Answer : Each grade level will be 30,60,90,30 respectively.

Explanation:

Since we have given that ratio of freshman to sophomores to juniors to seniors in band is 1:2:3:2

Let the number of fresh man be x

Let the number of sophomores be 2x

Let the number of juniors be 3x

Let the number of seniors be 2x

According to question,

x+2x+3x+2x=240

⇒8x=240

⇒x=\frac{240}{8}

⇒x=30

So, the required number of freshman is 30

Number of sophomores is 2×30=60

Number of juniors is 3×30=90

Number of seniors is 2×30=60

Answer:

60 yd

Step-by-step explanation:

Volume is length x width x height. Therefore in this case, we do 4x3x5 which turns out to be 60. Also don't forget to add yd after your answer because this is measured in yards.

In the diagram below, ΔABC is inscribed in circle P. The distances from the center of circle P to each side of the triangle are
4vir4ik [10]
Supposing the sides with 6 and 8 is a right angle, you can create a new line from C and P, and find the length using the equation of a²+b²=c² or 6²+8²=c², with c equaling the radius of the circle.

After finding c, you will have to find the length from C to the midpoint of AC, using the same equation a²+b²=c². If both the lengths of C to the midpoint of AC, and A to the midpoint of AC are equal, you can do b+b to find the length of AC.

Using the same approach, you can find AB. Hope this makes sense, if not, I can clarify more.

What is the area of this figure? Please help.
Ad libitum [116K]

The area of the composite figure can be found by summing the whole area that made up the figure. Therefore, the area of the figure is 213.5m²

<h3>Area of a composite figure</h3>

The area of the composite figure is the sum of the area of the whole figure.

Therefore, the composite figure can be divided into 2 triangles and two rectangles.

Hence,

area of triangle1 = 1 / 2 × 10 × 13 = 65 m²

area of the triangle2 = 1 / 2 × 15 × 7 = 52.5 m²

area of the rectangle1 = 8 × 3 = 24 m²

area of rectangle2 = 7 × 6 = 42 m²

area of rectangle3 = 5 × 6 = 30 m²

Therefore,

area of the composite figure = 65 + 52.5 + 24 + 42 + 30 = 213.5 meters squared
