The reasonable measurement is D.)the distance from New York to California is 2,250 miles
Measurement:
Measurement is the process of comparison of an unknown quantity with a known or standard quantity.
Given,
Mr. Customs is correcting the class’s math homework on customary units. Here we need to find which of the following measurements is reasonable.
By looking at the given options,
A) a pencil is 12 feet long - This one is wrong because the measuring unit of pencil is cm.
B) the back porch is 12 inches wide - For this one we have to use the feet or meter scale.
C) the 3rd hole in the golf course is is 123 miles long - Here this one we have to use either cm or mm.
Therefore, option (D) the distance from New York to California is 2,250 miles is a reasonable statement.

Answer:
34.5p-2.75
Step-by-step explanation:
First add -0.5p and 12p together which is 11.5p, then add 23p with 11.5p which is 34.5p And -2.75 remains the same
So the answer is 34.5p-2.75
If you cut the rectangle (the wall) diagonally, you get two congruent triangles. The measurements of the sides of one the triangles is 8, 15 and x. There is a pythagorean triples 8, 15, 17 so x has to be 17. if you dont know the triple you can do a^2 + b^2 = c^2 8^2 + 15^2 = c^2 c = 17
the diagonal of wall should be 17
ok you need formula for surface area.
SA = πrh+2πr^2
Plug in 25 and 5
SA = 2π(5)(25)+2π(5)^2
SA = 10pi*25 + 2pi(25)
SA = 250pi + 50pi
SA = 300pi
Hope this helps :)
