You need to find what 11% of 4 2/5 is.
You can convert 4 2/5 to 4.4 and 11% to .11
Then just multiply them together
4.4 * .11 = your answer
Answer:
We are given that:
variables x and y vary directly, this means that:
y = kx where k is the constant of proportionality
Now, we are also given that:
y = 45 at x = 40.
We will use these values and substitute in the above relation to get k as follows:
y = kx
45 = 40k
k = 45/40 = 9/8 = 1.125
Based on the above calculations, the equation that relates x and y is:
y = 1.125x
Step-by-step explanation:
Answer:
If the kid walks for the dotted line, the distance is 36ft.
Now, you can see that this is a triangle rectangle, then we must have that:
x^2 + (x + 6)^2 = 36^2 (the Pythagorean theorem)
Now we must solve this for x.
x^2 + x^2 + 2*6*x + 36 = 36^2
2*x^2 + 12*x -1260 = 0
The solutions for this equation are:
the solutions are:
x = (-12 - 101.1)/4 = -28.78
x = (-12 + 101.1)/4 = 22.3
Then we have x = 22.3 ft
The lenght of the path following the cathetus is:
D = x + x + 6 = 2*22.3ft + 6ft = 50.6ft
Then the difference between the distances is:
Diff = 50.6ft -36ft = 14.6ft

Answer:
Option A
Step-by-step explanation:
Let's denote:
x is the number of albums Teresa downloads.
y is the number of individual songs Teresa downloads.
=> 9x + y = 25
Let's check:
Option A: x = 2 and y = 7 => 9 x (2) + 7 = 18 + 7 = 25 => valid
Option B: x = 1 and y = 8 => 9 x (1) + 8 = 9 + 8 = 17 => invalid
Option C: x = 4 and y = 5 => 9 x (4) + 5 = 36 + 5 = 41 => invalid
Option D: x = 3 and y = 6 => 9 x (3) + 6 = 27 + 6 = 33 => invalid
