Answer:
x^2+y^2+z^2-10x-6y-10z +50 =0
Step-by-step explanation:
Given that a sphere is contained in the first octant
Centre of the sphere is given as (5,3,5)
Since this is contained only in the first octant radius should be at most sufficient to touch any one of the three coordinate planes
When it touches we can get the maximum sphere
We find that y coordinate is the minimum of 3 thus radius can be atmost 3 so that then only it can touch y =0 plane i.e. zx plane without crossing to go to the other octants.
Hence radius =3
Equation of the sphere would be
Answer:
9 cm.
Step-by-step explanation:
Let x be the number of hours.
We have been given that after a winter storm, the depth of the snow on cherry street was 10 cm. Then, the snow started melting at a rate of 
, so the snow melted in x hours will be 
.
Since initially there was 10 cm of snow, so the depth of snow after x hours will be:
To find the depth of snow after 3 hours we will substitute 
in our expression.
Therefore, the depth of the snow on cherry street after 3 hours will be 9 cm.

<span>10.1, 20.1 ,
30.1 are the decimal where the value of digit 1/10 had existed.</span>
<span>“Decimal”
comes from the Latin root decem, which simply means “ten.” The
number system we use is called the decimal
number system, because the place value units go in tens: you have ones,
tens, hundreds, thousands, and so on, each unit being 10 times the previous
one.</span>
In common language, the word
“decimal number” has come to mean numbers which have digits after the decimal
point, such as 5.8 or 9.302. But any number within the decimal number system
could be designate a decimal number, involve whole numbers such as 12 or 381.
<span>A Decimal Number (<span>based on the number 10</span>) contains a Decimal Point.</span>
<span>Here is the number "forty-five and six-tenths" written as
a decimal number:</span>
The decimal point goes between Ones and
Tenths.
45.6 has 4 Tens, 5 Ones and 6
Tenths, like this:<span>40+5+6/10</span>
Let M represent the cost of a whiteboard marker.
10(3M + $2.75) = $177.50
3M + $2.75 = $17.75
3M = $15
M = $5
Hence, each whiteboard marker cost $5.
