50 pts and brainliest. Is the ratio of arc length to r always equal to pi? What is it equal to?
Please only answer if you know it, this is super important!! If it's right I'll mark you brainliest!
Answer:
It can sometimes be equal to π. However, it is equal to our central angle.
Step-by-step explanation:
First, recall that arc length is given by:
[tex]s=r\theta[/tex]
Where s is the arc length, r is the radius, and θ is the central angle of the arc in radians.
So, the ratio of the arc length to the radius is:
[tex]\displaystyle \frac{r\theta}{r}[/tex]
The radius r cancels. Hence, we are left with:
[tex]=\theta[/tex]
So, the ratio of the arc length to the radius does not equal π (although it can sometimes if the central angle is π radians (or 180°)). Rather, the ratio is equivalent to the central angle.
So, for example, if we have a circle with radius 7 with a central angle of 3π/2 (this gives us an arc length of 21π/2), then the ratio of the arc length to the radius will be 3π/2 (our central angle).
Answer:
Sometimes it can be equal to π. It is equal to our central angle.
Step-by-step explanation:
Recalling arc length is given by:
Where s is the arc length, r is the radius, and θ is the central angle of the arc in radians.
So, the ratio of the arc length to the radius is:
rθ/θ
The radius r cancels. Hence, we are left with:
= θ

Thirty-two cyclists make a seven-day trip. Each cyclist requires 8.33 kilograms of food for the entire trip. If each cyclist wants to eat an equal amount of food each day, how many kilograms of food will the group be carrying at the end of Day 5?
Answer:
76.16 kilograms of food
Step-by-step explanation:
Number of cyclist = 32
Food per cyclist = 8.33 kilograms
Days of the trip = 7 days
Food per cyclist per day = 8.33 kg / 7
= 1.19kg food per day for each cyclist
how many kilograms of food will the group be carrying at the end of Day 5?
5 days out of 7 days = 2 days
Each cyclist will have to carry = 2 × 1.19 kg of food for the remaining two days
= 2 × 1.19
= 2.38 kilograms of food for two days
32 cyclist for 2 days = 32 × 2.38 kg of food
= 76.16 kilograms of food
The group will be carrying 76.16 kilograms of food at the end of Day 5

Answer:
Its $28.548
Step-by-step explanation:
Because 10 percent of 23.4 is 2.34 and times that by two is 4.68, but then you have to find that 2 percent so I found the 1 of percent of it which is .234. So since you want 2 percent multiply .234 by two so then just add 4.68 and youll get the answer .

SIMPLIFY TO A SINGLE POWER OF 6:
[tex]\dfrac{6^5}{6} = \dfrac{6^5}{6^1} = 6^{5-1} = 6^4[/tex]
Answer:
6^4
Step-by-step explanation:
Since we aren't given a power in the denominator we can rewrite it as 6^1 since that equals 6 either way. Use the rule [ x^y/x^z = x^y-z ] to rewrite as a single power. Thus, 6^5-1 = 6^4.

which equation represent the line that passes through the point(-3.4,8.3) and has a slope of 6.5
Answer:
y - 8.3 = 6.5(x + 3.4) {the point-slope form of the equation}
y = 6.5x + 30.4 {the slope-intercept form of the equation}
65x - 10y = - 304 {the standard form of the equation}
Step-by-step explanation:
The point-slope form of equation is: y - y₀ = m(x - x₀), where (x₀, y₀) is any point the line passes through and m is the slope.
m = 6.5
(-3.4, 8.3) ⇒ x₀ = -3.4, y₀ = 8.3
The point-slope form of the equation:
y - 8.3 = 6.5(x + 3.4)
So:
y - 8.3 = 6.5x + 22.1 {add 8.3 to both sides}
y = 6.5x + 30.4 ← the slope-intercept form of the equation
y - 6.5x = 30.4 {multiply both sides by (-10)}
65x - 10y = - 304 ← the standard form of the equation

J = K (1+ p/100) make p as a subject
Answer:
p = 100(J/K - 1)
Step-by-step explanation:
When we want to make a variable the subject of an equation, we want to get that variable by itself on one side of the equation - to unwrap it from all the operations attached to it.
Here's what the process looks like for p:
[tex]J=K(1+p/100)\\J/K=1+p/100\\J/K-1=p/100\\p=100(J/K-1)[/tex]

Thirty minutes before a concert, there were 1,200 people in the 3,000-seat auditorium where the concert was being held. Five minutes before the concert, the auditorium was 90% full. Which of these equations can be used to determine p, the number of people who entered the auditorium during this time interval?
Answer: p = 1500
Step-by-step explanation:
Initially, there were 1200 people.
After the given interval, we know that the auditorium is 90% full (where the auditorium can hold a maximum of 3000 people)
Then after the interval, the number of people in the auditorium is equal to the 90% of 3000.
When we have a percentage X of a quantity A, the quantity of the percentage X is:
N = (X/100%)*A
In this case, the 90% of 3000 is equal to:
N = (90%/100%)*3000 = 0.9*3000 = 2700.
Then, at the beginning of the interval there were 1200 people, and at the end there were 2700.
The difference is:
p = 2700 - 1200 = 1500
This means that the number of people who entered the auditorium dirung the time interval is 1500.
