Starting from what I know (the difference between ribbons), I decided to go from the bottom and work my way up. I then noticed a pattern (each sum was three more of the previous one), and decided to keep my pattern of the three numbers but not have to do any major mental work and instead add three to the previous sum until I got to 38.
Answer:
80 minutes... or an hour and 20 minutes
Step-by-step explanation:
55+25 = 80. an hour is 60 minutes long
Answer:
<h2>h < 2</h2>
Step-by-step explanation:
5(2h+8) < 60
Expand the terms in the bracket
We have
10h + 40 < 60
Group like terms
10h < 60 - 40
10h < 20
Divide both sides by 10
h < 2
Hope this helps you
The equation in spherical coordinates will be a constant, as we are describing a spherical shell.
r(φ, θ) = 8 units.
<h3>
How to rewrite the equation in spherical coordinates?</h3>
The equation:
x^2 + y^2 + z^2 = R^2
Defines a sphere of radius R.
Then the equation:
x^2 + y^2 + z^2 = 64
Defines a sphere of radius √64 = 8.
Then we will have that the radius is a constant for any given angle, then we can write r, the radius, as a constant function of θ and φ, the equation will be:
r(φ, θ) = 8 units.
