The longer leg of a right triangle is 4cm longer than the shorter leg. the hypotenuse is 8cm longer than the shorter leg. find the side lengths of the triangle

Answers

Answer 1
Longer leg = x + 4

Shorter leg = x

Hypotenuse = x + 8


Using Pythagorean Theorem:

a^2 + b^2 = c^2

(x + 4)^2 + x^2 = (x + 8)^2

x^2 + 8x + 16 + x^2 = x^2 + 16x + 64

2x^2 + 8x + 16 = x^2 + 16x + 64

2x^2 +8x = x^2 + 16x + 48

2x^2 - 8x = x^2 + 48

x^2 - 8x = 48

x^2 - 8x - 48 = 0

You can complete the square from here or use the quadratic formula.

Completing the square:

x^2 - 8x = 48

x^2 - 8x + (-8/2)^2 = 48 + (-8/2)^2

x^2 - 8x + 16 = 48 + 16

(x - 4)(x - 4) = 64 or (x - 4)^2 = 64

x - 4 = +√64 OR x - 4 = -√64

x - 4 = +8 OR x - 4 = -8

x = 12 OR x = -4

However, you can't use negative 4 as a length because your length needs to be a positive.

So x will be 12.


Shorter leg: 12

Longer leg: 12 + 4

Hypotenuse: 12 + 8

Answer 2

Final answer:

To find the side lengths of the right triangle, we let the shorter leg be x cm, resulting in the longer leg and hypotenuse being (x + 4) cm and (x + 8) cm, respectively. Using the Pythagorean theorem, we establish the equation x² + (x + 4)² = (x + 8)², then solve for x to determine the side lengths.

Explanation:

The problem involves solving for the lengths of the sides of a right triangle using the Pythagorean theorem. Let the shorter leg of the triangle be x cm. According to the problem statement, the longer leg would then be x + 4 cm, and the hypotenuse would be x + 8 cm. The Pythagorean theorem states that in a right triangle, the square of the hypotenuse (c) is equal to the sum of the squares of the other two sides (a and b).

Using the theorem we can set up the equation:

x² + (x + 4)² = (x + 8)²

Solving for x will give us the lengths of the sides of the triangle:

Shorter leg: x cmLonger leg: x + 4 cmHypotenuse: x + 8 cm

Angle AFC is a right angle so it measures 90 degrees. Angle CFB is 42 degrees which is given so angle AFC has to measure 48 degrees because when combined you get 90 degrees. Since AFC measures 48 degrees it is an acute. Again CFB is 42 degrees and CFD is a right angle which is 90 degrees. Angle DFB is the sum total of the two angles so angle DFB would measure 132 degrees which makes it an obtuse angle. CFD is a right so it is 90 degrees because all right angles measure 90 degrees.

How do you find the coordinates of the midpoint of segment VW with the end points of V(-2,-6) and W(x+2, y+3)

Answers

Final answer:

The coordinates of the midpoint of segment VW are (x/2, (y-3)/2).

Explanation:

To find the coordinates of the midpoint of segment VW, we can use the midpoint formula.

The midpoint formula states that the x-coordinate of the midpoint is the average of the x-coordinates of the endpoints, and the y-coordinate of the midpoint is the average of the y-coordinates of the endpoints.

Given the endpoints V(-2, -6) and W(x+2, y+3), we can find the x-coordinate of the midpoint by taking the average of the x-coordinates: (-2 + (x+2))/2.

Similarly, we can find the y-coordinate of the midpoint: (-6 + (y+3))/2.

So the coordinates of the midpoint are (x/2, (y-3)/2).

if a number is a natural number, then it is also a whole number? what is the Inverse, the Converse, the Contrapositive, and the Bi-Conditional? and what is the Truth value for each one?

Answers

Final answer:

The original statement, 'If a number is a natural number, then it is also a whole number' is true because every natural number falls into the set of whole numbers. However, its converse is not true, as whole numbers include 0, which is not a natural number, making the inverse and the bi-conditional false. The contrapositive of the statement is true, maintaining logical consistency.

Explanation:

If a number is a natural number, then it is indeed also a whole number. The relationship between natural numbers and whole numbers is an inclusive one, where all natural numbers (1, 2, 3, ...) are also whole numbers (0, 1, 2, 3, ...). The original statement can be expressed in logical form as: If P, then Q, where P is 'a number is a natural number,' and Q is 'it is also a whole number.'

Here is how the other forms of the statement look:

The inverse negates both the hypothesis and the conclusion: If not P, then not Q. So, 'If a number is not a natural number, then it is not a whole number.'

The converse switches the hypothesis and the conclusion: If Q, then P. For our statement, 'If a number is a whole number, then it is also a natural number.'

The contrapositive negates and switches the hypothesis and conclusion: If not Q, then not P. Therefore, 'If a number is not a whole number, then it is not a natural number.'

The bi-conditional states that P if and only if Q: A number is a natural number if and only if it is a whole number.'

The truth value of the original statement is true since all natural numbers are whole numbers. However, the converse is not true because whole numbers also include 0, which is not a natural number. Consequently, the inverse and the bi-conditional are false. The contrapositive is true because if it is not a whole number, then it can't be a natural number (considering that whole numbers include all natural numbers).

The probability that concert tickets are available by telephone is 0.91. for the same event, the probability that tickets are available through a web site is 0.96. assume that these two ways to buy tickets are independent. what is the probability that someone who tries to buy tickets both through the internet and by the telephone will obtain at least one ticket? round your answer to four decimal places (e.g. 98.7654).

Answers

Final answer:

The probability of obtaining at least one concert ticket through both the internet and by telephone is 0.9984.

Explanation:

The probability that someone who tries to buy tickets both through the internet and by telephone will obtain at least one ticket is 0.9984.

To calculate this, we first find the probability of not getting any tickets through either method: P(no tickets) = P(no tickets by phone) * P(no tickets online). Then, subtract this probability from 1 to get the probability of obtaining at least one ticket: P(at least one ticket) = 1 - P(no tickets).

Eddie purchased 4 packages of light bulbs and received a 15% discount. He also paid $4.85 in taxes on his purchase. Write an algebraic expression to represent the total amount Eddie paid. Let x represent the cost of each package purchased.

Answers

Okay. An algebraic expression we can use here is 4x * 0.85 + 4.85= t. I say this, because "x" equals the amount paid per package of light bulbs and he paid for 4 of them. He received a 15% discount for purchasing 4 packages of light bulbs, but he would still have to pay 85% (0.85 in decimal form) of the price. Then, $4.85 are added to his purchases. I put the "t" in the algebraic expression to represent the total cost of the purchase together, including tax and discount. The algebraic expression is 4x * 0.85 + 4.85.

1) 1+6
2) 2+5
3) 3+4
4) 4+3
5) 5+2
6) 6+1
So there are 6 ways to get a 7,

Hence P(of getting a sum =7) = 6/36 = 1/6 = 0.1667



Final answer:

When two dice are rolled, there are 6 feasible outcomes out of 36 that will sum to '7', hence the probability is 1 out of 6, or approximately 0.167.

Explanation:

In the field of probability, when you roll two dice, there are 6 possible outcomes for each die, hence giving us 36 possible outcomes altogether (6*6=36). Out of these 36 possible outcomes, there are 6 combinations that can total to '7'. These combinations are: (1,6), (2,5), (3,4), (4,3), (5,2), and (6,1). Therefore, the probability of rolling a '7' with two dice is 6 out of 36, which simplifies to 1 out of 6, or approximately 0.167, when rounded to three decimal places.

You have $20 to spend on taxi fare. The ride costs $5 plus $2.50, per mile.

Answers

it would be $2.50 per mile
I am assuming you are asking how many miles you can travel on the taxi.

In this situation a good method would be to make an equation.

Let x represent the number of miles traveled.
The ride costs $2.50 per mile, so the cost of the total trip is equal to 2.5x + 5. (the 5 is the base 5$ cost)

Set this equation equal to 20 as you have $20 to spend.

So, we get
2.5x + 5 = 20
Subtract 5 on both sides to get:
2.5x = 15
Divide by 2.5 on both sides to find x. 
x = 6

You can travel 6 miles in the taxi.

Talia is packing a moving box. She has a square-framed poster with an area of 9 square feet. The cube-shaped box has a volume of 30 cubic feet. Will the posture lie flat in the box?

Answers

We calculate for the dimensions (the length of the sides) of both the poster and the cube. If the length of the side of the poster is shorter compared to that of the box then, the poster will lie flat in the cube. However, if the poster has a length that is longer than that of the cube then, it will not lie flat in the cube.

length of the poster = sqrt (9 ft^2) = 3 ft
length of the cube = cbrt (30 ft^3) = 3.11 ft

Since, the length of the cube is longer compared to the length of the poster then, the poster will lie flat on the cube. 

Answer: Yes, the posture will be lie flat in the box.

Step-by-step explanation:

since we have given that

Area of square framed poster = 9 sq. feet

Volume of cube shaped box = 30 cubic feet.

As we know the formula for "volume of cube":

[tex]Volume=30\\\\a^3=30\\\\a=\sqrt[3]{30}=3.10\ feet[/tex]

So, Area of cube shaped box would be

[tex]6a^2=6\times (3.1)^2=57.9\ ft^2[/tex]

Since the cube box is large enough so that the posture will lie flat in the box.

Final answer:

Billy could drive 256.5 miles in 4.5 hours.

Explanation:

To find the number of miles Billy could drive in 4.5 hours, we will use the concept of direct variation. Direct variation states that when two variables are directly proportional, their ratio is constant.

Given that Billy drives 171 miles in 3 hours, we can set up a proportion:

Miles driven / Hours in the car = Miles driven / Hours in the car

Using the given values, we have:

171 / 3 = x / 4.5

To solve for x, cross multiply:

3x = 171 * 4.5

Divide both sides by 3:

x = (171 * 4.5) / 3

Simplifying the right side of the equation gives us:

x = 256.5

Therefore, Billy could drive 256.5 miles in 4.5 hours.

Identify a reflection about the x-axis or a reflection about the y-axis of ƒ(x) = 7x2 – x3 by observing the equation of the function g(x) = –7x2 + x3.

Answers

Final answer:

The function g(x) = –7x² + x³ is the reflection of the function f(x) = 7x² – x³ about the x-axis. This is observed by the change in signs of each term in the function's equation after performing the reflection.

Explanation:

By observing the given equation, f(x) = 7x² – x³ and g(x) = –7x² + x³, it is clear that the function f(x) reflects about the x-axis to create function g(x). This is indicated by the change of signs of each term in the equation of the function.

To elaborate, a reflection about the x-axis sees a function's equation change y(x) to -y(x). In our example, f(x) becomes -f(x) or –(7x² – x³), which after simplifying gives us –7x² + x³ = g(x). Therefore, g(x) is the reflection of f(x) about the x-axis.

Furthermore, to identify a reflection about the y-axis, observe if the equation changes from f(x) to f(-x). An even function or a function symmetric about the y-axis would not change with this transformation. Conversely, an odd function would change signs, just like our function did when reflecting over the x-axis.
