I have to assume that the instructions are to "simplify <span>-5+7m-20=20-2m."

If that's the case:

Group like terms together:  7m + 2m = 20 +5 + 20
                                                9m      = 45
                                                  m   =  5 (answer)</span>

Solving this for r, we get

... A/π = r²

... r = √(A/π) . . . . . formula for the radius

For your given area, the radius is approximately

... r = √(401.92/3.14) = √128 = 8√2

... r ≈ 11.3 . . . yards

If I roll two six-sides dice, what is the probability that the sum of the numbers that show up on the dice is 3 or less?
liq [111]

Answer:

1/12

Step-by-step explanation:

first we have to find all the possibilities of getting a sum of 3 or less: 1+1 or 1+2 and we count the second combination 2 times because the numbers can be on either of the dices so we have a total of 3 possibilities. all the possible pairimg of dice are 6*6=36 because each dice has 6 sides and we can get either of them. so the probability would be the chance of getting a sum of 3 or less divided by all the diff combination which equals 3/36 or 1/12 which is roughly around 8.3%
