Answer: Choice D) 7.21 units
-----------------------------------------------------------------------------------------------
Work Shown:
Using the distance formula, we get
d = sqrt( (x2-x1)^2 + (y2-y1)^2 )
d = sqrt( (1-(-3))^2 + (-3-3)^2 )
d = sqrt( (1+4)^2 + (-3-3)^2 )
d = sqrt( (4)^2 + (-6)^2 )
d = sqrt( 16 + 36 )
d = sqrt( 52 )
d = 7.21110255 *** see note below ***
d = 7.21
Note: Use a calculator with a square root function. The value is approximate.
Answer:
20%
Step-by-step explanation:
To find the decimal answer, we just do 5/25 which is equivalent to 0.2
Then, we multiply 0.2 by 100 to get the percentage:
0.2*100=20
25/5 = 5
and also
15/3 = 5
so
(3x+ 8)/5 = 4
3x + 8 = 20
3x = 12
x = 12/3
x = 4
answer is x = 4
Let x be number of downloads of standard version and y be number of downloads of high quality versions.
The hight quality downloads are twice as the standar downloads. So,
The downloaded data for x standard version is 2.7x and for y high quality version is 4.2y. The total downloaded data is 3219. So,
Substitute 2x for y in the equation and solve the obtained equation for x.
So value of x is 290. Thus downloads of the standard version were 290.
Answer: 290
