Match the description to the best example so that all terms have a matching example.

1-e

2-b

3-c

4-q

5-d    

Step-by-step explanation:

In this question, we have to match the left hand side to corresponding right hand side. On the right side we are given

a){3,4,5}

b){0,1,2,3}

c){-2,-1,0,1}

d){, , }

e){0.1, 0.2, 0.3}

1) a set of decimal numbers:

It is clear the the set of decimal numbers is e) {0.1, 0.2, 0.3}

2) a set of whole numbers is b) {0,1,2,3}

3) a set of integers is c)  {-2,-1,0,1}

4)  a set of natural numbers is a) {3,4,5}

5) a set of rational numbers is d) {, , }

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.

answer: the resulting cross section is a rectangle. solution: a plane parallel to the base of a triangular prism will intersect a cross section that is the same shape as its bases. so the cross section is a triangle.
