For every _8_ books sold there were _2_ movies sold OR
For every _4_ books sold there were _1_ movies sold
| r + 3 | > 7
r + 3 > 7 r + 3 < -7
r > 7 - 3 r < -7 - 3
r > 4 r < -10
so, r > 4 and r < -10
==========================
what percent of 60 is 12
percent formula : is/of = %/100
percent = x
is = 12
of = 60
now sub
12/60 = x/100
cross multiply
60x = 12 * 100
60x = 1200
x = 1200/60
x = 20%
Answer:
-5m-1
Step-by-step explanation:
You have to multiply the negative sign by 5m and 1.
(-)(5m)= -5m
(-)(1)= -1
-5m - 1
Given:
The equations are:
To find:
The equation that show the relationship between a and c.
Solution:
We have,
...(i)
...(ii)
Equation (i) can be rewritten as:
...(iii)
From (ii) and (iii), we get
Therefore, the required equation is .
Answer:
The correct option is:
cosθ = -3/5
Step-by-step explanation:
We have been given that:
cotθ = 3/4
such that the terminal side of θ lies in III quadrant.
Consider it a right angled triangle.
We know that:
cotθ = Base / Perpendicular
Which means Base has a magnitude of 3 and Perpendicular has the magnitude of 4.
As It lies in III quadrant, both x and y are negative.
So
Base = -3
Perpendicular = -4
Find the hypotenuse by using Pythagoras Theorem
H² = (-3)² + (-4)²
H = 5
We know that:
cosθ = Base / Hypotenuse
cosθ = -3/5
