During a musical an orchestra is playing. As the music plays, the volume changes in the beginning of the piece can be modeled by
noname [10]

Answer:

Kindly check explanation

Step-by-step explanation:

Given the model:

s = 10│x - 4│+ 50

s represents the sound level in decibels and x represents the number of measures of music played

To find x at s = 80

The equation becomes /

80 = 10│x - 4│+ 50

Subtract 50 from both sides of the equation

80 - 50 = 10 |x - 4| + 50 - 50

30 = 10 | x - 4 |

Divide both sides by 10

30/10 = 10|x - 4| / 10

3 = |x - 4|

|x - 4| is an absolute value expression

±3 = |x - 4|

x = 3 + 4 = 7

x = - 3 + 4 = 1

PLS I WILL GIVE BRAINLIEST
Nana76 [90]

Answer:

208 cm^2

Step-by-step explanation:

We can find the area of the net by adding up the area of each of the 6 rectangles that make up the net. Since two of each rectangle are the same, we only have to find the area of the 3 different sized rectangles and multiply each by 2.

Rectangle pairs are:

  • Left rectangle and right rectangle
  • Top rectangle and the rectangle above the bottom rectangle
  • Bottom rectangle and the rectangle surrounded by all for sides

Now, let's solve the question.

Left rectangle:

6 x 4 = 24, rectangle has area of 24 squared cm

Top rectangle:

6 x 8 = 48, rectangle has area of 48 squared cm

Bottom rectangle:

4 x 8 = 32, rectangle has area of 32 squared cm

Add up the areas:

(24 x 2) + (48 x 2) + (32 x 2) = 208

The rectangle has a surface area of 208 squared cm
