Which of the following ratios is closest to the golden ratio? a. 5/3
b. 7/5
c. 10/8
d. 14/11
Answer:
A 5/3
Step-by-step explanation:
The fraction closest to the golden ratio is a. 5/3.
What is a golden ratio?The golden ratio is a ratio between two numbers that approximate 1.618.
It is sometimes referred to as the golden number, the golden proportion, or the divine proportion.
It is closely related to the Fibonacci sequence, a set of numbers where each number is added to the previous one and is typically written as the Greek letter Ф.
From the given options,
5/3 = 1.66.
7/5 = 1.4.
10/8 = 1.25.
14/11 = 1.27.
So, the closest ratio is 1.6 which is 5/3.

What percent of 438 is 106? Let p= the percent.
Let's create a simple proportion.
p = Percent
p/100 = 106/438
Now, cross multiply.
438p = 10,600
Divide both sides by 438 to isolate p.
p ≈ 24.200913242
Therefore, 106 is approximately 24.201 percent of 438.
106 is 24% of 438.
What is percentage?A relative value indicating hundredth parts of any quantity.
Given that, a number 438
Let p be the percent,

y = 7x + 3
Find the x and y intercepts of the line
Answer:
The x-intercept of the line is [tex]-\frac{3}{7}[/tex]
The y-intercept of the line is 3
Step-by-step explanation:
If the equation of a line is y = m x + b, then
The x- intercept is the value x at y = 0, (that means, the line intersect the x-axis at point (x, 0)The y-intercept is the value of y at x = 0, (that means, the line intersect the y-axis at point (0, y)Let us use these facts to solve the question
∵ y = 7x + 3
→ Substitute y by 0 to find the x-intercept
∵ y = 0
∴ 0 = 7x + 3
→ Subtract 3 from both sides
∵ 0 - 3 = 7x + 3 - 3
∴ -3 = 7x
→ Divide both sides by 7 to find x
∵ [tex]-\frac{3}{7}[/tex] = [tex]\frac{7x}{7}[/tex]
∴ [tex]-\frac{3}{7}[/tex] = x
∴ The x-intercept of the line is [tex]-\frac{3}{7}[/tex]
∵ y = 7x + 3
→ Substitute x by 0 to find the y-intercept
∵ x = 0
∴ y = 7(0) + 3
∴ y = 0 + 3
∴ y = 3
∴ The y-intercept of the line is 3

Piper used 1/5 meter of ribbon to create a border around a triangle if each side of the triangle is the same length how much ribbon did Piper use for each side?
Answer:
[tex]\frac{1}{15}[/tex]
Step-by-step explanation:
as said in the question that the triangle has three equal sides. i.e. this is an equilateral triangle. So,
let us consider one side of the triangle to be x . and 3x( x+x+x) should be equal to 1/5
[tex]x+x+x = \frac{1}{5}\\3x=\frac{1}{5}\\x = \frac{1}{5} / 3\\x = \frac{1}{5} * \frac{1}{3}\\x = \frac{1}{15}[/tex]
Slope of (3, -9) (3, 18)
Answer:
Undefined.
Step-by-step explanation:
To calculate the slope between two points on a graph, we use [tex]\frac{y2-y1}{x2-x1}[/tex].
Once we substitute in the provided points, this becomes [tex]\frac{18-(-9)}{3-3}[/tex].
Simplify to [tex]\frac{27}{0}[/tex].
This does not give us a number and instead results in an undefined slope, aka a vertical line.
