If on March 8, 2017 , one U.S. dollar worth 66.79 Indian rupees
ie. $1 = Rs 66.79
$ 1 = 66.79 × 1
$ ? = 110.66
$ = New / old
$ = 110.66 / 66.79
$ = 1.65683485552
or
$1.66 = 110.66
Answer:
51 Adult tickets were sold that day.
Step-by-step explanation:
Let c = child and a = adult
c + a = 148 5.50c + 9.00a = 992.50
Change the first equation so that it is either in the form c = or a =and then plug that number into the second equation.
I am going to change the first equation to c = by subtracting a from both sides
c = 148 - a
Now I am going to plug 148 -a for c in the second equation.
5.5(148 - a) + 9a = 992.5 Next distribute the 5.5
814 - 5.5a + 9 a = 992.5 Add the a terms together
814 + 3.5a = 992.5 Subtract 814 from both sides
3.5a = 178.5 Divide both sides by 3.5
a = 51
Answer:
Drew is incorrect. She forgot to take the reciprocal of -1/6. Drew just did (3/4)(-1/6) which got her -3/24 instead -9/2.
Step-by-step explanation:
Same, change, reciprocal:
(3/4)(-6/1)=-18/4=-9/2.
Given:
The equation of a line is
...(i)
The perpendicular line passes through the point (-1,4).
To find:
The equation of the perpendicular line.
Solution:
The slope intercept form of a line is:
...(ii)
Where, m is the slope and b is the y-intercept.
On comparing (i) and (ii), we get
Product of slopes of two perpendicular lines is -1.
Let the slope of perpendicular line is .
The slope of the perpendicular line is and it passes through the point (-1,4). So, the equation of the line is:
Add 4 on both sides.
Therefore, the equation of required line is .
