We can calculate the depth d of snow, in centimeters, that accumulates in Harper's yard during the first h hours of a snowstorm using the equation d=5h. How many hours does it take for 11 centimeter of snow to accumulate in Harper's yard? How many centimeters of snow accumulate per hour? centimeters

Answers

Answer:

2.2 hours takes to accumulate 11 centimeter of snow in Harper's yard and snow accumulate per hour is 5 cm.

Step-by-step explanation:

Given:

d = 5h

where d is depth of snow in centimeters and h is hours of a snowstrom.

To find: Time when the depth of snow is 11 cm.

             Depth of snow accumulate per hour.

Consider,

d = 5h

put d = 11

11 = 5h

h=(11)/(5)

h = 2.2 hours

h = 2 hours 12 minutes

Now, Put h = 1

d = 5 × 1

d = 5 cm

Therefore, 2.2 hours takes to accumulate 11 centimeter of snow in Harper's yard and snow accumulate per hour is 5 cm.

Answer:

  1. How many hours does it take for 11 centimeter of snow to accumulate in Harper's yard? 2.2 hours which is 2 hours 12 minutes
  2. How many centimeters of snow accumulate per hour? 5 centimeter

Step-by-step explanation:

We know, that d means depth. Also, we know that h means hour.

d=5h basically means this: depth is equal to 5cm times hours

We have to questions to answer here. We already answered the second question. To answer first question, we just divide 11/5 ...That is 2.2 hours. That is 2 hours and 12 minutes.

  1. How many hours does it take for 11 centimeter of snow to accumulate in Harper's yard? 2.2 hours which is 2 hours 12 minutes
  2. How many centimeters of snow accumulate per hour? 5 centimeter

192 rounded to nearest tenth?

Answers

There is no TENTH in 192 so 192 rounded to the nearest TENTH is 192.


If you meant TEN then 192 rounded to the nearest TEN is 190.

Good Luck!

The next larger tenth is 192.1

The next smaller tenth is 191.9

But 192 is closer to 192 than it is to 192.1 or 191.9, so 192 is ALREADY rounded to the nearest tenth.
