Answer:  $27.35  

Step-by-step explanation:

First let's  find the variables.We will use x to represent the number of subscription sold and y we will represent the amount of money you will get paid.

So we know that , if you sell One You will get $1.25  so we could represent it by the point  (1,1.25) .

Now the second statement says that if you sell an additional subscription you will get an additional 15 cents or $0.15.Which means if you sell the second subscription, you will get  $1.40  because it is an additional 15 cents. We can also represent that by the point (2,1.40)  

Now using the two points come up with an equation.  

(1,1.25)

(2,1.40)    Find the slope and y intercept.

TO find the slope find the difference between y and divide it by the difference in x.

1.25 - 1.40 = 0.15

1 - 2  =   1  

0.15/ 1 =  0.15  So the slope is 0.15

Now use the point to find the y intercept. using the y-intercept formula,  

y = mx + b  

1.25 = 0.15(1) + b

1.25 =  0.15 + b

-0.15     0.15

 b = 1.1  

We can now write the equation  y = 0.15x + 1.1 to represent the whole situation where  x is still the number of subscriptions sold and y is the money you will get paid. Now to find how much you will earn for 175 subscriptions, you will input 175 for x and solve for y.

y = 0.15(175) + 1.1

y = 26.25 + 1.1

 y = 27.35

So you will earn $27.35  for 175 subscriptions

Answer: The answer is 8.5

Step-by-step explanation:

The value of the number expression 56.1 ÷ 6.6 is 8.5 after using the concept of arithmetic operation the answer is 8.5.

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.

It is given that:

56.1 divided by 6.6 (ones)

As we know from the arithmetic operation, the operation in which we do

the addition of numbers, subtraction, multiplication, and division.

= 56.1 ÷ 6.6

= 8.5

A number is a mathematical entity that can be used to count, measure, or name things. For example, 1, 2, 56, etc. are the numbers.

Thus, the value of the number expression 56.1 ÷ 6.6 is 8.5 after using the concept of arithmetic operation the answer is 8.5.

Step-by-step explanation:

Answer:

[tex]m=158[/tex]

Step-by-step explanation:

Angles on a straight line add up to 180 degrees.

Hence,

[tex](m-29)+51=180[/tex]

Remove brackets:

[tex]m-29+51=180[/tex]

[tex]m+22=180[/tex]

Subtract 22 from both sides:

[tex]m+22-22=180-22[/tex]

[tex]m=158[/tex]

Answer:

[tex]\displaystyle 158 = m[/tex]

Step-by-step explanation:

Both angles form a linear pair, making them supplementary angles. This means you set both expressions equivalent to one hundred eighty degrees:

[tex]\displaystyle 180° = 51° + [m - 29]° \hookrightarrow 180° = [m + 22]° \\ \\ \boxed{158 = m}[/tex]

The question is incomplete:

The telephone company offers two billing plans for local calls. Plan 1 charges ​$38 per month for unlimited calls and Plan 2 charges ​$18 per month plus ​$0.04 per call.

Use an inequality to find the number of monthly calls for which plan 1 is more economical than plan 2.

Answer:

Plan 1 is more economical than plan 2 when you make more than 500 monthly calls.

Step-by-step explanation:

Plan 1 costs $38 per month for unlimited calls and plan 2 costs $18 per month plus ​$0.04 per call which is: 18+0.04x and you can infer that plan 1 would be cheaper when you have to pay more than $38 using plan 2 and you can express it with the inequality:

18+0.04x>38, where x is the amount of monthly calls

Now, you can solve for x:

0.04x>20

x>20/0.04

x>500

According to this, plan 1 is more economical than plan 2 when you make more than 500 monthly calls.

(+6) + (-5) = 6 - 5 = 1  (P)

(+6) + (-9) = 6 - 9 = -3 (N)

(-6) + (-4) = -6 - 4 = -10 (N)

(+6) + (-2) = 6 - 2 = 4 (P)

(-7) + (+1) + (+2) = -7 + 1 + 2 = -4

(-2) + (-4) + (+3) = -2 - 4 + 3 = -3

(+5) + (+3) + (-1) + (-4) = 5 + 3 - 1 - 4 = 3

(-4) + (+3) + (-2) + (-6) = -4 + 3 -2 - 6 = -9

Answer:

Step-by-step explanation:

x    - an integer  then  2x + 1 is an odd number  (the smallest one)

consecutive odd numbers increase by 2

so the next odd number (the middle number) is:

2x + 1 + 2 = 2x + 3

and the third (the largest) consecutive is:

2x + 3 + 2 = 2x + 5

the sum of the the two largest numbers is:

2x + 3 + 2x + 5

3 times the smallest number is:  

3(2x + 1)  

the sum of the two largest is seven less than three times the smallest, so:

2x + 3 + 2x + 5 = 3(2x + 1) - 7

4x + 8 = 6x + 3 - 7

   -6x       -6x

-2x + 8 = -4

   -8       -8

-2x  = -12

÷(-2)    ÷(-2)

  x = 6

2x+1 = 2•6+1 = 13

2x+3 = 2•6+3 = 15

2x+5 = 2•6+5 = 17

Check:

2x+3+2x+5 = 15+3+15+5 = 38

38+7 = 45

45÷3 = 15

Answer:

cube root of -215 or -5.9

Step-by-step explanation:

Since this can't be a perfect cube the answer would be cube root of -215 or you find the closest perfect cubes which would be -5 and -6

-5cubed is -125 and -6cubed is -216  and -215 is closer to -216 the number approximately would be -5.9

Hope this helps :)

The cube root of the number -215 will be 5.99i.

An integer y such that y³ = x is known as the cube root of a number x in mathematics. All nonzero complex numbers have three different complex cube roots, while all nonzero real numbers have exactly one real cube root and two complex conjugate cube roots.

Iota is a fictitious unit number represented by the letter I and its value is -1. You may have encountered circumstances where the discriminant is negative while attempting to solve quadratic equations.

Given the expression of cube root is x³ = -215.

x³ = -215

x = ∛-215

x = 5.99i

Therefore, the cube root of the number -215 will be 5.99i.

Answer:

A. 10 bricks

B. 4 pounds

Step-by-step explanation:

Water = 39 pounds

brick dust = 48 pounds

Total mixture = water + brick dust

= 39 + 48

= 87 pounds

She spills 13 pounds of the mixture while stirring

Remaining mixture = Total mixture - Spillage

= 87 pounds - 13 pounds

= 74 pounds

The mixture is then poured into small dirt holes to make bricks. Each brick requires 7 pounds of mixture

Number of bricks made = Remaining mixture / pounds per brick

= 74 pounds / 7 pounds

= 10 bricks remaining 4 pounds of the mixture

A. What is the greatest number of bricks Lynn can make?

Answer:

the width of the path is 2.81 m

Step-by-step explanation:

given:

A circular plot of diameter 28m is surrounded by a path of uniform width

If the area of the path is 346.5^2

find:

the width of the path.

​---------------------------------

dia of circle = 28m

let Si = side of inner square path = 28 m

let So = outer side of square path = ?

1st step

is to get the total area

At = area of path + area of inner square

At = 346.5 + (28 x 28)

At = 1130 m²

2nd step

get the outer side of square path So

At = So²

1130 = So²

So = √1130

So = 33.62 m

lastly solve the width of path:

Width (w) = (So - Si)/2

w = (33.62 m - 28 m) / 2

w = 2.81 m

therefore,

the width of the path is 2.81 m
