Answer:
12 INCHES = 1FOOT
Step-by-step explanation:
Let the segment be represented by AB where A(0,0) =
and B(3/4,9/10) =
.
The length of the segment drawn by architect can be calculated using distance formula:
AB =



Similarly, Let the actual end points of segment be AC where A(0,0) =
and C(30,36) =
.
The length of the original segment can be calculated using distance formula:
AC =


.
Thus, the actual length is 40 times the length of the segment drawn by the architect.
Thus, the proportion of the model is 1:40
Answer:
x²y² - z²
Step-by-step explanation:
Note that
(xy + z)(xy - z) are the factors of a difference of squares
a² - b² = (a + b)(a - b)
here a = xy and b = z, thus
(xy + z)(xy - z) = (xy)² - z² = x²y² - z²
Answer:
x=1/2
Step-by-step explanation:
convert: 23/2+1/4=6
multiply each sides by 4: 46x+=24
substract: 46x=33
divide: x=1/2
