Answer:
length = 115 cm
width = 108 cm
Step-by-step explanation:
The perimeter of a rectangular swimming pool is 446 centimeters
LEt L be the length of the pool
The width of the pool is 7 centimeters less than the length of the pool.
width = length - 7
W= L-7
Given perimeter = 446
Perimeter of rectangle = 2(length)+2(width)
446 = 2(L) + 2(W) we know W = L-7
446 = 2(L) + 2(L-7)
446 = 2L + 2L - 14
Add 14 on both sides
460 = 4L
divide by 4 on both sides
L= 115
Length L= 115
Width W = L - 7 = 115 - 7= 108
Answer:
The correct answer should be A not 100% sure
Answer:
90 degree angles (perpendicular bisector of the line)
Answer:
see the procedure
Step-by-step explanation:
we know that
The scale factor of the model is 1/30
That means ----> 1 unit in the model represent 30 units in the actual
so
using proportion
Find out how much represent 5 ft in the model
Convert feet to inches
Remember that

so

Let
x -----> the diameter of the circular window in the model house in inches

Simplify

therefore
The diameter of the circular window in the model house is 2 inches
