There are 18 coins total in her bag:
7+3+8=18coins
3 of the 18 coins are dimes, so the odds of first drawing a dime are 3/18
P(dime)=3/18
Since the nickel was taken out and not replaced, there are now 17 coins in her purse.
18-1=17coins
8 of the 17 remaining coins are nickels, so the odds of drawing a nickel are 8/17.
P(nickel)=8/17
Now we multiply the two probabilities by eachother to find out the odds of both occurring...
P(dime)*P(nickel)=
3/18*8/17=24/306=8/103=0.078=8%
The probability of grabbing a dime and then a nickel are 8/103 or 0.078 or an 8% chance, whichever way you'd prefer to write it.
Answer:
they will pay 656 more dollars
Step-by-step explanation:
you multiply 42 by 48 and then subtract it from the full payment
Answer:
See the three examples, below:
Step-by-step explanation:
One way of approaching this would be to separate 48:
48 times 6 is equivalent to (40 + 8) times 6, or 240 + 48, or 288.
That's just one of many examples.
48 times 6 could also be expressed as 48 times (2 + 4) = 96 + 192 = 288.
And so on.
Next time please share more of the instructions. Thank you.
Answer:
c
d
e
Step-by-step explanation:
c) 2(50%)=75%
d) 1=0.75
e) 1=0.75
Joe's Painting: 20x + 100 = y
Steve's Painting: 15x + 120 = y
x = hours worked
y = total income
We can find when the two equations intersect by making them equal to each other. That means we put an equal sign in the middle. So, it would look something like this:
20x + 100 = 15x + 120
First, we have to move the 100 by subtracting it from both sides.
20x = 15x + 120 - (100)
20x = 15x + 20
Then, we need to move the 15x by subtracting it from both sides.
20 - (15x) = 20
5x = 20
Lastly, we need to divide 5 from both sides.
5x = 20/5
x = 4
Therefore, Joe and Steve would have to work for 4 hours in order for their models to be equal to each other.
