Answer:
$11.31
Step-by-step explanation:
$14.50x .22= 3.19
$14.50- 3.19= 11.31
The cost depend on the number pencils, so the cost is the y and # of pencils is the x
Same as for question 7
To graph, the length depend on the time, so length is y, time is x
6. Linear
7. Not
Expand the right side:


Notice that 98 = 2 * 7 * 7, so we have
and
.
Then

and

Volume of a cone is equal to pi*r^2*(h/3)
3.14*5^2*2/3 = 52.36 cubic cm.
Density = mass/volume
6 grams/ 52.36 cm^3= 0.1146
Round to 2 decimal places to get D.0.11 g/cm^3
