Answer:
The answer is 50
Step-by-step explanation:
2+3=5
10 times 5= 50 (your answer)
The ratio of pop songs to rock songs you download is 5:4, and 40 are pop songs. You want to find out how many rock songs there are.
First, add the ratios together: 5+4=9. This means that 9 will be your denominator, so 5/9 songs are pop and 4/9 songs are rock.
Now you know that pop songs account for 5/9 of the songs, this means that 40 is 5/9 of the total songs.
To find out how much 4/9 is, you need to divide 40 by 5 to get 1/9 and times that number by 4 to get 4/9:
40÷5=8×4=32 songs are rock songs

*Hint: The formula for finding the surface area of a rectangular prism is SA = 2 (wh + lw + lh).
Now, just plug in and solve.
SA = 2 [(10)(8) + (12)(10) + (12)(8)]
SA = 2 (80 + 120 + 96)
SA = 2 (296)
SA = 592.
The surface area of Rita's room is 592 feet squared.
