Find the perimeter of a picture first.
width = 7 1/2 = 15/2 in
length = 8 in
perimeter = 2(width) + 2(length)
p = 2(15/2) + 2(8)
p = 15 + 16
p = 31 in
next, find the perimeter of border.
p = 4(1 1/4)
p = 4(5/4)
p = 5 in
perimeter of picture with border = 31 + 5 = 36 in
Answer:
c) It can be equal to 1.00 but it can also be greater than 1.00. It is never less than 1.00.
Explanation:
Refractive index is equal to velocity of the light 'c' in empty space divided by the velocity 'v' in the substance.
Or ,
n = c/v.
Since speed of the light 'v' in any medium is always be less than or equal to speed of the light in the vacuum 'c', thus, the index of refraction is always be greater than or equal to 1.0.
Step-by-step explanation:
To find out how far Rachel walked round trip, we first need to find out how long the fastest way between her house and the park is. In the picture, we see a common Pythagorean Triple (the possibility for the sides of a right triangle). The triple with 3 and 4 is 3, 4, and 5. That means that the last side is 5. That means that the total distance is 3 + 4 + 5 km or 12 km. But, if you would like to solve this using the Pythagorean Theorem, one can do it as follows. Since the legs of the triangle are 3 and 4, the hypotenuse squared would be 3² + 4² = 9 + 16 = 25. To find the hypotenuse, we have to find the square root of 25 which is 5, which leads us to the same answer as before.
905 pounds is greater than grams.
Hope this helps (:
