Answer:
Step-by-step explanation:
$50-$20=$30
$30/8= 3.75
since you cannot but 3/4 of a CD you have to round down to 3 to she can buy the phone and 3 CDs and have $6 left over
Answer:
k = 3.022
Step-by-step explanation:
Given that:
A spherical raindrop evaporates at a rate proportional to its surface area.
The surface area SA of a spherical object is given by the relation:
SA = 4πr²
Write down a differ- ential equation for its volume as a function as a function of time.
So; to differentiate Volume (V) in respect to time (t) ;then:
Likewise; we know known that the volume of a sphere V =
Thus, from above;
Thus; solving the differential:
So;
we are to find the constant proportionality K
If Volume V = 1 cm³ and the time = 10 sec
0.1 = - 4π k (0.3848 × 1)
0.1 = - 4π k × 0.3848
4π k = 0.3848/0.1
4π k = 3.848
k = 3.848/4π
k = 3.022
Thanks so muchhhhh have a great evening
4n + 6 - 2n = 2(n + 3)
Simplify.
4n + 6 - 2n = 2n + 6
Subtract 6 from both sides.
4n - 2n = 2n + 6 - 6
Subtract 2n from both sides.
4n - 2n - 2n = 6 - 6
Simplify.
0 = 0
Therefore, there are infinite solutions.
~Hope I helped!~
