A designer builders a model of a bicycle the finished model is exactly the same as the original but smaller. The scale factor is 2:15 (A) ratio of height ☑️:☑️ (B)surface area ☑️:☑️ (C)volume ☑️:☑️

Answers

Answer:

a) The ratio of height is 2:15

b) The ratio of surface area is 4:225

c) The ratio of volume is 8:3375

Step-by-step explanation:

The scale factor of model to original is 2 :15

Please remember the concept, when scale factor is a:b

Then ratio of sides would be same a:b

The ratio of surface area is [tex]a^{2} :b^{2}[/tex]

The volume is [tex]a^{3} :b^{3}[/tex]

According to the concept,

The ratio of height is 2:15

The ratio of surface area is [tex]2^{2} :15^{2}[/tex] =4:225

The ratio of volume is [tex]2^{3} :15^{3}[/tex] =8 :3375.

Three of the four vertices of a rectangle are located at (4, 2), (7, 2) and (4, 8). a. What are the coordinates of the missing vertex? ( , ) b. Find the area and perimeter of the rectangle. Area = square units Perimeter = units

Answers

Answer:

a) The coordinates of the missing vertex = (7, 8)

b) Area = 18 square units

   Perimeter = 18 units

Step-by-step explanation:

a) We know three of the four vertices:

A: (4, 2)           C ______ D(?)

B: (7, 2)               |             |

C: (4, 8)           A |______| B  

To find the coordinates of the missing vertex we need to calculate the distance in the x-direction from point A to point B:

[tex] B_{x} - A_{x} = 7 - 4 = 3 [/tex]                    

Hence, the distance of point D from point C in the x-direction is:

[tex] D_{x} = C_{x} + 3 = 4 + 3 = 7 [/tex]

Now, to find the coordinate in "y" we need to calculate the distance in the y-direction between point C and point A:

[tex] C_{y} - A_{y} = 8 - 2 = 6 [/tex]  

Then, the distance of point D from point B in the y-direction is:

[tex] D_{y} = B_{y} + 6 = 2 + 6 = 8 [/tex]

Therefore, the coordinates of the missing vertex (point D) are:

[tex] D = (D_{x}, D_{y}) = (7, 8) [/tex]    

b) The area of the rectangle is:

[tex] a = (B_{x} - A_{x})*(C_{y} - A_{y}) = 3*6 = 18 units^{2} [/tex]

The perimeter is given by:

[tex] p = 2*(3 + 6) = 18 units [/tex]

I hope it helps you!

HELP ME ASAP BRAINLY :)) How many sides does a polygon have if its total interior angle sum is 4 times its total exterior angle sum?

Answers

Answer:

Step-by-step explanation:

If you are given the interior angle, just subtract that from 180 to get the exterior angle and then use the number of sides = 360 / exterior angle to find the number of sides. it's much easier. the number of sides is equal to 10. the sum of the interior angles is equal to 10 * 144 = 1440 degrees.
10 x 144 so that would be 1440

x = 7

Step-by-step explanation:

Given

3x - 5 = 16 ( add 5 to both sides )

3x = 21 ( divide both sides by 3 )

x = 7

Answer: X= 7

Explanation:
(you need to get x by its self)

Step 1- add the (-5) over to the 16

Because to get rid of a negative or minus sign you need to do the opposite which is addition.

You’ll get: 3x=21

Step 2- divide the 3 off from 21
Because the ‘3x’ is acting as multiplication, and the opposite of multiplication is division

You’ll get: X=21/3
Which is X=7
