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:

These parallel lines cross 1 line. Because they are parallel they will form the same angles on that line. Therefore, x+50 = 3x-100 since those angles are corresponding angles made by a pair of parallels.

To find x we need to find what value of x gives the same answer for 3x-100 and x+50 since those 2 angles are equal.

x+50 = 3x-100 - now all we need to do is solve for x:

x+50 = 3x-100

50=2x-100

150=2x

Answer:

0.786 L

Step-by-step explanation:

1000 ml to 1 L

(786 ml) / (1000 ml) = 0.786 L

0.786 L liquids of liter did the scientist to use for this experiment

Division is the process of splitting a number or an amount into equal parts.

here, we have,

A scientist used 786 milliliters of an liquid for an experiment.

we know,

1000 ml to 1 L

so, we get,

(786 ml) / (1000 ml) = 0.786 L

Hence, 0.786 L liquids of liter did the scientist to use for this experiment.

Son- s+5

7s+5 = 4(s+5)

7s+5 = 4s+20

3s = 15

s=5

2 years ago the son was 5 so Mr. Singh was 35

30000/60=500 hours

Answer:

8 hours and 20 minutes

Step-by-step explanation:

There are 5 days a week and Fitta spends 25 minutes each day.

25 x 5 = 125 minutes a week

125 x 4 = 500 minutes in 4 weeks

There are 60 minutes in an hour, so 500 divided by 60 = 8.3333

So the results are 8 hours and 20 minutes

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:

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

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

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.

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
