In a college parking lot, the number of ordinary cars is larger than the number of sport utility vehicles by 42.9%. the differen
fenix001 [56]
Let
 x = number of common cars
 y = number of suvs
 we can write the following system of equations
 x-y = 12
 x = 1.429y
 Solving the system we have
 x-y = 12
 1.429y-y = 12
 and (1,429-1) = 12
 y = (12) / (1,429-1) = 27.97202797
 then,
 x = 1429 * (27.97202797)
 x = 39.97202797
 answer
 The number of suvs in the parking lot is 28

a silo is shaped like a cylinderwith a cone on top. the radii of the bases of the cylinder and cone are both equal to 8 feet. th
Ymorist [56]

Answer:

5430.85 square feet

Step-by-step explanation:

Height of the cylindrical part of the cilo   = 25 feet

radius of the base cylindrical part of cilo = 8 feet

Now volume of cylindrical part of cilo =\pi r^{2} h

Volume of cylindrical part of cilo = \pi(8^{2})25 = 1600\pi square feet

Now,

Height of the conical part of cilo = 6 feet

Radius of the conical part of cilo = 8 feet

Volume of the conical  part of cilo = \frac{1}{3}\pi (8^{2})6= 128\pi square feet

Volume of the entire cilo = 1600\pi + 128\pi = 1728\pi

since \pi =\frac{22}{7} therefore,

volume of entire cilo =   \frac{22}{7} (1728)= 5430.85
