The statement that is sometimes, but not always true is:
B ) A parallelogram is a rectangle.
Other statements are always true.
Answer:
Step-by-step explanation:
As with all word problems we first have to convert it to an equation or equations.
L = length of the Rectangle and W = its width
So L = 2 * W
A = area of the rectangle which is 128 cm^2
So A = L * W = 128 cm^2
substitute 2W for L from the 1st equation to give A = 2 * W * W = 2 * W^2 = 128 cm^2
Thus W^2 = 64 cm^2
finally W = 8 cm and therefore L = 2 * W = 16 cm
The perimeter P = 2 * (L+W) = 2* (8cm + 16cm) = 2 * 24cm = 48 cm
Answer:
D
Step-by-step explanation:
Answer:
P = 24.135 pounds per square inch
Step-by-step explanation:
The air pressure in the tire should be 
pounds per square inch. This pressure is in the form of a mixed fraction. It is required to convert this pressure into a decimal form. We can convert it as follows :
In decimal form, the value of pressure in the tire on the digital pressure gauge is 24.135 pounds per square inch.
X/4y = 16/4(2) = 16/8 = 2
