3, divide by four then subtract six to get three
Answer:
Step-by-step explanation:
The shaded area is the difference of the large and small squares.
<u>Area of large square:</u>
<u>Area of small square:</u>
<u>Shaded area:</u>
- A = A(l) - A(s)
- A = (y + 4)² - y² = y² + 8y + 16 - y² = 8y + 16
4.50 per walk
At least 50
we can write an equation to solve for how many walks, w,
4.50w = 50
divide both sides by 4.50
w = 11.111...
That is, he will have to walk about 12 times to earn at least $50 when charging $4.50 for a walk with the dogs.
Hope this helps :)
Answer:
The third angle of the triangle is 90º
Step-by-step explanation:
A triangle has three interior angles.
The sum of the three interior angles of a triangle is 180º.
In this problem, we have that:
2 angles of 45º
A third angle x
The sum of these angles is 180. So
2*45 + x = 180
90 + x = 180
x = 90º
So
The third angle of the triangle is 90º
D. independent -- Number of Months
dependent -- Total Cost
The dependent Variable depends on the independent variable so, as the number of months change, the total cost changes.
