Answer:
168.75π cm^3 is your answer.
Volume of a cone is 1/3 πr^2h.
Here, radius is given 7.5cm and height is given 9cm. So by using the formula we get the above answer.
Answer:
1.5 inches
Step-by-step explanation:
(10+2x)(14+2x) = 221
4x² + 48x - 81 = 0
4x² + 54x - 6x - 81 = 0
2x(2x + 27) - 3(2x + 27) = 0
(2x + 27)(2x - 3) = 0
x = -27/2, 3/2
x = 3/2 or 1½ or 1.5 inches
Hi. You could easily find the slope-intercept form equation if you plot the points and do data fitting. You can use this with a software like MS Excel. The figure is attached in the image. Hence, the equation is y = 33x + 132, where y is the number of riders and x is the number of hours of Tara's shift.
The number of half page advertisements that Michael purchased is 4 while the full page advertisements is 11.
Let the number of half page ads be represented by h
Let the number of full page ads be represented by f.
Total number of advertisements = 15
h + f = 15 ....... (i)
h = 15 - f
Therefore, the system of equations to represent the situation will be:
60h + 100f = 1340 ........ (ii)
Put the value of h into equation (ii)
60(15 - f) + 100f = 1340
900 - 60f + 100f = 1340
Collect like terms
100f-60f = 1340-900
40f = 440
f = 11
The number of full-page advertisements that Michael purchased is 11.
Since h + f = 15
h + 11 = 15
h = 15 - 11
h = 4
The number of half page advertisements that Michael purchased is 5.
