The universal set is the set of rational numbers. S is the set of integers. Which represents Sc?The universal set is the set of
Y_Kistochka [10]

Answer:

The set of numbers of the form \frac{p}{q} , q≠0 and q≠ 1 or -1.

Step-by-step explanation:

We have that,

U = the universal set = the set of all rational numbers

S = set of all integers.

It is required to find S^{c}.

Now, S^{c} is the complement of the set S.

i.e. S^{c} = U - S = set if rational numbers - set of integers

i.e. S^{c} = the set of rationals which are not integers i.e. the set of points of the form \frac{p}{q} , q≠0 and q≠ 1 or -1.

Alex

Answer:

  • 1. D
  • 2. C

Step-by-step explanation:

1. .....................................................................................................

A. This is a functional relationship as the number of workers depend on the number of job sites.

  • y = 5x

B. This is a functional relationship as the amount of money is dependent on the number of withdrawals

  • y = 2500 - 200x

C. This is a functional relationship as the number of vitamins depend on the number of monkeys

  • y = 3x

D. This is NOT a functional relationship as the output is a fixed value. The performance and scoring may repeat.

2. .....................................................................................................

<h3>Given</h3>
  • A = 62x -100
  • B = 2x - 3
<h3>To find </h3>
  • A/B
<h3>Solution</h3>
  • A/B =
  • (62x - 100)/(2x - 3) =
  • (31*2x - 31*3 - 7)/(2x - 3) =
  • (31(2x - 3) -7)/(2x - 3) =
  • 31 - 7/(2x - 3)

Correct option is C.

A gallon of paint covers 400 square feet. How many square feet will 2 3/8 gallons of paint cover?
Black_prince [1.1K]
1 gal = 400 ft²
2 3/8 gal = ? ft²

to solve, use similar ratios with units gal/ft² and compare

(1)/(400) = (2 3/8)/(x)

*multiply both sides by (x) and divide both sides by (1)/(400), you get:

x = (400)*(2 3/8)/(1) = 400*(2 3/8) = 400*2 + 400*3/8 = 800 + 150 = 950 ft²

<u><em>answer is 950 ft²</em></u>
