20 A strip of wood 78 inches long can be cut into 20 3 3/4 inch pieces. (78/3.75 = 20.8 Since you can't have a .8 piece of wood, the answer is 20)
Answer:
a. 10 inches
b. 8 inches
c.
Step-by-step explanation:
a. At side 0, perimeter is 0*4 = 0 in. At side 2.5 inches, perimeter = 2.5*4 = 10 inches, a change of 10 - 0 = 10 inches
b. At side 1, perimeter is 1*4 = 4 inches. At side 3 inches, perimeter = 3*4 = 12 inches, a change of 12 - 4 = 8 inches.
c. We can express the change in the square's perimeter P in terms of the change in the square's side length s as
Let us say that this number is n
Then we could say:
<em><u>n - 9</u></em>
Answer:
y=-5/3x+20
Step-by-step explanation:
Let the equation of the required line be represented as
This line is perpendicular to the line
So the equation of the required line becomes
This line passes through the point (15.-5)
So the equation of the required line is
Among the given options, option 4 is the correct one.
