Volume =


multiply r by 2 and you will get diameter
Y=kx is the direct variation equation
First plug in the x, y values given to find K
18=k(5)
18/5=k
3.6 = k
Use the k and write a new equation.
y=3.6x
Plug in the x value to solve for y.
y = 3.6(11)
y= 39.6
That's what it will look like
Area of a triangle is calculated by using the formula A=1/2bh
A= 1/2 (8.2) (5)
A=1/2 (41)
A=20.5 or 20 1/2, whichever way you think your teacher wants it.
Answer:
212 tickets were sold
Step-by-step explanation:
a (adult) + s (student) = 326
8a + 5s = 1972
-5(a + s = 326)
-5a-5s=1630
3a/3 = 342/3
a = 114
114 + s = 326
s = 212
