Help ASAP!! A Triangle Has Side Lengths Of 11in, 15in, And 20in. Find The Angle Measures Of The Triangle.

Answers

Answer 1

Answer:

<A = 47.7°

<B = 99.4°

<C = 32.9

Step-by-step explanation:

When given the measurements of all three sides, you can calculate the angles using the Cosine Law.

c² = a² + b² - 2ab cos C

(based on Pythagorean Theorem)

If we say: a = 15

b = 20

c = 11

11² = 15² + 20² - 2(15)(20) cos C

121 = 625 - 2(15)(20) cos C

121 = 625 - 600 cos C

⁻504 = ⁻600 cos C

cos⁻¹ (504 ÷ 600) = C

< C = 32.9°

a² = b² + c² - 2bc cos A

15² = 20² + 11² - 2(20)(11) cos A

225 = 521 - 2(20)(11) cos A

225 = 521 - 440 cos A

⁻296 = ⁻440 cos A

cos⁻¹ (296 ÷ 440) = A

<A = 47.7°

Then, since we know the sum of all three angles of a triangle equals 180°:

180° - 32.9° - 47.7° = 99.4°

<B = 99.4°

when we divide one time by 5, we simply take away 1 from the power making it

[tex] {5}^{2m - 1} [/tex]

the other options are wrong

[tex] {25}^{m - 1} [/tex]

would be right, if we have

[tex] {25}^{m} \div 25[/tex]

After deduction of 4 paisa in a Rupee a sum of Rs 720 is left.What was it originally?​

Answers

Given:

After deduction of 4 paisa in a Rupee a sum of Rs 720 is left.

To find:

The original amount.

Solution:

We know that,

1 Rs. = 100 paisa

After deduction of 4 paisa in a Rupee, we get

[tex]100-4=96[/tex]

It means Rs. 720 is the 96% of the original amount.

Let x be the original amount.

[tex]720=\dfrac{96}{100}x[/tex]

[tex]72000=96x[/tex]

[tex]\dfrac{72000}{96}=x[/tex]

[tex]750=x[/tex]

Therefore, the original amount is Rs. 750.

Answer:

68.1

Step-by-step explanation:

If those angles are congruent, then all side lengths follow the same ratio.

So the smaller triangle side length of 9 over the small side length of the bigger triangle 21.5, is the ratio for all the sides.

9/21.5 = unknown side / 48

unknown side = 48 * 9/21.5

So to find the length of CD, multiply 48 by our ratio to get ~ 20.1

Add that to our 48 and we get 68.1

the x-intercepts are at

x = -3

x = 0

x = 1

Step-by-step explanation:

ask the points, where the functional value is 0.

2x³ + 4x² - 6x = 0

we see that every term contains an expression of x. so, we can simplify this

x × (2x² + 4x - 6) = 0

so, one solution is plainly visible : x=0

for the other solutions we need to solve the square equation

2x² + 4x - 6 = 0

or even simpler

x² + 2x - 3 = 0

the solution of a square equation is

x = (-b ± sqrt(b² - 4ac))/(2a)

in our case

a=1

b=2

c=-3

x = (-2 ± sqrt(2² - 4×1×-3))/(2×1) = (-2 ± sqrt(4 + 12))/2 =

= (-2 ± sqrt(16))/2 = (-2 ± 4)/2 = -1 ± 2

x1 = -1 + 2 = 1

The sum of -4 and the difference of 3 and 1

Answers

Answer: -2


Step 1: Write an equation

Before we are able to solve, we need to write an equation. We can do this by breaking down the equation. We are told to find the sum of -4 and the difference of another two numbers. Sum means addition, so we will add -4 to the difference of 3 and 1. Because we are adding to the difference, we will put 3 and 1 inside of parentheses, and find the difference before we add. Knowing this, we can write the equation. Let’s do this now.

-4+(3-1)

Step 2: Solve

Now that we have the equation we can solve for the answer. Let’s start by finding the difference, as indicated by the parentheses. After that, we can find the sum of that number and -4 by adding them together. We can do this now.

-4+(3-1)
-4+2
-2

This is your answer! The sum of -4 and the difference of 3 and 1 is -2. Hope this helps! Comment below for more questions.

What is a quadratic equation?

A basic quadratic equation, or a second-order polynomial equation with a single variable, is represented by the equation x : ax² + bx + c = 0, where a≠0 for the variable x. As it is a second-order polynomial equation, which is ensured by the algebraic fundamental theorem, it must have at least one solution.

We can start by simplifying the quadratic equation:

y = (x + 3)² – 4

y = x² + 6x + 9 - 4

y = x² + 6x + 5

Now, we can use various methods to find values of x and y that satisfy this equation. Here are five possible values:

If we substitute x = -1, we get:

y = (-1)² + 6(-1) + 5

y = 0

So, one solution is (-1, 0).

If we substitute x = 0, we get:

y = 0² + 6(0) + 5

y = 5

So, another solution is (0, 5).

If we substitute x = -5, we get:

y = (-5)² + 6(-5) + 5

y = 0

So, another solution is (-5, 0).

To find rational solutions, we can factor in the quadratic expression:

y = x² + 6x + 5

y = (x + 1)(x + 5)

So, the solutions are x = -1 and x = -5. Substituting these values into the equation, we get:

For x = -1, y = (-1)² + 6(-1) + 5 = 0

For x = -5, y = (-5)² + 6(-5) + 5 = 0

So, the solutions are (-1, 0) and (-5, 0).

A 8 year old boy has 6 different toys and wants to put them all in a straight line.
In how many ways can this be done?

I would appreciate step by step, as I have no clue on how to solve. Thanks!

Answers

Answer:  720

============================================================

Explanation:

The number 8 from "8 year old boy" can be completely ignored. In my opinion, this is an (un)intentional distraction on your teacher's part.

There are 6 toys to arrange. The order is important.

For the first slot, there are 6 choices. Then the second slot has 5 choices (we cannot have a toy occupy more than one slot at a time).The third slot has 4 choices, and so on.

We have this countdown: 6,5,4,3,2,1

Those values multiply out to 6*5*4*3*2*1 = 720

There are 720 ways to arrange the 6 different toys. Order matters.

---------------------

An alternative approach is to use the nPr permutation formula with n = 6 and r = 6. We use a permutation because order matters.

The nPr formula is

[tex]_{n} P _{r} = \frac{n!}{(n-r)!}\\\\[/tex]

where the exclamation marks indicate factorial. For example, 6! = 6*5*4*3*2*1 = 720.

Answer:

Number of tickets sold = 11000

Ticket cost = $4

Probability that a ticket wins grand price = 1 / 11000

Probability that a ticket wins second price = 1 / 11000
