Answer:
Step-by-step explanation:
1) Surface area of a square = s*s = 12*12 = 144 in
2) Surface area of a Cone = A=πr(r+h2+r2) = 3.142*4(4+22*2+4*2) = 351.904 cm^2
3) S.A of a Cylinder =2πrh+2πr2 = 2*3.142*2*14 + 2*3.142*2*2 = 201.088 m^2
4) S.A of a square Pyramid = a^2 + 2a squareroot (a^2/4 + h^2) = 516.5m^2
5) S.A of a Sphere = 4*pie*r^2 = 4* 3.142*15^2 = 2827.8mm^2
The company would charge $837.50 to build the fence.
Installing a fence would cost $62.50 per hour.
It will take 13²/₅ hours to install this fence.
The cost would be:
<em>= Cost per hour x Number of hours taken </em>
Number of hours it would take should be converted to improper fraction to be multiplied:
13²/₅ = 67/5 hours
Cost is:
= 62.50 x 67/5
= $837.50
In conclusion, it would cost $837.50 to build the fence.

Answer:
This test batch can be chosen in 2380 ways
Step-by-step explanation:
The order in which the batteries are chosen is not important. So we use the combinations formula to solve this question.
Combinations formula:
is the number of different combinations of x objects from a set of n elements, given by the following formula.

In how many ways can this test batch be chosen?
4 batteries from a set of 17. So

This test batch can be chosen in 2380 ways
