer is B. Exponential form.

Step-by-step explanation:

The exponential form was developed to express repeated multiplications and to make it easier to write long numbers. The exponential notation has two parts. The base, as the name says, is the number below. The other part of the notation is a small number written on the superscript to the right of the base, called an exponent. We will use an example to learn about the exponential form or notation.

2³

In this example the base is 2. This means that 2 is a factor, and that it will be multiplied by itself a certain number of times. The precise number of times is given by the exponent, the number in the superscript. In this case, the exponent is 3, which means that base 2 will be used as a factor 3 times. So  2³ means 2 • 2 • 2 and the result is 8.

James has 55 dimes in the bag

Step-by-step explanation:

The given is:

We need to find how many dimes James has

Assume that the number of nickels is x and the number of

dimes is y in the bag

∵ There are x nickels in the bag

∵ There are y dimes in the bag

∵ There are 77 coins in the bag

∴ x + y = 77 ⇒ (1)

∵ 1 nickel = 5 cents

∴ The value of nickles in the bag = 5x cents

∵ 1 dime = 10 cents

∴ The value of dimes in the bag = 10y cents

∵ The total value of coins is $6.60

∵ 1 dollar = 100 cents

∴ $6.60 = 6.60 × 100 = 660 cents

∴ 5x + 10y = 660 ⇒ (2)

Now we have a system of equations to solve it

Multiply equation (1) by -10 to eliminate y

∵ -10x - 10y = -770 ⇒ (3)

- Add equations (2) and (3)

∴ -5x = -110

- Divide both sides by -5

∴ x = 22

Substitute the value of x in equation (2) to find y

∵ 22 + y = 77

- Subtract 22 from both sides

∴ y = 55

∴ The number of dimes is 55

James has 55 dimes in the bag

Answer:

27 miles.

Step-by-step explanation:

The distance between two points ([tex]x_{1},y_{1}[/tex]) and ([tex]x_{2},y_{2}[/tex]) on the coordinate plane are given by the formula

[tex]\sqrt{(x_{2} - x_{1})^{2} + (y_{2} - y_{1})^{2}  }[/tex]

Therefore, the distance between points (12,6) and (12,15) is [tex]\sqrt{(12 - 12)^{2} + (15 - 6)^{2}} = 9[/tex] units

Again, the distance between the points (12,15) and (4,0) is [tex]\sqrt{(4 - 12)^{2} + (0 - 15)^{2}} = 17[/tex] units

And the dictance between the points (4,0) and (12,6) is [tex]\sqrt{(12 - 4)^{2} + (6 - 0)^{2}} = 10[/tex] units

Therefore, the total distance is (9 + 17 + 10) = 36 units.

Answer:

x = 85

Step-by-step explanation:

There are two triangles. For the purpose of communication, I label them as right triangle and acute triangle.

All triangles' interior angles must add to 180°.

Since we already have two of the three angles in the acute triangle, we can find the third angle, which I label as "y":

180° = 25° + 60° + y

180° = 85° + y

180° - 85° = 85° - 85° + y

y = 95°

Supplementary angles are angles that add to 180°. This is true of any straight lines.

In this question, the angles x and y are supplementary because they make up a straight line.

x + y = 180°

x + 95° = 180°

x = 85°

Without all these steps, we can also figure out that x = 85 by adding 60° and 25° because the sum of a triangles' two interior angles are equivalent to the supplementary of the third angle.

The number of adults = 41

The number of children = 97

Step-by-step explanation:

Let x be the number of adults and

y be the number of children

then according to the given conditions

[tex]x+y = 138\ \ \ Eqn\ 1\\11x+4y = 839\ \ \ Eqn\ 2[/tex]

From equation 1:

x = 138-y

Putting in equation 2

[tex]11(138-y)+4y = 839\\1518-11y+4y = 839\\1518 -7y = 839\\-7y = 839-1518\\-7y = -679\\[/tex]

Dividing both sides by -7

[tex]\frac{-7y}{-7} = \frac{-679}{-7}\\y = 97[/tex]

Putting y = 97 in equation 1

[tex]x+ 97 = 138\\x = 138-97\\x = 41[/tex]

Hence,

The number of adults = 41

The number of children = 97

Cross-multiplying

[tex]q(t+3) = 2-4t\\qt+3q = 2-4t[/tex]

Adding 4t on both sides

[tex]qt+3q+4t = 2-4t+4t\\qt+3q+4t = 2[/tex]

Subtracting 3q from both sides

[tex]qt+3q+4t-3q = 2-3q\\qt+4t = 2-3q[/tex]

Taking t common on left hand side

[tex]t(q+4)=2-3q[/tex]

Dividing both sides by q+4

[tex]\frac{t(q+4)}{q+4}=\frac{2-3q}{q+4}\\t = \frac{2-3q}{q+4}[/tex]

The formula after making t subject of the formula is:

The exponential function with a horizontal asymptote y = -7 that passes through the points (0, -6) and (1, 6) is:

y = [tex]e^{(ln(13)x)} - 7[/tex].

To find an exponential function with a horizontal asymptote y = -7 that passes through the points (0, -6) and (1, 6), we can use the general form of an exponential function:

[tex]y = A * e^{(kx)} + C[/tex]

where A is the initial value, k is the growth/decay rate, e is the base of the natural logarithm (approximately 2.71828), x is the independent variable, and C is the y-coordinate of the horizontal asymptote.

Step 1: Determine the value of C (the y-coordinate of the horizontal asymptote):

Since the asymptote is y = -7, we set C = -7.

Step 2: Use the given points to find A and k:

For point (0, -6):

-6 = A * e⁰ - 7

-6 + 7 = A

A = 1

For point (1, 6):

6 = 1 * [tex]e^{(k*1)[/tex] - 7

13 = [tex]e^{k[/tex]

Step 3: Solve for k:

Take the natural logarithm of both sides: ln(13) = k

Step 4: Write the exponential function:

The exponential function with a horizontal asymptote y = -7 that passes through the points (0, -6) and (1, 6) is:

y = [tex]e^{(ln(13)x)} - 7[/tex].

This function will have a horizontal asymptote at y = -7 and pass through the given points (0, -6) and (1, 6).
