Answer: 169.2cm

Step-by-step explanation:

From the question, we are informed that three equal-sized cardboard boxes are stacked on top of each other and that each box is 56.4 cm in height.

To get the combined height of the 3 stacked boxes, we multiply 56.4cm by 3. This will be:

= 56.4cm × 3

= 169.2cm

Answer:

The answer is below

Step-by-step explanation:

Let the money charged to wrap a small gift be $x and the money charged to wrap a large gift be $y. The cost of wrapping 14 small gifts and 15 large gifts is $205, It can be represented by the equation:

14x + 15y = 205                 (1)

Also, the cost of wrapping 47 small gifts and 45 large gifts is $640. It can be represented by the equation:

47x + 45y = 640                 (2)

Solving equation 1 and equation 2 simultaneously. Multiply equation 1 by 3 and subtract from equation 2:

5x = 25

x = 25/5 = 5

x = 5

Put x = 5, in equation 1 and solve:

14(5) + 15y = 205

15y + 70 = 205

15y = 205 - 70

15y = 135

y = 135 / 15

y = 9

This means that the money charged to wrap the small gift is $5 and to wrap the large gifts is $9

Answer:

y = [tex]\frac{21}{4}[/tex]

Step-by-step explanation:

Given

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

Multiply through by 6 to clear the fractions

y - 3 = 18 - 3y ( add 3y to both sides )

4y - 3 = 18 ( add 3 to both sides )

4y = 21 ( divide both sides by 4 )

y = [tex]\frac{21}{4}[/tex] = 5.25

Answer:

Step-by-step explanation:

Answer:

x = 5 and x = 11

Step-by-step explanation:

The segment through the center is a perpendicular bisector of the chord, thus

5x - 6 = 2x + 9 ( subtract 2x from both sides )

3x - 6 = 9 ( add 6 to both sides )

3x = 15 ( divide both sides by 3 )

x = 5

-------------------------------------------------------

Tangents to a circle from an external point are congruent, thus

4x - 1 = 3x + 10 ( subtract 3x from both sides )

x - 1 = 10 ( add 1 to both side

Answer:

x = 5 and x = 11

Step-by-step explanation:

The segment through the centre is a perpendicular bisector of the chord, thus

5x - 6 = 2x + 9 ( subtract 2x from both sides )

3x - 6 = 9 ( add 6 to both sides )

3x = 15 ( divide both sides by 3 )

x = 5

-------------------------------------------------------

Tangents to a circle from an external point are congruent, thus

4x - 1 = 3x + 10 ( subtract 3x from both sides )

x - 1 = 10 ( add 1 to both sides )

x = 11

Answer:

x= ±2 sqrt(3)

Step-by-step explanation:

4x^2+11= 59

Subtract 11 from each side

4x^2+11-11= 59-11

4x^2 = 48

Divide by 4

4/4x^2 = 48/4

x^2 = 12

Take the square root of each side

sqrt(x^2) = sqrt(12)

x = ±sqrt(4*3)

x= ±2 sqrt(3)

Subtract 11 from each side

4x^2+11-11= 59-11

4x^2 = 48

Divide by 4

4/4x^2 = 48/4

x^2 = 12

Take the square root of each side

sqrt(x^2) = sqrt(12)

x = ±sqrt(4 x 3)

Answer: x=24

Step-by-step explanation:

The four angles form a linear pair and a linear pair is basically a line which means it forms 180°.

(x-5)+(3x-1)+(2x-6)+(2x)=180

Take off parentheses

x-5+3x-1+2x-6+2x=180

Move like terms together

x+3x+2x+2x-5-1-6=180

Combine like terms

8x-12=180

Add 12 on both sides

8x-12+12=180+12

8x=192

Divide 8 on both sides

8/8 x=192/8

x=24

Answer:

x=2

Step-by-step explanation:

x=2

x+1=3

and 3 is a prime

Answer:

A counterexample is x = 3

Step-by-step explanation:

We are given that x is a prime number, and x + 1 is not a prime number. However consider the number 3. We know that 3 is a prime number, as it is present as factors of 1 and itself. However 3 + 1 = 4 - which falls into the category of a composite number, as it can divide into 2 * 2. Therefore your counterexample could be x = 3.

Step-by-step explanation:

if you were to break up each of these into segments, A, and B, would not add additionally to 95.61 degrees, minutes, and seconds. C is most definitly wrong because the inch mark, and foot" marks are wrong, and there is no degree mark. Espiecailly since its not possible to be 950 degree.

Answer:

-x + 2y + 1 > 0

Step-by-step explanation:

Let's find the equation of the dashed line first. From the graph, we can see that it has a slope of 1/2 and a y-intercept of -1/2 so using slope-intercept form, the equation of the line is y = 1/2x - 1/2. Since the line is dashed and not solid, we know that we will use either < or > instead of ≤ or ≥, and because we can see that the shaded region is above the dashed line, we know that the linear equation is y > 1/2x - 1/2. However, we want the answer to be in the form ax + by + c > 0 where a, b, and c are integers so therefore:

y > 1/2x - 1/2

= 2y > x - 1

= -x + 2y + 1 > 0

A linear inequality is an expression which make comparison between linear expressions using inequalities. The linear inequality of the graph is: [tex]-x + 2y +1 > 0[/tex]

First, we calculate the slope of the dashed line using:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

Two points on the graph will be:

[tex](x_1,y_1) = (1,0)[/tex]

[tex](x_2,y_2) = (3,1)[/tex]

The slope (m) is:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m = \frac{1-0}{3-1}[/tex]

[tex]m = \frac{1}{2}[/tex]

The equation of the line is calculated as:

[tex]y = m(x - x_1) + y_1[/tex]

So, we have;

[tex]y = \frac12(x - 1) + 0[/tex]

[tex]y = \frac12(x - 1)[/tex]

Multiply through by 2

[tex]2y= x - 1[/tex]

Now, we convert the equation to an inequality.

The line on the graph is a dashed line. This means that the inequality is either > or <. Also, the upper region of the graph that is shaded means that the inequality  is >.

So, the equation becomes

[tex]2y > x-1[/tex]

Rewrite as:

[tex]-x + 2y +1 > 0[/tex]

So, the linear inequality is: [tex]-x + 2y +1 > 0[/tex]

-8(2x +x )/-2y =(-8•3x)/-2y = [-8•3(-5)] / (-2•2) = 120/(-4) =-30

Answer:

B; C; A; B

Step-by-step explanation:

So, let's go through each of the choices.

So we know that one of the angles is 60 degrees.

I) The triangle is scalene.

This might be true. Since there are 180 degrees in a triangle, and we know 60, that leaves 120 degrees. Anything two combinations of different values that add up to 120 will make the triangle scalene. However, if the two values are the same (e.g. 60;60), they it's not scalene. Thus, this might be true.

II) The other two angles add up to 120.

This must be true. The interior angles sum of a triangle is 180. Since we already know one is 60, then the other two must add up to be 180-60 or 120.

III) The other two angles are obtuse.

This cannot be true. We know that there is only 120 degrees left in the triangle. Obtuse angles are greater than 90 degrees.

Therefore, if we subtract the minimum: 120-90, we will get at most 30 left. This is not enough for another obtuse angle. The most we can have is one obtuse angle and two acute angles.

IV) The triangle is right-angled.

This might be true. Since there are 120 degrees left, the other two degrees may be 90 and 30, given us 30-60-90. This, however, doesn't have to be it. So, this statement may be true.
