I’m begging for help!! ASAP

This is an awful question. They mean to say the number of hours practicing per week (we'll call it h) varies inversely with the time (t) she runs her event. Unless they mean to imply more practicing makes Tyler slower, in which case she should just get a pizza.

Inverse variation means the product is a constant, we'll call it k.

ht = k

When h = 1 hour t=6 minutes

(1)(6) = k

k = 6 (hour*minutes, but as long as we're consistent we don't need to sweat the unit.)

Decreasing her time by one minute means t = 6 - 1 = 5. We solve for h.

ht = k

h = k/t = 6/5 = 1.2 hours

Answer: 1.2 hours, second choice

Mariana [72]

Answer:

Total number of days in 8 years is 2,922 days.

Step-by-step explanation:

Number of days in a Normal year = 365 days

Number of days in a leap year = 366 days

Also, Leap year comes exactly ONE TIME in every FOUR YEARS.

⇒ In every consecutive 4 years, 1 year is a leap year.

⇒ So, number of leap years in 8 years = 2

Now, 8 Years = 6 Normal years + 2 leap Years

Number of days in 6 normal years

= 6 x ( Number of days in a regular year)

= 6 x (365 days) = 2,190 days

Number of days in 2 leap years

= 2 x ( Number of days in a leap year)

= 2 x (366 days) = 732 days

So, Total number of days in 8 years

= Number of days in 6 regular years + Number of days in 2 leap years

= 2,190 days + 732 days

= 2,922 days

Hence, total number of days in 8 years is 2,922 days.
