The ordered pair for Y is (-4,-2)

Step-by-step explanation:

Given

X(-2,3)

Z(-6,-7)

As Y is the mid-point of XZ, it will divide Xz in two equal segments. Y is the mid-point of the segment.

Let (x_Y, y_Y) be the coordinates of the mid-point

Then

[tex](x_Y, y_Y) = (\frac{x_1+_2}{2} , \frac{y_1+y_2}{2})[/tex]

Putting the values

[tex]=(frac{-2-6}{2} , \frac{3-7}{2})\\=(\frac{-8}{2} , \frac{-4}{2})\\=(-4, -2)[/tex]

Hence,

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.

There are 2561 girls in the school.

Step-by-step explanation:

2610-49=2561

There are 1331 girls in the school.

Equation is defined as a relation that equates two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

Given are 49% of students at a school are boys. There are 2610 students at the school.

Assume that there are [x] girls are there. Then, we can write -

x = 2610 - 49% of 2610

x = 2610 - (49/100) x 2610

x = 2610 - 1279

x = 1331

Therefore, there are 1331 girls in the school.

1 gallon of liquid is equivalent to 16 cups of the liquid

1 gallon = 16 cups

Therefore

1 gallon = (10 x 16) servings

1 gallon = 160 servings

160 servings can be made using 1 gallon of milk.

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

Add the total males together: 13 + 85 = 98,

So the total male need to be 98,

the total adults is given as 200.

The total women would be 200 - 98 = 102

The table with those three totals is table D.

Answer: It's D

Step-by-step explanation:

First, look at the sum of both female and male adults. As it states in the question, they must add up to 200. Therefore, there are 98 males under 6 ft. So, graph that shows 98 females under 6ft is correct. Which is D in this case.

Answer:

The solutions of the equation are t = 4(√5 + 1) or 4(√5 - 1).

Step-by-step explanation:

We have to solve the given quadratic equation of single variable t.

The equation is 16 = 2t + 0.25t²

⇒ 0.25t² + 2t - 16 = 0

⇒ 25t² + 200t - 1600 = 0 {Multiplying both sides with 100}

⇒ 25t² + 200t + 400 - 400 - 1600 = 0

⇒ (5t + 20)² - 2000 = 0

⇒ (5t + 20)² - (20√5)² = 0

⇒ (5t + 20 + 20√5)(5t + 20 - 20√5) = 0

So, (5t + 20 + 20√5) = 0 or, (5t + 20 - 20√5) = 0

⇒ (t + 4 + 4√5) = 0 or, (t + 4 - 4√5) = 0

⇒ t = - 4(1 + √5) or, t = 4(√5 - 1) (Answer)

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

Answer:

The difference in slopes of [tex]f(x)\ and\ g(x)[/tex] is = 3

We can say slope of [tex]f(x)[/tex] is positive  and 3 more than slope of [tex]g(x)[/tex] while slope of [tex]g(x)[/tex]  is negative.

Difference of y-intercepts of [tex]f(x)\ and\ g(x)[/tex] is = -7

We can say the y-intercept of [tex]g(x)[/tex] is positive and 7 units above [tex]f(x)[/tex] while y-intercept of [tex]f(x)[/tex]  is negative.

Step-by-step explanation:

Given equation:

[tex]f(x) =2x - 2[/tex]

[tex]g(x) =5-x[/tex]

We need to find the difference of slopes and y-intercepts of the given equations.

The standard form of a slope intercept equation of line is given by:

[tex]y=mx+b[/tex]

where [tex]m[/tex] represents slope and [tex]b[/tex] represents y-intercept of line.

Writing the given equations in standard form to find slope and y-intercept.

[tex]f(x) =2x +(-2)[/tex]

Slope = 2 and y-intercept =-2

[tex]g(x) =(-1)x+5[/tex]

Slope = -1 and y-intercept =5

The difference in slopes of [tex]f(x)\ and\ g(x)[/tex] is = [tex]2-(-1)=2+1=3[/tex]

We can say slope of [tex]f(x)[/tex] is positive  and 3 more than slope of [tex]g(x)[/tex] while slope of [tex]g(x)[/tex]  is negative.

Difference of y-intercepts of [tex]f(x)\ and\ g(x)[/tex] is = [tex]-2-5=-7[/tex]

We can say the y-intercept of [tex]g(x)[/tex] is positive and 7 units above [tex]f(x)[/tex] while y-intercept of [tex]f(x)[/tex]  is negative.

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.

If each unit on the coordinate plane represents 0.75 miles, then Tony rides on the city bus by (36 × 0.75) =27 miles. (Answer)

Answer:

178 m

Step-by-step explanation:

The area of a square is the square of one of its sides, so the square root of the area is the length of one of its sides.

√31684 = 178

Since you know the area of a square is lengh times width,

you can do…

length x width= 31684

but since you know that length=width

it is just length squared=31684

so,

length= square root of 31684

at the end length of each side of a square are the the same so, if you know one then you know all of the others,

so,

length of each side in this square is=178 meters

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.

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.

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.

Since the average weight of a coconut is 2.22 kg less than a watermelon, its average weight is

[tex]4.61-2.22=2.39[/tex]Let n be the number of coconuts and watermelons. The total weight of n coconuts and n watermelons is

[tex]4.61n+2.39n = 7n[/tex]

If we want this total to be 140, we have

[tex]7n=140 \iff n=\dfrac{140}{7}=20[/tex]

So, you have 20 coconuts and 20 watermelons.

Final answer:

To find the number of coconuts, we can set up an equation using the given information. The average weight of a watermelon is 4.61 kg, and the average weight of a coconut is 2.22 kg less than a watermelon. By setting up the equation x(4.61 + 2.39) = 140 and solving for x, we find that there are 20 coconuts.

Explanation:

To solve this problem, we need to set up equations using the given information. Let's represent the number of coconuts as 'x'. The average weight of a watermelon is 4.61 kg, and the average weight of a coconut is 2.22 kg less than a watermelon, which means it is 4.61 - 2.22 = 2.39 kg. Since the number of coconuts and watermelons is equal, we can write the equation: x(4.61 + 2.39) = 140. Solving this equation, we get 7x = 140, which means x = 140/7 = 20.

Therefore, there are 20 coconuts.

Step-by-step explanation:

Given formula is:

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

To make t the subject of the formula we have to isolate t

So,

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 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
