Find the length of an arc made by a 180-degree central angle in a circle with a 10ft radius
mixas84 [53]

Answer:

the length of an arc = 10π ft.

Step-by-step explanation:

The length of an arc with angle Θ and radius r will be equal r * Θ

note the angle must be in radian

Given: Θ = 180° = π  and radius = r = 10 ft.

<u>So, the length of the arc = π * 10 = 10π ft.</u>

What does 101=50-h h means the number 49
ICE Princess25 [194]
Let me see if I understand your question:

101=50-h

this would just be an equation with a variable: this variable is "h". Variable is an unknown value, like a name for "something".

so we could say that 101 equals 50 minus "something" and we call this something "h"

this is what 101=50-h "means"

as it happens, we can find out the value of this h:

we can subtract 50 from both sides of the equation:

101-50=50-50-h
51=-h

and multiply by (-1)
-51=h

so our h is equal to -51.

so...  does not actually mean here 49...

tres cajas contienen cuatrocientas naranjas la primera tiene veinte naranjas mas q la segunda y treinta mas q la tercera cuantas
Lemur [1.5K]

Answer: Box3 has 120 oranges.

Box1 has 150 oranges.

Box  has 130 oranges.

Step-by-step explanation:

I will answer this in English.

The question says:

3 boxes have 400 oranges.

The first one has 20 more than the second and 30 more than the third.

So we have 3 equations:

box1 + box2 + box3 = 400

box1 = box2 + 20

box1 = box3 + 30

Now, we can take the variable box1 in the third equation and replace it on the other two.

box3 + 30 + box2 + box3 = 400

box3 + 30 = box2 + 20

Now we can isolate one of the variables in the second equation, let's isolate box2.

box2 = box3 + 30 - 20 = box3 + 10

now we can replace it in the other equation:

box3 + 30 + box2 + box3 = 400

box3 + 30 + box3 + 10 + box3 = 400

3*box3 + 40 = 400

3*box3 = 400 - 40 = 360

box3 = 360/3 = 120.

Box3 has 120 oranges.

Box1 has 120 + 30 = 150 oranges.

Box  has 150 - 20 = 130 oranges.
