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

Put the numbers from least to greatest.

17, 6, -10, -7, -12, -12, -2, 16, -14 → -14, -12, -12, -10, -7, -2, 6, 16, 17

The median is the middle number of a data set.

-14, -12, -12, -10, -7, -2, 6, 16, 17

Therefore, the median is -7.

Best of Luck!

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]

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

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

We have given that,

Answer A is wrong: 5 + 2 + x

B ) The expression represents 5 plus 2 plus x.

5+2x=5+2x

This is a correct statement.

An expression, in math, is a sentence with a minimum of two numbers and at least one math operation in it.

Answer C is wrong: 5 + x + x

Answer D is wrong: 5 + x*x

E The expression represents the sum of 5 and 2x.

5+2x=5+2x

This is the correct statement.

Hello There. The correct answer to this is B. Because it shows that A = 4pr2 We need divide each term of 4pr2 = A r2 A-4p Then we need to do is Take the square root of both sides of the equation to eliminate the exponent on the left side. r = + A-4p Then completed of the solution is the result of both the positive and negative portions of the solution.

Step-by-step explanation:

CB and GF are the same side and u can see that CB is two times larger than GF so GH is two times smaller then CD

The solution is, the value of GH = 2, option A.

A scale factor is when you enlarge a shape and each side is multiplied by the same number. This number is called the scale factor. Maps use scale factors to represent the distance between two places accurately.

here, we have,

If CB = 6, GF = 3, and CD = 4,

and, we have to find GH.

from the given figures we get,

CB and GF are the same side and u can see that CB is two times larger than GF so GH is two times smaller then CD.

i.e. CB/GF = 6/3 = 2

scale factor = 2.

again, CD/GH = 2

So, GH = CD/2

            =2

Hence, The solution is, the value of GH = 2.

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.

Answer:

[tex]\dfrac{118}{135}[/tex]

Step-by-step explanation:

Total Number of Students =135

Number who took all three subjects=5

Number who took PE and BIO=10

Number who took PE and ENG=15

Number who took BIO and ENG=7

Therefore:

Total Number of students who took exactly two subjects=5+10+2=17

Therefore:

Number of students who did not take exactly two subjects=135-17=118

The probability that a randomly-chosen student from this group did not take exactly two subjects

[tex]=\dfrac{\text{Number of students who did not take exactly two subjects}}{\text{Total Number of students }} \\=\dfrac{118}{135}[/tex]

A 45-45-90 triangle has two legs that are the same length. So both legs are 4 in.

Area of the triangle = 1/2 x 4x4 = 8 square in.

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.
