Answer: (1) d, f (2) c, d, f (3) e, f (4) a, b, c, d, f (5) e, f

Step-by-step explanation:

a) Natural Numbers: 1, 2, 3, ...

b) Whole Numbers: 0, 1, 2, 3, ... (add zero to the Natural numbers)

c) Integers: ..., -3, -2, -1, 0, 1, 2, 3, ... (add negatives to the Whole numbers)

d) Rationals: Add terminating and repeating decimals to Integers.

************

e) Irrationals: Non-repeating decimals that are non-terminating. This is its own category so cannot be a Rational number or above.

f) Real Numbers: ALL of the above (a - e) are Real numbers.

1) -5.2 has a terminating decimal so it is a RATIONAL number.

2) -4 is below zero so is an INTEGER which means it is also a RATIONAL #

3) -4.3212... is a non-terminating decimal so it is an IRRATIONAL number

4) $\sqrt4$ = 2 is a NATURAL number which means it is also a WHOLE number, INTEGER, and RATIONAL number.

5) $\sqrt7$ is a non-terminating decimal so it is an IRRATIONAL number

Maria took home a net pay of $1,200 on her paycheck this week. She worked 60 hours during this specific pay period and had deduc

erastovalidia [21]

Answer:

$25 per hour

Step-by-step explanation:

Net pay= $1200

Deductions= $300

Hours worked= 60

Total pay=$1200+ $300= $1500.

Since her net pay is the money left after deductions, so we add the netpay and deductions to get her total pay.

Therefore, to find her hourly pay, we simply divide the total pay by the hours worked,so we have 1500/60= $25/hour

Let the sandwich be represented by = x

Let the drink be represented by = y

As given, Joe charges $10.00 for two sandwiches and one drink, so equation becomes 2x+y=10 ....(i)

He charges $6.50 for one sandwich and one drink, so equation becomes x+y=6.50 ....(ii)

Subtracting (ii) from (i) we get

x=3.50

And as x+y=6.50

y=6.50-3.50=3.00

Hence, cost of a sandwich is $3.50 and a drink is $3.00

the question is incomplete. coordinates are missing

Let x represent the number of performances

cost = 8000+300x

revenue = 700x

To break even, the cost must be equal to the revenue.

$8000+300x=700x$

$400x=8000$

so x=20

Hence, 20 performances are needed to break even.

Let us take x for 20% material, y for 50% material

$\frac{20x+50y}{200}=30$

$20x+50y=6000$ ......... (1)

Accounting for volumes to use, x+y=200 or x=200-y ................ (2)

Putting the value of x in (1)

$20(200-y)+50y=6000$

$4000-20y+50y=6000$

$4000+30y=6000$

$30y=2000$

y=66.67

x=200-y = 200-66.67 =133.33

Hence, 133.33 ml of 20% acetic acid and 66.67% of 50% acetic acid is needed.
