Unit rate = 75 pages/45 minutes = 1 1/3 pages/minute
Time to read 425 pages = Total number of pages/Unit rate = 425/1 1/3 =255 minutes = 4 hours and 15 minutes.
Answer:
Im prety sure the lenghths double aswell. But it also means that the width has doubled.
Step-by-step explanation:
If you take a moment and solve each equation (find the value
of the letter in each one), it'll jump out at you.
Here, let me do it for you. Why should you tire yourself.
5x = 20 . . . . . x = 4
4b = 7 . . . . . . b = 7/4
8w = 32 . . . . . w = 4
12y = 48 . . . . . y = 4
The second equation is not like the others.
It's the only one where the letter is not equal to 4 .
X² - 4x = x² - 4x + (
)² - (
)²
x² - 4x = x² - 4x + (2)² - (2)²
2² = 4
The constant term that is missing is
4
Answer:
Option (4)
Step-by-step explanation:
Slope a line passing through two points and is given by,
m =
Since, blue line is passing through two points (-4, -2) and (0, 4),
Slope of the blue line =
=
Similarly, green line is passing through two points (-4, 1) and (0, -2),
Slope of the green line =
=
Since,
Neither these slopes are opposite reciprocals.
Therefore, both the lines are neither parallel nor perpendicular.
Option (4) will be the correct option.
