Answer:
81 is the scale of drawing.
Step-by-step explanation:
Area of the house in drawing = A =
Let the factor by which scaling is present in the drawing be s.
Area of the house in reality = A' =
Here we are supposed to find the distance between the two points
Suppose A=(-8,-9), B=(-4,-10)
Now As per the distance formula we know that the distance between two points is given by the formula
Perimeter of circular area = πr = 3.14 * 10 = 31.4 mm
Perimeter of rectangular area = 30 + 20 + 30 = 80 mm
Total Perimeter = 80 + 31.4 = 111.4
In short, Your Answer would be 111.4 mm
Hope this helps!
Answer:
3 students are eating lunches other than salads and sandwiches.
Step-by-step explanation:
To solve this you know that there are 18 students in the cafeteria and 1/6 of them are eating salads and 2/3 are eating sandwiches right? So you would have to think about what 1/6 of 18 is so you know how many students are eating salads, and 1/6 of 18 is 3 so there are 3 students eating salads. Now, you have to find out how many students are eating sandwiches, so you need to know what 2/3 of 18 is. 2/3 of 18 is 12 so now you also know that there are 12 students eating sandwiches. Next, you have to add 12 and 3 and you get 15. Since you know that there are 18 students in the cafeteria, you have to subtract 18 by 15, and you should get 3. So 3 students are eating lunches other than salads or sandwiches.
Hope this helps you! :D
