Answer:
560 downloads of standard version downloads.
Step-by-step explanation:
Let there were number of standard version of downloads = x
and number of high quality version of downloads = y
There were total 950 downloads of the both type of songs.
x + y = 950 -----(1)
Size of the standard version songs = 2.8 MB
and the size of the high quality version songs = 4.4 MB
Total download size = 3284 MB
2.8x + 4.4y = 3284
7x + 11y = 8210 -----(2)
Multiply equation (1) by 11 (-) equation (2)
(11x + 11y) - (7x + 11y) = 10450 - 8210
4x = 2240
x = 560
There were 560 downloads of the standard version downloads.
Answer:
4π/3 square units
Step-by-step explanation:
Triangle XYZ is equilateral,
The central angle of the sector is 120°, or 2π/3 radians.
The area of a sector of central angle β is given by
.. A = (1/2)r^2*β . . . . . . β in radians
.. A = (1/2)*2^2*(2π/3) = 4π/3 square units
