a web music store offers two version of a popular song. the size of the standard version is 2.9 megabytes (MB). the size of the
miv72 [106K]

Answer: 260 downloads of the standard version were there.

Step-by-step explanation:

Let x represent the number of downloads of the standard version.

Let y represent the number of downloads of the high-quality version.

Yesterday, the high-quality version downloaded four times as often as the standard version. It means that

y = 4x

The size of the standard version is 2.9 megabytes (MB). the size of the high-quality version is 4.6 MB. the total size downloaded for the two versions was 5538 MB. It means that

2.9x + 4.6y = 5538- - - - - - - - - - - -1

Substituting y = 4x into equation 1, it becomes

2.9x + 4.6 × 4x = 5538

2.9x + 18.4x = 5538

21.3x = 5538

x = 5538/21.3

x = 260

Find the area of the figure.
Ivanshal [37]

Step-by-step explanation:

Area of Rectangle at the top =

Length x Width

= 3.5 \times 3 \\  = 10.5 {mm}^{2}

Area of Quarter- Circle = 1/4 x Area of Circle

=  \frac{1}{4} \pi {r}^{2}  \\  =  \frac{1}{4} \pi( {3.5}^{2} ) \\  = 3 \frac{1}{16} \pi {mm}^{2}

Area of Rectangle at the right = Length x Width

= 5.5 \times 3.5 \\  = 19.25 {mm}^{2}

Total Area = Area of 2 Rectangles + Area of Quarter Circle

= 10.5 + 3 \frac{1}{16} \pi + 19.25 \\  = 29.75 + 3  \frac{1}{16}\pi  \\  = 32  \frac{13}{16}\pi {mm}^{2}

I will leave the answer in terms of pi as I'm not sure if you need to round off your answer.
