Find the length of side x in simplest radical form with a rational denominator

Answer:

32.5%

Step-by-step explanation:

The percentage decrease of available credit in Dylan's account is 30%. This was found by subtracting the new available credit from the original, dividing the difference by the original available credit, and multiplying by 100.

To calculate the percentage decrease of the available credit in Dylan's account, we need to first determine the amount of credit that has been used. The original available credit was $650.00, and it has decreased to $455.00 after some purchases. The difference between the two amounts is $650.00 - $455.00 = $195.00. This value represents the decrease in available credit.

Next, we calculate the percentage decrease by dividing the decrease by the original amount and multiplying by 100. So, the percentage decrease = ($195.00 / $650.00) × 100 = 30%.

Answer:

120 dollars

Step-by-step explanation:

6 hours per day, for 2 days, leads to a total of 12 hours (2*6 = 12)

If it takes 2 gallons of gas to run the boat for 1 hour, then it will take 24 gallons to run for 12 hours. We can see this if we have the ratio below

2 gallons: 1 hour

12*(2 gallons): 12*(1 hour) .... multiply both sides by 12

24 gallons: 12 hours

Now multiply this gallon count (24) by the cost per gallon ($5) and we get to 5*24 = 120

Answer:

arithmetic

Step-by-step explanation:

It is  arithmetic because the terms go up by 15 . That is the common difference is 15.

Answer:

it is an arithmetic sequence

Step-by-step explanation:

general formula of arithmetic progression is

an=a1+(n-1)d

we are given

a1=1

a2=16

we can find d

d=a2-a1=16-1=15

d=a3-a2=31-16=15

d=a4-a3=46-31=15

as we can see that there is a common difference d =15 between successive terms  of the this sequence

hence it is a arithmetic sequence

Answer:

Area = 20.52 cm^2 and Perimeter = 28.68 cm.

Step-by-step explanation:

Use Pythagoras theorem to find the base of the triangle.

a^2 = 6^2 - 3^2 =  27

a = sqrt27

b^2 = 9^2 - 3^2 =  72

b = sqrt72

Base = sqrt27 + sqrt72

= 13.68

So Area = 0.5 * 13.68 * 3

= 20.52 cm^2   (answer)

Perimeter = 9 + 6 + 13.68

= 28.68  ( answer).

Answer:

Jack is 6 and Mom is 30

Step-by-step explanation:

J = Jacks age

M = Mom's age

5J = M

In 6 years, so add 6 to the age

3(J+6) = (M+6)

We have a system of 2 equations and 2 unknowns

Lets simplify the 2nd equation

3(J+6) = (M+6)

3J + 18 = M+6

Substituting M =5J

3J + 18 = 5J +6

Subtract 3J from each side

3J-3J + 18 = 5J-3J +6

18 = 2J+6

Subtract 6 from each side

18-6 = 2J+6-6

12 = 2J

Divide each side by 2

12/2 = 2J/2

6=J

Jack is 6

We still need to find Mom's age

M = 5J

     = 5*6

    =30

Mom is 30

Answer:

Correct choice is D

Step-by-step explanation:

Plot points (12, 16), (13, 18), (13, 10), (14, 16), (15, 9), (15, 8), (16, 17), (17, 23) on the coordinate plane. On this coordinate plane x represents age in years and y represents texting speed in words per minute.

Option A is false. Consider points A(12,16) and C(13,10). For these points x-coordinates increases, but y-coordinates decreases. Therefore, as age increases, texting speed doesn't increase.

Option B is false. Consider points A(12,16) and B(13,18). For these points both x-coordinates and y-coordinates increases. Therefore, as age increases, texting speed increases too.

Option C is false. Consider points C(13,10) and F(15,8). For these points y-coordinates decreases, but x-coordinates increases. Therefore, as texting speed decreases, age increases.

Option D is true, there is no clear relationship between age and texting speed.

Answer:

The Answer is D. No, there is no clear relationship between age and texting speed.

Step-by-step explanation:

Answer: w = 9 cm,   L = 23 cm

Step-by-step explanation:

P (Perimeter)  = 2L(length) + 2w(width)

A (Area) = L (length) x w (width)

Use the formulas above to create a system of equations, then solve using the substitution method.

P = 2L + 2w

64 = 2L + 2w

32 = L + w

32 - w = L    ←←←   use this to substitute for L in the Area equation

                              A = L · w

                          207 = (32 - w)w

                          207 = 32w - w²

      w² - 32w + 207 = 0

         (w - 23)(w - 9) = 0

     w - 23 = 0            w - 9 = 0

           w₁ = 23                w₂ = 9

Now, solve for L:

      L₁ = 32 - w₁                      L₂ = 32 - w₂

         = 32 - 23                           = 32 - 9

          = 9                                    = 23

We have 2 sets of solutions (w₁ , L₁) and (w₂ , L₂)

                                              (23, 9)  and  (9, 23)

Notice that they are the same values but in reverse order.  These are the dimensions of the rectangle.  We generally consider width (w) to have the smaller value. So, w = 9 and L = 23

To find the size of a cube that David can cover with 169 quarts of paint, set up a proportion and solve for the edge length, David can cover a cube with an edge length of approximately 5.31 feet using 169 quarts of paint.

Explanation:

To find the size of a cube that David can cover with 169 quarts of paint, we need to use the direct proportion between the amount of paint and the surface area of the cube. Let x be the edge length of the cube. The surface area of a cube is given by[tex]6x^2[/tex]can set up the proportion:

[tex]16 quarts / 2 feet^2 = 169 quarts / (6x^2)[/tex]

Cross-multiplying and then solving for x, we get:

[tex]x^2 = (2^2 * 169) / 16[/tex]

[tex]x^2 = 28.1875[/tex]

x = sqrt(28.1875)

x ≈ 5.31 feet

Therefore, David can cover a cube with an edge length of approximately 5.31 feet using 169 quarts of paint.

Answer:

Corresponding Parts of Congruent Figures. The word corresponding refers to parts that match between two congruent triangles. You can identify corresponding angles and corresponding sides. First, name the corresponding angles.

Step-by-step explanation:

In geometry, two figures are congruent if they have the same size and shape. To verify congruence, all corresponding sides and angles of two figures must match in size and measure. For instance, given two triangles ABC and DEF, they would be congruent if their corresponding sides and angles were equal.

In geometric terms, two figures are congruent if they have the same size and shape. This means all corresponding sides and angles of the two figures are equal. In order to determine if two shapes are congruent, you need to match each part of one shape with a corresponding part on the other and see if they are of the same size and angle.

For instance, if you have two triangles ABC and DEF, these triangles would be congruent (often written as △ABC≅△DEF) if the sides AB=DE, BC=EF, and AC=DF and angles ∠A=∠D, ∠B=∠E and ∠C=∠F. This is the principle of corresponding parts of congruent figures being congruent.

In this equation l, y is the amount of cheese produced in billions of pounds and x represents the number of years after 2003.

a. To find the total cheese production in the country in 2006 we will substitute x= 3 in our given equation as 2006-2003=3.

[tex]y=8.3*(1.04)^{3}[/tex]

[tex]y=8.3*1.124864[/tex]  

[tex]y=9.3363712[/tex]

Therefore, the cheese production in year 2006 will be 9.34 billions of pounds.

b. To find the total cheese production in the country in 2017 we will substitute x= 14 in our given equation as 2017-2003=14.

[tex]y=8.3*(1.04)^{14}[/tex]

[tex]y=8.3*1.7316764476028035[/tex]

[tex]y=14.37291451510326905[/tex]

Therefore, the cheese production in year 2017 will be 14.37 billions of pounds.

Answer:

Given the equation: [tex]y = 8.3(1.04)^x[/tex]        ......[1]

where

y is the amount of cheese produced in billions of pounds and

x represents the number of years after 2003

Since, this equation models the cheese production in the country from 2003 to 2009.

(a)

Substitute x = 3 years(i.e, 2003 -2006) in [1] to solve for y;

[tex]y = 8.3(1.04)^{3}[/tex]

Simplify:

y = $9.3363712

Therefore, the total cheese production in the country in 2006 is, $9.34.

(b)

we use  the equation to predict the total amount of cheese produced in the country in 2017.

We have x = 14 years.

Substitute in [1] we get;

[tex]y = 8.3(1.04)^{14}[/tex]

Simplify:

y = $14.3729145151

Therefore, the estimate total amount of cheese produced in the country in 2017 is, $14.37
