Answer: D) phone calls made on a landline

More and more people are using cellphones, because of the convenience of having your phone with you at all times. From an economical standpoint, it doesn't make sense to pay for both a cell phone and a landline (especially if your budget is thin). So many people have decided to drop having a landline all together. The less people using a landline produces a negative downward trend, which is why we have negative linear correlation.

The number in between 5 and 6 is 5.5.

The mass of the copper metal is 5.50 g.

Answer:

Approximately 18.0.

Step-by-step explanation:

To find x, we can use the Law of Cosines.

The Law of Cosines is the following:

[tex]c^2=a^2+b^2-2ab\cos(C)[/tex]

Now that the c is the side we're trying to find. Thus, the c is x. Also, Angle C is the angle opposite to c (or x). a and b are the two sides next to Angle C.

Plug in x for c, 16 for a, 30 for b, and 30 for Angle C:

[tex]x^2=(16)^2+(30)^2-2(16)(30)\cos(30)\\x^2=1156-960\cos(30)\\x=\sqrt{1156-960\cos(30)} \\x\approx18.0171[/tex]

Answer:

((-1, 2), (1, 3), (1, 5), (-3, 4))

Step-by-step explanation:

For a set of ordered pairs to be considered a function, a domain value should have exactly just 1 range value.

If a domain value is having more than 1 range value assigned to it, it is not a function. In order words, an x variable value should have exactly just one y variable value assigned to it.

x variables are domain values while y variables are the range values.

In the ordered pairs, ((-1, 2), (1, 3), (1, 5), (-3, 4)), the two pairs, (1, 3), (1, 5), have the same x variable value with different y-variable values assigned to each. This renders the set of ordered pairs not to be a function. Domain value 1, is having different range value of 3 and 5.

Answer:

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

∠ c  = 90° ( angle in a semicircle ), thus

d = 180° - (16 + 90)° = 180° - 106° = 74° ( angles in a Δ )

If one angle is 16° then the measure of angle d is 76°.

An angle is the figure formed by two rays called the sides of the angle, sharing a common point called the vertex of the angle.

We know that each angle of a rectangle and square is equal to 90°. When we observe the given figure then we can see that angles are formed in a rectangle and a,b,c,d,14 and 16 all are in rectangle, so in this way, 14°+d=90°.

d=90-14

d=76°

Hence if one angle is 16° then the measure of angle d is 76°.

Answer: Hi!

To make an expression that represents ten and a number being divided (hence, quotient) we will use the variable x for the unknown number:

10 ÷ x

You would use this expression to represent the quotient of 10 and a number.

Hope this helps!

The quotient of 10 and a number​ is equal to [tex]\frac{10}{n}[/tex].

In Mathematics, quotient simply means division i.e the division of a particular number by another number.

In this exercise, you will simply divide the value of 10 by n.

Therefore, translating the word sentence into an algebraic expression, we have;

Quotient of 10 and a number is:

Hi,  

a line is define by  the following equation :    y = ax+b

where  a  is the slope, and  b the value for x = 0

so you have :        a*3 +b = 3   for the first point

                              a*(-5) +b = 4  for second point  

  so you have a system :      3a+b =3

                                              -5a+b = 4

so :       3a+b -(-5a) -b = 3-4

             3a+5a +b-b = -1

             8a = -1

                a = -1/8

then a = -1/8   so , in remplacing a  by it's  value  in one equation ,   b  is :             3(-1/8) +b = 3

 -3/8 +b = 3

           b = 3 +3/8

           b =  24/8 +3/8

          b =  27/8

let's check :     3 (-1/8) + 27/8 =  -3/8 +27/8 = 24/8 = 3

first point is correct  

                         -5( -1/8) + 27/8 =  5/8 +27/8 =  32/8 = 4

second point is correct

Answer:

a) 16.82 mg

b) 24 days

Step-by-step explanation:

Formula for exponential growth is given as:

[tex]A=A_0b^{\frac{t}{c}}[/tex]

Where A is the final population

[tex]A_0[/tex] is the initial population

b is the growth factor

c is the time taken for the growth 'b'

t is the amount of time

Here, We are given the following:

[tex]A_0[/tex] = 5 mg

b = 2 (Given because it doubles)

c = 4 days

a) A = ?

Using the formula:

[tex]A=5 \times 2^{\frac{7}{4}}\\\Rightarrow A=5 \times 2^{1.75} \\\Rightarrow A = \bold{16.82\ mg}[/tex]

b) Given

A = 320 mg

t = ?

Using the above formula again:

[tex]320 = 5 \times 2^{\frac{t}{4}}\\\Rightarrow \dfrac{320} 5= 2^{\frac{t}{4}}\\\Rightarrow 2^{\frac{t}{4}} = 64\\\Rightarrow 2^{\frac{t}{4}} = 2^6\\\Rightarrow \dfrac{t}{4} = 6\\\Rightarrow t = 6 \times 4\\\Rightarrow \bold{t = 24\ days}[/tex]

So, the answers are:

a) 16.82 mg

b) 24 days

please mark it the brainliest!

Answer:

it would be a complete graph

Step-by-step explanation:

Let's assume that total employees are x .

Three - fifths of x is female employees .

→ Female employees = 3x/5 .

Then male employees will be :-

→ Male employees = x - 3x/5

So male employees are 2x/5 .

→ Employees under 18 = x/4

→ Female under 18 = one - third of total female employees.

→ Female under 18 = 3x/5 (1/3)

So Female employees under 18 are x/5 .

→ Now male under 18 = x/4 - x/5

Now male above 18 are = 2x/5- x/20

Ratio of Male above 18 : Male below 18

→ 7x/20 : x/20

→ 7 : 1

So the ratio is 7 : 1 .

Answer:

440m

Step-by-step explanation:

First you would square root the value 12100 to get one of the length of the square.

[tex]\sqrt{121000}[/tex]=110m

A square has four sides so,

110*4=440m

Answer:

440m

Step-by-step explanation:

Formula of a square's field : a square

So, area is 12,100. Then, let's take this value into the square root.

Now, we found the one edge of this square which is 110m

For finding perimeter, a square has a 4 edge. So, we multiple 110 x 4 = 440m.

Answer:

(12,-6)

Step-by-step explanation:

Answer:

(12,-6)

Step-by-step explanation:

When dilating points, you multiply both coordinates (x and y) by the scale factor.

The point we are given is: (4,-2) and the scale factor is 3.

Multiply each coordinate by the scale factor of 3.

X-coordinate: 4

     4* 3= 12

New X-coordinate: 12

Y-coordinate : -2

    -2 * 3= -6

New Y-coordinate: -6

Our new x-coordinate is 12 and y-coordinate is -6. Therefore, our point is (12,-6). So, the image of point (4,-2) after a dilation of 3 is (12, -6).

Answer:

The opposite of integer 4 units away from -6 is 10.

Step-by-step explanation:

We know that the opposite of the opposite of a number, say 2, is the number itself.

That is:

Opposite of 2 is -2.

Then the opposite of -2 is:

- (-2) = 2

Now consider a number line.

The number that is 4 units away from -6 is -10.

So, the number is -10.

The opposite of -10 will be:

- (-10) = 10

Thus, the opposite of integer 4 units away from -6 is 10.

AB can be calculated using the formula [tex] d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]

Answer:

5x^2+1

Step-by-step explanation:

2x^2 and 3x^2 are like terms so just add them which gives 5x^2.

2 and -1 are like terms so combine them to make 1.

Answer:

5x²-1

Step-by-step explanation:

We are given the expression:

[tex]2x^2+2 + 3x^2- 1[/tex]

and asked to simplify.

To simplify this expression, we must combine like terms.

2x²⇒ this has a variable, x²

2⇒ no variable

3x²⇒this has a variable, x²

-1⇒ no variable

Group the like terms.

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

Add 2x² and 3x². Add the coefficients and add an x² on the end.

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

[tex](5)x^2+(-1+2)[/tex]

[tex]5x^2+(-1+2)[/tex]

Combine -1 and 2.

[tex]5x^2+(-1)[/tex]

[tex]5x^2-1[/tex]

The expression 2x²+2+3x²-1 simplified is 5x²-1

Answer:

4 (c - 6)

Step-by-step explanation:

Simplify the following:

6 c - 2 c - 16 - 8

Hint: | Group like terms in 6 c - 2 c - 16 - 8.

Grouping like terms, 6 c - 2 c - 16 - 8 = (6 c - 2 c) + (-8 - 16):

(6 c - 2 c) + (-8 - 16)

Hint: | Combine like terms in 6 c - 2 c.

6 c - 2 c = 4 c:

4 c + (-8 - 16)

Hint: | Evaluate -8 - 16.

-8 - 16 = -24:

4 c + -24

Hint: | Factor out the greatest common divisor of the coefficients of 4 c - 24.

Factor 4 out of 4 c - 24:

We have to find how many legs should the chair have.

How to find balanced position of an object with respect to their mass?

We can find it after observing the center of mass which is a position defined in respect  to an object . It is the average position of all the particles of the system, placed according to their masses.

Now,

In order to make non rocked chair from side which has one leg of different length.
