Yes, for fractions you can multiply the denominator by the numerator. For square roots you can use the square root button.
circumference of circle= 2x3.14r
1) radius is 9
2x3.14x9
18x3.14= 56.52
2) radius is 8
2x3.14x8
16x3.14= 50.24
3) radius is 5
2x3.14x5
10x3.14= 31.4
Y=Mx+b (m is slope, b is y-intercept)
Answer:
4
Step-by-step explanation:
Given:
64 total students
x = drama club students
y = yearbook club students
x = y + 10
y = 64 - x
y = 64 - x
y = 64 - (y + 10)
y = 64 - y - 10
y + y = 64 - 10
2y = 54
2y/2 = 54/2
y = 27
x = y + 10
x = 27 + 10
x = 37
To check:
x + y = 64
37 + 27 = 64
64 = 64
