Answer:
When your counting money and have cents to add up you would make the number a decimal for example if you have 25 dollars and 36 cents it would be $25.36. Or same thing if you owe money
Step-by-step explanation:
It would be a composite number. A prime number is defined as a number that can be divisible only by 1 and itself. If the length of any of the sides of the rectangle are any number other than 1, then it must also be divisible by that number - therefore the figure of the area cannot be a prime number.
<u><em>Answer:</em></u>
<em><u>Step-by-step explanation:</u></em>
So if she makes 6dollars an hour then:
she would make 18 dollars a day, and she would make 54 dollars a week then she would make 564 dollars a summer
<u><em>if she make 6 dollars a day then: </em></u>
She would do 6x3 and she would make 18 dollars a week and 198 over the summer
Whooh
SA=4pir²
take derivitive
dSA/dt=8pir dr/dt
and do the volume as well
V=(4/3)pir³
dV/dt=4pir² dr/dt
we need to solve for dV/dt
to do taht we need dr/dt
so
dSA/dt=8pir dr/dt
given dSA/dt=3pi cm/sec
r=2
3pi=8pi2 dr/dt
3=16 dr/dt
3/16=dr/dt
now do the volume
dV/dt=4pir² dr/dt
r=2
dr/dt=3/16
dV/dt=4pi2² (3/16)
dV/dt=16pi(3/16)
dV/dt=3pi
nice
the volume of the sphere is decreasing at 3pi cm/sec as well
