$4.55 my dude. You add them together and subtract the sum from 20
Answer:
I dont mind :D These were my favorite! They are actually really simple. Dont overthink it. It even gave you a hint!
It says a^2 + b^2 = c^2
We can substitute what we do have which is a = 10 and c = 15
10^2 + b^2 = 15^2
Now we square it
100 + b^2 = 225
Next, all we have to do is subtract the 100 from our answer so 225-100 which is 125, so b has to be 125!!! Because 125 + 100 is 225 :D
Step-by-step explanation:
Answer:
V = 1384.7 or 1385.4
(look at explanation)
Step-by-step explanation:
V = pi r^2 (h)
V = pi (49) (9)
V = pi (441)
V = 1384.74 if pi is 3.14
if pi is longer
V = 1385.44236
Answer:
1) Term - Terms are the elements separated by the plus or minus signs.
2) Coefficient - Coefficient is a number that is being multiplied by the variable.
3) Variable - A variable is a letter or symbol used as a placeholder for an unknown value.
