Answer:

$5.40 for 12 letters

Step-by-step explanation:

you need to find the cost for 1 unit then multiply that by 12, so you take the cost (4.50) and divide it by letters (10) so you get 0.45. So that is the cost of q letter, then you that that unit rate and multi[ly it by the number that you need to figure out (12) so .45x12=5.40  

12 letters=$5.40

Answer:

The simplest radical form is [tex]9\sqrt{5}[/tex] ⇒ (c)

Step-by-step explanation:

To simplify any square root;

Examples:

1. Simplify [tex]\sqrt{8}[/tex]

factorize 8 using prime numbers

8 = 2 × 2 × 2, then [tex]\sqrt{8}=\sqrt{(2)(2)(2)}[/tex]

Take two of 2 out the root, then [tex]\sqrt{8}=2\sqrt{2}[/tex]

2. Simplify [tex]\sqrt{18}[/tex]

factorize 18 using prime numbers

18 = 2 × 3 × 3, then [tex]\sqrt{18}=\sqrt{(2)(3)(3)}[/tex]

Take the two 3 out the root, then [tex]\sqrt{18}=3\sqrt{2}[/tex]

Let us simplify [tex]3\sqrt{45}[/tex]

∵ 45 = 3 × 3 × 5

∴ [tex]3\sqrt{45}=3\sqrt{(3)(3)(5)}[/tex]

→ Take the two 3 out by one 3

∴  [tex]3\sqrt{45}=3(3)\sqrt{5}[/tex]

→ Multiply the numbers out the root

∴ [tex]3\sqrt{45}=9\sqrt{5}[/tex]

∴ The simplest radical form is [tex]9\sqrt{5}[/tex]

Answer:

314 large cups

Step-by-step explanation:

72x4.35=313.2

Answer:

The total amount of Large coffee cups sold should equal to 313.2

Step-by-step explanation:

4.35 x 72 = 313.2

The number of hours she must work in a month to pay for her car payment and gas is 22 hours

inequality is the relationship between two expressions that are not equal, employing a sign such as ≠ “not equal to,” > “greater than,” or < “less than.”.

For one month, Audrey has to pay $350 for her payment and $35 for gas, meaning that she will need to pay $385 per month.

$350 + $35 = $385

Audrey makes $17.50 an hour.  Set up equality to find the number of hours she must work to pay for her car payment and gas.

17.50x > 385

(17.50x)/17.50 > 385/17.50

x > 22

Therefore, Audrey must work at least 22 hours to pay for her car payment and gas.

Answer:

[tex]2[/tex]

Step-by-step explanation:

Order of Operations: BPEMDAS

Step 1: Write expression

[tex]\frac{12/2(3)}{3(3)}[/tex]

Step 2: Evaluate

The value of n that makes the equation [tex](13 + 4i) + n = 0[/tex] true is (d) -13 - 4i.

The equation is given as:

[tex](13 + 4i) + n = 0[/tex]

Remove brackets

[tex]13 + 4i + n = 0[/tex]

Subtract 13 from both sides

[tex]13 - 13 + 4i + n = 0 - 13[/tex]

Evaluate like terms

[tex]4i + n = - 13[/tex]

Subtract 4i from both sides

[tex]4i -4i + n = - 13 -4i[/tex]

Evaluate like terms

[tex]n = - 13 -4i[/tex]

The equation cannot be further simplified.

Hence, the value of n is (d) -13 - 4i

The algebraic expression to model that "the product of a number and fifteen" is 15x, where x represents the unknown number. The statements A, C, and D are true.

Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers.

The algebraic expression to model the unknown number problem "the product of a number and fifteen" is 15x, where x represents the unknown number.

From the given options, the following statements are true:

A. You can replace ‘a number’ with a variable to represent an unknown value.

C. Product means the result of multiplying two numbers.

D. The coefficient is 15.

B. is false because the product means the result of multiplying two numbers, not adding them.

E. is not necessarily true for all cases. The product of a number and a variable can be represented in different ways depending on the context and convention, such as using a dot or parentheses.

Answer:

Because both lines intersect at one given point, this means that wherever they intersect both lines will have the same length on each side because that one point serves as the half way point between the intersection. meaning that if two lines cross and it creates the vertical angle of 150⁰ then by definition the side that is across that intersection point will also be 150⁰

Answer:

Step-by-step explanation:

If two lines i.e. AB & CD intersect each other. They have two pair of opp. angles.

i.e.

∠AOC,∠DOB,∠AOB,∠COB.

To prove :- ∠AOC=∠DOB & ∠AOD=∠COB

Proof :-

∠AOC+∠AOD=180 °

  [linear pair] ___(1)

∠AOD+∠BOD=180°  

   [linear pair] ___(2)

from eq. (1) & (2)

∠AOC+∠AOD=∠AOD+∠BOD

i.e.  [∠AOC=∠BOD]

Similarly [∠AOD=∠COB]

Hence proved.

Answer:

option 1

option 3

option 4

Step-by-step explanation:

Inversely proportional means "one quality increases, the other decreases " or "one quantity decreases ,other increases. " Inverse relantionship, that's it.

option 1:

Since the volume is given as 56 and we know the volume is area of base * height, to keep the volume at constant [56], if height increases, area of base would need to decrease, and vice versa. So Inversely proportional.

option 2:

The time spend in plowing a field with a tractor with increase when we area using more fuel.So more fuel used means more time spent. So these are directly proportional, Not inverse.

option 3:

Since the price is a constant, the amount of length we buy more,the price per one yard HAS to decrease, and vice versa. So ,this is Inverse relantionship.

option 4:

If the number of identical tractors. increase, it will take less time to plow the set 358 acre farm. And vice versa. So this is Inversely proportional as well.

Answer:

x = -5/4

Step-by-step explanation:

3x= 5+7x    (subtract 7x from both sides)

3x - 7x = 5

-4x = 5    (divide both sides by -4)

x = 5/(-4)

x = -5/4

Using inverse function concepts, the correct option is:

B. Domain: x < -2 Range: y> 3

--------------------------

A similar problem is given at https://brainly.com/question/24603090

The correct option is Option C: The function shown on the graph has a greater rate of change and a higher starting point.

The rate of change of function is the change in the value of the function with respect to x value.

rate of change of function f(x)= df(x)/dx= f'(x)

Here the function given in the question is y=2x-5

rate of change of function= f'(x)= df(x)/dx= dy/dx= d(2x-5)/dx= 2

the starting point of the function f is y-intercept of the function.

the y-intercept of the function is the point where the function touches the y-axis which can be calculated by putting x value is equals to 0.

y= 2x-5

⇒y= 2*0-5

⇒y= -5

The starting point of function is -5.

Given the graph has slope = |y-intercept| / |x intercept|

= 4/1 =4

rate of change of graph = slope of graph= 4

similarly, the y-intercept of the function is the point where the function touches the y-axis which can be calculated by putting x value is equals to 0.

The y-intercept of the graph= the starting point of the graph= -5

Therefore the function in the graph has a higher rate of change as well as a higher starting point.

From the above, it is clear that the correct option is Option C: The function shown on the graph has a greater rate of change and a higher starting point.
