Answer:

Gloria would text 360 words if Erica texted 500 words.

Step-by-step explanation:

Let 'y' be the number of words Gloria texts

Let 'x' be the number of words Erica texts

Given that the relationship is  proportional

y ∝ x

y = kx

where 'k' is called the constant of proportionality

Given

substituting the values to determine the constant of proportionality 'k'

k = y / x

   = 18 / 25

Thus, the constant of proportionality = k = 18/25

When Erica texted 500 words, we need to determine the number of words Gloria will text.

so

k = 500

y = ?

k = y / x

y = kx

  = 18 / 25 × 500

  = 360 words

Thus, Gloria would text 360 words if Erica texted 500 words.

The expression of the mathematical statement given as the difference between 12 and ten times a number is 28 is 12 - 10x = 28

The mathematical statement is given as

The difference between 12 and ten times a number is 28

The difference of numbers means subtraction

So, we have

The difference between 12 and ten times a number is 28 => 12 - ten times a number is 28

Let the number be x

So, we have

The difference between 12 and ten times a number is 28 => 12 - ten times x is 28

The product of numbers means multiplication

So, we have

The difference between 12 and ten times a number is 28 => 12 - 10 * x is 28

Evaluate the product

The difference between 12 and ten times a number is 28 => 12 - 10x is 28

Rewrite as

The difference between 12 and ten times a number is 28 => 12 - 10x = 28

Hence, the expression of the mathematical statement given as the difference between 12 and ten times a number is 28 is 12 - 10x = 28

These are the characteristics of the exponential growth and exponential decay functions

Properties of Exponential Growth Functions

The function is an increasing function; y will increase as x will increase. Range: If a>0, the range is {positive real numbers} The graph is continually above the x axis. Horizontal Asymptote: when b>1, the horizontal asymptote is the negative x axis, as x will become huge negative.

Properties of Exponential Decay Functions

Answer:

34.8 N at 2.5 degrees from the positive x-axis

Step-by-step explanation:

From the given information:

The force F makes an angle A with the positive x axis can be expressed in terms horizontal and vertical components.

[tex]F_x = F cos A\\\\ F_y = Fsin A[/tex]

Given that

[tex]F_1 = 50 \ N[/tex]

[tex]\theta_1 = 30 ^0 \ \ \ (x-axis)[/tex]

[tex]F_{1x} = F_1 \times Cos A_1[/tex]

=  50 × cos 30

= 43.3 N

[tex]F_{1y} = F_1 \times Sin \ A_1[/tex]

= 50 × sin 30

= 25 N

Similarly;

[tex]F_2 = 25 \ N[/tex]

[tex]\theta_2 = 250 ^0 \ \ \ ( x-axis)[/tex]

[tex]F_{2x} = F_2 \times cos \ A_2[/tex]

= 25 × cos 250

= - 8.55 N

[tex]F_{2y} = F_2 \times A_2[/tex]

= 25 × sin 250

= -23.5 N

The total net force;

[tex]F_{net} = F_{(net)}_x + F_{(net)}_y[/tex]

[tex]F_{net} = (F_{1x} + F_{2x} ) i + (F_{1y} + F_{2y} )j[/tex]

[tex]F_{net} = (43.3 - 8.55) i + (25-23.5 ) j[/tex]

[tex]F_{net} =34.75 i + 1.5 j[/tex]

[tex]|F_{net} | = \sqrt{F_{net}_x^2 + F_{net}_y^2}[/tex]

[tex]|F_{net} | = \sqrt{34.75^2 + 1.5^2}[/tex]

[tex]|F_{net} | = 34.8 \ N[/tex]

Finally, the direction of the angle for the net force is:

[tex]tan \theta = \dfrac{F_{net_y}}{F_{net_x}}[/tex]

[tex]\theta = tan^{-1} \Big (\dfrac{F_{net_y}}{F_{net_x}} \Big)[/tex]

[tex]\theta = tan^{-1} \Big (\dfrac{1.5}{34.75}} \Big)[/tex]

[tex]\theta = tan^{-1}( 0.043165)[/tex]

[tex]\theta \simeq 2.5^0\ with \ positive \ x-axis[/tex]

Answer:

  330 seconds (5 minutes, 30 seconds)

Step-by-step explanation:

You want the time required for a 5×11 enlargement when a 2×3 enlargement takes 36 seconds, and time is proportional to area.

The area of a rectangle is the product of length and width.

  area of smaller enlargement: 2×3 = 6

  area of larger enlargement: 5×11 = 55

The time is proportional to the area, so when the area increases by a factor of 55/6, so does the time:

  (36 seconds) × (55/6) = 330 seconds

The time required for a 5×11 enlargement is 330 seconds.

Given:

Two points that are close to the line of best fit are (2,70) and (4.5, 90).

To find:

Th equation of best fit line using the given two points.

Solution:

We know that, if a line passes through the two points, then the equation of line is

[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]

Two points (2,70) and (4.5, 90) are close to the best fit line.

Consider the two points (2,70) and (4.5, 90). So, the equation of line is

[tex]y-70=\dfrac{90-70}{4.5-2}(x-2)[/tex]

[tex]y-70=\dfrac{20}{2.5}(x-2)[/tex]

[tex]y-70=8(x-2)[/tex]

[tex]y-70=8x-16[/tex]

Adding 70 on both sides, we get

[tex]y=8x-16+70[/tex]

[tex]y=8x+54[/tex]

Therefore, the equation of best fit line is [tex]y=8x+54[/tex].

Answer:

David gets £34, Egil gets £119 and Frances gets £153.

Step-by-step explanation:

Let the amount of money David gets be 2x, Egil be 7x and Frances be 9x.

7x = 2x + 85

7x - 2x = 85

5x = 85

x = 85 ÷ 5

x = 17

David (2x) = 2 × £17

                 = £34

Egil (7x) = 7 × £17

             = £119

Frances (9x) = 9 × £17

                     = £153

Step-by-step explanation:

coz the expression one must devide (8x)2 to get 4x and to find the area one must multiplely 4x*4 to get 16

The solution is Option D.

The expression ( 8x )² represents the area of a square with side length 8x

What is the area of a square?

A square is a 4 sided polygon where all the sides are of equal length.

The area of the square is the square of any one of its side

Let a be the side of the square

Area of the square = a²

Given data ,

Let a be the side of the square

Area of the square = a²

Let the expression be A

Now , the value of A is given by

The value of A = s²

where s is the side length of the square

Now , let the expression be B

where the value of B is given as

The value of B = ( 8x )²

Now , 8x will be the side length of the square with ( 8x )² as its area

Therefore , the side length of the square is 8x

Hence , The expression ( 8x )² represents the area of a square with side length 8x

Answer:

[tex]Sales\ Price = \$57.12[/tex]

Step-by-step explanation:

Given

[tex]Price = \$84.00[/tex]

[tex]Markdown = 32\%[/tex]

Required

Determine the sales price

First, we calculate the markdown price.

This is calculated by multiplying the original price the markdown percentage

[tex]Markdown\ Price = \$84.00 * 32\%[/tex]

Convert % to decimal

[tex]Markdown\ Price = \$84.00 * 0.32[/tex]

[tex]Markdown Price = \$26.88[/tex]

The sales price is then calculated as:

[tex]Sales\ Price = \$84.00 - \$26.88[/tex]

[tex]Sales\ Price = \$57.12[/tex]

Hence, the sales price after markdown is $57.12

The probability that perhaps the stock returns will be less than 18.5% is 0.542.

In most cases where the possible study population is large, a normal distribution is chosen. Apart from its easier application than that of other distribution methods, this is the primary reason for its efficiency.

Let X be the annual return on common stocks throughout 1926 to 1992.

The average of X is 16.5%.

X has a standard deviation of 19%.

Assume X is regularly distributed.

X∼N(μ,σ)

∼N(16.5,19)

The likelihood that stock returns seem to be less than 18.5% is calculated using the Z-table, as shown below.

P(X < 18.5) = [tex]P\left(\frac{X-\mu}{\sigma} < \frac{18.5-16.5}{19}\right)[/tex]

                  = P(Z < 0.1053)

                   = 0.542

The probability that perhaps the stock returns will be less than 18.5% is 0.542.

Answer:

The tree's height is 142.24 cm.

Step-by-step explanation:

There are 12 inches in a foot. This means that 4 feet equal 4 * 12 = 48 inches. Since there are 8 more inches, you add 8 to 48. The sum is 56. There are 56 inches in 4 feet and 8 inches.

Now, to convert:

56 * 2.54 = 142.24 (inches to centimeters)

The tree's height is 142.24 cm.
