Answer:

The amount she started with $20

Step-by-step explanation:

Let the amount Ahmya started with = x

when she bought $10 shirt, the remaining money is = x - 10

she spent half of this remaining money on dinner = [tex](\frac{x- 10}{2} )[/tex]

amount left after this = [tex](\frac{x- 10}{2} )[/tex]

she further spent $4 on cofee, the remaining money = [tex](\frac{x- 10}{2} )[/tex] - 4

she also spent 1/4 of remaining money on souveniers = [tex]\frac{1}{4}(\frac{x-10}{2} - 4)[/tex]

amount left = [tex]\frac{3}{4}(\frac{x-10}{2} - 4)[/tex]

The two last fractions should sum up to 1;

[tex]\frac{1}{4}(\frac{x-10}{2} - 4) + \frac{3}{4}(\frac{x-10}{2} - 4) = 1\\\\\frac{x-10}{8} -1 + \frac{3x-30}{8} -3= 1\\\\\frac{x-10}{8} + \frac{3x-30}{8} = 1+3+1\\\\\frac{x-10}{8} + \frac{3x-30}{8} = 5\\\\\frac{x-10 +3x-30}{8} = 5\\\\\frac{4x-40}{8} =5\\\\4x-40 =40\\\\4x =80\\\\x = 20[/tex]

x = $20

Therefore, the amount she started with $20

The value of the angles are ∠2 = 68, ∠4 = 68, and ∠3 = 112.

The angle is defined as the span between two intersecting lines or surfaces at or close to the point where they meet.

Supplementary angles are the angles having a sum of 180 degrees.

∠1 + ∠4 = 180

112 + ∠4 = 180

∠4 = 180 -112= 68°

Vertically opposite angles are always equal.

∠4 = ∠2

∠2 = 68

Vertically opposite angles are always equal.

∠1 = ∠3

∠3 = 112°

Therefore, the value of the angles are ∠2 = 68, ∠4 = 68, and ∠3 = 112.

The rational root theorem is used to determine the potential roots of a function.

The potential roots are: [tex]\mathbf{-10, -5, 3, 15}[/tex]

The function is given as:

[tex]\mathbf{P(x) = x^3 + 6x^2 - 7x - 60}[/tex]

For a polynomial function:

[tex]\mathbf{P(x) = px^n +.............+ q}[/tex]

The potential roots are:

[tex]\mathbf{Roots = \pm \frac{Factors\ of\ q}{Factors\ of\ p}}[/tex]

The factors of 60 are:

[tex]\mathbf{60 = \pm 1, \pm 2, \pm 3, \pm 4, \pm 5, \pm 6, \pm 10, \pm 12, \pm 15, \pm 20, \pm 30, \pm 60}[/tex]

The factor of 1 is:

[tex]\mathbf{1 = \pm 1}[/tex]

So, we have:

[tex]\mathbf{Factors= \frac{\pm 1, \pm 2, \pm 3, \pm 4, \pm 5, \pm 6, \pm 10, \pm 12, \pm 15, \pm 20, \pm 30, \pm 60}{\pm 1}}[/tex]

Answer:

x- intercept = 2, y- intercept = - [tex]\frac{8}{7}[/tex]

Step-by-step explanation:

To find the x- intercept, let y = 0 in the equation and solve for x

4x - 7(0) = 8 , that is

4x = 8 ( divide both sides by 2 )

x = 2 ← x- intercept

To find the y- intercept , let x = 0 in the equation and solve for y

4(0) - 7y = 8, that is

- 7y = 8 ( divide both sides by - 7 )

y = - [tex]\frac{8}{7}[/tex] ← y- intercept

Answer:

I have the same questions and I got them right

Step-by-step explanation:

1.) P(2)=4/25

2.) P(4)= 5/25= 1/5

3.) P(2,3)=5/25= 1/5

4/25+1/25= 5/25= 1/5

4.) P(2,4,6)=16/25

4/25+ 5/25+ 7/25= 16/25

5.)There are three even numbers so, 3/6= 1/2. So, 1/2.

6.) P(1, 2, 3, 4, 5, 6)= 25/25 = 1

6/25+ 4/25+ 1/25+ 5/25+ 2/25+ 7/25= 25/25 = 1

P(1)= 6/25   P(2)= 4/25 P(3)= 1/25 P(4)= 5/25 P(5)= 2/25 P(6)= 7/25

Answer:

  Albert Einstein

Step-by-step explanation:

Einstein formulated the special and general theories of relativity, completely revising the laws of physics that had been accepted up to that point in time. Among many results was the equation saying matter and energy are the same thing:

  [tex]E = mc^2[/tex]

The change in kinetic energy of the car is -83439.06 joules.

The change in kinetic energy of an object is equal to the final kinetic energy minus the initial kinetic energy.

Since the car comes to rest after hitting the tree, its final kinetic energy is 0.

The initial kinetic energy of the car can be calculated using the formula KE = 1/2 m v², where KE is the kinetic energy, m is the mass of the object, and v is the velocity.

Plugging in the values, we get:

KE = 1/2 × 1622 kg × (11.3 m/s)²

KE = 1/2 × 1622 kg × 128.69 m²/s²

KE = 83439.06 kg m²/s²

To convert this value to joules, you can use the conversion factor 1 joule = 1 kg m²/s².

The change in kinetic energy of the car is equal to the final kinetic energy minus the initial kinetic energy, or 0 - 83439.06 kg m²/s² = -83439.06 kg m²/s².

Therefore, the car's kinetic energy dropped by -83439.06 joules.

Answer:

Step-by-step explanation:

1/3(12x+6x-21)

Take 1/3 of everything in the ()

4x+2x-7 combine like terms

6x-7

The equivalent expression is 6x - 7

Given the function 1/3(12x+6x-21), to get the equivalent expression, we will open the parenthesis using the distributive law;

= 1/3(12x+6x-21)

=  1/3(12x) + 1/3(6x) - 1/3(21)

= 4x + 2x - 7

On simplification, the resulting expression will be:

= 6x - 7

Hence the equivalent expression is 6x - 7

Given:

Granny Apples charge $12 for 6 pounds of apples.

Wilson' Apples charges $15 for 5 pounds of apples.

To find:

Which apple company provides a better deal.

Solution:

We need to compare unit price of both companies.

[tex]\text{Unit price}=\dfrac{\text{Total price}}{\text{Number of units}}[/tex]

Unit price of Granny Apples,

[tex]\text{Unit price}=\dfrac{\$12}{6}[/tex]

[tex]\text{Unit price}=\$2[/tex]

Unit price of Wilson Apples,

[tex]\text{Unit price}=\dfrac{\$15}{5}[/tex]

[tex]\text{Unit price}=\$3[/tex]

Since, per unit price of Granny Apples is less than Wilson Apples, therefore Granny Apples provides a better deal.

Answer: 13,12,5

Step-by-step explanation:

According to the triangles inequality : The sum of any two sides of a triangle must be greater than the third.

since [tex]6+5 =11 \ngtr 15[/tex]

[tex]20+10=30\ngtr40\\\\ 16+2=18\ngtr19[/tex]

Only pipe lengths with measure 13,12,5 can form triangle as

13+12 >5

12+5>13

13+5>12

Hence, the correct option is 13,12,5.
