Answer:
20 containers
Step-by-step explanation:
Given:
D = 0.07N
Where,
D = Amount of deposits
N = Number of containers
If D = $1.40 find N
D = 0.07N
1.40 = 0.07N
Divide both sides by 0.07
N = 1.40 / 0.07
= 20
N = 20 containers
if you deposit $1.40, you will buy a total of 20 containers.
Answer:
Step-by-step explanation:
From the coordinate geometry, equation of line that passes through two coordinates will be
y-y1 ={(y2-y1)/x2-x1)}(x-x2) where x1=3,y1= -2, x2 =6, y2 = 3. therefore substitute for the values
y-(-2) ={ 3-(-2)/6-3} x (x-6)
y+2 = 3+2/3 x (x-6)
y+2 =5/3(x-6) multiply both side by 3,
3(y+2) = 5(x-6)
3y+6 =5x-30
3y = 5x -30 -6
3y = 5x - 36. Therefore the equation of the line is
3y = 5x - 36.
Answer:
b = A/h
Step-by-step explanation:
A = bh
Divide both sides by h
A/h = b
b = A/h
Answer:
