Answer:

15 meters and 25 meters long

Step-by-step explanation:

<em>There are 2 pieces of rope</em>.

Total length of both---> 40 meters

Length of piece 1 ------> x

Length of piece 2 -----> x + 10

<em>Find the value of x.</em>

<em>Form an equation ----> Length of piece 1 + length of piece 2 = total length</em>

x + (x + 10) = 40

2x + 10 = 40

2x = 30

x = 15

Length of piece 1 --> x ---> 15

Length of piece 2 --> x + 10 ----> 15 + 10 = 25

Therefore, one piece is 15 meters long and the other piece is 25 meters long.

Answer:

<em>p - </em>4

Step-by-step explanation:

Since there are 48 paintings being donated by 12 collectors, then we can say that each collector will donate 4 paintings.

This means Sergio has 4 less paintings than before which was represented by <em>p.</em> So, our expression is <em>p </em>- 4.

Find the area of the shaded region.
Anvisha [2.4K]

Answer:

73.4 cm^2

Step-by-step explanation:

The equation is :

πr^2

Substitute the radius in:

π(5)^2

Solve:

Area of full circle = 25π

(Note : leave this answer in terms of 'pi' so it is easier to handle

Next, find the area of the sector

The equation for this is:

(angle/360) x πr^2

Substitute the values in:

(80/360) x π(5)^2

Solve :

Area of sector = (50/9)π

Now, find the area of the triangle:

1/2 absinC

Substitute the values in:

1/2(5)(5) x sin(80) = 12.31009691

Subtract this answer from the area of the sector

Answer = 5.14319607

Subtract this from the area of the whole circle

Answer = 73.39662073

To the nearest tenth, that would be 73.4 cm^2

In triangle ABC, AB = 90 in., BC = 80 in., and angle B measures 50°. What is the approximate perimeter of the triangle?
Monica [59]

Answer:

The answer to your question is Perimeter = 287.3 in

Step-by-step explanation:

AB = 90 in

BC = 80 in

∠B = 50

Perimeter = ?

Process

1.- We need to find AC using Law of sines

\frac{sin A}{80} = \frac{sin 50}{90}

       sin A = \frac{80}{90} sin 50

       sin A = 0.68

              A = 42.9 ≈ 43

The sum of the internal angles in a triangle equals 180°

       A + B + C = 180°

       43 + B + 50 = 180

       B = 180 - 43 - 50

       B = 87°

\frac{AC}{Sin 87} = \frac{90}{sin 50}

AC = 90 \frac{sin 87}{sin 50}

      AC = 117.3

2.- Find the perimeter

     Perimeter = AB + BC + AC

     Perimeter = 90 + 80 + 117.3

     Perimeter = 287.3 in
