y = 0.75 + 1 → B
increasing at 0.75 in/min , thus 0.75x after x min
The depth is already at 1 in
y = 0.75x + 1 is the equation.
Use the formula (n - 2) * 180 to find the sum of the interior measures of a polygon.
n stands for the number of sides that the polygon has, so substitute 10 for n since a decagon has 10 sides.
(10 - 2) * 180, start by solving inside the parentheses and subtracting 10 and 2.
(8) * 180, multiply.
B. 1,440 is your answer.
To find the rate, divide the number divided by the amount of minutes. So 775 divided by 12.5 which is 62.
62 steps per minute
-- Both pairs of sides of a rectangle are parallel.
Only one pair of sides of a trapezoid are.
-- A rectangle is a parallelogram.
A trapezoid isn't.
-- The opposite sides of a rectangle are equal.
The opposite sides of a trapezoid aren't.
-- All of the angles of a rectangle are right angles.
The angles of a trapezoid aren't.
-- The area of a rectangle is the product of (length) times (width).
The area of a trapezoid is (height) times (the average of the two bases).
