Part A: 47 x 38 + 47 x 62. You have to do your order of operations first. 47 x 38 is 1786. 47 x 62 is 2914. 2914 + 1786 is 4700, your answer.
Part B: 752 + (467+248) = 752 + (715)=1467.
Answer:
Length of spaceship in movie = 528
Step-by-step explanation:
Given that:
Drawing ratio of spaceship = 1 : 24
It means that 1 inch on drawing equals 24 inches in movie
Drawing of spaceship = 22 inches
Length of spaceship in movie = x
As the relationship is proportional,
1 : 24 :: 22 : x
Product of mean = Product of extreme
24*22 = x
x = 528
Hence,
Length of spaceship in movie = 528
Since there are 10 pencils, and 2 erasers, the ratio of pencils to erasers is 10:2. You can divide both sides by 2 to get 5:1.
