We know that ratios can be shown with both fractions and colons.
20:705
or

It also looks like we can simplify this by dividing by 5.
20/5 = 4
705/5 = 141.
This means that for every 4 teachers, there are 141 students.
The ratio for teachers to students is:
4 : 141
<span>4.5 : 9% = 4.5 / (9 : 100) = (100 * 4.5) / 9 = 50</span>
Answer:
Distance: 8.5440037453175
Step-by-step explanation:
Distance: 8.5440037453175
Steps:
Distance (d) = √(-7 - -10)2 + (-1 - -9)2
= √(3)2 + (8)2
= √73
= 8.5440037453175
Slope and Angle:
ΔX = -7 – -10 = 3
ΔY = -1 – -9 = 8
Slope (m) =
ΔY
ΔX
=

= 2.6666666666667
θ =
arctan( ΔY )
ΔX
= 69.443954780417°
Equation of the line:
y = 2.6666666666667x + 17.666666666667
or
y =

When x=0, y = 17.666666666667
When y=0, x = -6.625
Answer:
the answer is 2/9.
Step-by-step explanation:
8/9÷4
= 8/9 × 1/4
= 8/36
=2/9
