Answer:12, 7
Step-by-step explanation:Using the process of elimination, I went through each number and subtracted five and added it until I got 12 and 7.
Answer:
10 visors
Step-by-step explanation:
Make an equation
Each visor, v costs $6, and there is a $5 fee regardless of the amount of visors purchased. This must be equal to $65
6v+5=65
Now, solve for v
Subtract 5 from both sides
6v=60
Divide both sides by 6
v=10
You can buy 10 visors
I did not even understand that equation
The formula for volume of a sphere is V=(4pi*r^3)/3.
Plugging in 12 for r we get
V=(4pi*(12)^3)/3
V=(4pi*1728)/3
V=(6912pi)/3
V=2304pi
Round to 2 decimal places: 7238.23
Final Answer:
7238.23 cubic units.
Hope I helped :)
Answer: 2a - 7
<u>Step-by-step explanation:</u>
Ana: a
Mrs Vargas: 4a - 4
Leo: 2a + 3
Mrs Vargas - Leo
= (4a - 4) - (2a + 3)
= 4a - 4 -2a - 3
= 2a - 7
