Mr.Utley’s class has a greater band to chorus student ratio
Step-by-step explanation:
Step 1 :
Number of students in band in Mrs.Washington’s class = 2 for every 3 students in chorus.
Number of students in band in Mr.Utley’s class class = 5 for every 7 students in chorus.
Hence
the ratio of band students to chorus students in Mrs.Washington’s class = 2 : 3
the ratio of band students to chorus students in Mr.Utley’s class = 5 : 7
We need to determine which is the greater ratio
Step 2 :
Ratio 1 = 2: 3
Ratio 2 = 5:7
Converting to common denominator we have
Ratio 1 = 14 : 21 and ratio 2 = 15:21
So the ratio 15:21 = 5:7 of Mr.Utley’s class is greater
Step 3 :
Answer :
Mr.Utley’s class has a greater band to chorus student ratio
Answer:
<em>The equation of the straight line in point - slope form</em>
<em>y +1 = -2 ( x-2)</em>
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given points are C( 2,-1) and D(1,1)
Slope of the line
m = -2
<u>Step(ii):-</u>
Equation of the straight line passing through the point ( 2,-1) and having slope
m =-2
y - y₁ = m ( x- x₁)
y - (-1) = -2 ( x-2)
y +1 = -2 ( x-2)
<u><em>Final answer:-</em></u>
<em>The equation of the straight line</em>
<em>y +1 = -2 ( x-2)</em>
