s = hours it takes the small pipe on its own.
L = hours it takes the large pipe on its own.
we know the small pipe can do it in 11 hours total, so s = 11, so, how much of the whole job has the small done in 1 hour only?
well, if it takes 11 hours to do the whole thing, in 1 hour it has done only 1/11 of the whole job.
we know both pipes working together can do it in 6 hours flat. So in 1 hour only, both of them have done only 1/6 of the whole thing.
in that 1 hour, how much has the large one done? well, it has only done 1/L of the job.
and you can round that up as needed.
Answer:
A) The graph shifts 5 units left and 3 units up.
Step-by-step explanation:
For a function 
following transformation rules is applied.
shifts function 
units to the right.
shifts function units to the right.
shifts function units upward.
shifts function units down upward.
Given function :
Function 
:
So, to transform to we can make changes as
Comparing the two function we conclude the following transformation taking place:
From the above rule stated, we can make a statement about the transformation as following:
The graph shifts 5 units left and 3 units up.
Answer:
6.30$
Step-by-step explanation:
1.80x3=5.40
1.80/2=0.90
5.40+0.90=6.30
hope it helps!
Answer: the ratio of the perimeters = 7/9
the ratio of the areas = 47/81
Step-by-step explanation:
The scale factor of the two triangular mats is 7 / 9. Expressing it in terms of decimal fraction, it becomes 0.778
Perimeter is the total distance around the triangle. It is determined by simply adding the length of each sides. Therefore it is a linear measurement. Therefore, the ratio of the perimeter of both triangles will remain 7/9 or 0.778
The area of the triangle is not a linear measurement. Determining the area of the triangle involves multiplication of the different lengths by applying the desired formula. The ratio of the areas of both triangles will be (7/9)^2 = 47/81
