Three lions and three tigers are walking in a row to get ice cream. The lions are fighting so they are not walking next to each other. in how many different ways can the three lions and three tigers walk if no two lions are the same and no two tigers are the same?
Answers
Answer:
72
Step-by-step explanation:
As 3 lions & 3 tigers are to be arranged in a way that lions are not together. It can be done as per following arrangements
LTLTLT , or TLTLTL
Lions can be positioned in six ways, Tigers can also be positioned in 6 ways. There are two alternative positions.
Hence the arrangement can be done in 2 x 6 x 6 = 72 ways
The different ways should be 72.
calculation:As 3 lions & 3 tigers are to be arranged
So, it can be
LTLTLT , or TLTLTL
Now the arrangement should be
[tex]= 2 \times 6 \times 6[/tex]
= 72 ways

Micah pays 54$ for an item originally priced 60$. What percentage of the original price was his discount?
Answers
Answer: The percentage of the original price was his discount = 10%
Step-by-step explanation:
Given: original price = $60
Price after discount = $54
Discount = Price after discount - original price
= $ (60-54) = $6
The percentage of the original price was his discount = [tex]\dfrac{Discount}{Original\ price}\times100[/tex]
[tex]=\dfrac{6}{60}\times100\%\\\\=\dfrac{1}{10}\times100\%\\\\=10\%[/tex]
Hence, the percentage of the original price was his discount = 10%

If triangle JKL is similar to triangle RST then the value of x is 15.
What is Triangle?A triangle is a three-sided polygon that consists of three edges and three vertices.
Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion .
Triangle JKL is similar to triangle RST
Let us find the value of x by forming a proportional equation
10/x = 8/12
Apply cross multiplication
120=8x
Divide both sides by 8
x=15
Hence, if triangle JKL is similar to triangle RST then the value of x is 15.

?/h=h/?
Answers
Answer:
The quadratic equations and their solutions are;
9 ± √33 /4 = 2x² - 9x + 6.
4 ± √6 /2 = 2x² - 8x + 5.
9 ± √89 /4 = 2x² - 9x - 1.
4 ± √22 /2 = 2x² - 8x - 3.
Explanation:
Any quadratic equation of the form, ax² + bx + c = 0 can be solved using the formula x = -b ± √b² - 4ac / 2a. Here a, b, and c are the coefficients of the x², x, and the numeric term respectively.
We have to solve all of the five equations to be able to match the equations with their solutions.
2x² - 8x + 5, here a = 2, b = -8, c = 5. x = -b ± √b² - 4ac / 2a = -(-8) ± √(-8)² - 4(2)(5) / 2(2) = 8 ± √64 - 40/4. 24 can also be written as 4 × 6 and √4 = 2. So x = 8 ± 2√6 / 2×2= 4±√6/2.
2x² - 10x + 3, here a = 2, b = -10, c = 3. x =-b ± √b² - 4ac / 2a =-(-10) ± √(-10)² - 4(2)(3) / 2(4) = 10 ± √100 + 24/4. 124 can also be written as 4 × 31 and √4 = 2. So x = 10 ± 2√31 / 2×2 = 5 ± √31 /2.
2x² - 8x - 3, here a = 2, b = -8, c = -3. x = -b ± √b² - 4ac / 2a = -(-8) ± √(-8)² - 4(2)(-3) / 2(2) = 8 ± √64 + 24/4. 88 can also be written as 4 × 22 and √4 = 2. So x = 8 ± 2√22 / 2×2 = 4± √22/2.
2x² - 9x - 1, here a = 2, b = -9, c = -1. x = -b ± √b² - 4ac / 2a = -(-9) ± √(-9)² - 4(2)(-1) / 2(2) = 9 ± √81 + 8/4. x = 9 ± √89 / 4.
2x² - 9x + 6, here a = 2, b = -9, c = 6. x = -b ± √b² - 4ac / 2a = -(-9) ± √(-9)² - 4(2)(6) / 2(2) = 9 ± √81 - 48/4. x = 9 ± √33 / 4 .

4x + 3(4x + 7) = 4(7x + 3)
Answers
Answer: 1
Step-by-step explanation:4x + 3(4x + 7) = 4(7x + 3) + -3
Reorder the terms:
4x + 3(7 + 4x) = 4(7x + 3) + -3
4x + (7 * 3 + 4x * 3) = 4(7x + 3) + -3
4x + (21 + 12x) = 4(7x + 3) + -3
Reorder the terms:
21 + 4x + 12x = 4(7x + 3) + -3
Combine like terms: 4x + 12x = 16x
21 + 16x = 4(7x + 3) + -3
Reorder the terms:
21 + 16x = 4(3 + 7x) + -3
21 + 16x = (3 * 4 + 7x * 4) + -3
21 + 16x = (12 + 28x) + -3
Reorder the terms:
21 + 16x = 12 + -3 + 28x
Combine like terms: 12 + -3 = 9
21 + 16x = 9 + 28x
Solving
21 + 16x = 9 + 28x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-28x' to each side of the equation.
21 + 16x + -28x = 9 + 28x + -28x
Combine like terms: 16x + -28x = -12x
21 + -12x = 9 + 28x + -28x
Combine like terms: 28x + -28x = 0
21 + -12x = 9 + 0
21 + -12x = 9
Add '-21' to each side of the equation.
21 + -21 + -12x = 9 + -21
Combine like terms: 21 + -21 = 0
0 + -12x = 9 + -21
-12x = 9 + -21
Combine like terms: 9 + -21 = -12
-12x = -12
Divide each side by -12.
x = 1
Simplifying
x = 1
(Brainliest for correct) You have decided to buy a Honda Accord LX, but you are concerned about the value of the car depreciating over time. You search the Internet and obtain the following information. The suggested retail price is $20,025. The depreciation per year is $1,385. What is the value of the car in dollars for 1 year of ownership, and how did you get that answer?
Answers
To find the value of the car after 1 year, subtract the amount it depreciates from the value of the car:
20,025 - 1,385 = 18,640
After 1 year the car is valued at $18,640
Answer:
$18640
Step-by-step explanation:
For year 1: Depreciated value is $1385.
We will minus that amount from the actual worth of car i.e. $20,025
So,
= $20,025 - $1385
= $18640

Step-by-step explanation:
c is the length of the side. a is the altitude. b is the base. a is the vertical bisector if the base, so the base is 0.5 cm.
c² = a² + b²
1² = a² + 0.5²
1² - 0.5² = a²
