This isnt something I can do... But draw and label a tape diagram that goes from 0 to 30.
Answer: 55 
feet² or 55.556 feet²
Step-by-step explanation:
The scale means that for ever one in the scale drawing, it is 20 in the actual room. We will convert the dimensions using proportions.
100 = x
-> The length is 100 inches
80 = x
-> The width is 80 inches
The area of a rectangle can be found by multiplying the length by the width:
A = L * W
A = 100 * 80
A = 8,000 inches²
To get this into square feet, we will divide by 144. Why? There are 12 inches in a foot. 12 times 12 is 144.
8,000 inches² / 144 = 55 feet²
The area of the room, in square feet, is 55 feet².
Answer:
Statistical scores and rankings are useful because they provide quantitative figures that represent the student's level of understanding. These methods of ranking can give the observer an opportunity to quickly analyze results but they leave out other factors that are both quantifiable and non-quantifiable. For example, the data won't explicitly convey the time an individual studies but it is compelling to say that good scores and time studying gave a linear relationship. An example of something that is non-quantifiable is the experiences and past knowledge that can affect how well an individual understands and tests on a specific subject.
D over dx (x sin^2(x)) = sin(x) (sin(x) + 2 x cos(x))
385 miles
Step-by-step explanation:
440/16 = x/14
16x = 440 × 14
16x = 6,160
x = 6,160/16
x = 385 miles
