Answer:

Domain is; d is a set of non - zero integers.

Range will be p(d) for values of; d > 0 or d < 0

Step-by-step explanation:

In Mathematics, the domain is the set of all input values in a given function while range is the set of output values for each given input function.

Thus, looking at the function given;

p(d) = -(28.2/d) + 0.859

It is clear that if d = 0, we will have an undefined solution as any number divided by zero is undefined.

Thus, the domain is; d is a set of non - zero integers.

Range will be p(d) for values of; 0 < d < 0

Answer:

Step-by-step explanation:

10). AD = BC [If ABCD is a parallelogram]

     3x + 1 = 6x - 4

     6x - 3x = 1 + 4

     3x = 5

     x = [tex]\frac{5}{3}[/tex]

11). If ABCD is a parallelogram,

     AB = CD

     5x - 8 = 2x + 7

     5x - 2x = 7 + 8

     3x = 15

     x = 5

12). If ABCD is a parallelogram,

     AB = CD

     AB║CD and BD is a transversal intersecting these parallel lines.

     ∠ABD ≅ ∠BDC [Alternate interior angles]

     4x - 1 = x + 38

     4x - x = 38 + 1

     3x = 39

     x = 13

Answer:

n=4

Step-by-step explanation:

7n - 4 = 24

24 + 4 = 28

7n = 28

n = 4    

OR  plug in the sets you gave and see if they equal 24

Answer:

slope or m= -5/2

Step-by-step explanation:

Answer:

x = 8

Step-by-step explanation:

You know that 7x - 4 and 5x + 12 are equal, so you can set up an equation and solve it:

[tex]7x - 5 = 5x + 12[/tex]

subtract 5x from both sides

[tex]2x-4=12[/tex]

Add 4 to both sides

[tex]2x = 16[/tex]

divide both sides by 2

[tex]x = 8[/tex]

Answer:

7x - 4......1

5х + 12......2

on multiplying by 3 in eq 1

= 21x-12...3

on substracting eq 2 from 3

21x-12=0

-5x+12=0

=16x=0

x=1/16

Answer:  $ 17.72

Step-by-step explanation:

Cost of soda = $2.15 , Cost of chicken = $8.77 , Cost of slice of cake = $4.10.

Total bill amount = (Cost of soda ) + (Cost of chicken) +(Cost of slice of cake)

= $ (2.15 + 8.77 +4.10)

= $ 15.02

Tip amount = 18% of Total bill amount

= 0.18 (15.02)

= $ 2.7036 ≈  $2.70

Entire bill = Total bill amount  + Tip amount

= $ ( 15.02+2.70)

= $ 17.72

Hence, entire bill = $ 17.72

Answer:

Option B.

Hey there!

According to the question,

45 miles per hour is given.

Then;

1 mile = 1.60 km

45 miles = 1.60*45

= 72 km.

Therefore, 45miles is equal to 72 km.

Answer:

64

Step-by-step explanation:

[tex](6+1/3x)^2[/tex]

Lets first substitute x into the equation:

[tex](6+1/3[6])^2[/tex]

1/3 times 6 = 2

[tex](6+2)^{2}[/tex]

[tex]8^{2}[/tex]

Which equals 64

Answer:

The distance covered by a train in 1 minute = 1.25 kilometers

The distance covered by a train in 100 minutes = 125 kilometers

Step-by-step explanation:

The distance covered = 7.5 kilometers

Time taken = 6 minutes

Calculating unit rate

unit rate = 7.5 kilometers / 6 minutes

              = 1.25 kilometers per minute

Thus,

The distance covered by a train in 1 minute = 1.25 kilometers

and

The distance covered by a train in 100 minutes = 1.25 × 100

                                                                                = 125 kilometers

Answer: 1/15

Step-by-step explanation:

The number of striped socks is 2 while the number of total socks are 6. If he chooses a striped socks at first, that will be 2/6.

If he chooses it the second time, the probability will be 1/5 since there'll be 5 socks left and 1 striped.

The probability that Derek selected a striped sock both times will be:

= 2/6 × 1/5.

= 2/30

= 1/15

Answer:

BEC°

Step-by-step explanation:

complementary means "to add up to 90°"

90° - 34° = 56°

the Z confused me for a bit, then figured out you tried to type in the angle sign.

Answer:

A. 35°C.

Step-by-step explanation:

35 C (Celsius), converted to F (Fahrenheit), would be 95. Which would make it a hot day.

Answer:

32 chickens

Step-by-step explanation:

Let

The number of cows = x

The number of chickens = y

A farm raises cows and chickens. The farmer has a total of 46 animals.

x + y= 46..... Equation 1

x = 46 - y

Number of legs of chickens = 2

Number of legs of cows = 4

One day he counts the legs of all his animals and realizes he has a total of 156 legs.

Hence:

2x + 4y = 156.... Equation 2

We substitute 46 - y for x in Equation 2

2(46 - y) + 4y = 156

92 - 2y + 4y = 156

- 2y + 4y = 156 - 92

2y = 64

y = 64/2

y = 32

Solving for x

x = 46 - y

x = 46 - 32

x = 14

The number of cows = x = 14 cows

The number of chickens = y = 32 chickens

Therefore, the number of chickens that the farmer has is 32 chickens

10??? sorrybi have no idea

Answer: 219 children and 72 adults swam at the public pool that day.

Step-by-step explanation:

Let x = Number of children , y= Number of adults.

As per given,  x+y = 291      (i)

1.5x+2y = 472.50         (ii)

Multiply 2 on both sides of (i) , we get

2x+2y = 582  (iii)

Eliminate (ii) from (iii), we get

0.5x = 109.5

[tex]\Rightarrow x=\dfrac{109.50}{0.5}=219[/tex]

Put value of x= 219 in (i)

219+y= 291

⇒ y = 291-219 = 72

Hence, 219 children and 72 adults swam at the public pool that day.

Answer:

22.5

Step-by-step explanation:

You subtract 3 from both sides and then divide 2 from both sides which should look like this

3(2x)=48

-3      -3

2x=45

-:- 2

x=22.5
