Answer:
13 inches
Step-by-step explanation:
Use the formula P = 2l + 2w to find width.
80 = 2(27) + 2w
80 = 54 + 2w
80 - 54= 2w
26 = 2w
w = 26/2
w = 13
The width of the rectangle is 13 inches.
Answer:
C
Step-by-step explanation:
the size of the steps gives you the number before x
and the -1 , +4 is just what left when x equals zero, so in the two tables we find it in row two
You need to substitute x with a #
6 (-3)+6=-12
Answer:
![30-3d\leq 20](https://tex.z-dn.net/?f=30-3d%5Cleq%2020)
Step by step explanation:
Let d represent the rate of temperature decrease in degrees Celsius per day from Monday to Thursday.
As temperature decreased at a constant rate in the next 3 days, so the rate of temperature will decrease 3d degree Celsius in 3 days.
We are told that the pool was open on Monday. The high temperature was
on Monday. So the decrease in temperature from Monday to Thursday will be
.
We have been given that the swimming pool is open when the high temperature is higher than
.
As the pool was closed on Thursday. This means that temperature on Thursday was less than or equal to 20 degree Celsius. We can represent this information in an inequality as:
![30-3d\leq 20](https://tex.z-dn.net/?f=30-3d%5Cleq%2020)
Therefore, the inequality
can be used to determine the rate of temperature decrease in degrees Celsius per day, d, from Monday to Thursday.
