Answer: (for 11b) 15/6
Step-by-step explanation:
I added image of how I solved (I’m 99% sure this is right)
Hope this helps :-))
Volume for a cone is 1/3 pi * r^2*h, where r is radius and h is height.
We have diameter = 1/2 radius. Thus, radius = 1.5in. We also have volume is 12 in.
Using formula for volume of a cone and plugging in what we know, we have
12 = 1/3*pi*(1.5)^2*h, were solving for h.
To get, h= (12*3)/(pi*(1.5)^2), which is approximately 5.0931in, 5 inches
Answer:
26
Step-by-step explanation:
[(7+3)5-4]/2+3
-To solve this equation you have to use PEMDAS
P- Parentheses
E- Exponents
M- Multiplication
D- Division
A- Addition
S- Subtraction-
- With MD and AS you work left to right of the equation since they are in the same spot. (PE[MD][AS])
Step 1) [(10)5-4]/2+3
- First you do "P," parentheses, so you add 7+3=10
Step 2) [50-4]/2+3
- Next you do "M," multiplication, and multiply 10x5=50
Step 3) [46]/2+3
- Then you do "S," subtraction, and subtract 50-4=46
(FYI: Steps 1-3 were still in the parentheses. We had to start with the parentheses in the parentheses, work PEMDAS, and now we are out of the parentheses and have to work PEMDAS on the rest of the problem.)
Step 4) 23+3
- Now we do "D," division, and divide 46/2=23
Step 5) 23+3=6
- Finally we do "A," addition, and add 23+3=26 so the answer is 26
(FYI: "/" means division)
Answer:
It will have one solution.
Step-by-step explanation:
The line will meet at a point if extended to give a unique solution.
