Hello, and thank you for posting your question here on brainly.

We have a trick in my school named "the cupid rule", where if you're subtracting a negative that's in parenthesis, we put a ♥ over the two negatives, and turn it into a positive, so now it's 7 + 15.

(it's 22)

Hope this helps! ☺♥

inna [77]

Answer:

0.2 hours

Step-by-step explanation:

The depth, d of snow (in cm) that accumulates in Harper's yard during the first h hours of a snowstorm can be calculated using the equation:

d=5h

When d=1cm, we want to determine the value of h.

1=5h

h=1/5=0.2

Therefore, it takes 0.2 hours for 1 centimeter of snow to accumulate in Harper's yard.

Answer:

$\huge\boxed{ 12\ people}$

Step-by-step explanation:

At least 6 hours means that the people took at least 6 hours and at most any number that is greater than 6. Here the greatest no. is 10.

<em><u>So, the range for this will be 6-10</u></em>

No. of People who sleep for 6-8 hours = 9

No. of People who sleep for 8-10 hours = 3

No. of People who sleep for 6-10 hours = 9+3

=> 12 people
