Answer:
Total weight = 70.5 kg
Step-by-step explanation:
Rectangular frame is made from 5 straight pieces of metal. One of them goes through the diagonal of the rectangle.
2 pieces form the length of the rectangular frame, hence, they have a length of 12 m each
2 pieces from the width of the rectangular frame, hence, they a length of 5 m each
To find the length of the diagonal, we can use Pythagoras Theorem:
Hypotenuse² = Base² + Perpendicular²
Hypotenuse² = 5² + 12²
Hypotenuse² = 169²
Hypotenuse = 13
Hence, the length of the piece of metal placed at the diagonal is 13cm
Find the sum of all lengths of the metal pieces.
Total length = 12 + 12 + 5 + 5 + 13
Total length = 47 m
Total weight = 1.5 × Total length
Total weight = 1.5 kg/m × 47m
Total weight = 70.5 kg
Answer:
I think the second option is the most appropriate option.
Step-by-step explanation:
Mikhail believes he can use the multiplication expression 
to find the total number of pound servings of rice he can make from 6 pounds of rice.
Now, we have to select the statement from the four options that best explains why Mikhail is correct or incorrect.
I think the second option is the most appropriate option.
So, Mikhail is correct in using a multiplication expression because 1/2 is the number of servings per pound. (Answer)
