Well, in the store, when you buy something, there are decimals, also, speed limit for your car, and time, but that is not an exact thing for this question, because 60 can't be a decimal. you cant make it so you can show 60 seconds as a decimal without an irrational number. sometimes, the number just goes on forever.
Answer:
okie dokie
Step-by-step explanation:
Part A:
Express the given number of hours and velocities of the cyclist as ordered pairs. The time (number of hours) can be our abscissa (x-coordinate) and the velocities can be our ordinate (y-coordinate). The coordinates are therefore (2, 18) and (4, 4). The equation that can be formed in this is established through the two-point equation.
(y - y₁) = ((y₂ - y₁)/(x₂ - x₁))(x - x₁)
Substitute the known variables.
(y - 18) = ((4 - 18)/(4 - 2))(x - 2)
Simplifying the equation,
y - 18 = -7(x - 2)
y = -7x + 32
<em>ANSWER: y = -7x + 32
</em>Part B: This can be graph in the Cartesian plane and numbers 1 to 8 can be substituted to y and take note of the ordered pairs for each point. The slope of the line should be -7 and the y-intercept is 32.<em>

Answer:
diameter of semicircle? ---> 30cm
perimeter- pi*r ----> 3.14159265 x 15 ---->47.12 cm
Step-by-step explanation:
Answer:
V = 8491 mm^3
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2 h
We know the radius is 13 and the height is 16
V = pi * (13)^2 *16
V = 169*16 *pi
V =2704 *pi
Let pi be approximated by 3.14
V =2704(3.14)
V =8490.56
To the nearest whole number
V = 8491 mm^3
