The formula for kinetic energy is:

KE = (1/2) * m * v^2

where KE is the kinetic energy, m is the mass of the object, and v is the velocity of the object.

We are given the mass of the pick-up truck as 1500 kg and its velocity as 31.0 m/sec. We can plug these values into the formula to calculate its kinetic energy:

KE = (1/2) * m * v^2

= (1/2) * 1500 kg * (31.0 m/sec)^2

= (1/2) * 1500 kg * 961.0 m^2/sec^2

= 720750 J

Therefore, the kinetic energy of the pick-up truck is 720750 Joules.

The probability of drawing a green ball in one draw is 8/14 = 4/7. Since the balls are replaced after each draw, each draw is independent of the others. Therefore, the probability of getting 6 green balls in a row is (4/7)^6 ≈ 0.066.

Rounding to three decimal places, the probability is approximately 0.066.

Vοlume οf the cylinder in will be 226.28 yd³, Vοlume οf Slanted cylinder is 141.37 in³ and Vοlume οf οblique cubοid is 1224 cm³.

What exactly is a cylinder?

In geοmetry, a cylinder is οne οf the fundamental 3d fοrms with twο parallel circular bases at a distance. The curving surface cοnnects the twο circular bases at a predetermined distance frοm the centre. The axis οf the cylinder is the line cοnnecting the centres οf twο circular bases. The height οf the cylinder is the distance between the twο circular bases.

A. Nοw,given that diameter οf base = 6 yd then radius=6/2=3 yd

and height will be =√10²-6²  (By Pythagοras theοrem )

= √64

= 8 yd

then vοlume οf cylinder is=πr²h

= 22/7*3*3*8

= 1584/7

= 226.28 yd³

Hence, Vοlume οf the cylinder  will be 226.28 yd³.

B. Vοlume οf Slanted cylinder is V = πr²h

V = π3²5

V = π × 3 × 3 ×5

V = 141.37 in³

Hence, Vοlume οf Slanted cylinder is 141.37 in³

C. Vοlume οf οblique cubοid is V = lwh

V = 17 × 18 × 4

V = 1224 cm³

Therefore ,Vοlume οf οblique cubοid is 1224 cm³.

A system of equations is the given term of math for two or more equations with the same variables. The solution of these equations represents the point of the intersection.

You can solve a system of equations by substitution or adding methods. In the addition method, you eliminate a variable, on the other hand, in the substitution method you replace a variable for the other.

Firstly, you should extract the main information of the question.

Next,  you should convert the given text information into equations. See below.

20A+10C=750 (1)

25A+20C=1200 (2)

From the substitution method, you can solve this question by following the steps below:

x = 2 is in the interval x ≥ 2 with f(x) = [tex]\sqrt{x-2}[/tex] , then

D. $128.94. is the total amount of money Nate will earn after taxes when he buys a CD for $1000  The formula for compound interest is:

A = P * (1 + r/n)^(nt), where A is the amount after t years, P is the principal amount, r is the interest rate as a decimal, n is the number of times interest is compounded per year, and t is the number of years.

We can use this formula to calculate the amount of money Nate will have after 5 years:

A = 1000 * (1 + 0.03/4)^(4 * 5) = 1000 * (1 + 0.0075)^20 = 1000 * 1.1629 = 1162.9

The interest earned is 1162.9 - 1000 = $162.9.

And the amount of interest taxed is 20% of $162.9, which is 20% * $162.9 = $32.58.

So, the total amount of interest earned after taxes is $162.9 - $32.58 = $130.32.

Therefore, the correct answer is D. $128.94.

As per the figure, the angle equation p + q + r = 180 is proved.

In geometry, an angle is defined as the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle. When two lines are parallel, the angles opposite to each other are called corresponding angles.

In the given figure AB || CD, we are asked to prove that the sum of angles p, q, and r is equal to 180 degrees. This can be proven using the concept of corresponding angles.

Since lines AB and CD are parallel, the angles opposite to each other are equal, i.e., p = r. Therefore, the sum of angles p and r can be represented as 2p.

Furthermore, since lines AB and CD are parallel, the alternate interior angles are equal. This means that angle q is equal to angle p.

Therefore, the sum of all three angles, p, q, and r, can be represented as 2p + q.

And since we know that p = q, we can simplify this to 3p.

Finally, since the sum of angles in a triangle is always 180 degrees, we know that

=> 3p = 180 degrees.

Solving for p, we find that p = 60 degrees.

Therefore, the sum of angles p, q, and r is equal to

=> 2p + q = 2 * 60 + 60 = 180 degrees,

which proves the statement p + q + r = 180 degrees.

The volume of the conical hole will be 154 cubic feet.

The area a cone takes up in a three-dimensional plane is known as its volume. A cone's base is circular, so it is made of a radius and a diameter.

Given that a cone-shaped hole is 3 feet deep and the circumference of the base of the hole is 44 feet,

The volume of the cone will be calculated as:-

Volume = (1/3)πr²h

The circumference of the cone is,

2πr = 44

2 x ( 22 / 7 ) x r =  44

r = 7 feet

The volume of the cone will be calculated as:-

Volume = (1/3)πr²h

Volume = ( 1 / 3 )  x ( 22 / 7 ) x 7 x 7 x 3

Answer: Let's denote the original number of pages Mark planned to read as "P".

From the first statement, we know that P - 18 pages will take 5 more days, which means P pages will take 5 days less, or 5 - 5 = 0 days.

From the second statement, we know that P - 24 pages will take 8 more days, which means P pages will take 8 days less, or 8 - 8 = 0 days.

So, we have two equations:

P - 18 = 5 * X

P - 24 = 8 * Y

Where X and Y are the number of pages Mark reads per day.

Since X and Y are equal, we can substitute one of them for the other:

P - 18 = 5 * (P - 24) / 8

Expanding the right side and solving for P, we find that P = 288 pages.

Answer:

Answer:

Let's first calculate the amount of interest that would be earned if the interest were compounded annually. The formula for the future value of a single sum is:

F = P * (1 + r/n)^(nt)

Where:

F is the future value

P is the principal (the initial deposit)

r is the annual interest rate

n is the number of compounding periods per year

t is the number of years

For our calculation, we have:

P = $10,000

r = 1.8% = 0.018

n = 1 (annual compounding)

t = 30

So, the future value of the account with annual compounding is:

F = $10,000 * (1 + 0.018/1)^(1 * 30) = $10,000 * (1.018)^30 = $21,784.08

Now, let's calculate the amount of interest that would be earned if the interest were compounded monthly. The formula for the future value of a single sum is the same, but we need to use the monthly compounding rate (r/12) instead of the annual rate and the number of months (12t) instead of the number of years:

F = P * (1 + r/n)^(nt)

Where:

F is the future value

P is the principal (the initial deposit)

r is the annual interest rate

n is the number of compounding periods per year

t is the number of years

For our calculation, we have:

P = $10,000

r = 1.8% = 0.018

n = 12 (monthly compounding)

t = 30

So, the future value of the account with monthly compounding is:

F = $10,000 * (1 + 0.018/12)^(12 * 30) = $10,000 * (1.0015)^360 = $22,254.51

The difference in the two future values is $22,254.51 - $21,784.08 = $470.43.

So, the account would be worth $470.43 more if interest were compounded monthly rather than annually over a period of 30 years. Round to the nearest dollar, the answer is $470.

The measure of side A'B' for the triangle A'B'C' is equal to 4 using a scale factor of 1/2 to dilate it.

Scale factor is the ratio between the scale of a given original object and a new object, which is its representation but of a different size either bigger or smaller.

The dilation if the triangle ABC implies it is bigger than the triangle A'B'C' with a scale factor 1/2 since AC = 10 and A'C' = 5

side A'B' = 8 × 1/2

side A'B' = 4

First, we need to find a common denominator between  [tex]\frac{5}{3}[/tex] and [tex]\frac{2}{9}[/tex].

A common denominator consists of two or more fractions that have the same denominator. This makes it easier to perform numeric equations, and to solve them.

To find the common denominator, we can multiply the denominators, 3 and 9.

Now we know that the two new fractions are going to have a denominator of 27.

Now, we can use these equations to solve for the numerator.

Now, the fractions look like this:

To add them together, we can use this equation:

To convert [tex]\frac{51}{27}[/tex] and [tex]\frac{17}{8}[/tex] into common denominators, we need to multiply the denominators, like we did above.

The price of one citron is 5 units and the price of one fragrant wood apple is 3.5 units." Let's call the price of one citron "c" and the price of one fragrant wood apple "w".

Using the information from the first equation:

4c + 3w = 34

Using the information from the second equation:

We can now solve the system of equations to find the value of "c" and "w".
