Step-by-step explanation:

First of all, a very easy way is to count all the rectangles and then count the squares that are shaded and have balloons.

You'll get 7 squares that are shaded and have balloons and 16 rectangles in total.

So the fraction will be [tex]\frac{7}{16}[/tex]

Another simple way is to just multiply [tex]\frac{7}{8}[/tex] and [tex]\frac{1}{2}[/tex]

[tex]\frac{7}{8}*\frac{1}{2}=\frac{7}{16}[/tex]

lol

Answer:

y = 18

Step-by-step explanation:

Just let x = 12

y = 6 + x

y = 6 + 12

y = 18

When x = 12, y = 18.

The graph is included to show you what y = 6 + x looks like and it also shows the point (12,18) = (x,y)

Answer:

{-8, 8}

Step-by-step explanation:

Simplify   7· |n| = 56 by dividing both sides by 7:  

|n| = 8

Because this is an absolute value equation, there are two separate solutions.  One is n = +8 and the other is n = -8.

There are two solutions.

[tex]

7\times\mid n\mid=56\Longrightarrow\mid7n\mid=56 \\

\mid7\times x_1\mid=56\Longrightarrow x_1=\frac{56}{7}=\boxed{8} \\

\mid7\times(-x_1)\mid=56\Longrightarrow-x_2=\frac{56}{7}\Longrightarrow x_2=\boxed{-8}

Answer:

B. x + y = 14 and x - y = 2

Step-by-step explanation:

Sum means addition, so the sum of the tens digit (x) and the ones digit (y) is equal to 14 (x + y = 14).

Difference means subtraction, so the difference between the tens digit (x) and the ones digit (y) is 2 (x - y = 2).

I hope this helps =)

Answer:

Option B. will be the answer.

Step-by-step explanation:

If the tens digit is x and ones digit is y, then the number formed will be xy.

Now we fill form the equations as per statements given in the question.

"The difference between tens and unit digits is 2"

x - y = 2 --------(1)

"Sum of the digits of two digit number is 14"

x + y = 14 -------(2)

Therefore, system of equations will be as the given equations 1 and 2.

Option B is the answer.

Answer:

1.68

Step-by-step explanation:

1. Move all of the terms to the left side and set the problem equal to zero.

2. Set each factor equal to zero.

For this case we have the following equation:

[tex]6 ^ {- x} + 4 = 3x-1[/tex]

We must clear the value of x, we follow the steps below:

We subtract 3x on both sides of the equation:[tex]6 ^ {- x} -3x + 4 = -1[/tex]

Add 1 to both sides of the equation:

[tex]6 ^ {- x} - 3x + 4 + 1 = -1 + 1\\6 ^ {- x} - 3x + 5 = 0[/tex]

Each side of the equation is drawn, then the solution is the x value of the intersection point.

Exact Answer : 255.6

Answer:

(-7,8)

Step-by-step explanation:

The coordinates of the points dividing the line segment in ratio m:n can be calculated as:

[tex](\frac{mx_{1}+nx_{2}}{m+n} ,\frac{my_{1}+ny_{2}}{m+n} )[/tex]

Here x1, y1 are the coordinates of first point J (-10, 12) and x2, y2 are the coordinates of second point K(8, -12).

In this case m will be 5 and n will be 1 as the ratio is 5:1

Using all these values we can find the coordinates of point L

[tex]( \frac{5(-10)+1(8)}{5+1},\frac{5(12)+1(-12)}{5+1} )\\\\ = (\frac{-42}{6} ,\frac{48}{6} )\\\\ =(-7,8)[/tex]

Thus, the coordinates of point L which divides the line segment JK in 5:1 are (-7,8)

The coordinates of point L, which divides the line segment JK in the ratio 5:1, are (5,-8).

To find the coordinates of point L that divides the line segment JK in the ratio 5:1, we use the formula for section formula in coordinate geometry. This formula provides the coordinates of a point that divides a line segment into a specific ratio. The formula is X = (m1*x2 + m2*x1) / (m1+m2), Y = (m1*y2 + m2*y1) / (m1+m2), where m1 and m2 are the ratios.

Here, J(-10,12) is x1,y1 and K(8,-12) is x2,y2. The point L is dividing JK in the ratio 5:1, so m1=5 and m2=1. Substituting these values:

X = (5*8 + 1*-10) / (5 + 1) = 30 / 6 = 5, Y = (5*-12 + 1*12) / (5 + 1) = -48 / 6 = -8.

Therefore, the coordinates of point L are (5,-8).

Final answer:

In mathematics, the right triangle definition of tan theta is the ratio of the length of the side opposite to theta (y) to the length of the side adjacent to theta (x).

Explanation:

The right triangle definition of tan theta (tan θ) involves the ratio of the lengths of two specific sides of the triangle. According to SOHCAHTOA, a mnemonic used to remember the definitions of the sine, cosine, and tangent functions, tan theta is the ratio of the opposite side (y) to the adjacent side (x) of the right triangle, where theta (θ) is one of the non-right angles. This can be written as tan(θ) = y/x.

In other words, the tangent of an angle θ in a right triangle is defined as the ratio of the length of the side opposite the angle to the length of the side adjacent to the angle.

This can be represented as:

tan(θ) = Opposite side / Adjacent side = y / x

For example, if the opposite side y is 5 units and the adjacent side x is 3 units, then tan(θ) = 5 / 3

The Pythagorean Theorem may be applied in conjunction with the definitions of trigonometric functions to solve various problems involving right triangles, but it specifically relates to the relationship between the sides of a right triangle: a² + b² = c², where 'a' and 'b' are the lengths of the legs, and 'c' is the length of the hypotenuse.

When solving problems related to right triangles, it is beneficial to remember that the sum of the angles of a triangle is always equal to two right angles (or 180 degrees).

We'll assume that the CPI is given for the END of the year.

This is a pretty poor question.  The questioner should clarify the exact dates of the given values of the CPI, and use the actual values.   44% is an alarming inflation rate, but fortunately a fictitious one here in the US.  US inflation in 2014 was around 0.7% so the number the student was asked to compute was off by more than a factor of sixty.

The equation of the line passing through points O(0,0) and P(8,-6) is y = -3/4x.

To find the equation of a line, we need to determine its slope and y-intercept. The slope can be found using the formula (y2 - y1) / (x2 - x1) where (x1, y1) and (x2, y2) are coordinates of two points on the line. In this case, we have the coordinates of points O and P: O(0,0) and P(8,-6).

The slope of the line passing through O and P is (-6 - 0) / (8 - 0) = -6 / 8 = -3 / 4.

Since the line passes through the origin (0,0), its y-intercept is 0. Therefore, the equation of the line is y = -3/4x.

Final answer:

The number of eggs Ty has left after making 4 servings of scrambled eggs, using n eggs for each serving, is represented by the algebraic expression 10 - 4n.

Explanation:

To determine the number of eggs Ty has left after making scrambled eggs, we need to use a simple algebraic expression. If Ty started with 10 eggs and used n eggs for each of the 4 servings, we can represent the number of eggs used in total as 4n.

To find the number of eggs remaining, we subtract the total number of eggs used from the initial number of eggs:

Number of eggs remaining = Initial number of eggs - Number of eggs used

Number of eggs remaining = 10 - 4n

Step-by-step explanation:

[tex]\frac{k}{3} = \frac{16}{24}[/tex]            Set up your equation

24k=48                                                      Cross multiply

k=2                                                             Divide 24 from both sides

You answer is k=2

For this case we have the following equation:

[tex]\frac {k} {3} = \frac {16} {24}[/tex]

We must find the value of the variable "k":

Simplifying the right side of the equation we have:

[tex]\frac {k} {3} = \frac {8} {12}\\\frac {k} {3} = \frac {4} {6}\\\frac {k} {3} = \frac {2} {3}[/tex]

[tex]\frac{ {y}^{2} }{49} + \frac{ {x}^{2} }{ 16 } = 1[/tex]

EXPLANATION

The given ellipse has a vertex at (0, -7), a co-vertex at (4,0), and a center at the origin.

The equation of an ellipse with vertex on the y-axis and center at the origin is given by

[tex]\frac{ {y}^{2} }{a ^{2} } + \frac{ {x}^{2} }{ {b}^{2} } = 1[/tex]

[tex]\frac{ {y}^{2} }{( - 7) ^{2} } + \frac{ {x}^{2} }{ {4}^{2} } = 1[/tex]

[tex]\frac{ {y}^{2} }{49} + \frac{ {x}^{2} }{ 16 } = 1[/tex]

The equation of the ellipse with a vertex at (0, -7), a co-vertex at (4,0), and a center at the origin is x^2/16 + y^2/49 = 1.

To find the equation of the ellipse in standard form, we need to identify the lengths of the major and minor axes. The given vertex at (0, -7) indicates that the semi-major axis length, a, is 7 because the distance from the center to a vertex measures the semi-major axis. Similarly, the co-vertex at (4, 0) represents the semi-minor axis length, b, which is 4.

Since the center is at the origin (0, 0), the standard form of the ellipse equation is given by x^2/b^2 + y^2/a^2 = 1. Plugging the values of a and b, we get x^2/4^2 + y^2/7^2 = 1. So, the equation of the ellipse is x^2/16 + y^2/49 = 1.

Answer:

p = 1/6

Step-by-step explanation:

5/6 - 1/3 n = p(5-2n)

Multiply each side by 6 so we do not have any fractions

6(5/6 - 1/3 n) = 6*p(5-2n)

5 - 2n = 6p (5-2n)

Divide each side by (5-2n) to isolate 6p

(5-2n)/(5-2n) = 6p (5-2n)/ (5-2n)

1 = 6p

Now divide by 6 to get p alone

1/6 = 6p/6

1/6 = p
