An arc of length 30 m : l = 30 m.
r = 15 m,  ∠ A = ?
Formula for the length of an arc is:
 l = r π A / 180°  ( where A is the central angle )
A = l · 180 / r π = ( 30 · 180 ) / ( 15 · 3.1415926 ) = 114.43 °
This is very close to your result.

DeShawn uses 3/4 of a box of rice to cook dinner. The portion he uses weighs 12 ounces. Write and solve and equation to find the
Dovator [93]
3/4 box = 12 oz

we first need to find 1/4 of a box. to do that divide both sides by 3

1/4 box = 4 oz

for a full box which is 4/4 multiply both sides by 4

1/4 x (4)  = 4 x (4) oz

4/4 ( or one whole) = 16 oz

Let F (x; y) = xy2i + x2y j. Evaluate ∫F.ds (from c to [infinity]) where C is the upper half of the circle of radius 1 centered
77julia77 [94]

Answer:

The integral \int F \bullets ds is 0.

Step-by-step explanation:

A parameterization of curve C can be:

X (t) = cost 0 <= t <= pi

Y (t) = sint 0 <= t <= pi

r (t) = costi + sintj

r '(t) = -sinti + costj

Fds = [-costsin^3t + sintcos^3t] dt

The integral \int F \bullets ds is given by:

\int _0^{\pi }\left[-costsin^3t + sintcos^3t dt\right]dt

= \int _0^{\pi }-sin ^3tcostdt + \int _0^{\pi }sintcos^3tdt = 0

Is the number a multiple of 8? Write yes or no. 4, 8, 20, 40.WHAT IS MULTIPLE
BARSIC [14]

Consider two integers x,y. We say that x is a multiple of y if x is evenly divisible by y:

\dfrac{x}{y} = k,\quad x,y,k \in \mathbb{Z}

Alternatively, we can say that x is a multiple of y if there exists an integer k such that x = ky

So:

  • 4 is not a multiple of 4, because 4/8 is not an integer.
  • 8 is a multiple of 8, because 8/8=1
  • 20 is not a multple of 8, because 20/8 is not an integer
  • 40 is a multiple of 8, because 40/8=5

Mr.Reddrick has a 74 total yards of red and blue felt to distribute to students in his art class. Each of his 20 students gets 2
svet-max [94.6K]

Answer:

A. 1.2 yd

Step-by-step explanation:

We are informed that Mr.Reddrick has a 74 total yards of red and blue felt to distribute to students in his art class. Moreover, we also have the information that each of his 20 students gets 2.5 yards of blue felt for the project. This implies that the total blue felt distributed is;

20*2.5 = 50 yards

The remainder is the total red felt left for distribution;

74 - 50 = 24 yards

Since we have 20 students, each one of them receives;

24/20 = 1.2 yd
