Answer: Assuming that you mean 1in:2ft the model house would be 13 inches wide.

Step-by-step explanation: well 1 is half of 2 right? So if you want to get the numbers easier to use then just divide that 26 by 2 and then you get the scale 1in:1ft. From there it is easy, 13 feet of the real house= 13 inches in the model house

Answer:

0.29 or 29%

Step-by-step explanation:

There are 7 options per spin. Of which 3 vowels.

For 2 spins, total spins is 14.

conditions:

First spin is 1/7

Second spin is 3/7

so,

4/14 = 0.29 or 29% I think

Based on the information provided, the mean number of people in a class is 21 people.

To calculate the mean number, the general formula is the total of people in the class/ number of classes.

Then, let's find the total of people in classes by adding the number of people that are in class every day:

13+23+24+31+14 =  105 people in total

Number of classes: 5 classes or 5 days

The mean number of people in a class: Divide the total of people by the number of classes

105 / 5 = 21 people per class in average

Answer:

(2,-3) and (49/29, -108/29)

Step-by-step explanation: Assuming this is an exam and time is limited, first you gotta sketch the circle for clarity. Using the standard circle equation

(x-a)^2 + (y-b)^2 = r^2

(x-1)^2 + (y+3)^2 =1

You can always expand to verify it gives x^2 + y^2 - 2x + 6y + 9=0

Now you know (a,b) which is also the center of the circle being= (1,-3) and the radius(r) = 1

Your first assumption here even without drawing the circle is that it has to be in the fourth quadrant meaning all values of x for any point of intersection on that circle has to be +ve. Looking at your answer choices only c with is (2,-3) and (49/29, -108/29) fulfills this hence it is your answer.

Also you have to realize point (2,-3) on the straight line has same y coordinates with center of this circle.

Answer:

y int = -2

slope = 1

Step-by-step explanation:

x-y=2

-y=-x+2

y=x-2

y int = -2

slope = 1

Answer:

Slope = 1

Y-intercept = -2

Step-by-step explanation:

   First, we will put it into slope-intercept form.

x - y = 2

x = y + 2

y = x - 2

   This gives us the slope of one and the y-intercept being -2.

Answer:31800grams

Step-by-step explanation:

Answer:

Given that the area of the base is 440.4, all we would need to find out is the sum of all the areas of the triangles surrounding it.

Formula for area of a triangle:

A = BH x 1/2

Where 'B' represents the base, 'H' stands for the height, and 1/2 simply means to divide the product of those two lengths(base and height) by 2.

Plug in what we know:-

A = BH x 1/2

A = 16(20) x 1/2

A = 320 x 1/2

A = 320/2

A = 160 mm is the area of one triangle, but we want to know the area of all 5 triangles, so;

160(5)

= 800 mm is the area of all the triangles.

Now add the base area to the area of all the triangles.

440.4 + 800

= 1,240.4 mm.

Therefore the surface area of this pyramid is 1,240.4 mm.

Answer:

1240.4 mm²

Step-by-step explanation:

The surface area of a pyramid = Area of the all sides + Area of base

Each side is a triangle.

With a regular pentagonal pyramid, the area of each triangle is

A = 1/2 x base x slant height

For the 5 triangles,

A = 5 x 1/2 x base x slant height = 1/2 x 5 x slant height

Substitute values,

A = 5 x 1/2 x 16mm x 20mm = 800 mm²

Area of base = 440.4 mm²

Surface area of a pyramid = 800 + 440.4 mm² = 1240.4 mm²

Answer:

see below

Step-by-step explanation:

When a = -1   and  b = -2    U = a-b    

                                                   -1 - -2 = 1    U =1

when a = -4   and  b = 1          V = a-b =   - 4 - 1 =-5    V = -5

m∠C = 52°

Solve:

m∠A + m∠B + m∠C = 180°

36° + 92° + m∠C = 180°

m∠C = 180°  - 92° - 36°

m∠C = 52°

Answer:

  not a right triangle

Step-by-step explanation:

The side lengths of a right triangle will satisfy the relation given by the Pythagorean theorem:

  c² = a² +b²

  23² = 14² +19²

  529 = 196 +361

  529 = 557 . . . . . . . . not true; not a right triangle

__

The longest side (23 mm) is too short for a right triangle, so the angle opposite will be smaller than 90°. This is an acute triangle.

The answer to Your Question in the image is 2/3

2/3=0.6_

Answer:

the slope of the line perpendicular to that line is 6/2

Step-by-step explanation:

Find the slope of the original equation by putting it into y=mx + b form

2x+6y=-4                  Given

2x-(2x)+6y=-4-(2x)   Subtract 2x from both sides

6y= -2x -4                Simplify

6y/6= -2x/6 -4/6      Divide both sides by 6

y= -2/6 x - 4/6          Simplify

*perpendicular slopes are opposite reciprocals*

-2/6 = slope

2/6 is the opposite of -2/6

6/2 is reciprocal of 2/6
