A=bh
330=22h
all you gotta do is divide by 22 on both sides
330/22=h
H=15
and to test it out do 22*15 which equals 330
Dagney reads at 40 pages an hour, or .75 pages a minute.
it would take 4.5 hours to read the novel
Step-by-step explanation:
angle AOB = x+3
angle AOC = 2x + 11
angle BOC = 4x-7
angle AOC = angle AOB + angle BOC
=> 2x +11 = (x+3) + (4x-7)
2x +11 = 5x - 4
=> 3x = 15
x = 5
subst x = 5 in the given formulas
angle AOB = x +3 =8
angle AOC = 2x + 11 = 21
angle BOC = 4x - 7 = 13
Answer:
84 possible paths
Step-by-step explanation:
Given
--- 3 blocks north
--- 6 blocks east
Required
Number of distinct path
To solve this question, we make use of the following formula
The above formula implies that;
On a single path, there is a total of m + n steps to get to a particular position, where each path is either in m direction or n direction.
In this case:
So, we have:
Apply combination formula
Expand the numerator
Expand the denominator
<em>Hence, there are 84 possible paths</em>
<em></em>
<em> will also give the same result</em>
(2,-1)(8,4)
slope = (4-(-1) / (8-2) = (4 + 1)/6 = 5/6
y - y1 = m(x - x1)
(8,4)...x1 = 8 and y1 = 4
slope(m) = 5/6
now we sub
y - 4 = 5/6(x - 8) <==point-slope form
y - 4 = 5/6x - 20/3
y = 5/6x - 20/3 + 4
y = 5/6x -20/3 + 12/3
y = 5/6x - 8/3
-5/6x + y = - 8/3...multiply by -6
5x - 6y = 16 <==standard form
