Answer:

4 Juniors play the trumpet

Step-by-step explanation:

Given the following information:

percent of the band members that are Juniors: 24%

In 50 members of the band, 50*24/100 = 12 are Juniors. One third of them play the trumpet, that makes 12*(1/3) = 4 members.

Answer:

12

Step-by-step explanation:

You must first divide 50 by 100 to get what 1% of 50 would be (0.5). You can then take 0.5 and multiply it by 24 and you will get 12.

Tema [17]

Answer:

21 in^{2}

Step-by-step explanation:

The square in the middle has a length and width of 3, so multiply. <u>9</u>.

All of the triangles have a base of 3 and a height of 2. The area equation for triangles is

A=bh\frac{1}{2}

So base*height is 6. Divide that by 2 or multiply by 1/2.

You get 3. There are 4 triangles, so multiply <em>that</em> by 4. <u>12</u>.

Add 12 and 9 together, and you get:

21 in^{2}

I hope this helps!

Ganezh [65]

Answer: area is 286.16 ft²

Step-by-step explanation:

Length of the sand pit is 29.2 feet and the width is 9.8 feet.

L= 29.2 ft

W = 9.8 ft

To find out the area, all we have to do is multiply the lenght by the width:

And do not forget that to calculate the area, all units must be the same and for the area, it is always the unit squared, in this case, feet square or simply (ft²).

A = l*w

A = 29.2 * 9.8 = 286.16 ft²
