There are 27 animals in the barn. Some are geese and some are horses. There are 90 legs in all. How many of each animal are there
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

Using the numbers 1 2 3 4 5 6 7 8 place each number once in the appropriate box so that the final answer is an ancient approximation of Pi
The approximated value of π using the integer digits 1 2 3 4 5 6 7 8 is is 3.142857
How to approximate the value of π?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

Nabhitha has a collection of vintage action figures that is worth $420. If the collection appreciates at a rate of 13% per year, what equation would represent the value of the collection after 6 years?
Answer:
498
Step-by-step explanation:
dI'd the math
The equation that represents the value of collection after 6 years is $420 + 54.6(6).
What is an expression?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 function f(x) = –x^3 + 7x^2 – 7x – 15 has zeros located at 5, 3, –1. Verify the zeros of f(x) and explain how you verified them. Describe the end behavior of the function.
Answer:
See below for answers and explanations
Step-by-step explanation:
If we check x=5:
[tex]f(5)=-(5)^3+7(5)^2-7(5)-15\\f(5)=-125+7(25)-35-15\\f(5)=-125+175-50\\f(5)=50-50\\f(5)=0[/tex]
So [tex]x=5[/tex] is indeed a zero

[tex]f(3)=-(3)^3+7(3)^2-7(3)-15\\f(3)=-27+7(9)-21-15\\f(3)=-27+63-36\\f(3)=36-36\\f(3)=0[/tex]
So [tex]x=3[/tex] is also indeed a zero
If we check x=-1:

A is directly proportional to B. When A = 12, B = 3
Find the value of A when B = 3
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
