Answer:

I think they are all always.

Step-by-step explanation:

They are called rational because they are the ratio, or quotient, of two integers

numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.

If a square root is not a perfect square, then it is considered an irrational number. These numbers cannot be written as a fraction because the decimal does not end and does not repeat a pattern.

Answer:

C= 5/9 * (F -32)

Move 5/9 to the left which makes it 9/5

9/5 * C = (F -32)

Move the -32 to the left

9/5 * C +32 = F  or to make it read left to right

Fahrenheit  = 9/5 * Celsius + 32

The value of m in the inequality 28 > 4+1.5m is 16

A relationship between two expressions or values that are not equal to each other is called 'inequality.

To solve for m, we need to isolate it on one side of the inequality.

We can start by subtracting 4 from both sides:

28 - 4 > 1.5m

Simplifying:

24 > 1.5m

Next, we can divide both sides by 1.5:

16 > m

So Kate can travel at most 16 miles in the cab if she wants to spend no more than $28 on cab fare.

Therefore, the value of m in the inequality 28 > 4+1.5m is 16

Answer: D

Step-by-step explanation: D because if your turn 1/2 into a decimal point it 0.5 (don't forgot to add the negative) and so i then divided -0.5 from x and just got x then you have to do the same for the other side. So i took 4 and divided it by -0.5 and got -8 to the expression would be x is greater then or equal to -8. you plot the dot at -8 and the line goes in front of it because it is lesser or equal to x (remember you reverse the problem if you say it back words so don't get confused), but after my long explanation just pick D

Step-by-step explanation:

= 40 + [ 3 { 18 ÷ ( 9 - 3 ) - 11 - 9 } + 4 ]

= 40 + [ 3 { 18 ÷ 6 - 11 - 9 } + 4

= 40 + [ 3 { 3 - 20 } + 4

= 40 + [ 3 {- 17 } + 4

= 40 + ( - 51 ) + 4

= 40 + 4 - 51

Answer:

Option D: the x-intercept represents the minimum amount of photographs he must sell to pay for his photography lab.

Step-by-step explanation:

We are told that his monthly profit is given by the relation;

P = 32.5x - 845

Where x is number of pictures he needs.

We want to find what the x - intercept represents.

x intercept means that the y-value at that point is zero.

Thus, x-intercept means the profit is 0.

If profit is zero, it means his cost of operating his photography lab each month is equal to the amount of photographs he is able to sell.

Thus, it means that the x-intercept represents the minimum amount of photographs he must sell to pay for his photography lab monthly.

Option C. 3/4.

the slope is 3/4 for any two adjacent points.

Then use the point-slope formula y-y1=m(x-x1) where m slope and (x1, y1) point

y-1=(3/4)(x-11)

y=(3/4)x-(29/4), distributing and moving the 1 over.

A linear function is a function of the form f(x) = ax + b, where a and b are real numbers. Here, a represents the gradient of the line, and b represents the y-axis intercept (which is sometimes called the vertical intercept).

Answer:

The value of x is 27

Step-by-step explanation:

The sum of the exterior angles of the n-side polygon is 360°

Let us use this rule to solve the question

∵ The given polygon has 4 sides

∴ It has 4 exterior angles, one on each vertex

→ By using the rule above

∴ The sum of the 4 angles is 360°

∵ The exterior angles are (2x + 40)°, (4x)°, (x + 50)°, and (3x)°

→ Add them, then equate the sum by 360

∴ (2x + 40) + (4x) + (x + 50) + 3x = 360

→ Add the like terms in the left side

∵ (2x + 4x + x + 3x) + (40 + 50) = 360

∴ 10x + 90 = 360

→ Subtract 90 from both sides

∵ 10x + 90 - 90 = 360 - 90

∴ 10x = 270

→ Divide both sides by 10

∴ x = 27

∴ The value of x is 27

im sorry if this is wrong but im 99% sure this is right

i only put things in parenthesis to make things work better in my brain

Answer:

m = -2

Step-by-step explanation:

4 + 4{m + 1} = 0           {Subtract 4 form both sides}

   4{m + 1} = -4

   4m + 4 = -4             {Subtract 4 form both sides}  

         4m = -4 - 4

        4m  = -8             {Divide both sides by 4}

        m = -8/4

m = -2

The number of weeks that they cat treats will train out is 27 weeks.

From the information given, the total grams will be:

= 200 + (2.5 × 1000)

= 200 + 2500

= 2700 grams.

Then he uses about 100 grams of cat treats every week, the number of weeks will be:

= 2700 / 100

= 27

The largest value of x that would make buying the individual card less expensive than buying the package is 57.

The total cost of buying the individual thankyou cards is the product of the cost of buying one card and the number of cards bought.

Total cost of buying the individual thankyou cards = cost per card x number of cards bought

$0.15 × x = $01.5x

The inequality equation that would be used to represent this question is

(total cost of individual thankyou cards) > cost of the package

$0.15x > $8.50

In order to determine the value of x, divide both sides of the equation by 0.15

x > (8.50 / 0.15)

x > 56.67

x > 57 to the nearest whole number
