Marc is looking at the plans for his new garage. the length of the garage is 8 metres. the scale on the drawing is 1:50. what will the length of the garage be on the drawing?

Answers

The answer is 16 cm (or 0.16 m).

The scale is the ratio of the model to the real thing.
So, in the scale 1:50, the model is 1, while the real thing is 50.
Now, just make a proportion:
the model : the real thing = the model dimension : the real thing dimension
1 : 50 = x : 8m

From here:
x = 8m * 1 / 50 = 0.16 m = 0.16 * 100 cm = 16 cm.

P=10+3m find p when m =20?

Answers

the equation would become p=10+3×20 then you use PEMDAS and then the answer would be p=70

Hi there! P=10+3m where m=20, of we plug the 20 in we get the equation of P=10+3(20). We use PEMDAS. We don't have any Parenthesis, we don't have any Exponents but we do have Multiplication 3(20), 3(20)=60. Now, we Add 60 by 10, 60+10=70. Therefore, the answer is 60.

You can divide this image into 2 different shapes and there are multiple ways to do this. I drew a line straight down from the side that has a length of 6 to divide the image into 2 rectangles

I now have a rectangle that has sides of 7 and 10 and a rectangle that has sides of 4 and 8

A=L*W so A=7*10 which is 70
A=L*W so A=4*8 which is 32

add these areas together to get 102 so "C" is the correct answer
