A store had 250 bottles of water. Each week, 40% of the bottles were sold and 48 new bottles arrived in shipments.
Which recursive function best represents the number of bottles of water in the store, given that f(0) = 250?
A. f(n) = f(n − 1) ⋅ 0.6 + 48, n > 0
B. f(n) = 250 − f(n − 1) ⋅ 0.4 + 48, n > 0
C. f(n) = f(n − 1) ⋅ 0.4 + 48, n > 0
D. f(n) = 250 − f(n − 1) ⋅ 0.6 + 48, n > 0
pls give reason
Answers
Answer:
A
Step-by-step explanation:
Given:
Initial number of bottles = 250
Every week = 40% is sold and 48 bottles arrive.
Week 1 = 250 - (250 x 0.40) + 48 = 250 - 100 + 48 = 198
Week 2 = 198 - (198 x 0.40) + 48 = 198 - 79 + 48 = 167
Answer is: A. f(n ) = f(n - 1) • 0.6 + 48, n > 0.

Recall that negative exponents indicates that we need to move the base to the other side of the fraction line.
(The "1's" in the simplifications above are for clarity's sake, in case it's been a while since you last worked with negative powers. One doesn't usually include them in one's work.)
In the context of simplifying with exponents, negative exponents can create extra steps in the simplification process.

What is the fraction 24/4 simplified?
Answers
Answer:
6
Step-by-step explanation:
The fraction 24/4 simplified is 6.
To simplify the fraction 24/4, we find the greatest common divisor (GCD) of the numerator (24) and the denominator (4), and then divide both the numerator and denominator by the GCD to obtain the simplified form.
Step 1: Find the GCD of 24 and 4.
The factors of 24 are 1, 2, 3, 4, 6, 8, 12, and 24.
The factors of 4 are 1 and 4.
The GCD of 24 and 4 is 4, as it is the largest number that divides both 24 and 4.
Step 2: Divide both the numerator and denominator by the GCD.
24 ÷ 4 = 6
4 ÷ 4 = 1
So, the simplified form of 24/4 is 6/1. However, any fraction divided by 1 remains the same, so the simplified fraction is 6.
Therefore, 24/4 simplified is 6.

a city has a garden in the shape of an equilateral triangle with 40 feet sides. there is a walkway that runs from a gate located at the midpoint of one side of the equilateral triangle to a fountain at the opposite vertex. approximately how long is the walkway?
Answers
Answer:
The walkway is approximately 34.64 feet long
Step-by-step explanation:
The length of the sides of the equilateral triangle shaped the city garden = 40 feet
The path of the walkway = From the midpoint of a side to the opposite vertex
Therefore, we have;
Let x, represent the length of the walkway
We have that the x, a side of the equilateral triangle, and half the side of the location of the gate, forms a right triangle, with a side of the equilateral triangle representing the hypotenuse side
Therefore, we have;
40² = x² + (40/2)²
40² = x² + 20²
x² = 40² - 20² = 1200
x = √1200 = 20·√3
The length of the walkway = x = 20·√3 ≈ 34.64 feet.

A person who weighs 105 pounds on Earth weighs 175 pound on the moon How much does a pound person weigh on the moon?
Answers
Answer:
1.67 pounds
Step-by-step explanation:
The problem above can be solved by using "direct proportion." This proportion shows that as one quantity increases, the other quantity increases and vice-versa.
Step 1: Represent the weight of the person on the moon by n.
Step 2: Set up a proportion.
[tex]\frac{105}{175}[/tex] = [tex]\frac{1}{n}[/tex]
Step 3: Cross multiply.
105 x n = 175 x 1
105n = 175
Step 4: Find n by dividing both sides by 105.
n = [tex]\frac{175}{105}[/tex]
n = 1.666 or 1.67 pounds (lowest term)
A pound of person on Earth will weigh 1.67 pounds on the moon.

Length = x m
Width = 3⅔ = 11/3
Area = 44 m²
Area of rectangle = length × width
Plug in the values into the equation
[tex] 44 = x \times \frac{11}{3} [/tex]
[tex] 44 = \frac{11x}{3} [/tex]
Multiply both sides by 3
[tex] 44 \times 3 = \frac{11x}{3} \times 3 [/tex]
[tex] 132 = 11x [/tex]
Divide both sides by 11
[tex] 12 = x [/tex]
x = 12
