To solve this problem, simply use one variable to represent the number of students in each of the 2 classes.
1st class - X = no of students
2nd class - X + 6 no of students
Both classes : X + X + 6 = 50
2X + 6 = 50
2X = 44
X = 22.
1st class - X = 22 students
2nd class - X + 6 = 22 + 6 = 28 students.
There are 28 students in the larger class.
Volume of a cylinder= (height) x area of the base (circle)
We know the height = 160 cm (given), let's find the radius of the base.
The circumference of the base = 87.92 = 2πR==> R=87.92/(2π) =13.993 cm
Area of circle = πR²=π(13.993)² = 615.128 cm²
Hence the volume of the cylinder = 615.128 x 160 = 92,420.48 cm³
Answer:
Step-by-step explanation:
to decrease a number by 40% i would do
100% = number you got
50% divide by 2
10%= dived 100% number by 10 then take the 10% away from the 50% to get 40%
then take the 40% away from the 100%
hope this helps :)
Answer:
Step-by-step explanation:
The given line has equation:
3x-5y=7
We need to determine the slope of this line, so we rewrite in slope intercept form.
The slope of this line , when we compare to y=mx+c is
All parallel lines have the same slope.
Hence our line also has the same slope
This line passes through (-10,8).
The equation is given by:
We substitute the slope and point to get:
We expand to get:
