A study found that 9% of dog owners brush their dog’s teeth. Of 578 dog owners, about how many would be expected to brush their

dog’s teeth? Explain.
1 point
50; 9% ≈ 10% and 578 should be rounded down to 500; 10% of 500 = 50
60; 9% ≈ 10% and 578 ≈ 600; 10% of 600 = 60
70; 9% ≈ 10% and 578 ≈ 700; 10% of 700 = 70
100; 9% ≈ 10% and 578 should be rounded up to 1,000; 10% of 1,000 = 100

Answer:

9 percent of 578 is 52.02.

Step-by-step explanation:

578/x=100/9

(578/x)*x=(100/9)*x       - we multiply both sides of the equation by x

578=11.111111111111*x       - we divide both sides of the equation by (11.111111111111) to get x

578/11.111111111111=x  

52.02=x  

x=52.02

D-1/2=5/12 what is d??
EleoNora [17]

Answer:

d = \frac{11}{12}

Step-by-step explanation:

1) To solve for d, isolate it in the equation. So, to get rid of the -\frac{1}{2} with the d, add \frac{1}{2} to both sides.

d-\frac{1}{2}  = \frac{5}{12} \\d - \frac{1}{2} +\frac{1}{2} = \frac{5}{12} + \frac{6}{12} \\d = \frac{11}{12}

Thus, d = \frac{11}{12}.
