52.22 - 39.58 = 12.64
12.64 / 4 = $ 3.16 per shirt
Ans : 2(-2)-3(3)-(-2) = -11
Answer:
Assuming that it's a rectangular track and the units are 15x25 yards, the perimeter is 80 yards.
Explanation:
Remember to find the perimeter of a non-circular shape you just add up all of the side lengths together. In this case, I believe it's a 15x25 yard rectangle, so you ad 15 + 15 + 25 + 25 to get a total of 80 yards.
A single stepping stone as you have said is 20 inches sqaure. This means that it has an area of 20.
All you would need to do then is multiply 20 by 30 to get the area of thirty tiles. The result of this would be 600.
If you mean one side of the stepping stone is 20 inches then you would multiply 20 by 20 to get the area of one, since that would be multiplying length times width (the area formula). The area of one would result in 400 and you would then multiply this by the thirty tiles (400 times 30) to get 12000.
Answer:
B
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 2x + 8 ← is in slope- intercept form
with slope m = 2
Given a line with slope m then the slope of a line perpendicular to it is
= - 
= - 
, thus
y = - x + c ← is the partial equation
To find c substitute (6, - 6) into the partial equation
- 6 = - 3 + c ⇒ c = - 6 + 3 = - 3
y = - x - 3 ← equation of line k
