Answer:

$(-\infty,\frac{25}{24}]$

Step-by-step explanation:

Assuming $i$ is a variable:

$4i-4(i+2)\geq6(8i-8)\\\\4i-4i+2\geq48i-48\\\\2\geq48i-48\\\\50\geq48i\\\\\frac{50}{48}\geq i\\ \\\frac{25}{24}\geq i\\ \\i\leq\frac{25}{24}\\ \\(-\infty,\frac{25}{24}]$

ale4655 [162]

Answer:

72 doctors recommended the medicine

Step-by-step explanation:

The question above is interpreted thus.

9 out of 10 implies 9/10. If 80 doctors were surveyed, the number of doctors that recommended the medicine is 9/10 of 80 doctors. Therefore,

$\frac{9}{10} \: of \: 80$

$= \frac{9}{10} \times 80$

$= \frac{9 \times 80}{10}$

$= \frac{720}{10}$

$= 72$

Therefore, in a survey where 9 out of 10 doctors recommended a certain medicine; and 80 doctors were surveyed, 72 doctors recommended the medicine.

What is another way to find the total cost. of shoes for $57 with a sales tax of 2%?

Alekssandra [29.7K]

Hey there!

Make the 2% to a decimal which is .02 and multiply it by 57 to find the sales tax

.02*57= 11.4
So 11.4 is the sales tax
So add 11.4 to 57 and you get

$68.40 is the total cost

Hope this helps!
