Answer:

1.95 m

Step-by-step explanation:

The ratio between the parent's height and the child's height stays the same.

Therefore, 9:6 = 1.5:1.

1.5:1 = x:1.3

Hence, after calculation, the parent's height is 1.95 m.

Answer:

y = 15

Step-by-step explanation:

We need to solve for k

y = x

21 = 7k  Divide both sides by 7 to solve for k

3 = k

y = xk

y = 5(3)

y = 15

Answer:

27

Step-by-step explanation:

\(11x^{2} -3x*y^3\)

Now we replace the variables by the numbers given.

\(11(3)^2-3(3)*2^3\)

We use PEMDAS, (parentheses, exponents, multiplication, division, addition, subtraction)

First we solve the exponents.

\(11(9) - 3(3) * 8\)

Next the multiplication, left to right

\(99-9*8\)

\(99-72\)

\(27\)

Answer:

Permuation; 210 possibilites

Step-by-step explanation:

With permutations we care about the order of the elements, whereas with combinations we don’t. For this question order matters, because you have two different positions you want to fill (captain, and co-captain).

This would be written as 15p2

To find the number of possibilities we want to use the permuation equation.

(,)=!(−)!

P=permutation

n= the set or population (15 soccer players)

r= subset (1 captain and 1 co-captain, total of 2)

(,)=(15,2)

=15!(15−2)!

= 210

If u are confused about !(factorial) in the equation here is a quick explanation

Many calculators have a factorial key (look for the ! symbol). This function of the calculator will automate the multiplications, but if you do not have a calculator that can compute factorials you just have to go like this

1! = 1

2! = 2 x 1 = 2

3! = 3 x 2 x 1 = 6

4! = 4 x 3 x 2 x 1 = 24

5! = 5 x 4 x 3 x 2 x 1 = 120

6! = 6 x 5 x 4 x 3 x 2 x 1 = 720

7! = 7 x 6 x 5 x 4 x 3 x 2 x 1 = 5040

8! = 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1 = 40320

9! = 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1 = 362880

10! = 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1 = 3628800

etc

Hope this helps!!

The number of possibilities in choosing captain and co-captain are 210 ways.

Permutations are different ways of arranging objects in a definite order. It can also be expressed as the rearrangement of items in a linear order of an already ordered set. The symbol nPr is used to denote the number of permutations of n distinct objects, taken r at a time.

Given that, a team of 15 soccer players needs to choose a captain and a co-captain.

Number of captains can be choose from 15 players.

Number of co-captains can be choose from 15-1=14 players.

So, the number of possibilities= 15×14

= 210 ways

Therefore, the number of possibilities in choosing captain and co-captain are 210 ways.

Answer:x5

Step-by-step explanation:Let's solve your equation step-by-step.

4x+2=2x+12

Step 1: Subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

Step 2: Subtract 2 from both sides.

2x+2−2=12−2

m ≤ -20

Step-by-step explanation:

-20and all the numbers less than -20 are a solution.  I know that -20 is included because the point on it is solid.  If the point was hollow the answer would be m < -20

The answer is A. The slope of the line is rise/run = 4/2 = 2.1. This means that each kilometer costs $2.10. The y-intercept is 2.1, which means that the initial fee is $2.10. So the correct statement is: The slope is 2.1. This means that each kilometer costs $2.10.

The other statements are incorrect. The slope is not 5, so each kilometer does not cost $5. The y-intercept is not 5, so the ride does not last 5 kilometers. The y-intercept is the value of the function when the input is 0, which in this case is the initial fee of $2.10.

Important info:

- Sophia has $6 to spend on lunch

- Concession stands sell sodas for $0.75

- All of their food items for $1.50

- Pretend she buys one drink

- Find the maximum amount of food she can buy now.

Process:

Subtract 600 and 75 since $6 = 600 cents

600 - 75 = 525

So Sophia has $5 and 25 cents left

Each food item is worth $1.50 which is 150 cents and she currently has $5.25 which is 525 cents

So divided 525 and 150

525 / 150 = 3.5

Unfortunately she can't buy half of a food item so the answer would be 3

Final Answer:

3, Sophia can buy 3 food items after buying 1 drink

Answer: what was the original price?

Step-by-step explanation:

To solve for y, you can start by isolating y on one side of the equation by moving all the terms that do not contain y to the right-hand side of the equation.

In this case, you can do this by subtracting 10 from both sides of the equation:

y - 10 = 5/6x + 10 - 10

This simplifies to:

y - 10 = 5/6x

Then, you can add 10 to both sides of the equation to get:

y = 10 + 5/6x

So, the solution for y is y = 10 + 5/6x.

A minimum of 51 miles must be driven in one day for option A to be cheaper than b.

under option (A) a fixed charge of $20 is to be paid plus $0.10 per mile.

whereas under option (B) only variable charges are to be paid at $.50 per mile.

how many miles should one drive so that cost under both situations is equal?

let's assume miles driven in a day is x

$20+ $0.1 x = $0.5 x

x = 50

if 50 miles are driven in a day cost under both situations is equal and more than that cost under option A will be less, therefore, the miles to be driven in a day should be greater than equal to 51 miles

Answer:

\(f^{-1}\left(f(576)\right)=\boxed{576}\)

\(f^{-1}(-7)+f(-7)=\boxed{13}\)

Step-by-step explanation:

The inverse of an invertible function with the domain of all real numbers is obtained by reflecting the original function across the line y = x, which swaps the input and output values of the function. Therefore, (x, y) → (y, x).

Given table:

\(\begin{array}{lrrrrrr}\vphantom{\dfrac12}x&-7&11&-13&6&5&-9\\\cline{1-7}\vphantom{\dfrac12}f(x)&7&12&8&-7&13&5\end{array}\)

Inverse function:

\(\begin{array}{lrrrrrr}\vphantom{\dfrac12}x&7&12&8&-7&13&5\\\cline{1-7}\vphantom{\dfrac12}f^{-1}(x)&-7&11&-13&6&5&-9\end{array}\)

If we have a function f(x), the inverse function is denoted as f⁻¹(x), and it has the property that f⁻¹(f(x)) = x for all valid inputs x in the domain of f(x).

Therefore:

\(\large\boxed{f^{-1}\left(f(576)\right)=576}\)

The value of f(-7) is the value of f(x) when x = -7. Therefore, reading from the original table, f(-7) = 7.

The value of f⁻¹(-7) is the value of f⁻¹(x) when x = -7. Therefore, reading from the inverse function table, f⁻¹(-7) = 6.

Therefore:

\(\large\boxed{\begin{aligned}f^{-1}(-7)+f(-7)&=6+7\\&=13\end{aligned}}\)

Answer:

A) solution 2 is more acidic than solution 1

Step-by-step explanation:

A chemist prepares two acid solutions:

Solution 1: 3 parts sulfuric acid to 7 parts water

Ratio of sulphur to water: 3/7 (3:7)

Solution 2: 4 parts sulfuric acid to 9 parts water

Ratio of sulphur to water: 4/9 (4:9)

___________________________________________________

Part A: (using ratios to determine which solution is more acidic)

First we make same denominator, since the denominators are 9 and 7, we have to find the lcm (lowest common multiple) they both have with is 63. To do that, we must multiply the denominators with either 7 or 9.

Solution 1: Numerator (3) multiplied by 9 and then denominator (7) multiplied by 9. This makes out fraction/ratio 27/63

Solution 2: Numerator (4) multiplied by 7 and then denominator (9) multiplied by 7. This makes out fraction/ratio 28/63

Since 28/63 (or just 28) is a larger quantity than 27/63 (or just 27) this means solution 2 is more acidic than solution 1.

Mathematical Line (Not sure what you would call this lol): 28 > 27

Part B: (Let 'y' amount of sulfuric acid mix with 'x' amount of water)

Equation of solution 1: y = 3/7x

Equation of solution 2: y = 4/9x

Please find attachment for graph.

Part C: Don't have a graph, sorry! (part a. method is more preferred to find more acidic because it gives the actual acidic amount.)
