iragen [17]

Answer:

There were 4 adults; including Mr. Torres

Step-by-step explanation:

- Each row in the stadium had 9 seats

- Mr. Torres sat by himself; he sat on a row with nobody else (no students, no adults)

- The arrangement of the students and the adults who sat with them on same row is:   A  S  S  S  A  S  S  S  A

              1   2  3  4  5  6  7  8  9

since 1 adult sat at each end of a/the row and each group of 3 students was seated between 2 adults.

So the total number of adults that were present = 3 + 1 = 4

The cost of painting the rectangular board with a semicircular top is $31.065 to the nearest hundredth.

<h3>How to find the area of the composite figures?</h3>

To find area of the composite figures,

  • Separate the figure.
  • Calculate the are of the each figure by which the composite figure is made of.
  • Add the area of all the individual figures to get the total area of composite figures.

The dimentions of the rectangle is 3 by 4 foot. The area of the rectangle is,

A_r=3\times4\\A_r=12\rm \;ft^2

The radius of the semicircle is 1.5 m. The area of the semicircle is,

A_{sc}=\dfrac{1}{2}\pi\times(1.5)^2\\A_{sc}=\dfrac{1}{2}(3.14)\times(1.5)^2\\A_{sc}=3.5325\rm\; ft^2

The area of the composite figure is,

A=12+3.5325\\A=15.5325\rm\;ft^2\\

The rate of  painting is $2.00 per square foot. Thus the cost to paint the figure is,

A=15.5325\times2\\A=31.065

Hence, the cost of painting the rectangular board with a semicircular top is $31.065 to the nearest hundredth.

Find the value of x.
Margaret [11]

Answer:

x = 10

Step-by-step explanation:

note that sin30° = \frac{1}{2}

Since the triangle is right use the sine ratio to find x

sin30° = \frac{opposite}{hypotenuse} = \frac{5}{x}

multiply both sides by x

x × \frac{1}{2} = 5 ( multiply both sides by 2 )

x = 10
