1 answer:

6 0

Area of a circumference=π*r²for diameter=21.2 cm---------> r=10.6 cmA=π*10.6²--------> A=π*112.36 -------> A=352.81 cm²if 2π radians (full circumference) has an area of -----------------> 352.81 cm² 3π/5 radians-------------------------------------> XX=[(3π/5)*(352.81)]/2π---------> X=105.84 cm²

The manager of music is giving away 255 music downloads at its grand opening event.

Andreas93 [3]

30 people will receive 1 music download each.

<u>Solution: </u>

Given, the manager of music is giving away 255 music downloads at its grand opening event.

The manger gave the greatest possible number of music downloads to each of the first 75 customers,

Now, suppose, manager gave 4 downloads each for first 75 customers.

Then, total downloads = 75 x 4 = 300 downloads, which is greater than 255, so giving 4 to 1st 75 is not possible.

Now, suppose, he gave 3 to each customer, then total downloads = 75 x 3 = 225, it is possible

So, manager will give 3 downloads each to 1st 75 customers.

Then remaining downloads = 255 – 225 = 30 downloads, then 30 people can use them.

Hence, 30 people will receive 1 music download each.

Milan puts 1/4 of her lawn mowing money savings and uses 1/2 of the remaining money to pay back her sister.If she has 15$ left,

Feliz [49]

Answer:

$40

Step-by-step explanation:

Let the amount of money she has at first be $x.

She put 1/4 for savings, this means she decides to spend 3/4. The 3/4 is equivalent to (3/4)x

Now, she puts half of the money not saved to pay back her sister and has $15 left.

This means the (3/4)x is equivalent to $30. This is because she used half which is $15 to pay back her sister.

Now, since (3/4)x equals 30, we calculate x

(0.75)x = 30

x = 30/0.75 = $40

She originally had $40
