Answer:
B
Step-by-step explanation:
Replacing <em>f</em>(x) with 21, this is the equation
21=3x+9
First, subtract 9 from each side of the equation to get:
12 = 3x
Next, divide each side by 3 to get:
4 = x
So the answer is B.
Answer:
14ft
First get the cones volume formula v=(3.14*r^2*h)/3
Second find the radius which is 1/2 the diameter.
Third plug in given and solve 366= (3.14*5^2*h)/3
366*3=3*(3.14*25*h)/3
1098=78.5h
1098/78.5=78.5h/78.5
13.987=h
Answer:
Speed
Step-by-step explanation:
To find the distance the formula is d=st. Where d is the distance, s is speed, and t is time. So in the equation, 3 must be the speed of the snail.
