Find the cost per visit to the nearest cent: Health and Heart Club, $259 per year, 3 visits per week. a. $1.66 b. $7.19 c. $156

vagabundo [1.1K]

Answer:

a. $1.66

Step-by-step explanation:

We have been given that Health and Heart Club charges $259 per year. A person has 3 visits per week. We are asked to find the cost of per visit to Health and Heart Club.

We know that there are 52 weeks in one year. So total visits in one year would be 3 times 52 that $156$ visits.

Now, we will divide total cost by 156 to find cost per visit.

$\text{Cost per visit}=\frac{\$259}{156}$

$\text{Cost per visit}=\$1.660256$

Rounding to nearest hundredths, we will get:

$\text{Cost per visit}\approx \$1.66$

Therefore, the cost per visit is $1.66 and option 'a' is the correct choice.

What is the slope of the line that is perpendicular to the line y=1

Crazy boy [7]

Using the slope-intercept form, the slope is 12 1 2 . m=12 m = 1 2.
m=12.
The equation of a perpendicular line to y=x2−6 y = x 2 - 6 must have a slope that is the negative reciprocal of the original slope.
