find the value of JW given that JW=6x+2 and JB=10x+1

Answer:

1) 5

2) 25

Step-by-step explanation:

Since a square has equal sides, we have 4x=2x+10

2x=10

x=5

The area of a square is 5 squared, which is 25.

Answer:

C=diameter x pi

radius + radius = diameter

6+6=12

12 x 3.14 = 37.68

8 x 3.14 = 25.12

_____________

Radius x radius x pi = area

diameter / 2 = radius

8/2=4

4 x 4 = 16 x 3.14 = 50.24

6 x 6 = 36  x 3.14 = 113.04

_______________

6 km circle has  circum of 37.68 and area of 113.04

8 km circle has circum of 25.12 and area of 50.24

Answer:

Water (H2O)

Step-by-step explanation:

When hydrocarbons undergo combustion reactions (I.e reactions with oxygen) carbon (iv) oxide and water are usually produced.

In this case, the only difference is the numbe of moles between the product and reactant

Equation of reaction;

2C₂H₆ + 7O₂ → 4CO₂ + 6H₂O

Reactants:

1. Ethane = C₂H₆

2. Oxygen = O₂

Product:

1. Carbon(iv) oxide = CO₂

2. Water = H₂O

Answer:

H20

Answer:

66

Step-by-step explanation:

Answer:

y=66

Step-by-step explanation:

Start with the angle that has the purple arrow pointing to it.  Next to it, part of the right angle is 27 degrees so you subtract that from 90 degrees, which makes you get 63 degrees.  The measurement of all a triangle's angles is 180 degrees, so you add 63 and 51 to get 114, then subtract 114 from 180 to get 66 degrees.

Answer:

volume of a hemisphere ≈ 36369.5 in³

Step-by-step explanation:

To find the formula for calculating the volume of a hemisphere, we will follow the steps below:

write the formula for calculating the volume of a hemisphere.

volume of a hemisphere = volume of a sphere ÷2

                                        = [tex]\frac{4}{3}[/tex]πr³   ÷   2

                                        =[tex]\frac{2}{3}[/tex] πr³

where r is the radius

from the question given, diameter = 51.8 inches

but diameter = 2r , this implies that r = [tex]\frac{d}{2}[/tex]    hence   r = [tex]\frac{51.8}{2}[/tex] = 25.9 inches

π is a constant and is ≈ 3.14

we can now proceed to insert the values into the formula

volume of a hemisphere    =[tex]\frac{2}{3}[/tex] πr³

                                                =[tex]\frac{2}{3}[/tex] × 3.14 ×25.9³

                                                =[tex]\frac{2}{3}[/tex] × 3.14×17373.979

                                                 ≈36369.5 in³ to the nearest tenth cubic inch.

volume of a hemisphere ≈ 36369.5 in³

Answer:

n =7

Step-by-step explanation:

(n+1) +1 + (n-1) = value  first row

3+ (2n-9) +n = value   second row

The value has to be the same

Set the equations equal

(n+1) +1 + (n-1) =3+ (2n-9) +n

Combine like terms

2n+1 = 3n-6

Subtract 2n from each side

2n+1-1 -2n = 3n-6-2n

1 = n-6

Add 6 to each side

1+6 = n-6+6

7 = n

Answer:

n =7

Length of each ribbon = 5/8 yards

Length of 16 pieces of ribbon = 16* (5/8)

                                                  [tex]=16*\frac{5}{8}\\\\=2 * 5 \\\\=10[/tex]

The system of inequalities is y<x  and y<4.

In mathematics, "inequality" refers to a relationship between two expressions or values that are not equal to each other.

To solve the inequality, you may multiply or divide each side by the same positive number, add the same amount to each side, take the same amount away from each side, and more. You must flip the inequality sign if you multiply or divide either side by a negative number.

Given, the region is shaded y < 4.

And the region is not exceeding the x.

So, y<x.

Therefore, the system of inequalities is y<x  and y<4.

Answer:

                    aₙ = 6 + (n - 1)*7

a₃ = 6 + (3 - 1)*7 = 20

a₅ = 6 + (5 - 1)*7 = 34

a₁₁ = 6 + (11 - 1)*7 = 76

Answer:

Diagonal of television = 83 cm

Step-by-step explanation:

Width of television = 4x

height of television = 3x

Height of television = 49.8 cm

[tex] \therefore \: 3x = 49.8 \\ x = \frac{49.8}{3} \\ x = 16.6 \: cm \\ 4x = 4 \times 16.6 = 66.4 \: cm \\ \\ diagonal \: of \: television \\ = \sqrt{ {(66.4)}^{2} + (49.8)^{2} } \\ = \sqrt{ 4,408.96 + 2,480.04 } \\ = \sqrt{6,889} \\ = 83 \: cm \\ [/tex]

We have been given that last month Maria purchased a new cell phone for $500. The store manager told her that her cell phone would depreciate by 70% every 6 months.

We know that an exponential function is in form [tex]y=a\cdot (1-r)^x[/tex], where,

y = Final value,

a = Initial value,

r = Decay rate in decimal form,

x = Time in years.

Let us convert [tex]70\%[/tex] into decimal form.

[tex]70\%=\frac{70}{100}=0.70[/tex]

Initial value of car is 500, so [tex]a=500[/tex].

Since value of phone depreciates every  months, so value of phone will depreciate twice in a year.

Upon substituting our given values in exponential decay function, we will get:

[tex]V=500(1-0.70)^{2x}[/tex]

To find the value of phone after 2 years, we will substitute [tex]x=2[/tex] in our equation.

[tex]V=500(1-0.70)^{2(\cdot 2)}[/tex]

[tex]V=500(1-0.70)^{4}[/tex]

Therefore, option D is the correct choice.

Let us simplify our equation.

[tex]V=500(0.30)^{4}[/tex]

Therefore, option B is correct as well.

Answer: Isosceles

Step-by-step explanation:

Given: AB || DE ,  BC is a transversal

∠ABC ≅ ∠BCE by Alternate Interior Angles Theorem --> ∠BCE = 80°

∠DCA, ∠ACB, & ∠BCA are supplementary  --> ∠ACB = 50°

By the Triangle Sum Theorem, ∠A+∠B+∠C  = 180° --> ∠CAB = 50°

Triangle is isosceles because ∠A ≅ ∠C

Answer:

x = -4, x = 1

Step-by-step explanation:

x^2 + 3x - 4 = 0

4 and -1 add to 3 and multiply to -4.

(x+4)(x-1) = 0

Separate these by the Zero Product Property.

x+4 = 0

x-1 = 0

Solve.

x = -4

x = 1

Answer:The team failed to win 6 games.

Step-by-step explanation: 5/6 has to be equal to something over 36. Since you multiplied the denominator by 6 you have to multiply the numerator by 6 and 5*6 equals 30. If out of 36 games they won 30. Then to find how many games they lost all that you have to do is subtract 36 and 30 to get 6.

Regression to the mean occurs when the next generation regresses to the overall mean of the population.

Step-by-step explanation:

Regression to the mean occurs when the next generation regresses to the overall mean of the population. Extreme traits trend back to the average and are not increased or decreased in terms of measure. Measurable traits or characteristics that are extreme move back toward the average value. The next generation traits move back, or regress, to the average of that trait

Answer:

Regression to the mean is a statistical phenomenon that occurs whenever you have a nonrandom sample from a population and two measures that are imperfectly correlated.
