Answer: 40.5 square feet
Step-by-step explanation:
Given : Zhi needs new flooring for her two laundry rooms.each room is 4.5 feet long and 4.5 feet wide .
We assume that the room is rectangular in shape .
Area of rectangle = Length x width
Then area of one laundry room = 4.5 feet x 4.5 feet = 20.25 square feet
Area of two laundry room = 2 x 20.25 = 40.5 square feet.
Hence, The flooring need to cover a total of <u>40.5 square feet</u> of area.
Answer:
I believe the answer is 30.
Step-by-step explanation:
The answer is 7 meters.
Area is (pi)r^2
If we remove pi, we have 49=r^2
This means that r=7

Answer:
C. y = -2/3x +22/3
Step-by-step explanation:
You can choose the correct answer by realizing that the line must have a y-intercept greater than 6. The given point is (2, 6) and the line goes up and to the left from there. The y-intercept is obviously more than 6.
The only reasonable answer choice is ...
y = -2/3x +22/3 . . . . . a y-intercept of 7 1/3
_____
There are a lot of ways to work problems like these. One is to write the equation of the line, then match that to the answer choices.
Another is to eliminate all the "impossible" answer choices, then choose the appropriate one from what's left. (The given line has a negative slope, eliminating choices A and B.)
I like to use the simplest method that will determine the correct answer. Here, that involves reading and understanding the question to obtain some idea of where the desired line must appear on the graph.
Of course, it helps to know that "slope-intercept form" is ...
y = mx +b . . . . . . m represents the slope; b is the y-intercept
