Answer:
(1, 3)
Step-by-step explanation:
The solution to any system is where the two lines meet. It would be no solution if the lines were parallel. An ordered pair is written out in the format (x, y).
Answer:
the amount received in change is $0.70
Step-by-step explanation:
The computation of the amount received in change is shown below:
= Given amount - purchased amount
= (3 × 50 + 4 × 20 + 4 × 5) - $249.30
= (150 + 80 + 20) - $249.30
= 250 - 249.30
= $0.70
Hence, the amount received in change is $0.70
Answer:
10•b=120
Step-by-step explanation:
10•b=120 is the equation your looking for, if your trying to find out what the variable equals then b=12
Area = pi x radius squared... so
a = pi x 10in^2
a = 314.159
We notice there are 4B and 4G (shown in the photo)
P(picking 1st a Green) = 4/8 (having picked a green -and not replacing it- the remaining number of marbles is 3G + 4B)
P(picking 2nd a Green) =3/7
P(picking 1st green AND picking 2nd Green )=(4/8) x (3/7) = 12/56≈ 0.21=21%
