Step-by-step explanation:

this is a set problem (mathematical set)

30 students played soccer

9 students played cricket and soccer

x students played neither cricket nor soccer

3x students played cricket only.

we can see that in the first set 21 appears and in the middle of the set 9 because it says 30 students played soccer adding x and 3x we have the following formula

30 + x + 3x = 50 where x is equal to 5 then ask us Determine the number of students who played cricket. then the value would be 3x + 9 = (3x5) + 9 = 24

Find the arc length of the partial circle.

amid [387]

The arc length of the partial circle is 7.5π

<h3>Calculating arc length</h3>

From the question, we are to determine the arc length of the partial circle

The length of an arc can be calculated by using the formula

$l = \frac{\theta}{360^\circ} \times 2\pi r$

Where $l$ is the length of the arc

$\theta$ is the angle subtended

and r is the radius

From the diagram,

θ = 270°

r = 5

Putting the values into the equation, we get

$l = \frac{270 ^\circ}{360^\circ} \times 2\pi \times 5$

$l = \frac{3}{4} \times 2\pi \times 5$

$l = \frac{30\pi}{4}$

$l = \frac{15}{2}\pi$ OR 7.5π

Hence, the arc length of the partial circle is 7.5π

A new gold phone has different prices for different types....

Rzqust [24]

So,

The range will simply be the absolute value of the difference between the highest and lowest price.

The highest price is $2285.

The lowest price is $1116.

The absolute value of the difference between these two prices is:

|2285 - 1116| = 1169

The range of the prices for the gold phone is $1169.

You can buy 2 DVDs for the same price you would pay for 3 CDs selling for $13.20 a piece.Explain how you could find the price of

egoroff_w [7]

So,

3 CD's sell for $13.20 each.
3 * 13.20 = $39.60

$39.60 is also the price for 2 DVD's.

Divide $39.60 by 2.
$19.80

Each DVD is $19.80.
