Answer:
Step-by-step explanation:
Let 
be the length of the longer side of the smaller rectangle and 
be the length of the shorter side of the smaller rectangle
When you look at the combined rectangle from top to bottom, you can see that 
. Therefore, 
This is the same for 
. Thus, 
When you look from right to left, you can see that 
. Using this, we can represent 
in terms of 
.
Now, we can find the ratio of 
:
<u>This question was quite hard to explain.</u>

<u>Please have a look at the diagram below to get a better understanding of the solution.</u>
Step-by-step explanation:
for a perpendicular,
make x the subject.
8x=11-3y
x=11/8 +3/8
for a perpendicular, the gradient
x= -1/m
x= (-1/11/8) - (-1/3y/8)
x= 8/3y -8/11.
therefore the gradient (m) = 8/3y -8/11.
Answer:
12 sandwiches
Step-by-step explanation:
Make a proportion
He can make 6 sandwiches with 3 tomatoes, and x sandwiches with 6 tomatoes
6/3=x/6
Multiply both sides by 6 to isolate the variable, x
6*6/3=x/6*6
12=x
So, with 6 tomatoes, he can make 12 sandwiches
The answer is An hour and a half
