If the length of an arc intercepted by a central angle of 1.25 radians is 32 inches, which proportion could be used to find the

radius of the circle?
1.25/2π = 32/πr^2
1.25/360 = 2πr/32
1.25/2π = 2πr/32
1.25/2π = 32/2πr

Answer:

Option 4: 1.25/2π = 32/2πr

Step-by-step explanation:

Arc length = (theta/2pi) × 2pi × r

32 = (1.25/2pi) × 2pi × r

1.25/2pi = 32/(2pi × r)

sergejj [24]

Answer:

Here, b represents one loaf of bread and m represents the one gallon of milk.

As per the statement:

Arah went to the grocery store and bought 4 loaves of bread and 1 gallon of milk for $12.

⇒4b+m = 12  

It is also given that the next week, Sarah bought 2 loaves of bread and 3 gallons of milk for $13.50.

⇒2b+3m = 13.50

Then; system of equation :

4b+m = 12                   .....[1]

2b+3m = 13.50           .....[2]

Solve for b and m using above system of equations.

Multiply equation [2] by 2 we get;

4b+6m = 27              .....[3]

Subtract equation [1] from [3] we get;

4b+6m - 4b -m= 27-12

Combine like terms;

5m= 15

Divide both sides by 5 we get;

m = $3

Substitute the value of m in equation [1] we get;

4b+3 = 12

Subtract 3 from both sides we get;

4b=9

Divide both sides by 4 we get;

b = $2.25

Therefore, cost of one loaf of bread (b) and one gallon of milk (m) are:

$2.25 ad $3
