Answer:5/18

Step-by-step explanation:

1. Find how many minutes (90 minutes in all but you were there for 25)

2. Put 25 over 90 to find the probability in the time that you were not there.

3. Simplify the fraction to 5/18.

Answer:

A = 12

Step-by-step explanation:

We can define ratio a to b as 12:3. If we are finding the value of A when B is 3, we go to the ratio. The ratio says that when B is 3, A is 12. Therefore, A is 12.

Answer:

A = 12

Explanation:

Given:

A ∝ B

set "k" constant

A = k(B)

Find "k"

12 = k(3)

k = 4

Then find A when B = 3

A = k(B)

insert values found

A = 4(3)

A = 12

Answer:

There are 9 geese and 18 horses.

Step-by-step explanation:

Step 1: Make equations.

g ... number of geese

h ... number of horses

First equation: There are 27 animals in the barn.

g + h = 27

Second equation: There are 90 legs in all.

We know geese have two legs and horses 4.

2g + 4h = 90

Step 2: Solve the system of equations.

g + h = 27 (first equation)

2g + 4h = 90 (second equation)

Let's express g in terms of h in first equation.

g + h = 27

g = 27 - h

Now let's substitute g in second equation with g in first equation.

2g + 4h = 90

2(27 - h) + 4h = 90

And solve for h.

54 - 2h + 4h = 90

54 + 2h = 90

2h = 90 - 54

2h = 36

h = 18

Let's substitute the value of h back to first equation to get g.

g = 27 - h

g = 27 - 18

g = 9

The equation that represents the value of collection after 6 years is $420 + 54.6(6).

Mathematical actions are called expressions if they have at least two terms that are related by an operator and include either numbers, variables, or both. Adding, subtraction, multiplying, and division are all reflection coefficient operations. A mathematical operation such as reduction, addition, multiplication, or division is used to integrate terms into an expression.

As per the given data provided by the question,

The worth of the vintage collection = is $420

The price of the collection appreciates per year = by 13%

The price appreciates per year = 420 × 13/100 = $54.6.

So, the equation for n years is,

$420 + $54.6(n)

Where n is the number of years.

$420 + $54.6(6) = $747.6

The approximated value of π using the integer digits 1 2 3 4 5 6 7 8 is is 3.142857

The integers are given as:

1 2 3 4 5 6 7 8

The value of π is:

π = 22/7

Evaluate the quotient

π = 3.14285714286

From the question, the digits 1 to 8 have to appear just once.

So, we approximate the number up to the point where any of the given digits has more than one occurrence.

So, we have:

π = 3.142857

Hence, the approximated value of π is 3.142857

Answer:

[tex]\sf \tan(C)=\dfrac{3}{4}[/tex]

Step-by-step explanation:

First, find the missing side length (DE) by using Pythagoras' Theorem:

a² + b² = c²  

(where a and b are the legs, and c is the hypotenuse, of a right triangle)

⇒ 36² + DE² = 45²  

⇒ DE² = 45² - 36²

⇒ DE² = 729

⇒ DE = √729

The equation that can be determined by the coordinates for point B will be 25 = (x - 6)² + (y - 5)².

The study of geometry using points in space is known as coordinate geometry. This may be used to discover the length between the endpoints, the dividing line's m:n ratio, the line's mid-point, and so on.

Segment AB has point A located at (6, 5). If the distance from A to B is 5 units.

Then the equation that can be determined by the coordinates for point B will be
