There are 25 grandparents there were in the survey. 4 prefered digital copies, 21 prefered hard copies. 

4/25 prefered digital copies
21/25 prefered hard copies

21 is more than 4. 
The only one of the possible answers that imply that more people prefered hard copies was the third option. Therefore, "More grandparents prefer using a hard copy than a digital copy." is the correct answer.

I would say you could definitely  eliminate number 1 because 4 and 21 are not the same . Lets go to number 2 now that might not be possible  so lets check it out just to check so 21 grandparents for hard copy is not less than the grandparents that want to use digital copy which is 4 so we cross that out. Number 3 is your answer because we can tell since 21 grandparents want to use a hard copy than digital therefore that is your answer 21 is greater than 4

What is the area of the shaded portion of the circle?
iren2701 [21]

Answer:

1st option

Step-by-step explanation:

the area of the shaded portion is calculated as

area of sector - area of white Δ

area of sector = area of circle × fraction of circle

                        = πr² × \frac{90}{360} ( r is the radius )

                        = π × 8² × \frac{1}{4}

                       = 64π × \frac{1}{4}

                       = 16π in²

area of Δ = \frac{1}{2} bh ( b is the base and h the perpendicular height )

here b = h = 8

area of Δ = \frac{1}{2} × 8 × 8 = \frac{1}{2} × 64 = 32 in²

then

area of shaded portion = (16π - 32 ) in²

Plz help me this question plz plz help plz help me all four of them plzzzz
garik1379 [7]

Answer:

10) The equation of a line parallel to y=-3 passing through the coordinate (2,6) is y=6

11) The equation of a line perpendicular to y=-3 passing through the coordinate (2,6) is x=6

12) The equation of a line parallel to x=4 passing through the coordinate (-2,3) is x=-2

13) The equation of a line perpendicular to x=4 passing through the coordinate (-2,3) is y=3

Step-by-step explanation:

For any line parallel to X-axis the equation we have

y=a

where a is the y coordinate.

∴  The equation of a line parallel to y=-3 passing through the coordinate (2,6) is y=6

For any line parallel to Y-axis the equation we have

x=b

Where b is the x coordinate.

∴ The equation of a line parallel to x=4 passing through the coordinate (-2,3) is x=-2

For any line perpendicular to X-axis is parallel to Y axis therefore the equation we have

x=b

∴ The equation of a line perpendicular to y=-3 passing through the coordinate (2,6) is x=6

For any line perpendicular to Y-axis is parallel to X axis therefore the equation we have

y=a

∴  The equation of a line perpendicular to x=4 passing through the coordinate (-2,3) is y=3
