Answer:

(C) j/j+80 and 36/k+36

Step-by-step explanation:

From the table attached :

Total Email (positive + negative) = j + 80

Number of positive Emails = j

Fraction of positive emails = (number of positive  / total number of emails) = j / (j + 80)

Total phone calls  (positive + negative) = 36 + k

Number of positive Emails = 36

Fraction of positive emails = (number of positive  / total number of emails) = 36 / (k + 36)

Answer:

[tex]0.4 * 0.8 = 0.32[/tex]

Step-by-step explanation:

Given

See attachment for model

Required

The equation of the model

Let the vertical and the horizontal shades be represented as x and y

On the vertical axis, 40 boxes are shaded.

So;

[tex]x = \frac{40}{100}[/tex]

On the horizontal axis, 80 boxes are shaded.

So;

[tex]y = \frac{80}{100}[/tex]

So, the equation is:

[tex]x * y[/tex]

This gives:

[tex]\frac{40}{100} * \frac{80}{100}[/tex]

Express as decimal

[tex]0.4 * 0.8[/tex]

Solve:

[tex]0.4 * 0.8 = 0.32[/tex]

Hence, the equation is:

[tex]0.4 * 0.8 = 0.32[/tex]

Answer:

x = 51

Step-by-step explanation:

The sum of internal angles for this rectangle is 360

x + 81 + 124 + 104 = 360 add like terms

x + 309 = 360 subtract 309 from both sides

x = 51

Answer:

1000 x .15 = 150 The car will lose 15% value after the first year which is $150. Subtract 150 from 1000 and the new value would be $850.

5020 x .15 = 753 This car lost 15% after the first year which is $753. Subtract 753 from 5020 and the new value would be $4287.

We observe this is a GP with the first term of 3 and common ratio of 5.

Equation for the nth term is:

Correct choice is D

Answer: x^4

Step-by-step explanation:

1. Rewrite the expression in fraction form:

(3√x²)^6 = x^(2/3)^6

2 is the exponent, so when written in fraction form, it is the numerator. 3 is the index or root, so in fraction form it is the denominator.

2. Solve:

x^(2/3)^6 = x^(12/3) = x^4

Because the exponent 2/3 is raised to the power of 6, you can use the power rule, which basically just means that whenever an exponent is raised to an exponent, multiply them. So, 2/3 * 6 equals 12/3, and 12/3 equals 4, making your answer x^4.

Answer:

can you show us the table?

Step-by-step explanation:

Answer:

2 grams

Step-by-step explanation:

One can see that the given diagram is that of a balancing scale, meanig that both sides are equal to each other. Therefore,  if one calls the weight of the triangle (t), then one can form an equation. Keep in mind that it is given that the square weighs (4) grams, and therefore, the square doesn't need a variable representation.

t + 4 + 4 = t + t + t + 4

Simplify,

t + 8 = 3t + 4

Inverse operations,

t + 8 = 3t + 4

   -4          -4

t + 4 = 3t

-t         -t

4 = 2t

/2   /2

2 = t

Answer:

[tex]x = [2644,8418)[/tex]

Step-by-step explanation:

Given

[tex]f(x) = 86.3ln\ x - 680[/tex]

[tex]x < 8418[/tex]

Required

The domain of the function

The maximum value of x has been given.

So, the next step is to calculate its minimum value.

Since f(x) represents the % moisture. This value cannot go less than 0.

So, we set f(x) to 0; in order to calculate the minimum of x.

This gives:

[tex]f(x) = 0[/tex]

[tex]86.3ln\ x - 680 = 0[/tex]

Add 680 to both sides

[tex]86.3ln\ x - 680 + 680= 0 + 680[/tex]

[tex]86.3ln\ x = 680[/tex]

Divide both sides by 86.3

[tex]ln\ x = \frac{680}{86.3}[/tex]

[tex]ln\ x = 7.88[/tex]

Take exponent of both sides

[tex]e^{(ln\ x)} = e^{7.88[/tex]

[tex]x = e^{7.88[/tex]

[tex]x = 2644[/tex]

Hence, the domain is:

[tex]x = [2644,8418)[/tex]

or

[tex]2644 \le x< 8418[/tex]

Answer:

Answer:

x=17!

Step-by-step explanation:

3x+5=5x-29

5=2x-29

34=2x

Therefore x=17!

Answer:

x = 17

Step-by-step explanation:

Lets start evaluating

3x + 5 = 5x - 29

3x + 5 + 29 = 5x

3x + 34 = 5x

34 = 5x - 3x

34 = 2x

x = 34/2

x = 17

Answer:

Prism Y

[tex]Height = 12in[/tex]

[tex]Length = 6in[/tex]

[tex]Width = 4in[/tex]

[tex]Volume = 288in^3[/tex]

Prism Z

[tex]Height = 18in[/tex]

[tex]Length =10in[/tex]

[tex]Width = 10in[/tex]

[tex]Volume = 1800in^3[/tex]

[tex]Total = 2088in^3[/tex]

Step-by-step explanation:

Given

See attachment for sculpture

Solving (a) The dimension and volume of Y

From the attachment

[tex]Height = 18 - 6[/tex]

18 in is the height of Z and 6in represents the length (height) of the unoccupied space by Y

So:

[tex]Height = 12in[/tex]

[tex]Length = 16 - 10[/tex]

16 in is the total length of the sculpture and 10 in represents the length of Z

So:

[tex]Length = 6in[/tex]

[tex]Width = 10 - 6[/tex]

10 in is the width of Z and 6in represents the length (width) of the unoccupied space by Y

So:

[tex]Width = 4in[/tex]

Hence, the dimension of Y is:

[tex]Height = 12in[/tex]

[tex]Length = 6in[/tex]

[tex]Width = 4in[/tex]

Volume is then calculated as:

[tex]Volume = Length * Width * Height[/tex]

[tex]Volume = 12in * 6in * 4in[/tex]

[tex]Volume = 288in^3[/tex]

Solving (b) The dimension and volume of Z

As identified in (a), the dimensions of Z are:

[tex]Height = 18in[/tex]

[tex]Length =10in[/tex]

[tex]Width = 10in[/tex]

Volume is then calculated as:

[tex]Volume = Length * Width * Height[/tex]

[tex]Volume = 18in * 10in * 10in[/tex]

[tex]Volume = 1800in^3[/tex]

Solving (c): Total volume of the sculpture.

To do this, we simply add up the volumes of Y and Z.

So, we have:

[tex]Total = 288in^3 + 1800in^3[/tex]

[tex]Total = 2088in^3[/tex]

(0,0) and (6,0)

First we subtract 18x from both sides

3x²-18x=0

Factor out a 3x

3x(x-6)=0

This means that x is either 0 or 6

Answer:

3×^2=3^3

or; same base get canceled so

x^2=3

hence x=√3

Answer:

21

Step-by-step explanation:

Answer:

1/2

Step-by-step explanation:

To find the slope given two points, use the slope formula

m= ( y2-y1)/(x2-x1)

   = ( 5-1)/(2--6)

    = (5-1)/(2+6)

    = 4/8

    = 1/2

Answer:

slope = [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 6, 1) and (x₂, y₂ ) = (2, 5)

m = [tex]\frac{5-1}{2+6}[/tex] = [tex]\frac{4}{8}[/tex] = [tex]\frac{1}{2}[/tex]

Answer:

35 meters

Step-by-step explanation:

Since 1cm=10meters, we can do 3.5cm=how many meters?

To get from 1 to 10 we multiply by 10.

So we can do 3.5x10 to get 35 meters.
