Step-by-step explanation:
2πrh+2πr²=surface area
2π(3)(6)+2π(3²)
36π+18π
54π
Answer:
3 because when x=2 the lines are at y 1 and 3, but the y 1 isn't shaded, so the answer is 3
Answer: 7/12 portion
Explanation:
Jack can paint:
1 house = 3hr
1/3 portion= 1hr
Jill can paint:
1 house = 4hr
1/4 portion = 1hr
Both of them together can paint in 1 hour:
1/3 + 1/4 = 3/12 + 4/12 = 7/12 portion in 1hr
Answer:
f(x) = -7x + 1
Step-by-step explanation:
Slope intercept form is
y = mx + b
m is slope
b is y-intercept
--------------------------
y decreases by 7 for each increase of 1 in x
slope = -7
to find "b" plug in one of the points and m = -7
using point (3, -20)
y = mx + b
-20 = -7(3) + b
-20 = -21 + b
b = 1
The equation is
f(x) = -7x + 1
So he’s eaten 2/3 already
make a rectangle with three sections
shade in two of the sections
and that shows how much of the granola bar he’s eaten
