Answer:15$
Step-by-step explanation:
A swing hangs from a beam 10 feet high, with the seat hanging 2 feet above the ground. In motion, the swing moves back and forth from -130° to -50° to the horizontal. How far forward and back does the swing move along the ground at the extremes?
Answer:
11.17 ft
Step-by-step explanation:
Since the swing hangs from a beam 10 feet high with the seat hanging 2 feet above the ground, the swing moves in an arc of radius r = 10 ft - 2 ft = 8 ft.
Now, since the swing moves back and forth from -130° to -50° to the horizontal, the length of arc L it moves in is given by
L = Δθ/360 × 2πr where Δθ = change in angle of the swing = θ₂ - θ₁ where θ₁ = -50° and θ₂ = -130°. So, Δθ = θ₂ - θ₁ = -130° -(-50°) = -130° + 50° = -80°.
Substituting r and Δθ into L, we have
L = -80°/360° × 2π(8 ft)
= -8/36 × 16π ft
= -32π/9 ft
= -100.53/9 ft
= -11.17 ft
Ignoring the negative sign, the length of arc L = 11.17 ft. So, the swing moves back and forth 11.17 ft

Belinda went biking on Saturday and rode for 6\frac{4}{5} miles on Sunday she rode for \frac{2}{3} of the distance she rode on Sunday
Complete question :
Belinda went biking on Saturday and rode for 6 4/5 miles. On Sunday she rode for 2/3 of the distance she rode on Saturday. Write and solve an equation that will help you figure out how far Belinda rode on Sunday
Answer:
4.5333 miles
Step-by-step explanation:
Number of miles biked on Saturday = 6 4/5 miles
Miles on Sunday = 2/3 of miles biked on Saturday
To obtain the distance biked on Sunday :
Fraction of miles biked on Sunday * miles biked on Saturday
Miles biked on Sunday = 2/3 * 6 4/5
Miles biked on Sunday = 2/3 * 34/5
Miles biked on Sunday = (2 * 34) / (3 * 5) = 68/15 = 4.5333 miles

Joel has a goal to practice his clarinet for 4 ½ hours per week. The list below shows the number of hours Joel has practiced so far this week.
Answer:
3/4 hours
Step-by-step explanation:
Joel has a goal to practice his clarinet for 4 1/2 per week. The list below shows the number of hours Joel has a practiced so far for the week. Monday 1 1/2 hours Wednesday 1 1/4 hours Thursday 1 hour. How many more hours does he need to practice this week to meet his goal?
Total practice hours per week = 4 1/2 hours = 9/2 hours
Hours of practice so far for the week:
Monday = 1 1/2 hours = 3/2 hours
Wednesday = 1 1/4 hours = 5/4 hours
Thursday = 1 hour
Total = Monday + Wednesday + Thursday
= 3/2 + 5/4 + 1
= (6+5+4)/4
= 15/4 hours
How many more hours does he need to practice this week to meet his goal
Hours needed to meet goal = Total practice hours per week - Hours of practice so far for the week
= 9/2 - 15/4
= (18-15)/4
= 3/4 hours
Hours needed to meet goal = 3/4 hours

if the sum of the interior angles of a polygon is 2340, how many sides does the polygon have?
Answer:
15
Step-by-step explanation:
Where n represent no.of sides
(2n-4)90=2340
180n-360=2340
180n=2340+360
180n=2700
n=15

The value of x is ___, and the value of y is ___.
Answer:
I think x is 60 and y is 50.
Step-by-step explanation:
70 + 50 = 120
180 - 120 = 60
x = 60
50 + 50 = 100
70 + 60 = 130
130 + 100 = 230
230 - 180 = 50
y = 50
I hope this helps u! :D
Answer:
x=60 y=50
Step-by-step explanation:
180 is equal to the whole triangle so 50+70=120 and 180-120= 60
the other triangle has a missing value by doing the same thing before we can figure out that the missing value is 70. 70+x which is 60 equals 130. A straight line is equal to 180 so 180-130= 50.

Ethan hits 4 ringers in 10 attempts while throwing horseshoes. What does an experimental probability of 2/5 describe?
Your answer:
O P (horseshoes)
O P (missed shots)
O P (attempts)
O P (ringers)
Answer: P (ringers)
Step-by-step explanation:
This probability is simplified from 4/10 to 2/5
Since he got 4 ringers out of 10 attempts
we can tell that this probability stands for Ringers
