Find the length of each arc. Use the exact answer

Mathematics
1 answer:
xenn [34]3 years ago
7 0

Answer:

D) 16π/3 ft

Step-by-step explanation:

We solve the above question using the Arc length formula when our central angle is in degrees

The formula is given as:

Arc length = 2πr × θ /360

r = 4 ft

θ = Central angle in degrees = 240°

Hence,

2 × π × 4 × 240/360

8π × 240/360

8π × 20/30

16π/3 ft

Arc length = 16π/3 ft

Option D is the correct option

Which number(s) below belong to the solution set of the inequality Check all that apply. x + 30 < 60 a.50 b.45 c.300 d.1 e.29
Igoryamba

Answer:

e.29 d.1

Step-by-step explanation:

  • x+30<60 :

we will replace with the values we have :

  • 300 that's a big number . Obviously it isn't a solution
  • 50 : 30+50 = 80>60 so no
  • 45: 30+45= 75 >60  so no
  • 30+30 = 60 we have < not ≤ so no
  • 1 yes . it's obvious
  • 29 +30 = 59<60 so yes !

We can use a ratio expression to find the answer to this problem.

Set up the ratio.
4/5 = x/25
Multiply both sides by 25.
100/5 = x
Divide by 5.
20 = x
This means out of 25 times the ball is kicked toward the goal, the goalie will block it 20 times.

Please help me!!!!!!!!!!!!!!?
OLEGan [10]
So what you want to do for all of these is move the variable that you want to be the subject to one side of the equation and the other ones to the other side, then divide.

For example:

With number 1, m = 3n + 2p, since you want to make p the subject, first single out p by subtracting 3n from both sides.

m - 3n= 3n + 2p - 3n

2p = m - 3n

Then divide everything by 2.

2p / 2 = m/2 - 3n/2

p = , you could also say 1/2m - 3/2n

p = 1/2m - 3/2n

Next question: just do the same thing.

a = 3c - 4

a + 4 = 3c - 4 + 4

3c = a + 4

/3      /3   /3

c = 1/3a + 4/3

Next question: same process.

P - 2a = 2a - 2a + 2b

2b = P - 2a

/2     /2    /2

b = 1/2P - a
