Answer:

x = Total distance from your home to school = 1,500 meters

Step-by-step explanation:

Let

x = Total distance from your home to school

When you walked 20% of the way to school, you still have 1200 meters more to walk

Walked distance = 20% of x

= 20/100 * x

= 0.2 * x

= 0.2x

Total distance - walked distance = 1200 meters

x - 0.2x = 1200

0.8x = 1200

x = 1200 / 0.8

x = 1,500 meters

x = Total distance from your home to school = 1,500 meters

The number of beef sandwich is 48 and vegetarian sandwich is 32.

A word problem is a few sentences describing a 'real-life' scenario where a problem needs to be solved by way of a mathematical calculation.

Given that, total number of sandwiches = 160, ratio of turkey sandwiches to roast beef sandwiches = 5:3. Number of turkey sandwiches = 80

Let the number of turkey sandwich and that of roasted beef sandwich be 5x and 3x respectively,

5x = 80

x = 16

Therefore, number of roasted beef sandwiches = 16 × 3 = 48

Total number of turkey sandwich and beef sandwich = 48 + 80 = 128

The number of vegetarian sandwich = 160 - 128 = 32

Hence, the number of beef sandwich is 48 and vegetarian sandwich is 32.

In the rectangular coordinate system, every point is represented by an ordered pair. The first number in the ordered pair is the x-coordinate of the point, and the second number is the y-coordinate of the point.

Answer:

3rd box = 6

6th box = -22

y=x-12

output = input-12

Step-by-step explanation:

The input value correspond to output value = -6 is +6

The output value correspond to  input value = -10 is -22

A function rule is the relationship between the dependent and independent variables in the form of an equation.

As per the given data if we follow the pattern we get a relation between Output and Input as:

Output= Input-12

or, input= Output + 12

So, we have to find the input when output= -6

Input = -6+12

         =+6

Now, to find the output when input is -10

output= -10-12

         =-22

The length of the arc of the particle circle is equal to  23.55 units

The circumference (or) perimeter of a circle = 2πr units. The area of a circle = πr2 square units. Where r is the radius of the circle. The circumference of the circle or the perimeter of the circle is the measurement of the boundary of the circle. Whereas the area of the circle defines the region occupied by the circle.

Given here the radius of the circle as 5 units thus the length of the arc which makes an angle of π-π/2=3π/2 is angle subtended at the centre times the radius of the circle

Arc length = 5×3π/2

                  = 15π/2

                  = 15×3.14 /2

                  = 23.55 units

Hence The length of the arc of the particle circle is equal to  23.55 units

The exact value of the cotangent of theta in simplest radical form is -21/20.

What is the simplest radical form?

The simplest radical form is the expression of a radical without any factors inside the radical that can be further simplified.

To find the exact value of cotangent of theta, we need to find the values of cosine and sine of theta first.

Given that the terminal side of the angle passes through the point (21,-20), we can use the Pythagorean theorem to find the hypotenuse of the right triangle formed by the angle and the x and y-axes:

[tex]h = \sqrt{(21^2 + (-20)^2)} = \sqrt{(841 + 400)} = \sqrt{(1241)}[/tex]

Then, we can find the values of cosine and sine of theta using the x and y-coordinates of the point:

cos(theta) = adjacent/hypotenuse = 21/sqrt(1241)

sin(theta) = opposite/hypotenuse = -20/sqrt(1241)

Now we can find the value of cotangent of theta:

cot(theta) = cos(theta) / sin(theta) = (21/sqrt(1241)) / (-20/sqrt(1241))

= -21/20

Therefore, the exact value of the cotangent of theta in simplest radical form is -21/20.

4) K' = (-8,-3)    L' = (-8,-8)    M' = (-6,-8)

5) N' = (2,1)    O' = (1,6)    P' = (-2,3)

6) Q' = (0,3)    R' = (-1,-2)    S' = (3,1)

Step-by-step explanation:

All you have to do is exactly what the directions tell you to do. First, plot the original image of the triangle (The letters without the apostrophe (') behind it), and then recreate it on the opposite side of whatever axis it tells you to. The x-axis is the horizontal line, and the y-axis is the vertical line.

When you're doing this, think of it as a mirror. The mirror is whatever line it tells you to reflect the image across. The final product will be the exact same image, but reversed to the opposite of the axis chosen.

Answer: 3x + 5 = 57.50

Step-by-step explanation:

Assume that the price of one video game is x. Jamie bought 3 video games so the expression will be:

= 3x

His sister talked him into buying two $1.50 candy bars and a $2.00 drink. The total of this is:

= 1.50 + 1.50 + 2.00

= $5.00

The total amount spent on both the video game and the snacks is $57.50. Equation will therefore be:

3x + 5 = 57.50

Answer:

13cm

Step-by-step explanation:

the formula for finding the hypotenuse is:

[tex]c=\sqrt{a^{2} +b^{2} }[/tex]

C is always the longest side of the triangle. In your question, it would be the side without any measurement.

It doesn't matter which side is A and which side is B, so, suppose that A is 12 and B is 5.

Now just solve for C

C=[tex]\sqrt{12^{2} + 5^{2} }[/tex]

C=[tex]\sqrt{144+25}[/tex]

C=13

Therefore, the missing side is 13 cm
