Before i try and answer this do u have a graph
Convert 79% to a decimal which is .79
Then you multiply .79 by 32 which is 25.28
Your answer is 25.28
Answer:
Step-by-step explanation:
Let the number of hours Nick does the job alone to be x - 3 hours
Hence, in 1 hour, Nick has done 1/x - 3
Together they complete the job in 9 hours
Hence, let's represent the job as 1
9/x + 9/x - 3 = 1
Multiply through by (x)(x-3)
9(x- 3) + 9(x) = 1
9x - 27 + 9x = (x)(x-3)
-27 = x² - 3x
x² - 3x +27 = 0
A because the 6 and 3 cancel out
Then 2 x 8 is (16) and 15 x 5 is (75)
Making it A
8x5 = 40
3x2 = 6
40 - 6 = 34
answer:
area of shaded = 34
