Answer:
$49.50
Step-by-step explanation:
You take the $45 and multiply it by 10% (tax). That comes out to $4.50. Then, you take the $45.00 (grocery bill) and add it to $4.50 (10% tax)
$45.00 + $4.50=$49.50
D
7 minutes for 49 gallons
that means 1 minutes filled 7 gallon
multiply the time by 7, that is number of gallons for each time
Answer:
t = 2.5 s
Step-by-step explanation:
h(t)=-16t^2 +80t+96
height will be greatest when the derivative (velocity) is zero
h'(t) = v(t) = -32t + 80
0 = -32t + 80
32t = 80
t = 80/32 = 2.5 s
notice that 0 = -32t + 80 is just a version of the kinematic equation
v = u + at
where v is final velocity at the top of the arc or zero
u is the initial upward velocity or 80 ft/s
a is gravity or -32 ft/s²
t is time in seconds
Subsitute for s and do the arithmetic.
.. A = 54s²
.. A = 54(1/3)² . . . . put 1/3 where s is
.. A = 54(1/9)
.. A = 6 . . . . . . square units
Answer:
1 book = 41 dollars.
Step-by-step explanation:
If you divide your whole by your part, then you will get how much 1 book is.
how i did it:
246 divided by 6 = 41.
1 book = 41 dollars
