B does. Use the like test!
B. the temperature change between noon and 6 PM is the same as the temperature change between 8 PM and 10 PM.
You will use the Pythagorean Theorem to find the length of the walkway.
A diagonal across creates 2 congruent triangles which are right triangles.
a^2 + b^2 = c^2
12^2 + 9^2 = c^2
144 + 81 = c^2
225 = c^2; find the square root of 225
c = 15 meters
The length of the walkway is 15 meters.
Answer:
See below.
Step-by-step explanation:
Find the area of the rectangle using A = l*w = 26*20 = 520.
Now find the area of the semi circle using A = 1/2 πr². Since the instructions do not say the diameter of the semi circle assume it is 20 or 26.
If it is 20: r = 10 and the area is A = 1/2 π10²=50π = 157.
If it is 26: r = 13 and the area is A = 1/2π13² = (84.5)π = 265.33.
The area of the paperboard that remains will be the area of the rectangle minus the area of the semi circle.
If the diameter of the semi circle is 20 then 520 - 157 = 363.
If the diameter of the semi circle is 26 then 520 - 254.67.
